blood pressure
Blood pressure is a measure of the extent of blood flow resistance in arterial walls. Low or low blood pressure is a condition in which arterial blood pressure is low, that is, it is below the normal rate, and most often it is not considered a disease if it does not cause symptoms, or There is no associated condition like heart disease.
Blood pressure is measured in the form of prosthesis and stature, where the upper figure expresses the amount of resistance of blood vessels to blood flow in the case of myocardial contraction and called systolic pressure, and the lower figure reflects the amount of resistance in the case of relaxation of the heart muscle between the pulse and the other is called diastolic pressure.
Normal blood pressure is 120/80 or so. Symptoms of hypotension are evident when blood pressure is less than 90/60. This will deprive the brain and other vital organs of the body of the necessary amounts of oxygen and nutrients, Which may lead to some health problems.
Causes of low blood pressure in general
The causes of low blood pressure vary, some of which are normal due to the person’s lifestyle or nature, and there is an abnormal, symptomatic of a particular disease, or due to some medications, etc., and there are many reasons for the drop in pressure. There are about forty reasons. the reasons.
- Impaired hypotension, a sudden drop in pressure when standing fast.
- The deadly allergic reaction, a violent reaction of the immune system against an allergen, suddenly and dangerously reduces pressure.
- Drought, not drinking enough fluids to compensate for the amount of fluid lost by the body, through sweating and other.
- Shock of hypotension, a life-threatening condition that results from a lack of more than 20% of the blood or body fluids due to severe bleeding, both internal and external bleeding, or severe burns.
- Endocrine diseases in the body, such as thyroid dysfunction, and Addison’s disease.
- Pregnancy, because the blood circulation expands rapidly during pregnancy, which is normal; the pressure returns to normal after birth.
- Low blood sugar (hypoglycemia).
- Heart muscle diseases, such as cardiac arrhythmia, and angina, myocardial infarction, and others.
- Exposure to heat, such as sunstroke, or bathing with very hot water, because this leads to the accumulation of blood in the limbs and under the skin away from vital organs.
- Lack of minerals and salts in the body, such as: vitamin B-12 deficiency, folic acid, iron can cause the condition does not produce the body does not produce enough red blood cells (anemia), causing low blood pressure.
- Acute myelitis.
- Inheritance, where blood pressure in some families is low in heredity.
- Some drugs, such as high pressure medications, some antidepressants, and diuretics.
- Pulmonary thrombus.
- Some neurological diseases, such as Parkinson’s disease.
- Pissing urination, a temporary pressure drop, loss of consciousness due to urination, usually occurs to the elderly as a result of the secretion of certain hormones.
- Vomiting and severe diarrhea.
- Vaginal vasculitis, a condition in which pressure is low and heartbeat is reduced due to exposure to some situations that arouse emotions in the person, such as severe sadness or shocking news.
- Decreased pressure after eating due to gastrointestinal consumption of a large amount of blood in the digestion.
- Exposure to certain types of toxins, such as acetone and chlorine.
- Some bacterial diseases, such as typhoid and plague.
- Some types of cancers, such as pituitary cancers.
- Known as Shy-Drager syndrome: This disorder causes progressive damage to the autonomic nervous system that controls involuntary functions such as blood pressure, heart rate, breathing, and digestion.
- Over-drinking beverages that contain caffeine, such as coffee.
Types of low blood
There are many types of low blood pressure, not uniformly defined, but most of them support the same principle in classification. This is one of the most comprehensive classifications:
- Acute and severe blood pressure, the decline is sudden, and is considered a threat to the patient’s life.
- Decreased hypotension or hypotension: usually occurs when a sudden stand after relaxation or sitting, and is widespread among the elderly over the age of 65, and has several reasons:
- Drought and food shortages.
- Excessive fatigue.
- Excessive blood loss during menstruation.
- Central nervous system disorders.
- Cardiovascular disorders.
- Low blood pressure after eating: affects adults, mostly older people, and occurs as a result of the flow of a large amount of blood into the digestive system after eating.
- Structural hypotension: It is a permanent and chronic low pressure, without knowing the main cause of the disease.
Symptoms of low blood pressure
There are many symptoms of low pressure, some of which is not a hindrance to the activities of daily life, and what is only troublesome, namely:
- Feeling dizzy or fainting.
- Arrhythmia.
- Vomiting and fatigue.
- Feeling thirstier than usual.
- Misty vision.
- The coolness of the skin and its moisture.
- Weak focus and lack of attention.
the cure
The treatment of hypotension is characterized by several lifestyle changes and treatment of the main cause of the disease. These are some tips and treatments to avoid the damage caused by low pressure and control:
- Add more salt in your diet after reviewing and consulting your doctor.
- Get intravenous fluids.
- Change or stop taking medications that help lower blood pressure.
- Drink more water.
- Avoid caffeine.
- Drink appropriate amounts of useful juices.
- Exercise sports activities.
- Body posture changes quietly.
- Avoid tension and overload the body.
- Some medications, such as fluorocortisone, and medodrin, are prescribed only with a doctor.
- Sit and put the head between the knees, helping to restore blood pressure to normal.
