# Spring Health # Blood viscosity is called hyperviscosity in clinical medicine, which is more common in middle-aged and elderly people. Many people often generalize blood viscosity and hyperlipidemia, but they are not the same thing. Hyperlipidemia refers to high blood lipid level, and blood viscosity refers to high blood viscosity. Viscous blood (mainly caused by increased production components) is easy to produce embolus when it flows through some small blood vessels, and small thrombus develops into large thrombus, even causing serious vascular obstruction.

The degree of blood viscosity is influenced by many factors, such as diet, drinking water, exercise, metabolism and external environment, different seasons, time and climate. For a person, the degree of blood thickening is not eternal, but in a dynamic change from high to low.

People with thick blood may have special symptoms after four hours, so don't ignore them.

1, getting dizzy in the morning. Some people feel that their minds are not clear and their thinking is not smooth after getting up in the morning, but their spirits have reached a better state after eating, which is probably caused by high blood viscosity.

2. I am very sleepy after lunch. The drowsiness of healthy adults after lunch is tolerable; People with high blood viscosity are sleepy after lunch. If they don't have a rest, they will feel unwell and listless all afternoon. This is also because blood viscosity leads to insufficient blood supply to the brain. Only after a short lunch break will the mental state be significantly improved.

3, chest tightness when squatting. There are more obese people in the crowd with thick blood, and it is difficult for these people to squat down to do things, or they feel chest tightness and shortness of breath when they squat down. This is because when people squat, the blood flowing back to the heart will decrease. If the blood is too thick, it will make key organs such as lungs and brain ischemic, causing difficulty in breathing and holding your breath.

4, after work, the lips are purple, and it is easy to be short of breath. Some people have blue lips, and a little physical labor will cause diseases such as shortness of breath. This kind of people should not only be careful about blood viscosity, but also pay special attention to check whether they are accompanied by cardiovascular and pulmonary diseases.

Middle-aged and elderly people with the above symptoms and no clear history of cardiovascular and cerebrovascular diseases should see a doctor as soon as possible. Blood viscosity was monitored by hemorheology and platelet aggregation test.

In some cases, blood viscosity becomes high and there may be no symptoms. Hypertension patients, hyperlipidemia patients, long-term smokers (including second-hand smoke) and men over 45 years old are high-risk groups, so it is best to have regular physical examinations.
