Low blood pressure just dizziness? Doctor: There are 2 types of hypotension with different symptoms!
Presumably everyone should have heard of the "hypertension" disease, which refers to the patient's arterial blood pressure exceeding the normal range.
It seems to be just a problem of elevated blood pressure, but there are many complications behind it. Long-term excessive blood pressure can cause damage to many organs and tissues such as the heart, brain, blood circulatory system, and kidneys. It is cardiovascular disease. risk factors.
It is precisely because high blood pressure is very scary that everyone focuses on increasing blood pressure, thinking that the lower the blood pressure, the healthier it is.
As everyone knows, there is precisely one kind of blood pressure change in clinical practice, which is called " hypotension ", which refers to the state where the systemic arterial pressure is lower than normal.
Due to the huge harm of hypertension, the WHO also clearly stipulates the diagnostic criteria for hypertension, that is, the patient's arterial systolic blood pressure exceeds 140 mmhg and the diastolic blood pressure exceeds 90 mmhg . However, there is still no unified standard for the diagnosis of hypotension in the world.
Judging from the current clinical data, a healthy adult should have normal blood pressure below 120 mmhg for systolic blood pressure and below 80 mmhg for diastolic blood pressure . The normal high value of blood pressure fluctuates in the range of 120/139~80/89mmhg . If an adult's upper extremity arterial blood pressure is less than 90/60 mmhg , it can be counted as hypotensive.
According to the etiology of low blood pressure, it can be divided into two types:
1. Physiological
The so-called physiological hypotension refers to the fact that some healthy people have reached the standard of hypotension when they go to the doctor for examination, but the patient does not have any conscious symptoms.
After a long-term follow-up investigation, it was found that in addition to low blood pressure, there were no symptoms of ischemia and oxygen in various organs of his body, and it did not affect his life expectancy. This situation usually occurs in the elderly and women who are thin and weak . It can be said to be physiological hypotension or primary hypotension;
2. Pathological
Pathological hypotension is not difficult to understand, it means that in addition to lower blood pressure, the body is also accompanied by different symptoms and certain diseases.
It is important to mention here that low blood pressure caused by some diseases, such as acute myocardial infarction, massive bleeding, severe physical trauma, infectious diseases or allergies, etc. , will lead to a rapid drop in blood pressure.
However, in most cases, hypotension occurs slowly, and it can gradually worsen as the disease progresses, such as hypotension secondary to severe tuberculosis, cancer, malnutrition, and cachexia . This kind of hypotension can be regarded as pathological hypotension or secondary hypotension.
There are various clinical manifestations of hypotension. The most common symptoms are that patients are prone to mental fatigue, frequent dizziness and headache, and in the case of a rapid drop in blood pressure, dizziness, weakness of limbs, cold sweats, and even sudden syncope occur. and other symptoms. The severity of its symptoms is mainly related to the patient's pathogenic factors, age, and physical condition.
If you measure your blood pressure at home and find that your blood pressure is too low, you have met the diagnostic criteria for hypotension. In this case, you should seek medical attention in time for relevant examinations to see if it is related to the appearance of the disease and causing hypotension.
In particular, patients with known comorbidities should communicate with their doctors in time to see if they need treatment for hypotension. After excluding disease factors, the patient can make relevant adjustments according to the doctor's advice, so that the blood pressure gradually returns to normal.
