Renin Angiotensin Aldosterone System
 
03:43
This animation focuses on the renin angiotensin aldosterone system (RAAS), a classic endocrine system that helps to regulate long-term blood pressure and extracellular volume in the body. Many aspects of cardiovascular disease progression can be directly linked to the RAAS system. Mechanisms such as vascular inflammation, generation of reactive oxygen species and alterations of endothelial function are all known to play a role in atherosclerosis.

Renin angiotensin system regulates blood pressure

If in the US use this link http://goo.gl/mDMfj5 If in the UK use this link http://goo.gl/j0htQ5 One of the proteins present in the blood is called angiotensinogen. This is a short protein produced by the liver and is inactive; it just circulates in the blood. However, when renin acts on angiotensinogen it converts it into another shorter protein called angiotensin I. As angiotensin I passes through the lungs it is converted into angiotensin II by an enzyme called angiotensin converting enzyme (ACE). Angiotensin II is a powerful vascular vasoconstrictor; this will increase peripheral resistance which will in turn increase blood pressure. In addition to increasing BP by direct vasoconstriction angiotensin II also stimulates the secretion of aldosterone from the adrenal cortex. This will increasethe amount of sodium reabsorbed from the renal tubules and so increase levels of sodium in the blood. As mentioned, increased levels of sodium increases the osmotic potential of the blood and so it attracts more water. This means more water is retained in the plasma increasing blood volumes. These increased volumes will increase venous return and so blood pressure. Conversely, lower amounts of angiotensin II will reduce aldosterone secretion leading to more sodium excretion. This will lower sodium levels in the blood leading to lowered blood volumes and so lower BP. If the systemic blood pressure is increased the pressure in the afferent arteriole will also be increased. This will be detected by the JGA cells which will respond by reducing renin secretion. When less renin is present in the blood, more angeotensionogen will remain in inactive form. This renin-angiotensin-aldosterone mechanism allows the kidneys to regulate their own blood flow to an extent. When an organ regulates itself in this way it is called autoregulation. If for any reason the kidneys over-secrete renin blood pressure will be raised. An abnormally high BP is termed hypertension. Renin excess probably explains most cases of chronic hypertension. You may have come across ACE inhibiting drugs; these inhibit ACE (angiotensin converting enzyme) and so inhibit the conversion of angiotensin I into angiotensin II. If there is less angiotensin II there will be less vasoconstriction and less secretion of aldosterone and so blood pressure will be lowered.

Water Regulation by Antidiuretic Hormone (ADH)
 
06:22
Water Regulation by Antidiuretic Hormone (ADH)/ Antidiuretic Hormone animation/Antidiuretic Hormone mechanism/Antidiuretic Hormone physiology/Antidiuretic Hormone function The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys. As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. The hypothalamus controls the mechanisms of ADH secretion, either by regulating blood volume or the concentration of water in the blood. Dehydration or physiological stress can cause an increase of osmolarity above 300 mOsm/L, which in turn, raises ADH secretion and water will be retained, causing an increase in blood pressure. ADH travels in the bloodstream to the kidneys. Once at the kidneys, ADH changes the kidneys to become more permeable to water by temporarily inserting water channels, aquaporins, into the kidney tubules. Water moves out of the kidney tubules through the aquaporins, reducing urine volume. The water is reabsorbed into the capillaries lowering blood osmolarity back toward normal. As blood osmolarity decreases, a negative feedback mechanism reduces osmoreceptor activity in the hypothalamus, and ADH secretion is reduced. ADH release can be reduced by certain substances, including alcohol, which can cause increased urine production and dehydration.

