How does drinking alcohol affect my blood sugar, and is it safe to drink?

Alcohol has a very complex relationship with blood sugar and can actually cause it to either spike or drop unpredictably depending on what you drink and what medications you take. Sugary mixed drinks, sweet wines, and heavy craft beers are high in carbohydrates and will initially cause a rapid blood sugar spike. However, the alcohol itself prevents your liver from releasing its normal baseline of stored glucose. This means that hours after drinking, especially if you are on insulin or sulfonylureas, you are at a significantly higher risk for delayed hypoglycemia (dangerously low blood sugar), often while sleeping. If you choose to drink, moderation is key: stick to dry wines, light beers, or spirits mixed with zero-calorie sodas. Most importantly, never drink on an empty stomach; always consume alcohol alongside a meal or a solid snack containing complex carbs and protein to keep your numbers stable overnight.
