increased blood viscosity
Introduction
Introduction Blood viscosity is an important indicator of the nature of blood flow. Normal blood viscosity is an important condition to ensure blood circulation, especially the normal operation of microcirculation. Once the blood viscosity increases, the blood flow slows down, and a large amount of lipids, shed endothelial cells, etc. are easily deposited on the intima of the blood vessel, narrowing the blood vessels, slowing the blood flow, and relatively reducing the oxygen and nutrients obtained by the body. When the viscosity of the blood increases to a certain extent, blood coagulation occurs, that is, blood coagulation occurs, causing blood vessel embolism, thereby causing ischemic cardiovascular and cerebrovascular diseases.

Causes of increased blood viscosity
The main factors affecting blood viscosity are: red blood cell aggregation and deformability. In addition to red blood cells, there are many plasma proteins, such as globulin and fibrinogen. When these macromolecular proteins are increased, they often bind to red blood cells into a mesh, which increases the resistance of blood flow and leads to an increase in blood viscosity. Hematocrit, size and morphology, blood cholesterol, triglycerides and fibrinogen content.

Blood viscosity increase check
The blood viscosity increases and generally has the following early signals:
Dizziness in the morning and waking up at night. People with high blood viscosity feel dizzy after getting up in the morning, without the feeling of clear mind and smooth thinking. After eating breakfast, I gradually became awake. After dinner, the state of mind is the best.
Difficult after lunch. Healthy adults also have a feeling of drowsiness after lunch, but can be patient. People with high blood viscosity are trapped immediately after lunch and need to sleep for a while, otherwise they will feel unwell and will be listless all afternoon. If you sleep for a while, the mental state will obviously improve.
When you are working, you are short of breath. People with high blood viscosity are mostly obese, and these people have difficulty in squatting or shortness of breath when working. Because these people squat, the blood flowing to the heart and brain is reduced, and the blood is too thick, causing ischemia of vital organs such as the lungs and brain, resulting in difficulty in breathing.
Paroxysmal vision is blurred. In people with high blood viscosity, the blood cannot fully nourish the optic nerve, causing transient ischemia and hypoxia of the optic nerve and retina, leading to paroxysmal vision blur.

Symptoms of increased blood viscosity
Blood changes: changes in blood caused by various factors, such as increased blood viscosity, abnormal blood lipids. Abnormal rheological properties of the blood will cause blood circulation disorders in the body, especially blood viscosity is an important factor. High blood viscosity syndrome, clinically common is ischemic cerebrovascular disease, septic shock, diabetes, pulmonary heart disease. Coronary heart disease and so on. Low-viscosity syndrome, mainly characterized by lower blood viscosity than normal, the main cause of low-viscosity blood is red blood cell pressure reduction.
Hypoproteinemia: refers to the reduction of total plasma protein, especially plasma albumin. Mainly manifested as malnutrition. The proteins in the blood are mainly plasma proteins and hemoglobin contained in red blood cells. Plasma proteins include plasma albumin, various globulins, fibrinogen and a small amount of binding proteins such as glycoproteins, lipoproteins, etc., in a total amount of 6.5 to 7.8 g%. If the total plasma protein is less than 6.0 g%, it can be diagnosed as hypoproteinemia.
Calcium in the blood is too high: the normal value of blood calcium is 100 ml of calcium containing 9-11 mg of blood, which is 2.2-2.7 mmol per liter of blood. The normal fluctuation of blood calcium is small, mainly because calcium is extremely important for maintaining various physiological functions of the human body. The possibility of various diseases can be judged by the detection of blood calcium ions. For example, when the parathyroid gland is hyperactive, the blood ion calcium is higher than the normal range.
Increased blood viscosity: Blood viscosity is one of the factors that determine blood flow resistance. The viscosity of whole blood is 4-5 times that of water. Blood viscosity is an abbreviation for blood viscosity and is one of the indicators reflecting blood viscosity. The main factors affecting blood viscosity are: red blood cell aggregation and deformability, hematocrit, size and morphology, blood cholesterol, triglyceride and fibrinogen content.
Increased blood flow resistance: The resistance of blood flowing in blood vessels due to various reasons increases. Blood rheology tests can be diagnosed.
