Several other factors may be involved in the development of low blood pressure:
- Dehydration: When the body doesn’t have enough water, the amount of blood in the body (blood volume) decreases.
- Diabetes (because it can damage the nervous system).
- Pregnancy: it’s common for blood pressure to drop during the first 24 weeks of pregnancy.
- Nutritional deficiencies: A lack of the vitamin B12 and folic acid can cause anemia, which in turn can lead to low blood pressure.
- Drugs.
- Excessive alcohol consumption.
- Prolonged exposure to heat.
- Diseases that affect the nervous system, such as Parkinson’s disease or multiple sclerosis.
- Prolonged bed rest.
- Certain medications (antidepressants, anxiolytics, neuroleptics ….).
- Cardiovascular problems – stroke, heart failure, myocardial infarction, irregular heart rhythms (arrhythmias).
- Insufficiency of the adrenal gland.
- Diseases of the thyroid gland.
- Large blood loss from a major trauma, dehydration or severe internal bleeding. As blood volume reduces dramatically, it causes a severe drop in blood pressure, and can be the cause of a shock.
- Important varicose veins: It is possible that a large amount of blood can stagnate in the varicose veins.
- Head trauma.
- Anaphylactic shock.
- An infectious disease.
