Drinking wine will lower your glucose level — but not immediately. It takes about eight hours to see a lower blood sugar number from drinking dry white wine, according to a 2007 study in "Diabetes Care." All types of wine have 7 calories per gram and are easily converted to sugar in your body — dry white wine is no exception. For people with diabetes, drinking wine may cause hypoglycemia — very low glucose levels that can cause hunger, headache, fatigue, shakiness and mood swings. Drink alcohol in moderation and talk to your doctor about including wine in your diabetes management plan.
Glucose
Your body can use many things for fuel, but it’s preferred energy source is glucose. Glucose is most easily made from carbohydrates in the food you eat — especially sugar, because your body can digest simple carbs very quickly. Complex carbs such as fiber slow digestion and have less impact on blood sugar levels. When your body produces glucose, your pancreas releases insulin, a hormone that helps transport glucose into your cells for use. Glucose not needed immediately is then taken to your liver; some glucose is stored in your liver and some is converted into triglycerides — a type of fat — then moved into your fat cells.
Your Liver and Low Blood Sugar
When your body needs more energy, you may start to feel hungry or tired. Hormones signal your need for glucose, and your liver releases stored glucose into your bloodstream. This raises blood sugar until you eat again to provide fresh glucose. If your liver can’t release stored glucose, blood sugar may drop further, causing hypoglycemia — low blood sugar. Hypoglycemia can happen suddenly but usually does not require medical attention. Simply eating easily digested carbohydrates should raise blood sugar levels within 15 minutes, according to the National Diabetes Information Clearinghouse.
Alcohol and Your Liver
Your liver is an organ of elimination — a filter that helps remove toxins and unnecessary substances from your body. Alcohol is one of those substances. When you drink white wine, your liver tries to clear the alcohol from your body as quickly as possible, and stops its other functions, including releasing glucose. Your liver will not release glucose again until all the alcohol has been filtered from your bloodstream. That’s why drinking can lead to low blood sugar, especially morning low blood sugar after drinking at night — because you don’t eat overnight.
Conclusion
Lowering your fasting glucose level may not be a bad thing. Chronic high blood sugar can increase your risk of diabetes side effects such as nerve damage, blindness and kidney disease. A 2007 "Diabetes Care" study shows that Type 2 diabetics can lower A1C levels by drinking a moderate amount of wine with dinner. People with Type 1 diabetes may wake with hypoglycemia. Don’t drink on an empty stomach and don’t drink and exercise — physical activity can use too much energy and lower glucose levels too much.