Plasma renin then cuts a short, 10 amino acid long, peptide off a plasma protein known as angiotensinogen. The short peptide is known as angiotensin I.[2] Angiotensin I is then converted, by the removal of 2 amino acids, to form an octapeptide known as angiotensin II, by the enzyme angiotensin-converting enzyme (ACE) found in the lung capillaries. Angiotensin II is a potent vaso-active peptide that causes arterioles to constrict, resulting in increased arterial blood pressure.[3] Angiotensin II also stimulates the secretion of the hormone aldosterone from the adrenal cortex.[3] Aldosterone causes the tubular epithelial cells of the kidneys to increase the reabsorption of sodium ions from the tubular fluid back into the blood, while at the same time causing them to excrete potassium ions into the tubular fluid which will become urine. RELATED TOPICS renin catalysis protein chemical compound organic compound endocrine system polymer blood pressure angiotensin enzyme Renin-angiotensin system, physiological system that regulates blood pressure Renin is an enzyme secreted into the blood from specialized cells that encircle the arterioles at the entrance to the glomeruli of the kidneys (the renal capillary networks that are the filtration units of the kidney). The renin-secreting cells, which compose the juxtaglomerular apparatus, are sensitive to changes in blood flow and blood pressure. The primary stimulus for increased renin secretion is decreased blood flow to the kidneys, which may be caused by loss of sodium and water (as a result of diarrhea, persistent vomiting, or excessive perspiration) or by narrowing of a renal artery. Renin catalyzes the conversion of a plasma protein called angiotensinogen into a decapeptide (consisting of 10 amino acids) called angiotensin I. An enzyme in the serum called angiotensin-converting enzyme (ACE) then converts angiotensin I into an octapeptide (consisting of eight amino acids) called angiotensin II. Angiotensin II acts via receptors in the adrenal glands to stimulate the secretion of aldosterone, which stimulates salt and water reabsorption by the kidneys, and the constriction of small arteries (arterioles), which causes an increase in blood pressure. Angiotensin II further constricts blood vessels through its inhibitory actions on the reuptake into nerve terminals of the hormone norepinephrine.

Always seek the advice of a qualified healthcare provider with any questions you may have regarding a medical condition. Blood pressure is the force the circulating blood EXERTS on the walls of blood vessels. It is different in different types of vessels, but the term ”blood pressure”, when not specified otherwise, refers to ARTERIAL pressure in the SYSTEMIC circulation. When the heart contracts and pumps blood into the aorta, during systole, the aortic pressure RISES, and so does the systemic arterial pressure. The maximum pressure following an ejection is called the SYSTOLIC pressure. In between heart beats, when the ventricles refill, blood pressure FALLS to its lowest value called the DIASTOLIC pressure. THESE are the 2 numbers on a blood pressure reading. Blood pressure normally shows a daily pattern and is usually lower at night. During day-time, it fluctuates with physical activities and emotional states. Hypertension refers to a PERSISTENT HIGH blood pressure. In the US, high blood pressure used to be defined as greater than 140/90, but recent guidelines have changed these values to 130/80 to better prevent and treat the condition. Normal blood pressure is BELOW 120/80. In practice, blood pressure is considered TOO low ONLY if it produces symptoms. Hypertension does NOT cause symptoms on its own, but it slowly DAMAGES blood vessels, and in the long-term, is a MAJOR risk factor for a variety of cardiovascular diseases such as stroke, aneurysm and heart attack; as well as end organ damage such as renal failure or vision loss. For this reason, hypertension is known as the “SILENT killer”. Hypertension can be classified as primary or secondary, with the former being responsible for over 90% of cases. Primary hypertension has NO apparent cause and may develop as a result of old age, obesity, high-salt diet, lack of exercise, smoking and drinking. Most commonly, the blood vessels are hardened with age or unhealthy diets, making it harder for blood to flow. Secondary hypertension, on the other hand, is caused by an underlying condition. Many conditions and factors can cause hypertension; most notable are kidney problems and endocrine disturbances. Regardless of the cause, the INcrease in blood pressure is produced by EITHER an INcrease in vascular resistance - narrower or stiffer blood vessels; OR an INcrease in cardiac output – larger volume of blood pumped out by the heart. These 2 factors are the targets of antihypertensive drugs. Treatments must start with life style changes such as healthy, low-sodium diets, physical exercise and stress management. On top of that, antihypertensive agents may be used to control hypertension. These include: - Vasodilators: these drugs DILATE blood vessels, thereby DEcreasing vascular resistance and reducing blood pressure. - Diuretics: diuretics promote sodium and water removal by the kidneys and thereby DEcrease blood volume. - Drugs that DEcrease cardiac output by decreasing heart rate or contractility, may also be used to treat hypertension.

