Hypoglycemia from Alcohol: What You Need to Know About Blood Sugar Drops

When you drink alcohol, your liver stops doing its main job—releasing glucose into your blood—to focus on breaking down the alcohol instead. This can cause hypoglycemia from alcohol, a dangerous drop in blood sugar levels triggered by alcohol consumption, especially if you haven’t eaten or if you’re taking insulin or other diabetes meds. It’s not just a problem for people with diabetes; even those without it can experience symptoms like shaking, sweating, confusion, or fainting after heavy drinking on an empty stomach.
