Alcohol and diabetes: Effects, blood sugar levels, and guidelines

The findings discussed here presents that the role of chronic use of alcohol on diabetes might be high of importance for clinical research and practice. The finding that was shown may also help to explain previous contradictory findings, regarding the association between alcoholism and diabetes. Chronic heavy consumption deteriorates glucose tolerance and insulin resistance, and this may well be one of the mechanisms involved in the malignant effect of alcohol, with regard to development of diabetes. The novel mechanisms of these two appetite regulating peptides, BDNF and hippocampal LTP are widely involved in the neurobiology of alcohol dependence and T2DM. It deserves to be investigated more intensively in diabetogenic effects of chronic alcohol consumption. Therefore, understanding of the pathophysiological bases of these mechanisms should enhance better approaches to a potent therapeutic strategy for the treatment of both alcoholism and diabetes.



However, it does not mean people with type 2 diabetes cannot drink alcohol. The risks depend on how much alcohol a person consumes, as well as the type. Each alcoholic beverage takes about 1-1 ½ hours to finish processing in the liver. So, if you have 2 drinks, you double that time to 2 to 3 hours that you are at risk for low blood sugar. The more alcohol consumed, the bigger the risk for serious low blood sugar. In conclusion, while it’s possible to enjoy alcohol in moderation with diabetes, you must be aware of the potential dangers and take steps to minimize risks.


Things to Keep in Mind If You Choose to Drink


The main function of your liver is to store glycogen, which is the stored form of glucose, so that you will have a source of glucose when you haven’t eaten. When you drink alcohol, your liver has to work to remove it from your blood instead of working to regulate blood sugar, or blood glucose. For this reason, you should never drink alcohol when your blood glucose is already low. If you drink, do it occasionally and only when your diabetes and blood sugar level are well-controlled.



Drinking less—as any healthcare professional will tell you—is better. According to the American Heart Association, red wine contains antioxidants, which are compounds in certain foods that help prevent cell damage. Most importantly, if individuals wish to engage in moderate drinking, they should first discuss it with their doctor.


What are the recommended alcohol guidelines for people with diabetes?


The risk of hypoglycemia is why experts advise people with diabetes not to drink alcohol if their blood sugar is already low. If a person chooses to drink, they should always eat at the same time and include carbohydrates, such as fruits, vegetables, or grains, in their meal. Keep reading to learn more about how alcohol affects people with diabetes, including types of alcohol https://ecosoberhouse.com/ and how alcohol may cause hypoglycemia, or low blood sugar levels. Normally, the liver releases glucose to maintain blood sugar levels. But when you drink alcohol, the liver is busy breaking the alcohol down, so it does a poor job of releasing glucose into the bloodstream. This can lead to a drop in blood sugar levels if you are drinking alcohol on an empty stomach.



Since it doesn’t contain juices or other mixers, it contains 0.2 grams of total carbs in a 4-ounce (120-mL) drink. This makes it a good choice for people with diabetes — provided you drink it in moderation (25). Aside from having a low carb content, red wine may lower the risk of diabetes-related complications if consumed in moderation. White wines, especially some types of Champagne, also generally have a low carb count. Studies show that drinking it may improve heart disease markers and reduce the risk of diabetes-related complications such as diabetic retinopathy, which damages blood vessels in the eyes (16, 20).


Heart-Healthy Benefits of Alcohol


Diabetics clearly should avoid heavy drinking (i.e., more than 10 to 12 drinks per day), because it can cause ketoacidosis and hypertriglyceridemia. Moreover, heavy drinking in a fasting state can cause hypoglycemia and ultimately increase diabetics’ risk of death from noncardiovascular causes. Abnormalities in the levels and metabolism of lipids diabetes and alcohol are extremely common in people with either type 1 or type 2 diabetes and may contribute to those patients’ risk of developing cardiovascular disease (Durrington 1995). Alcohol consumption can exacerbate the diabetes-related lipid abnormalities, because numerous studies have shown that heavy drinking can alter lipid levels even in nondiabetics.


  • Despite a clear indication for confirmatory toxicology monitoring, a standardized battery of abstinence biomarkers is not universally used in clinical practice.
  • People often think of this as a “healthy” cocktail due to its vegetable content.
  • While a lot of alcoholic drinks contain carbs, you might not need to take your usual mealtime amount of insulin to cover them.
  • Beverages such as beer and wine can have an alcohol content of 2–20%.

In contrast, Malik et al. proposed a more comprehensive protocol of the carbohydrate challenge test with serial ethanol monitoring up to 24 h after oral ingestion of 200-g glucose. These authors also proposed conducting upper and lower endoscopies to harvest gastrointestinal secretions for microbiological study [27]. These comprehensive diagnostic tests and procedures will enable the clinical team to diagnose a GFS case confidently. However, the apparent under-recognition and poor acceptance of GFS among the medical community and uncertain health insurance coverage of these tests may deter clinicians from using these comprehensive diagnostic tests at once [69]. If we contrast GFS with BFS, one of the key differences is the clinical manifestation of alcohol toxicity, as discussed earlier.
