Low Blood Diseases (Hypotension)

Low Blood Diseases (Hypotension)

Low blood disease or hypotension (hypotension) is a condition where a person's blood pressure dropped below the normal rate, reaching a low value of 90/60 mmHg. It has been described in previous articles (high blood diseases) that the normal value of a person's blood pressure with height, weight, level of normal activity and health in general is 120/80 mmHg.

However, some people may have a value of blood pressure (tension) in the range 110/90 mm Hg or 100/80 mm Hg, but they do not / have not or rarely reveal some significant complaints, so it is perceived in ordinary daily activities. If the condition continues, supported by several factors that enable trigger a significant decrease in blood pressure such as sweat and urinate a lot but less drinking, lack of sleep or less rest (tired of the excessive activity) as well as excessive menstrual bleeding (abnormal), then blood pressure will achieve low threshold (hypotension) 90/60 mmHg.

Signs and Symptoms of Low Blood Pressure

Someone who is experiencing low blood pressure generally will complain about the situation often dizziness, frequent yawning, sometimes perceived lack of clear vision (firefly), especially after a long sit and walk, cold sweat, feel tired no powerful, even experienced recurrent fainting.

On general examination beats / palpable pulse is weak, the patient was pale, this is due to the blood supply that is not the maximum tissue throughout the body.

Causes of Low Blood Diseases

There are several factors that cause why the decrease of blood pressure monitor, this can be categorized as follows:

- Lack of pumping blood from the heart. The more blood pumped from the heart each minute (cardiac output, cardiac output), the higher the blood pressure. Someone who has a disorder / heart disease resulting in abnormal heart rhythm, damage to or dysfunction of heart muscle, heart valve disease, the impact on lowering the blood pumping (cardiac output) throughout the organs.

- The volume (amount) of blood is reduced. This can be caused by severe bleeding (wound tear, excessive menstrual / abnormal), diarrhea that is not quickly resolved, excessive sweating, urination or excessive urination.

- The capacity of the blood vessels. Dilation of blood vessels (dilation) causes decreased blood pressure, this is usually as a result of septic shock, exposure by heat, diarrhea, drugs vasodilators (nitrates, calcium inhibitors, ACE inhibitors).

Handling and Treatment of Low Blood

There are several things you can do to improve the condition of lace blood pressure (hypotension), among others:

- Drinking water in considerable amounts of 8 to 10 glasses per day, an occasional cup of coffee to spur increased heartbeat so that the blood pressure will increase

- Eating foods that contain adequate levels of salt

- Exercise regularly such as walking in the morning for 30 minutes, at least 3x a week can help reduce the onset of symptoms

- In women who are encouraged to wear elastic stockings

- Provision of medicines (increasing blood) can only be done if symptoms of hypotension that felt really disrupt daily activities, other than that doctors will only provide vitamins (suport / placebo) as well as some suggestions that can be done for patients.

Regarding the image that most people think that eating goat meat for patients with hypotension may increase blood pressure monitor is actually not clear, however justified if it would increase the content of hemoglobin (Hb) in blood. Once again it must be understood that the low blood pressure means the blood supply was not optimal throughout the body. Haemoglobin (Hb) is low means that the content of Hb as an oxygen binding substances in the blood has low levels that consequently the patient may pale (anemia), dizziness (oxygen in the transport / blood supply to the brain less), feel tired and so forth.

In the case of hypotension that is really required the administration of drugs, usually there are several types of commonly used drugs such as fludrocortisone, midodrine, pyridostigmine, nonsteroidal anti-inflammatory drugs (NSAIDs), caffeine and erythropoietin.
