Can I drink alcohol in moderation when my diabetes is well-controlled?

Generally speaking, people with well-controlled diabetes can consume alcohol, but it should be done in moderation. The detailed explanation is as follows:

Before drinking alcohol, it is necessary to ensure that blood glucose levels are stable within a certain range and that glycated hemoglobin (HbA1c) is below 7%. This is the prerequisite for alcohol consumption, as significant fluctuations in blood glucose may worsen the condition. Low-alcohol beverages such as dry red or dry white wine are preferable, while high-proof spirits or sweet wines containing large amounts of sugar should be avoided. Strong alcoholic drinks may cause greater physical stress and easily lead to blood glucose fluctuations, while the sugar in sweet wines can rapidly elevate blood glucose levels.

Men should not consume more than 25 grams of alcohol per day, and women should not exceed 15 grams. Excessive alcohol consumption can harm the body and may lead to loss of blood glucose control. Additionally, drinking on an empty stomach should be avoided. Instead, one may first eat some staple foods or protein-rich foods, such as bread, eggs, or milk. This can delay alcohol absorption and reduce the risk of hypoglycemia.

After drinking, closely monitor blood glucose changes, especially during the first few hours following alcohol consumption. If symptoms of hypoglycemia occur, such as dizziness, fatigue, or sweating, it is important to promptly consume some candy or biscuits to quickly raise blood glucose levels.
