Lipids are usually tested using a venous blood draw for cholesterol, triglycerides, LDL, HDL, and very low density lipoprotein. Cerebral Blood Supply Insufficiency refers to the lack of blood in the brain due to spasm of blood vessels in the brain or arteriosclerosis, which results in clinical manifestations such as dizziness, headache, and unsteady walking. Cerebral blood supply insufficiency occurs in high blood fat, high uric acid, high blood pressure, etc. It is also prone to occur in the change of seasons due to the big difference in temperature, which causes vascular spasm and leads to cerebral blood supply insufficiency. Go to a regular hospital to have blood drawn from a vein, and eat a normal diet 2 to 3 days before the lipid test, do not consume too much fatty food or eat too much, as these will affect the composition of the blood. After the results are obtained, the doctor will make a diagnosis of the results and actively treat the original disease. If there is high blood pressure, the blood pressure and weight should be strictly controlled and regular checkups should be conducted in the hospital. If you feel unwell, you should consult a doctor in time, and follow the doctor’s professional guidance and treatment in accordance with the doctor’s instructions.
