Is Red Wine Good to Bring Sugar Less than 160?

QUESTION: My blood sugar is 130–160 mg/dL two hours after meals and 95–106 mg/dL in the morning. Is red wine a good way to bring it below 160?





Quick Answer


No. Red wine should not be used to lower blood sugar. Your two-hour readings of 130–160 mg/dL are below the common target of 180 mg/dL for many adults already diagnosed with diabetes. Morning readings of 95–106 mg/dL range from normal to mildly elevated, depending on whether you have diabetes and whether they are laboratory or home-meter results. Alcohol can lower glucose unpredictably and may cause delayed hypoglycemia, especially with insulin or sulfonylureas.

Hi Sabet,



Your reported readings are generally reassuring, but red wine is not a diabetes treatment. A temporary fall after alcohol does not mean that glucose control has improved safely, and it does not reduce the need for appropriate food, activity, monitoring, or medicine.



How Should These Readings Be Interpreted?



If you already have diabetes, many nonpregnant adults use individualized targets of 80–130 mg/dL before meals and below 180 mg/dL one to two hours after a meal begins. On that basis, two-hour readings of 130–160 mg/dL are commonly within target, and morning readings of 95–106 mg/dL are also generally within the usual premeal target.



If you have not been diagnosed with diabetes, fasting laboratory glucose is interpreted differently:




  • Below 100 mg/dL: normal range

  • 100–125 mg/dL: prediabetes range

  • 126 mg/dL or higher: diabetes range when confirmed



A home reading after an ordinary meal cannot diagnose or exclude diabetes. Ask for an HbA1c and laboratory fasting glucose if your diagnosis is uncertain. See our guide to blood tests for diabetes.



Why Can Alcohol Lower Glucose?



The liver normally releases stored glucose between meals and overnight. While processing alcohol, the liver may become less able to release glucose. This can cause a delayed low several hours later, particularly when alcohol is consumed without food or combined with insulin or a sulfonylurea.



The risk may continue overnight. Symptoms of alcohol intoxication—such as confusion, sleepiness, slurred speech, or poor coordination—can also resemble hypoglycemia and delay treatment.



Can Red Wine Also Raise Glucose?



Yes. Sweet wine, larger portions, mixers, and food eaten with alcohol can add carbohydrate and calories. Excess alcohol can worsen triglycerides, blood pressure, sleep, medicine-taking, and overall glucose control. The effect can therefore be a rise, a fall, or little immediate change.



Do not use wine as a correction treatment for a glucose result. It is too unpredictable and may cause a dangerous low later.



Is Red Wine Good for the Heart?



People who do not drink alcohol should not begin drinking for heart or diabetes benefits. Older observational studies cannot prove that red wine itself protects the heart because diet, income, exercise, and other lifestyle factors may explain part of the association.



Heart protection is better supported through blood-pressure and cholesterol treatment, not smoking, regular activity, adequate sleep, and a Mediterranean-style eating pattern rich in vegetables, legumes, whole grains, fish, nuts, and suitable oils.



What If You Already Drink Alcohol?



Ask your clinician whether alcohol is safe with your medicines, liver and kidney function, triglycerides, blood pressure, and history of hypoglycemia. Alcohol may need to be avoided with pregnancy, pancreatitis, liver disease, alcohol-use disorder, severe neuropathy, frequent lows, or medicines that interact with it.



If your clinician says moderate drinking is acceptable:




  • Do not drink on an empty stomach.

  • Keep the portion small; one standard wine serving is about 5 fluid ounces or 150 mL.

  • Do not skip food or insulin to “make room” for alcohol.

  • Check glucose before drinking and later as advised, including at bedtime when low-glucose risk exists.

  • Carry glucose treatment and make sure companions know how to recognize hypoglycemia.



Current guidance advises no more than one drink daily for women and two for men, but less is safer and not drinking is also a healthy choice.



How Can You Improve After-Meal Glucose Safely?



Because your readings are already below 180 mg/dL, do not chase a lower number with alcohol or supplements. Review the carbohydrate portion, choose water instead of sugary drinks, include vegetables and protein, and consider a short walk after meals when medically safe.



Use a blood sugar log to compare consistently timed results and review our guide to blood sugar after eating. HbA1c is more useful than one after-meal number for assessing overall control.




Important Safety Note


Treat glucose below 70 mg/dL promptly according to your diabetes plan. Call emergency services for unconsciousness, seizure, inability to swallow, severe confusion, or a low that does not improve. Seek urgent care for persistent glucose around 300 mg/dL or higher with illness or dehydration, and emergency care for vomiting, difficult breathing, high ketones, glucose above 400 mg/dL, or a meter displaying “HI.”





Doctor’s Note


Your reported after-meal readings are generally within the common target for adults with diabetes. Red wine is not needed to lower them and may create delayed hypoglycemia. Confirm your diagnosis and overall control with HbA1c, and discuss alcohol specifically if you use insulin, glipizide, gliclazide, glyburide, or another medicine that can cause lows.
