When talking about "blood pressure", it usually means high blood pressure (hypertension). High blood pressure is not usually manifested by syQmptoms, but over time causes various damages and its called the "silent killer".

On the other hand, low blood pressure does not usually cause damage such as high blood pressure, but often causes unpleasant Feelings.

 

How to measure blood pressure?

Blood pressure measures in two numerical values: the systolic (high) and diastolic (the low). The first represents the pressure in the arteries during cardiac contraction, While the second represents the blood pressure of your heart at rest..

What values might indicate low blood pressure?

Normal blood pressure values are around 120/80 mm Hg. Values of 90/60 mm Hg and below are considered low.

As mentioned, low blood pressure is not a disease, and when it comes to a healthy person, with no complaints, these values are not important. Lower numbers are typical for women, especially for young and thin ones.

 

Does blood pressure change in different activities?

The body has mechanisms that should maintain proper blood pressure even during rapid posture changes. Naturally in the standing position the blood tends to flow downwards with gravity and accumulate in the legs. When a human changes his position from lying down or sitting to standing up
The body compensation mechanism are contracted the blood vessels to prevent a drop in the blood pressure.

During sleep, blood pressure can decline to values of 80/40 without any damage to the body, Due to the fact that the blood in the supine position can reach the brain and other organs without interruption even when blood pressure is low.

What are the reasons for low blood pressure?

There are many factors for low blood pressure. Sometimes it is a well-known cause like a significant loss of blood in surgery or injury, severe burn or heat stroke. Sometimes this is an ongoing factor that aggravating the problem.

Low blood pressure may be in acute condition and may be on a regular basis (chronic). Acute states include bleeding due to injury, dehydration, diarrhea, and so on.

The reasons for the drop in blood pressure can be divided into several groups:

1. Decreasing the amount of blood and fluids in the body, for example because of bleeding (from injury, disease or circulation) or due to dehydration (for example, due to insufficient drinking on a hot day or due to diarrhea).

2. Reduction in the activity of the heart due to weakening of the heart's activity (e.g., due to the myocardial infarction) or because of the defects in the heart valve. Cardiac arrhythmia, too low or pulse is liable to cause a decrease in blood pressure and reduce heart output.

3. Interference in the autonomic nervous system. This system is responsible, among other things, to the regulating mechanisms of blood pressure, for example, during posture changes. A flaw in this system mainly causes a decrease in blood pressure when a posture is changed into a standing position. This fall in blood pressure following a change in the position is called ortostatism. This eclipse can be caused by a primary problem in the nervous system or because of various diseases that also damage the autonomic nervous system, such as diabetes and Parkinson's.

4. Endocrine disorders (disorders in the regulation of hormones), such as the sub-activity of the thyroid gland or the adrenal insufficiency.

5. Acute conditions such as severe infection (SSIS) or severe allergic reaction (anaphylaxis) cause excessive expansion of blood vessels resulting in a noticeable decrease in blood pressure.

6. Medication. Reduction in blood pressure can be caused, among other things, by excessive doses of hypertension and regular doses of drugs designed to treat urinary incontinence due to enlarged prostate gland or heart failure drugs.

What do you feel when there is low blood pressure?

Low blood pressure is usually characterized by the following symptoms:

1. Fatigue and general weakness.

2. Fast pulse.

3. difficulty concentrating.

4. Headaches.

5. Dizziness and blurred vision.

6. Fainting (in extreme cases)

The faster the drop in blood pressure, the more severe the symptoms. An extreme example is a case of serious injury and considerable blood volume loss within minutes.
How to treat low blood pressure?

When not feeling well, the most important thing is to see a doctor. the doctor can test blood pressure in various conditions (such as lying down, sitting, and standing) to detect a fall in blood pressure in posture changes and refer to various tests as needed. The purpose of the tests is to identify possible causes for the low blood pressure values.

If a specific problem has been identified, it should be tried to balance blood pressure.
When a clear problem is not identified, the main recommendation is to make sure you drink plenty, consume enough salts, and slow and gradual changes in motions. Sometimes using elastic leg bandages reduces blood pressure while standing.

In extreme situations, especially in cases of fainting due to low blood pressure (most often in standing and posture changes), medicines that increase blood pressure can be used.

Pregnant low blood pressure - is this cause for concern?

Blood pressure usually tends to decrease during pregnancy. This is a natural physiological process, so in case of low blood pressure in pregnancy there is no need to worry - as opposed to the condition of high blood pressure in pregnancy. Even if the pregnant woman suffers from dizziness as a result of the drop in blood pressure, it is not recommended to take pills to raise blood pressure.
Self-care tips for low blood pressure

2. It is advisable not to drink alcoholic beverages, as they dilate the blood vessels and may cause further lower blood pressure that is low already.

3. Be sure to drink a lot of water and a diet that includes enough salt (many people try to avoid excessive consumption of salt, and sometimes the result is a small salt intake).
