What is hypertension and how to deal with it?

High blood pressure is one of the most common “diseases of civilization”. Its insidiousness lies in the fact that it is not always accompanied by any ailments. But, often remaining unnoticed, it causes great harm to blood vessels and the heart. Hypertension is often the root cause of a stroke or heart attack. Therefore, it is so important to know and control your pressure.

The ideal blood pressure is 120/80 mm Hg. The value in the range of 140/90 – 160/95 is critical and is on the border between the norm and pathology. Do not forget, however, that blood pressure changes many times throughout the day. The lowest rates are usually at night during sleep, and the highest – with high physical and emotional stress.

The body has a complex system of blood pressure regulation, which depends on the correct diet and responds to the slightest changes in the external and internal environment. In the wall of the aorta, the largest vessel, and the carotid artery, there are nerve endings that are sensitive to changes in blood pressure. From these nerve endings, information about the state of blood pressure along the nerve fibers is transmitted to the brain, or rather to that part of the rhomboid brain in which the center responsible for the circulatory system is located. The brain, having processed the received information, sends regulatory signals further.

As a result, the number of heartbeats changes, the vessels narrow or expand, and the production of the hormone renin, which regulates blood volume, is stimulated by the kidneys. Renin, in turn, has a positive effect on the production of the hormone angiotensin, which constricts blood vessels. The synthesis of angiotensin is a signal for increased production of the adrenal hormone aldosterone, which promotes the excretion of potassium ions from the body and the reverse absorption of sodium ions in the kidneys, which leads to a decrease in the excretion of fluid from the body and, thus, to an increase in blood volume, and hence its pressure on vessel walls. An important role in the regulation of blood pressure is played by the so-called stress hormones – adrenaline, histamine, cortisone and acetylcholine. Breakdown of at least one link in this complex regulatory system can lead to chronic hypertension, and subsequently to serious health problems.

The diet of a modern person is overloaded with meat products, animal fats, salted foods, sweets and all kinds of tonic drinks, including alcohol. All this has an extremely negative effect on the cardiovascular system, which already suffers greatly from daily stress and a sedentary lifestyle.

To avoid these problems, you must first change your diet. Healthy nutrition is the basis of hypertension treatment. Eating foods rich in fiber, high in potassium and magnesium helps lower blood pressure. Such foods include persimmons, apricots, bananas, artichokes, legumes, nuts, garlic, spinach, and parsley. It is better to use them raw, as nutrients and vitamins are lost during heat treatment.
