Hyperviscosity needs to be treated. This is because hyperviscosity leads to increased blood viscosity, increased circulatory resistance, and a higher risk of cardiovascular disease. Hyperviscosity is a condition in which the blood is excessively thick and slow, and is usually diagnosed by a blood flow test. After diagnosis, it can be treated by drinking more water, proper diet, moderate exercise and medication under the guidance of a doctor. 1. Drinking plenty of water: It can reduce the blood viscosity to a certain extent. 2. Reasonable diet: It is recommended to eat light food. Don’t eat too much greasy food, animal offal, fat, etc. 3. 3. Moderate exercise: It can promote blood circulation, which can improve hyperviscosity to a certain extent. 4. Medication: Under the guidance of doctors, anticoagulant drugs such as aspirin enteric-coated tablets, warfarin, atorvastatin and dipyridamole and lipid-lowering drugs can be used for medication. Patients with hyperviscosity should go to the internal medicine department of the hospital and take reasonable treatment plan under the guidance of doctors to reduce the chance of cardiovascular and cerebrovascular diseases.
