Patients with thrombosis should not drink alcohol because it may lead to hypercoagulability, which affects the blood clotting function and may trigger thrombosis after drinking. If you drink a lot of alcohol and get drunk, the patient will stay still for a long time, which will cause the blood to stagnate and may also trigger thrombosis. In addition, when drinking alcohol, the blood pressure of the human body will be transiently increased, which will damage the lining of the blood vessels, resulting in damage to the lining, platelet aggregation and fibrinogen aggregation on the basis of atherosclerosis, which will lead to thrombosis, so patients with thrombosis should not drink alcohol.
