Low blood pressure is defined as the value of blood pressure that is lower than normally expected for a single person in the given conditions and is a relative term. Blood pressure values vary depending on activity, age, medication and health. Blood pressure that is borderline low for one person may be normal for another.
The views of doctors differ - from those that low blood pressure are not considered disease to those who hold potentially serious, well-defined condition that requires treatment and control.
In the German medical literature in a patient with constitutional hypotension to define blood pressure less than 100/60 mmHg measured several times in the outpatient setting with the presence of symptoms (fatigue, difficulty sleeping, dizziness, fainting, anxiety or depression, feeling a strong heartbeat, sweating) and absence other diseases / causes other symptoms. Besides permanently present low blood pressure (primary chronic, idiopathic or constitutional hypotension) which can not detect the cause, there is a secondary hypotension caused by various diseases, conditions and medications, and acute conditions with a sudden drop in blood priiska of which are orthostatic (postural) hypotension and postprandial the most common. Orthostatic or postural hypotension is a drop in blood pressure when moving to a standing position, postprandial hypotension is a sudden drop in blood pressure after meals. Such acute falls in blood pressure occur in persons otherwise normal blood pressure.
If the blood pressure is too high can damage blood vessels and even cause their cracking (rupture), causing bleeding and other complications. If too low, sufficient amount of blood is out of all parts of the body - all the cells do not receive enough oxygen and food and waste products are removed sufficiently.Nevertheless, low blood priisak is generally considered better than high blood pressure. Healthy persons within the normal range have lower blood pressure live longer than people with higher blood pressure.
Persistent low blood pressure is rarely an indicator of serious health disorders, the body can adapt to it, and often causes no symptoms. The problem arises with the sudden drop in pressure when the brain and other vital organs are left without supply and no time to adjust. In such a case may arise dizziness, body weakness, impaired vision and even a brief fainting (syncope).
Persistent low blood pressure which can not detect the cause is called primary, idiopathic or constitutional hypotension. Studies show the incidence of this condition in a population of about 0.3-4% and twice the incidence in women. Apart from hereditary factors, studies show significant effects of geographic areas, food (especially the amount of salt in food), weight loss, exercise and stress on blood pressure.
Treatment is aimed at facilitating the achievement of the above symptoms and blood pressure of 100 mmHg. Treatment is not necessary if low blood pressure causes no symptoms or reduce the quality of life.The network of treatment are as follows:
First the most important person to convince, despite the presence of symptoms that impair quality of life for a good prognosis of primary hypertension.
Second Measures include increasing dietary intake of salt
Third compression socks (socks that squeeze the legs) - because the increased intake of salt can lead to accumulation of fluid in the legs
4th getting out of bed should be gradually
5th increase physical activity
7th If the measures described above do not lead to elevated blood pressure satisfactory relief of symptoms and the doctor recommended medication. Although not conclusive research results available to a possible therapeutic regimen including dihydroergotamine, etilefrine, amezinium, or a combination of carefully adding mineralocorticoid.
Hypotension may be due to a number of causes, various medical disorders and drugs and then talk about the secondary hypotension. Conditions that can cause low pressure are: - bleeding, infection, dehydration, and various heart disease - heart attacks, arrhythmias, pericardial disease, adrenal insufficiency, pregnancy, poisoning, allergic reactions, particularly anaphylaxis, changes position from lying to standing (postural / orthostatic hypotension ), stroke, shock, pressure drop after the performance of small and / or bowel movements, loss of pressure after eating (postprandial hypotension), anxiety, Parkinson's disease, neuropathy, hemodialysis, burns, severe diabetes.
Treatment depends on the secondary causes of hypertension. In this case, low blood pressure is a consequence of primary disorders, treatment / removal of the causes can be solved by low blood pressure.
