What is mineralocorticoid?
Mineralocorticoid is a type of steroid hormone that produces the adrenal glands. Found in the upper part of the kidneys and the outer part of each gland, adrenal glands or adrenal glands, they exclude a group of hormones known as corticosteroids, of which mineralocorticoids are one type. Mineralocorticoids are steroids responsible for regulating the balance of the body fluid and the concentration of minerals such as potassium and sodium. The main mineralocorticoid produced by the adrenal glands is called aldosterone and affects the level of sodium in the blood. Higher sodium levels mean more water into the blood, which increases blood volume and blood pressure. More sodium is reabsorbed into the blood, which means that less is removed from the body in the urine. Along with an increase in sodium reabsorption, more water is issued, which increases the UID FLOD and blood volume in circulation. Another effect of aldosterone is that more potassium leaves the body in the urine and less is reabsorbed by the kidneys. The activity of mineralocorticoid aldosterone also inhibits the loss of sodium from salivary and sweat glands, whichIt causes taste buds to be more sensitive to salt and causes the absorption of elevated sodium inside the colon.
When sodium levels in the blood reduce or increase potassium levels, it stimulates the adrenal cortex to release more aldosterone. In particular, potassium affects the secretion of mineralocorticoids, with only a very small increase in blood potassium to release more aldosterone. If blood pressure drops, the substance known as angiotensin II also affects the adrenal glands to increase the production of aldosterone.
Mineralocorticoids are necessary for a person to remain alive. Aldosterone's defense is potentially fatal because it leads to low blood pressure and heart failure. Mineralocorticoid deficiencies may be caused by addison disease or hypoadrenocorticism. In addition to Addison's disease, the immune system attacks cells producing mineralocorticoids in the adrenal cortex and other cells,that produce so -called glucocorticoids such as cortisol. Cortisol, like aldosterone, helps to regulate blood pressure, but also regulates blood sugar and affects the body's response to stress and infection.
Treatment of Addison's disease from the necessary preventing serious illness and death. The condition is controlled by the giving of drugs to replace the missing mineralocorticoids and glucocorticoid hormones. In treatment, the view can be quite positive for people with addison with an expected lifetime that is almost average.
