Thus, hyperinsulinemia refers to higher than normal insulin levels in the blood, whereas hypoglycemia refers to lower than normal glucose levels in the blood. This is because the liver has to work to remove the alcohol from the blood instead of managing blood sugar levels. Alcohol consumption can also lead to situational unawareness of low blood sugar levels. Normal fasting blood sugar levels should be in the range of 70–100 milligrams per deciliter (mg/dl).
Mitigating the Risks of Drinking Alcohol for People With Diabetes
Significant increases in HDL could be observed in healthy men as early as 17 days after initiation of 40 g/day of alcohol (30). Alternatively, it is possible that the HDL-elevating effect of alcohol is less readily detectable among diabetic subjects, particularly when they are also treated with glucose- and lipid-lowering medications. This notion is supported by observations made during a previously mentioned trial among diabetic subjects after a myocardial infarction, in which a significant increase in HDL was observed only after 9 months of alcohol intake (R. Marfella, personal communication).
The Immediate Effect of Alcohol in People With Diabetes
Additionally, 1–3 weeks of moderate alcohol consumption in humans did not alter the basal insulin concentration [61,87] and plasma insulin did not differ after long-term moderate alcohol intake [96]. The relationship between the magnitude of alcohol consumption and basal insulin concentrations may also be J- or U-shaped. For example, mild to moderate alcohol consumption in humans has been repeated demonstrated to decrease fasting insulin levels relatively to subjects consuming no/low alcohol and/or those with a high alcohol intake [22,23,24,109,110].

- In contrast to the ability of insulin to increase glucose uptake in striated muscle and fat (see following sections), insulin normally inhibits hepatic glucose production (HGP).
- Direct evidence for the suppression of muscle IMGU by acute alcohol was also reported in humans using the A-V difference method [52].
- The IGI was calculated as (insulin 60min − insulin 0min)/(glucose 60min − glucose 0min)10,11.
We use only trustworthy sources, including peer-reviewed studies, board-certified medical experts, patients with lived experience, and information from top institutions. Drugs in the GLP-1 family, including semaglutide and tirzepatide, are known to provoke vomiting — just like excessive drinking. Many spirits (vodka, tequila, and so on) have only trace amounts of carbohydrates; a glass of wine probably has only a few grams of carbs. A can of light beer may have only a handful of grams of carbohydrates; a regular beer about a dozen. Moderate alcohol consumption, therefore, does not need to result in large carb counts. The Diabetes Link, a nonprofit dedicated to helping teens and young adults with type 1 diabetes, maintains a resource page with advice on how to navigate drinking and diabetes.
Night owls vs. early birds: Study reveals who has better cognitive function
Although based on a minority of studies, there is also the possibility that reductions in risk may have been overestimated by studies using a referent group contaminated by less healthy former drinkers. Observational studies indicate that moderate levels of alcohol consumption may reduce the risk of type 2 diabetes. In addition to providing an updated summary of the existing literature, this meta-analysis explored whether reductions in risk may be the product of misclassification bias. Kaplan-Meier curves for the incidence of diabetes according to the combined model of genetic variants ((A) GCK or (B) INSR) and chronic heavy alcohol consumption.
- P-values were calculated by Cox proportional hazard analysis with adjustment for age, physical activity, family history of diabetes, smoking status, and BMI.
- For example, in experimental conditions where acute alcohol produced hypoglycemia (i.e., prolonged fast), there is a consistent and profound decrease in glucose Ra accompanied by an inappropriately elevated rate of glucose Rd [17,19,20].
- Elevated levels of those compounds can cause nausea, vomiting, impaired mental functioning, coma, and even death.
- As mentioned earlier, ethanol metabolism by CYP2E1 and NADH oxidation by the electron transport chain generate ROS that results in lipid peroxidation.
In contrast, T2DM (non-insulin dependent diabetes) continue to produce insulin in the early phase of the disease; however, the body resists insulin’s effect. A deficit in insulin secretion, coupled with the state of insulin resistance, leads to T2DM [20]. Therefore, T1DM is characterized by a complete lack of insulin production, whereas, T2DM is characterized by a reduction of insulin production plus resistance [21]. Unlike T1DM, where insulin therapy can provide effective relief, T2DM requires treatment of insulin resistance, in addition to insulin secretion defects. Ketoacidosis, which occurs primarily in diabetics, is a condition characterized by excessive levels of certain acids called ketone bodies (e.g., acetone, acetoacetate, and β-hydroxybutyrate) in the blood.
- For people with diabetes, drinking alcohol can cause low or high blood sugar, affect diabetes medicines, and cause other possible problems.
- This article discusses how alcohol can impact diabetes and related conditions and offers tips for safe drinking.
- Extracted data included sample size, country, baseline age, sex, confounder adjustment, length of follow-up, and risk estimates for each exposure category.
- More detailed data might be obtained through the use of methods such as the glucose clamp technique.
- Using a similar model of acute alcohol administration, Spolarics et al. [12] also reported reduced glucose uptake in some muscles (e.g., red quadriceps and soleus), but not others (e.g., gastrocnemius and white quadriceps).
The ethanol concentrations peaked 120 min after loading during both the OGATT and OATT (0.14 ± 0.07 and 0.24 ± 0.16 mg/dL, respectively). The ethanol concentration was significantly lower during the OGATT than during the OATT 15, 30, 60 and 120 min after a 20‐g ethanol load (Table 4). Hypoglycemia occurred more frequently can diabetics get drunk after the simultaneous consumption of alcohol plus glucose than after the consumption of glucose alone, suggesting that alcohol in the combination of glucose induces reactive hypoglycemia.
