It is not recommended for people with high blood sugar to drink alcohol. Patients with high blood sugar will have insulin resistance or decreased insulin secretion, and drinking alcohol in a fasting state or after taking hypoglycemic drugs may lead to hypoglycemia. If you drink alcohol with sugary foods or sugary drinks, it may also raise blood sugar and cause other metabolic diseases in serious cases.1. Cause hypoglycemia: If hyperglycemic people drink alcohol in a fasting state, the ethanol in alcohol can inhibit the hepatic glycogen isogenesis, leading to a drop in blood sugar. At the same time, during the process of drinking, ethanol stimulates the secretion of insulin, and too much insulin is secreted, which will also lead to a drop in blood sugar. 2. cause elevated blood sugar: in the process of drinking for hyperglycemic people, some alcohols contain higher sugar, such as beer, sweet yellow wine, sweet wine, etc., which will cause elevated blood sugar. Secondly, if patients drink alcohol after taking hypoglycemic drugs, the ethanol in alcohol degrades the drug’s efficacy, making it impossible for hypoglycemic drugs to work best, raising blood sugar; 3, other hazards: hyperglycemia is usually accompanied by a certain degree of metabolic disorders, drinking is prone to hyperlipidemia, hyperuricemia, etc., which in severe cases may cause fatty liver, heart, kidney and other dysfunctions, and also easily stimulate the stomach and intestines, and gastroduodenal inflammation occurs. The inflammation of the gastroduodenum occurs, etc. Therefore, it is not recommended that patients with high blood sugar drink alcohol, including white wine, red wine, beer, yellow wine, try not to drink. If you must drink, you should pay attention to the right amount and avoid drinking on an empty stomach. Patients with elevated blood sugar should develop good habits, quit smoking and drinking, control their diet and exercise properly.