What is Hyperaldosteronism   Causes, Dangers, and Treatments
 
10:03
Books about hyperaldosteronism - http://amzn.to/2gPJ3FJ What is hyperaldosteronism? What is aldosterone? What is renin angiotensin? Aldosterone helps control blood pressure by holding onto salt and losing potassium from the blood. The increased salt increases the blood pressure. Hyperaldosteronism is a disease in which the adrenal gland(s) make too much aldosterone which leads to hypertension (high blood pressure) and low blood potassium levels. Primary hyperaldosteronism can be caused by either hyperactivity in one adrenal gland (unilateral disease) or both (bilateral disease). Unilateral disease is usually caused by an aldosterone producing adenoma (benign tumor) and less commonly by adrenal cancer or hyperplasia (when the whole gland is hyperactive). Bilateral disease is usually caused by bilateral hyperplasia (when both glands are hyperactive). There are rare genetic syndromes like familial hyperaldosteronism type I and II which may cause both glands to be hyperactive.

Low Blood Pressure caused by Adrenal Fatigue
 
06:03
https://www.drlam.com/blog/signs-symptoms-low-blood-pressure-causes-correlation-adrenal-fatigue/19097/ This is Dr. Lam, founder of DrLam.com and today we are going to talk about low blood pressure consistently. Now, blood pressure is an automatically regulated mechanism in our body. It is designed to provide oxygen through blood, through our brain, as well as various parts of our body. The regulation of blood pressure falls within many factors. Blood volume can effect the blood pressure, the endothelial wall of the blood vessel itself constricting and dialating through what we call baroreceptors or blood pressure sensitive receptors can help modulate the blood pressure, and of course electrolytes and the sodium balance can also play an important factor. The organs responsible including the kidneys, the adrenals, as well as the brain, can also make a big factor in regulating the blood pressure on a 24/7 basis without us knowing. Of course we can not discount the role that the heart plays as well. So maintaining normal blood pressure is a very important part of survival. Just going from a sitting to a standing position requires that it activates all the systems in various degrees so that we can stand up, not feel dizzy, and are able to walk and not feel dizzy and then have normal activity. Any time the blood pressure is not regular the brain is not getting enough profusion or blood flow, and then the body will suffer. In the case of adrenal fatigue, what happens is, because the adrenal glands regulate the sodium and potassium balance, there is a tendancy, as the adrenals get weaker, that the body is not able to regulate this as much as it should. As a result, the sodium is usually lost through the deficieny or the subclinical effectiveness of aldosterone: the hormone that is regulating the blood flow and the water flow. Now this hormone is critical because in adrenal fatigue this hormone aldosterone tends to be low. As a result the sodium is not going to be easily maintained in the body. At this time the labratory values may be the same, or when I say the same I mean normal. People come in a lot of them with low blood pressure because they are losing sodium, and without sodium your water does not flow. So in other words the water stays with the sodium, wherever the sodium goes the water goes. So as long as the sodium is high the water will be retained in the body. When the sodium is low then the body will tend to lose water, and if you lose water, then your blood pressure will go down; it will stay down consistently. That is why many people with low blood pressure tend to do better when they eat more salt they can be perked up and feel much better. But of course, you have to be careful because too much salt can lead to another set of problems including hypertension, as well as swelling in the legs, what we call edema. So first we have to understand that low blood pressure is a symptom and not a disease. Number two you have to look at the big picture of how everything else comes together. In an adrenal fatigue situation, oftentimes low blood pressure does not stand alone; it comes along with other clinical signs and symptoms that you have to put the pieces together. It is one of many symptoms that presents itself. Usually the more advanced the adrenal fatigue the more prominent this is. A very interesting thing that you also have to understand is that in the early stages of adrenal fatigue, blood pressure tends to rise because of the vessel constriction of blood vessels narrowing as a result of hormones; and then in later stages it tends to go down. So if you look at the blood pressure, it can be high and still have adrenal fatigue in early stages, if it stays low consistently then it could mean the body is in a state of advanced adrenal fatigue if all other medical workup is normal. So, low blood pressure constistently is an important symptom to look for in adrenal fatigue and it points us to the underlying dysfunction that is maybe happening in the adrenal glands.

