Diabetics Can Drink in Moderation, But Must Follow Key Principles to Avoid Hypoglycemia

Diabetic patients are often under the misconception that alcohol, being sugar-free, poses no risk to their blood glucose levels during social gatherings. However, a nutritionist from Dayeh Clinic warns that the real danger lies not in the immediate effects of drinking, but in the potential for "delayed hypoglycemia" hours later, which can lead to life-threatening shock.

Diabetic patients are not completely unable to drink alcohol, but they must achieve 'not drinking on an empty stomach, drinking in moderation, and frequent monitoring' to avoid 'delayed hypoglycemia'.

Nutritionist Chen Yi-ching explains that when the body is fasting or has consumed insufficient food, the liver initiates "gluconeogenesis" to produce glucose and maintain stable blood sugar. Alcohol, however, is treated as a toxin by the liver, causing it to halt gluconeogenesis and prioritize detoxification. This interruption, especially when combined with an empty stomach, insufficient meal intake, or the use of insulin or diabetes medication, can cause blood sugar levels to plummet rapidly.

When alcohol enters the body, the liver will treat alcohol as a 'toxin' that needs to be prioritized for metabolism, and will completely suspend the operation of gluconeogenesis, starting the 'all lines busy' detoxification mode.

The insidious nature of alcohol-induced hypoglycemia is that it often manifests hours after consumption, typically during sleep. Symptoms such as dizziness, cold sweats, palpitations, tremors, unsteadiness, slow reactions, confusion, and drowsiness can be mistaken for drunkenness, potentially delaying critical intervention. Chen stresses that these symptoms are nearly identical to those of severe intoxication, leading friends and family to overlook the signs of dangerously low blood sugar.

The low blood sugar caused by alcohol often does not occur at the time of drinking, but quietly appears in the middle of the night or early the next morning after returning home and going to sleep after a meal, hence it is called 'delayed hypoglycemia'.

To mitigate these risks, Chen advises diabetic individuals to strictly follow three principles if they cannot avoid drinking: never drink on an empty stomach, always consume alcohol with carbohydrate-containing foods like whole grains or rice, and increase the frequency of blood sugar monitoring, especially before bed. If blood sugar is low, consuming a few soda crackers or a small amount of juice before sleeping is recommended. She also advises limiting intake to one standard alcoholic drink for women and two for men per day. Consulting with a doctor or dietitian before altering drinking habits is also crucial.

Absolutely do not drink on an empty stomach; when drinking, pair it with carbohydrate-containing foods such as whole grains, sweet potatoes, white rice, or noodles to provide the body with sufficient glucose.
