Thickening of blood lipids is considered to be high blood fat, which may lead to cerebral blood clots. High blood lipids generally refer to high levels of cholesterol and/or triglycerides in the blood. It may be related to excessive fat intake, abnormalities in lipoprotein synthesis and metabolic processes. When lipids in the blood are deposited in the lining of blood vessels, it may lead to atherosclerosis. Cerebral thrombosis is a pathological change in brain tissue caused by ischemia, hypoxia, and necrosis due to the thickening of blood vessel walls and narrowing and occlusion of the lumen caused by cerebral atherosclerosis, which results in reduced or interrupted blood flow. Symptoms such as numbness and weakness of the upper and lower limbs on the same side of the body, slanting of the eyes and mouth, and slurred speech may occur. When the blood fat is elevated for a long time, the lipid deposition in the cerebral artery and lead to cerebral atherosclerosis may induce the occurrence of cerebral thrombosis, so high blood fat may lead to cerebral thrombosis. Thickening of blood fat is recommended to consult a doctor in time to clarify the cause of the disease with the help of a doctor, and to carry out targeted treatment or therapy.