Take Dr. Berg's Advanced Evaluation Quiz: http://bit.ly/EvalQuiz Your report will then be sent via email analyzing 104 potential symptoms, giving you a much deeper insight into the cause-effect relationship of your body issues. It's free and very enlightening. Dr. Berg talks about the symptoms of high cortisol versus low cortisol. Your adrenals might start out with high cortisol due to stress, then trigger the cell receptors to downgrade and develop cortisol receptor resistance or glucocorticoid receptor resistance. This makes the adrenal make more cortisol. This could lead to chronic fatigue, chronic inflammation, low stress tolerance, high blood pressure, blood sugar problems, high cholesterol and belly fat.

Thyroid Hormone Regulation and Negative Feedback
 
03:18
In humans and other mammals, thyroid hormone regulates bioenergetics; helps maintain normal blood pressure, heart rate, and muscle tone; and regulates digestive and reproduc- tive functions. If the level of thyroid hormone in the blood drops, the hypothalamus responds by initiating a hormone cascade pathway . The hypothalamus secretes thyrotropin-releasing hormone (TRH), causing the anterior pituitary to secrete a tropic hormone known as either thyroid-stimulating hormone (TSH) or thyrotropin. TSH stimulates release of thyroid hormone by the thyroid gland, an organ in the neck consisting of two lobes on the ventral surface of the trachea. As thyroid hormone accumulates, it increases metabolic rate, while also initiating negative feed- back that prevents its overproduction. CAMPBELL 10th Edition

The dangers of low blood pressure
 
06:49
Most people worry about high blood pressure, and with good reason as it portends numerous health risks, such as the possibility of an increased risk of heart attacks and strokes. But… Low blood pressure brings a different set of problems, such as reduced brain function and increased mortality risk. If the upper or lower number deviates by more than 10 from 120/80, it pays to be aware low blood pressure may be affecting your health. Think of it like this. The function of your blood pressure is to push the blood out of your blood vessels by permeating out of them to the rest of the body. High blood pressure is often a compensatory response to something that is going on in the body. If you cover up the end response of your body you can get other symptoms. Such as, a very common side effect of blood pressure medications is brain fog or mental “unclarity”. Which really makes perfect sense. Your brain is now not getting the blood (or oxygen) it needs to function, which equals……uhhhhhhhh? What? As a side note I often find that in the elderly, if they have not taken care of themselves and their arteries are already starting to harden, this will lead to decreased permeability of the blood vessels. As a result, blood pressure goes up to compensate and get blood to the brain. If you lower blood pressure too much, you no think too much! ;-) Blood pressure pushes blood through about 100,000 miles of veins, arteries, and capillaries in the body, carrying oxygen, nutrients, immune cells, hormones, neurotransmitters, and other vital compounds. High blood pressure strains blood vessels. However, low blood pressure means not enough blood is getting to capillaries and tissues, particularly in your hands, feet, and brain. This deprives those tissues of sufficient oxygen and nutrients. You may have chronic nail fungal infections and cold hands and feet if so. These can also be signs of an immune system that is deficient as well. So it pays to check both. Adrenal fatigue as a cause of low blood pressure The most common cause of low blood pressure (other than taking blood pressure medications) in a functional medicine model is poor adrenal function. The adrenals are two walnut-sized glands that sit atop the kidneys. They produce stress hormones and help regulate blood pressure. Many people today suffer from adrenal fatigue due to chronic stress. Other causes of adrenal fatigue are poor diets, low blood sugar, chronic infections, gut problems, inflammation, and unmanaged autoimmunity — all stressors.

