Is low pressure 46 normal?

The blood pressure in our body is divided into high pressure and low pressure. Different places also call these two types of blood pressure high pressure and low pressure. Generally, low pressure is much lower than high pressure. The low pressure of a normal person is around 80. If the low pressure is too low, at 40 or 50, it means that the patient has symptoms of low blood pressure. At this time, the patient may often feel dizzy. So is a low pressure of 46 normal?

Abnormal, too low

1. Causes and hazards of low pressure and high voltage

1.1. Reasons for low pressure and high

1.1.1 Genetic diseases

Hereditary hypertension is common among middle-aged and elderly people. Middle-aged and elderly people are more susceptible to hypertension, and more than 40% of them have parents with a history of hypertension; if the parents do not have hypertension, the probability of their children suffering from hypertension is only 3%. More than 60% of the elderly suffer from obvious cardiovascular and cerebrovascular diseases, among which cardiovascular diseases caused by hypertension account for the vast majority.

1.1.2 Obesity

Overweight and obesity are important causes of susceptibility to hypertension. Obesity can not only cause high blood pressure, but also easily lead to many systemic diseases such as coronary heart disease, cholecystitis, arthritis, etc. Most obese people are sleepy and have a good appetite, which can easily form a vicious cycle.

1.2. Hazards of low pressure and high

Heart failure is a common complication of hypertension. Epidemiological studies have shown that 40% to 50% of heart failure is caused by hypertension. The higher the blood pressure, the greater the likelihood of developing heart failure without treatment. Hypertension has been considered to be the main risk factor for left ventricular hypertrophy and myocardial infarction, which can cause heart failure. Therefore, hypertension plays an important role in the course of heart failure.

2. What are the symptoms of low blood pressure?

Blood pressure is divided into high pressure and low pressure. Generally, in early-stage hypertensive patients, high and low pressure will not increase together. Usually, only one will increase. Generally, low blood pressure is in the normal range of 55-80, and high blood pressure is in the normal range of 85-125. Higher or lower than this value is an abnormal phenomenon. In the early stages of abnormal blood pressure, patients generally experience blurred vision, headaches, nosebleeds and other symptoms. These symptoms will disappear naturally after the patient takes medication to relieve them.

3. What inspections are needed for low pressure and high pressure

3.1. Blood routine examination

Hypertension accompanied by abnormal blood routine results may indicate the presence of secondary hypertension such as hyperthyroidism and polycythemia vera; it may also indicate that the hypertension is very serious and has caused renal failure, leading to renal anemia.

3.2 Urinalysis

Abnormal urine routine test indicates the possible existence of secondary hypertension caused by glomerulonephritis, chronic pyelonephritis, etc. If there is trace proteinuria in the urine, it indicates hypertension combined with early kidney damage. In addition to lowering blood pressure, the focus of treatment should be on improving renal function.
