Alcohol consumption is not recommended during insulin injection as it may cause hypoglycemia. Insulin can lower blood sugar and is indicated for type 1 diabetes, type 2 diabetes where oral hypoglycemic drugs are ineffective, and diabetes combined with acute metabolic disorders. Side effects of insulin include hypoglycemia, pain at the injection site, redness, hives, etc. It is contraindicated in patients who are allergic to insulin. Drinking alcohol during insulin injection is not recommended because alcohol can inhibit hepatic glycogenolysis and stimulate insulin secretion, which can easily lead to hypoglycemia, and excessive alcohol consumption has a depressing effect on the central nervous system, which can mask hypoglycemia symptoms and cause danger. People with diabetes need to pay attention to eating healthy, and for more dietary advice you can consult your doctor.