Adrenal Glands: Help Them Out By Slowing Down | Dr. Weston
 
03:40
Adrenal glands are teeny endocrine glands that sit at the top of the kidneys. The adrenal glands produce dozens of powerful hormones that help control heart rate, regulate blood pressure, and balance blood sugar levels. But what happens when good glands go bad? As much as 80% of the public are affected by adrenal fatigue, which is caused by constant stress, making the adrenal glands work improperly. Do you feel overwhelmed and exhausted? Do you have difficulty concentrating? Feel nervousness, anxiety, or depression? You too may have adrenal fatigue. So help those glands out by slowing down. Much like exercising without rest can cause muscle fatigue, being constantly on the go, go, go can cause adrenal fatigue. Eat whole foods rich in vitamins C, E, and B. Get adequate sleep. Cut down on alcohol, caffeine, and sugar. And, most important, take a breath, slow down, and don't overstress yourself. -- Subscribe to our channel: http://www.youtube.com/subscription_center?add_user=sunwarriortribe -- Visit us at: http://www.sunwarrior.com/ Like us on Facebook: http://www.facebook.com/sunwarrior ‪Follow us on Twitter: http://twitter.com/Sunwarrior Hang out with us on Google+: http://plus.google.com/100431369190586473063/posts Follow us on Pinterest: https://pinterest.com/sunwarriortribe/

2-Minute Neuroscience: Hypothalamus & Pituitary Gland
 
02:01
In my 2-Minute Neuroscience videos I explain neuroscience topics in 2 minutes or less. In this video, I cover the hypothalamus and pituitary gland. I discuss the two major roles of the hypothalamus: homeostasis and hormones. I also explain how the hypothalamus controls hormone release by manipulating the pituitary gland. I cover the anterior and posterior lobes of the pituitary gland, along with the most common hormones secreted from each lobe. For more neuroscience articles, videos, and a complete neuroscience glossary, check out my website at www.neuroscientificallychallenged.com ! TRANSCRIPT: Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics in 2 minutes or less. In this installment I will discuss the hypothalamus and pituitary gland. The hypothalamus is a small region situated directly above the brainstem. It is made up of a collection of nuclei with a variety of functions, but in general the hypothalamus is involved in controlling the two H’s: homeostasis and hormones. Homeostasis is a term used to describe the maintenance of balance or stability in a biological system. The hypothalamus can maintain homeostasis either by exerting direct influence over the autonomic nervous system, or by causing the release of hormones. The hypothalamus manipulates hormone release primarily by controlling the pituitary gland. The pituitary gland is a hormone-secreting gland that sits just below the hypothalamus. It is sometimes called the “master gland” because it not only secretes many extremely important hormones but it also regulates the activity of other hormone-secreting glands throughout the body. The pituitary consists of two lobes, called the anterior and the posterior pituitary. The anterior pituitary is responsible for the release of a number of hormones that have widespread effects throughout the body. They include growth hormone, which is involved with growth, follicle-stimulating hormone, which plays a role in development and reproduction, luteinizing hormone, which is essential to testosterone production and reproduction, adrenocorticotropic hormone, which is involved with the stress/fear response, thyroid sTimulating hormone, which is important to healthy metabolism, and prolactin, which promotes milk production in females. The release of these hormones is controlled by the hypothalamus, which sends signals in the form of releasing hormones to tell the anterior pituitary when to secrete its hormones. The posterior pituitary also secretes two hormones, but does not synthesize them. Instead, they are synthesized by the hypothalamus and then sent to the posterior pituitary for release into the bloodstream. The names of these hormones are: oxytocin and vasopressin. Oxytocin has important roles in facilitating childbirth and lactation, but is also thought to have a role in compassion and social bonding. Vasopressin's main functions are to control urine output and regulate blood pressure.
How Does Pituitary Gland Work? Hormones of Hypophysis Functions & Disorders Animation -TSH FSH Video
 
