Hypotension, Hypotension

Hypotension, Hypotension

Terms used in biology and medicine to denote a reduced level of fluid pressure (blood, lymph) in the vessels and a decrease in muscle tension. It is most correct to use the term “hypotension” to denote a decrease in the level of blood (or lymph) pressure, and the term “hypotension” to denote a decrease in the level of muscle tension. However, it must be remembered that the term “hypotension” often still refers only to low blood pressure.

Arterial hypotension is a decrease in blood pressure levels beyond the age norm. Such a decrease in blood pressure, requiring emergency treatment. help, occurs with acute blood loss (internal or external bleeding), is a manifestation of collapse, and sometimes occurs at high body temperature.

Persistent (chronic) hypotension may be a symptom of rare hormonal deficiency. Some practically healthy individuals have a relatively low level of blood pressure - on the verge of normal, but inclined to fluctuate mainly in the direction of decrease; in this case, they often talk about arterial hypotension and even hypotension. The existence of the latter is still debatable.

Persons of the mentioned category differ only in that they have a predominance of hypotensive rather than hypertensive cardiovascular reactions. In everyday life, these people often note that they tolerate hot weather worse than cold weather, that they feel bad in the bathhouse, that they sometimes experience darkening in their eyes (even fainting) when suddenly moving from a horizontal to a vertical position, especially on an empty stomach, and, on the contrary , feel good when walking, during muscle activity. This is explained by the fact that in hypotensive vascular reactions the leading role is played by a slightly reduced tone of the venous vessels, which have a greater total capacity than the arteries and in which in such cases a certain part of the circulating blood is easily retained.

The return of this part of the blood to the heart is delayed, as it were, reducing cardiac output, because during contraction the heart throws into the aorta exactly as much blood as it returns to it through the veins.

Return blood flow through the veins directly depends on the activity of skeletal muscles, which, through their contractions, propel blood to the heart. People with hypotensive reactions need systematic treatment. muscular activity that creates and maintains tone of the main muscle groups of the human body.

A physically developed, active person, not burdened with excess body weight, extremely rarely experiences hypotensive reactions. Persons with a known predisposition to hypotensive reactions, with age, as well as during periods of forced inactivity, especially due to illness, often tend to add drinks such as freshly brewed tea containing natural tonic substances to their diet, and there is no reason to prevent them. In addition, sometimes the doctor recommends in such cases the ingestion of medications, also of natural origin, as a rule, but more accurately dosed.
