Generally speaking, it is not recommended for diabetics to drink beer, even sugar-free beer. The main ingredient of beer is ethanol, which can inhibit hepatic gluconeogenesis and stimulate the body’s secretion of insulin, making it easy for hypoglycemia to occur. It can also further damage the pancreas, further destroying the function of the pancreas, which is not conducive to blood sugar control. Although the sugar content in sugar-free beer is low, sugar-free beer also contains alcohol, which can easily cause diabetic hypoglycemia symptoms in patients, which is not conducive to blood sugar control. If diabetic patients are combined with gout, drinking alcohol will also trigger gout attacks. In daily life, it is recommended that diabetic patients choose a low-sugar, low-salt, low-fat diet, with regular aerobic exercise, to control blood glucose in the normal range. At the same time, diabetic patients need to apply medication under the guidance of doctors.