03:00
The pituitary gland is often referred to as the "master gland" of the body, since it regulates many activities of other endocrine glands. Located above the pituitary gland is the hypothalamus. The hypothalamus decides which hormones the pituitary should release by sending it either hormonal or electrical messages. In response to hormonal messages from the hypothalamus, the pituitary gland releases the following hormones: GH (growth hormone) – increases size of muscle and bone TSH (thyroid stimulating hormone) – stimulates the thyroid gland to release T3 and T4 to stimulate metabolism in other cells throughout the body FSH (follicle stimulating hormone) – stimulates ovarian follicle production in women; stimulates sperm production in men LH (luteinizing hormone) – stimulates ovaries to produce estrogen in women; stimulates sperm production in men Prolactin – stimulates breast tissue in nursing mothers to produce milk ACTH (adrenocorticotropic hormone) - causes the adrenal glands to produce important substances that have properties similar to steroids In response to electrical messages from the hypothalamus, the pituitary gland releases the following hormones: ADH (antidiuretic hormone) - stimulates the kidneys to reabsorb fluid and produce less urine Oxytocin – initiates labor, uterine contractions and milk ejection in mothers The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea and weighing 0.5 grams (0.018 oz) in humans. It is a protrusion off the bottom of the hypothalamus at the base of the brain. The hypophysis rests upon the hypophysial fossa of the sphenoid bone in the center of the middle cranial fossa and is surrounded by a small bony cavity (sella turcica) covered by a dural fold (diaphragma sellae). The anterior pituitary (or adenohypophysis) is a lobe of the gland that regulates several physiological processes (including stress, growth, reproduction, and lactation). The intermediate lobe synthesizes and secretes melanocyte-stimulating hormone. The posterior pituitary (or neurohypophysis) is a lobe of the gland that is functionally connected to the hypothalamus by the median eminence via a small tube called the pituitary stalk Hormones secreted from the pituitary gland help control the following body processes: Growth Blood pressure Some aspects of pregnancy and childbirth including stimulation of uterine contractions during childbirth Breast milk production Sex organ functions in both males and females Thyroid gland function The conversion of food into energy (metabolism) Water and osmolarity regulation in the body Water balance via the control of reabsorption of water by the kidneys Temperature regulation Pain relief Sleeping patterns (pineal gland) Some of the diseases involving the pituitary gland are: Central diabetes insipidus caused by a deficiency of vasopressin. Gigantism and acromegaly caused by an excess of growth hormone in childhood and adult respectively. Hypothyroidism caused by a deficiency of thyroid-stimulating hormone. Hyperpituitarism, the increased (hyper) secretion of one or more of the hormones normally produced by the pituitary gland. Hypopituitarism, the decreased (hypo) secretion of one or more of the hormones normally produced by the pituitary gland. Panhypopituitarism a decreased secretion of most of the pituitary hormones. Pituitary tumours. Pituitary adenomas, noncancerous tumors that occur in the pituitary gland. Somatotrophins: Human growth hormone (HGH), also referred to as 'growth hormone' (GH), and also as somatotropin, is released under the influence of hypothalamic growth hormone-releasing hormone (GHRH), and is inhibited by hypothalamic somatostatin Thyrotrophins: Thyroid-stimulating hormone (TSH), is released under the influence of hypothalamic thyrotropin-releasing hormone (TRH) and is inhibited by somatostatin. Corticotropins: Adrenocorticotropic hormone (ACTH), and Beta-endorphin are released under the influence of hypothalamic corticotropin-releasing hormone (CRH). Lactotrophins: Prolactin (PRL), also known as 'Luteotropic' hormone (LTH), Gonadotropins: Luteinizing hormone (also referred to as 'Lutropin' or 'LH'). Follicle-stimulating hormone (FSH), both released under influence of Gonadotropin-Releasing Hormone (GnRH) The intermediate lobe synthesizes and secretes the following important endocrine hormone: Melanocyte–stimulating hormone (MSH). This is also produced in the anterior lobe. When produced in the intermediate lobe, MSHs are sometimes called "intermedins". Posterior: Magnocellular Neurons: Antidiuretic hormone (ADH, also known as vasopressin and arginine vasopressin AVP), the majority of which is released from the supraoptic nucleus in the hypothalamus. Oxytocin, most of which is released from the paraventricular nucleus in the hypothalamus.

