Patients with thick blood may experience drowsiness, weakness, dizziness, precordial discomfort, and in some cases, tingling of the limbs. In patients with this condition, it is important to further identify the cause. In addition, it is important to combine this with aggressive treatment to clarify whether there is currently a more severe elevation in blood lipids. If dyslipidemia exists, the first thing to do is to take relevant oral lipid-lowering drugs. For patients with cardiovascular disease, in addition to lipid-lowering and plaque-stabilizing drugs, antiplatelet therapy should be combined to prevent the occurrence and development of atherosclerosis. Patients are advised to take oral medications such as bai aspirin, clopidogrel, as well as atorvastatin and resulvastatin. In addition, patients are advised to further examine the causes of thick blood, such as whether it is due to nephrotic syndrome, hypothyroidism, or high-fat diet. It is necessary to pay attention to a low-salt and low-fat diet, quit smoking and drinking, regular work and rest, and eat more fresh fruits and vegetables in order to improve the thickening of blood.
