Reduction of Blood pressure
Blood pressure is low when it is less than 90/60 mmHg, and blood pressure is usually expressed in two readings: the first and the highest measures systolic pressure, ie, blood pressure in the arteries at the moment of contraction of the heart muscle and filling with blood, while the second and minor readings measure diastolic pressure, The heart muscle is between the pulses. The normal reading of blood pressure is less than 120/80 mmHg in healthy subjects.
Non-symptomatic low blood pressure is not important and does not usually require treatment, but sometimes it may indicate a health problem, especially in older people. It may lead to a lack of vital organs, such as the heart and brain, of blood and oxygen. This may lead to dizziness or dizziness.
There are several types of hypotension, the most common is the so-called low blood pressure, which occurs suddenly when standing after lying or sitting for a long time; as the blood collects when standing in the lower limbs, and arises because of the failure of the circulatory system and the nervous system in the body Respond appropriately to these sudden changes, and then sends the human body signals the heart to increase the pulse, and blood vessels to contract, to resist this decline.
There is another type called nervous hypertension, which happens when standing for long periods of time, and increases the chance of falling blood pressure as the age increases, as a result of changes in the human body, as about 10 to 20% of people over the age of sixty-five suffer low Positive blood pressure.
Causes of low blood pressure
Low blood pressure has many causes; in some cases it is a sign of good health and activity, as it may be inherited in the family. Stress readings may vary by day, depending on mood, temperature, and diet. All of these should be taken into consideration when measuring blood pressure. If low blood pressure persists, it may be due to several conditions:
- Pregnancy: The blood pressure of pregnant women is usually low, due to the rapid expansion of blood circulation, and this is normal during pregnancy, and usually return blood pressure to normal after birth.
- Heart disease: Some heart diseases may lead to low blood pressure, such as severe heart failure, heart valve diseases, angina, and heart failure. These diseases cause low blood volume in the arteries, which is reflected in blood pressure .
- Endocrine diseases such as thyroid disease, thyroid glands, adrenal insufficiency, Addison disease, low blood sugar, and diabetes may sometimes trigger hypotension.
- Drought: This condition occurs when body fluids are lost, resulting from high body temperature, vomiting, diarrhea, excessive use of diuretics and stress. A serious complication of dehydration is the so-called hypotension, which causes low blood pressure, thus reducing the amount of blood and oxygen reaching the various tissues of the body. If left untreated, it can lead to death within minutes or hours.
- Bleeding: Blood loss due to either a major wound, internal bleeding or major surgery leads to sudden drop in blood pressure.
- Suffering from severe infection or septicemia; this causes another type of trauma called septic shock.
- Severe allergic reaction: It is a serious condition that results from either eating some medicines or foods or from insect or snake venom. It causes breathing problems, skin rash, severe itching, and low blood pressure.
- Some types of drugs such as:
- Diuretics: such as furozemide and hydrochlorothiazide.
- Alpha receptor inhibitor drugs: such as prazosin and lactalol.
- Beta-receptor inhibitors: such as atenolol and propranolol.
- Medications used to treat Parkinson’s disease: such as Premipicol and those containing levidopa.
- Some antidepressant drugs: such as doxypine, and imibramine.
- Anemia: Usually results from eating foods lacking vitamin B12 or folic acid.
Symptoms of low blood pressure
Hypertension is not associated with any symptoms, especially if the patient is not suffering from any disease. The symptoms that may be caused by low blood pressure depend heavily on the member whose blood supply has decreased, including feeling dizziness and dizziness, in addition to general weakness and fatigue As well as shortness of breath, palpitations, accelerated heart rate, blurred vision, lack of concentration, in addition to feeling thirsty and nausea, and may also cause the skin to cool and pale color.
Treatment of low blood pressure
It is necessary to treat blood pressure only if there are some symptoms; it does not usually need any treatment, and the treatment to take general measures and the treatment of some drugs in addition to the treatment of the underlying cause. The treatment of low blood pressure is as follows:
- Follow general measures to reduce symptoms associated with the most common types of hypotension, including:
- Stopping gradually: especially when waking up in the morning, and is usually advised to exercise physical movements before standing, such as stretching, to increase the activity of the heart, and the flow of blood in the organs of the body.
- Avoid standing for long periods of time: this is to prevent the occurrence of hypotension.
- Wear long socks: Also called compression socks: increasing pressure on the feet and abdomen, which improves blood circulation and raises blood pressure, and consult your doctor before resorting to this method is not suitable for everyone.
- Avoid caffeine-containing beverages at night, as well as non-alcoholic beverages: to prevent dehydration, which may lead to low blood pressure.
- Eat small, frequent meals, and lying down or sitting down after eating can help prevent low blood pressure.
- Increased intake of fluids and salts: This helps to avoid the condition of drought, which is one of the common causes of low blood pressure.
- Change of medicines: If the patient is taking drugs that reduce blood pressure, then the doctor may change those drugs with other drugs.
- Some medications may be used to treat some types of medications used to treat hypotension, if the above methods fail. These drugs include fluorocortisone, which increases the blood volume and raises the pressure. Medodrin, which reduces the ability of blood vessels On the stretch.