Blood Vessels: The oxygenated blood entering the aorta is carried by a network of arteries, arterioles and capillaries to the tissues from where the deoxygenated blood is collected by a system of venules, veins and vena cava and emptied into the right atrium. Blood Pressure: Pressure exerted by the flow of blood on the walls of blood vessels. Normally SBP=120 mm Hg and DBP=80 mm Hg. Regulation of cardiac Activity: A special neural centre in the medulla oblangata can moderate the cardiac function through autonomic nervous system (ANS). Neural signals through the sympathetic nerves (part of ANS) can increase the rate of heart beat, the strength of ventricular contraction and thereby the cardiac output. On the other hand, parasympathetic neural signals (another component of ANS) decrease the rate of heart beat, speed of conduction of action potential and thereby the cardiac output. ...................................................................................

Why Do People With Acromegaly Have Hypertension?
 
02:30
Why Do People With Acromegaly Have Hypertension? There is one organ which causes high blood pressure (and it's not what you think!) and there are specific exercises you can use to target and fix your blood pressure easily. No diet, lifestyle changes or medication required: http://hibloodpressure.stream/ Answers from: Kristie Leong M.D. Youre absolutely right people with acromegaly have ahigher incidence of hypertension. Acromegaly is a condition where the portion of the brain called the pituitary gland produces too much growth hormone, usually due to a non-cancerous tumor of the pituitary gland. In one study, 42% of people who had acromegaly also had hypertension. What Causes Acromegaly, People who have acromegaly secrete too much growth hormoneas well as another related compound produced by the liver called IGF-1. Growth hormone and IGF-1 cause cartilage, bone, and other tissues to grow larger. As a result, people with acromegaly often experience joint pain, hand and feet swelling, joint pain, and enlarged facial features: Why is high blood pressure so common with this condition? Thetheory is that overproduction of growth hormone and IGF-1 causes the renin-angiotensin system to malfunction. This is a system at the level of the kidney that helps regulate blood pressure and fluid balance. When this happens, you begin retaining water and sodium and blood pressure goes. up. Another Reason Why Hypertension is More Common People with acromegaly can also develop insulin resistance and blood sugar abnormalities. As a result, people with this condition have higher levels of insulin in their bloodstream. This is another possible contributor to the elevation in blood pressure you see with acromegaly: The higher blood pressure places extra strain on the heart, particularly the left ventricle since it has to pump against tight arteries and more resistance. As a result, people with acromegaly can develop an enlarged left ventricle. So, heart disease is another complication of acromegaly: Hope this answers your question: References: Nature Reviews Endocrinology 1, 66 (December 2005) |doi: 10.1038/ncpendmet0037.

ADH (Antidiuretic Hormone) / Renal Physiology
 
08:22
ADH (Antidiuretic Hormone) / Renal Physiology/Water Regulation by Antidiuretic Hormone (ADH)/ Antidiuretic Hormone animation/Antidiuretic Hormone mechanism/Antidiuretic Hormone physiology/Antidiuretic Hormone function The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys. As ADH (which is also known as vasopressin) causes direct water reabsorption from the kidney tubules, salts and wastes are concentrated in what will eventually be excreted as urine. The hypothalamus controls the mechanisms of ADH secretion, either by regulating blood volume or the concentration of water in the blood. Dehydration or physiological stress can cause an increase of osmolarity above 300 mOsm/L, which in turn, raises ADH secretion and water will be retained, causing an increase in blood pressure. ADH travels in the bloodstream to the kidneys. Once at the kidneys, ADH changes the kidneys to become more permeable to water by temporarily inserting water channels, aquaporins, into the kidney tubules. Water moves out of the kidney tubules through the aquaporins, reducing urine volume. The water is reabsorbed into the capillaries lowering blood osmolarity back toward normal. As blood osmolarity decreases, a negative feedback mechanism reduces osmoreceptor activity in the hypothalamus, and ADH secretion is reduced. ADH release can be reduced by certain substances, including alcohol, which can cause increased urine production and dehydration.
