The question of how to increase the lower pressure without increasing the upper one is often asked by patients to doctors. There is no unequivocal answer to it, since a variety of reasons can underlie the decrease in diastolic pressure..

Low blood pressure, although unpleasant, is rarely associated with severe pathology. Blood pressure is the pressure that blood exerts on the walls of the arteries.. This important hemodynamic indicator includes three parameters:.

Systolic (upper, heart) pressure. At the time of systole (contraction), the heart pushes a certain portion of blood into the aorta, which, at the moment of movement through the arterial vessels, affects their walls. The strength of this effect is called systolic pressure..

Diastolic (lower, renal) pressure. When moving, the blood experiences a certain resistance from the walls of blood vessels.. The more elastic the vessels, the less pronounced this resistance, the faster the myocardium relaxes and the lower the diastolic pressure. The tone of blood vessels is greatly influenced by the biologically active substance synthesized by the kidneys - renin.. And therefore, the second value of blood pressure is sometimes called renal.

Pulse pressure. It is the difference between upper and lower pressure, expressed in the same way as systolic and diastolic pressure - in millimeters of mercury (mmHg. st.

In clinical practice, an isolated decrease in diastolic pressure is observed extremely rarely, in no more than 2-3% of cases, and in the remaining 97-98% of cases, hypotension is due to a simultaneous decrease in both upper and lower pressure.

Causes of Low Diastolic Pressure Low blood pressure is called hypotension.. Most often, there is a synchronous decrease in both systolic and diastolic pressure.. But sometimes situations are observed when the upper pressure remains normal or even slightly increased, and the lower one decreases, for example, in a person, the pressure can be 120/50 mm Hg. st. The following pathological processes can lead to the development of this condition:.

shock states;

renal or heart failure;

dysfunction of the valve apparatus of the heart or contractile activity of the myocardium;

heart rhythm disturbances;

severe allergic reactions;

severe anemia;

hyperthyroidism;

peptic ulcer of the stomach and duodenum;

severe hypovitaminosis;

malignant neoplasms;

volumetric blood loss;

violations of water and electrolyte balance;

long-term adherence to an overly strict low-calorie diet or mono diet.

What to do with a low diastolic pressure If a patient has a low low blood pressure, in this case it is necessary:.

assess his general condition;

conduct an examination and identify the cause of this condition;

to carry out treatment aimed at normalizing blood pressure levels.

Let's consider each of these points in more detail..

Evaluation of the patient's condition A decrease in diastolic pressure may be accompanied by the onset of certain symptoms or proceed without them..

If a person does not have any malaise and diastolic hypotension is detected only as a result of tonometry, treatment, as a rule, is not required, since doctors consider this condition as a variant of the physiological norm.

It is impossible to predict how, during therapy, an increase in lower pressure will occur (simultaneously with systolic or in isolation). Therefore, self-medication is unacceptable..

Significant difference between systolic and diastolic pressure (over 40-60 mm Hg. st. ) is often accompanied by the appearance of general weakness, headache, dizziness. In this situation, you do not need to wonder how to quickly raise the lower pressure at home, but you need to urgently consult a doctor, since the reason can be very serious.
