Excessive secretion of adrenaline

Effects of excessive adrenaline secretion on the human body

Adrenaline is a hormone that the human body must secrete. Adrenaline is very important to the health of the body. It can make the heart contract more advantageously, promote the function of blood vessels throughout the body, improve the body's metabolism, and can be said to be of great help in the treatment of various diseases. If the secretion of adrenaline is normal, the health of the body will be more guaranteed.

At the same time, we also know that although adrenaline secretion is of great help in promoting human health, if adrenaline is secreted too much, it will also have some other effects on human health. So what effects will excessive adrenaline secretion have on human health?

First of all, when people are nervous, the adrenal glands will increase the secretion of adrenaline. As long as you are not nervous, it will be fine. Taking some calcium and magnesium tablets can soothe your nerves, and supplementing vitamin B can relieve stress. The effects of adrenaline: 1. It increases the heart's contractility; dilates the blood vessels in the heart, liver, tendons and bones, and constricts the blood vessels in the skin and mucous membranes. In medicine, adrenaline is used to stimulate the heart in cardiac arrest or to dilate the airways in asthma. Epinephrine can strengthen myocardial contractility, increase excitability, accelerate conduction, and increase cardiac output. The effects on blood vessels in various parts of the body vary not only in strength, but also in contraction or relaxation. 2. It has a constrictive effect on the blood vessels of the skin, mucous membranes and internal organs (such as the kidneys); it has a dilating effect on the coronary arteries and skeletal muscle blood vessels, etc. 3. It can stimulate the β2 receptors of bronchial smooth muscles and exert a powerful diastolic effect. It can also inhibit the release of allergic substances such as histamine from mast cells, and can also cause bronchial mucosal blood vessels to contract, reducing the permeability of capillaries, which is beneficial to eliminate bronchial mucosal edema. 4. It can improve the body's metabolism. Under therapeutic doses, it can increase oxygen consumption by 20% to 30%. In the human body, since the stimulation of α receptors and β2 receptors may cause liver glycogenolysis, and adrenaline has both α and β effects, its effect of increasing blood sugar is more significant than that of norepinephrine. In addition, adrenaline has the effect of reducing glucose uptake by peripheral tissues. Adrenaline can also activate triglyceride enzymes to accelerate fat decomposition and increase free fatty acids in the blood.

It can be said that adrenaline has its advantages and disadvantages, but it can be said that only normal secretion can better promote physical health. Adrenaline can be said to be an indispensable element for physical health, and it is actually of great help in promoting physical health.
