Hypotension means low blood pressure

Hypotension means low blood pressure.

If blood pressure drops below dangerous limits, as can occur in major bleeding, in the so-called shock that may be due to severe heart problems, very serious infections, and others, hypotension can be life-threatening.


It consists of dizziness, or even very frequent loss of consciousness, which occurs when you stand up quickly from a sitting position. It is more frequent after being in the sun for a long time, or after a prolonged fast.

If you suffer from orthostatic hypotension, avoid these situations.

In any case, if you have suffered one or more syncopes or dizziness, you should consult the doctor, who will decide if you have one to be evaluated, or not, by a particular specialist.

A permanently low blood pressure can be inherited. The so-called essential hypotension (ie, primary hypotension) is the most common form and usually affects young and thin women. It is not clear why the pressure remains so low. However, the trend may be hereditary so that both mother and daughter are often affected. If no symptoms occur, the essential hypotension is harmless. In fact, it can protect against diseases caused by hypertension. The risk of developing blood vessel sclerosis (atherosclerosis) and its consequences, such as coronary heart disease, myocardial infarction, stroke or peripheral occlusive diseases, is lower in this case.

Secondary hypotension refers to a low blood pressure that is a consequence of a disease or action of a drug.

The diseases that can cause hypotension are:

• Thyroid hypofunction (hypothyroidism)
• Hypofunction of adrenal cortex (Addison’s disease)
• Hypofunction of the pituitary gland (insufficiency of the anterior lobe of the pituitary gland)
• Heart disease (such as heart failure, rhythm disorders, pericarditis, for example)
• Keep bed for an extended period of time
• Deficit of fluid (hypovolemia)
• Lack of salt (hyponatremia)

Drugs that can cause hypotension are:

• Psychotropes (against depression, anguish, insomnia)
• Antiarrhythmics (against cardiac arrhythmias)
• Antihypertensives (against high blood pressure)
• Diuretics (diuretic drugs)
• Coronary drugs (in the case of angina pectoris, such as nitrite spirals)
• Vasodilators

Psychotropes (against depression, anguish, insomnia)
In the case of orthostatic hypotension (ortostasis = straight position), blood is crowded into the lower parts of the body when sitting or standing up quickly. For a short time, the brain receives less blood. Dizziness may occur and, in the worst case, a mildew. This type of low blood pressure often occurs along with secondary hypotension. However, in many cases the cause of circulatory problems can be ascertained by the Schellong test.

Possible causes of orthostatic hypotension are:

• Secondary hypotension
• Disorders of the autonomic nervous system (caused by diabetes, for example)
• Damage to brain neurons (caused by certain forms of Parkinson’s disease and hydrocephalus, alcoholism, for example)
• Post-thrombotic syndrome (after deep venous thrombosis in the legs)
• Veins with varicose veins (varicosis)
