Study uncovers alcohol’s damaging effects on brain cells through oxidative stress

Dose-response relationship between average daily alcohol consumption and incident type 2 diabetes. Finally, factors potentially contributing to any observed heterogeneity were investigated. These were thought to include participant age, method of case ascertainment, degree and type of confounder adjustment, follow-up duration, the healthy worker effect (32), and population region (33).

Alcohol’s Effects on Blood Sugar Levels of Diabetics

A daily cocktail or two may improve blood glucose (blood sugar) management and insulin sensitivity. If you have one or more drinks a day, you may find that your A1C is lower than during times you weren’t drinking. After all, other aspects of moderate drinkers’ lives may be behind the link. As noted above, the studies on glucose tolerance and insulin resistance in alcoholism focused on the impact of chronic heavy use of alcohol on the development of T2DM. Accordingly, deterioration in glucose homeostasis and insulin secretion in alcohol dependence may not only represent a consequence of T2DM, but also plays an important role in its cause, as well as its treatment.

Are there benefits to drinking alcohol with diabetes?

The assumption of stable temporal consumption is likely to be invalid, with disparate trajectories of alcohol consumption consistently identified regardless of the length of follow-up or the age of the cohort under study (64,65). Dose-response relationship between average daily alcohol consumption and incident type 2 diabetes, stratified by referent category and adjusted for sex. The problem is that the liver cannot perform both functions at the same time.

Can I Drink Alcohol If I Have Type 2 Diabetes?

Many existing alcohol-diabetes studies may have therefore overestimated the degree of risk reduction among moderate consumers of alcohol by comparing drinkers to a less healthy nondrinking referent category (17). Indeed, in a meta-analysis exploring the relationship between alcohol consumption and all-cause mortality, reductions in risk were attenuated when data were restricted to studies that excluded former drinkers from the referent category (18). Data from the standard glucose tolerance test provides information on glucose tolerance, but is a poor predictor of insulin action/resistance especially in the absence of accompanying insulin levels [114].

  1. Most importantly, insulin leads to the uptake of the sugar glucose into muscle and fat tissue and prevents glucose release from the liver, thereby lowering blood sugar levels (e.g., after a meal) (see figure).
  2. Because of the effects alcohol can have on blood sugar control and other aspects of the disease, you face certain risks by drinking alcohol if you have type 2 diabetes that otherwise healthy people may not.
  3. If you have a number of these drinks, you can expect to see a rise in blood sugar followed by a steady drop a number of hours later, often whilst asleep.
  4. The risk of hypoglycemia is why experts advise people with diabetes not to drink alcohol if their blood sugar is already low.
  5. For studies for which various estimates including more or less covariates were reported, and a choice existed as to which to include, those that controlled for the most potential confounders not on the causal pathway were chosen.


Among all types of wine, red wine is linked with the most health benefits — both for people with diabetes and for the general population — due to its high antioxidant content (17, 18, 19). Busch beers are good alternatives for people with diabetes due to the low carb content of most of the brand’s products — including their beers that are not branded as low carb. Drinking liquid marijuana alcohol carries the same health risks for people with diabetes as it does in otherwise healthy people. But there are certain risks related to having diabetes that are important to know. People with diabetes have to be very careful when it comes to drinking alcohol. It is a good idea for them to talk with a doctor so that they thoroughly understand the risks involved.

Thus, studies have also determined whether alcohol might alter glucose uptake in a tissue-specific manner. As a metabolically active tissue representing 40%–45% of total body weight, skeletal muscle has been the focus of many of these studies. For example, Molina et al. [51] used an in vivo injection of 14C-radiolabeled 2-deoxyglucose (2DG) to trace regional glucose uptake in rats during a 4 h continuous infusion of alcohol that did not alter basal glucose or insulin concentrations.

Alcohol also dose-dependently inhibits lactate-stimulated gluconeogenesis when given acutely in the in situ perfused liver [32] and when added to isolated hepatocytes [33]. Collectively, these data are consistent with those from in vivo studies showing acute alcohol decreases whole-body estimates of glucose recycling (e.g., glucose → lactate → glucose) and lactate turnover [27]. Exercise can also increase the risk of hypoglycemia when coupled with other factors, after the high the dea such as drinking alcohol. Doctors strongly encourage people with diabetes to engage in regular physical activity because it reduces blood sugar. However, exercising, drinking alcohol, and taking blood sugar-lowering medication could cause hypoglycemia. Although the gold standard in diabetes ascertainment is the OGTT, the individual studies ascertained diabetes status in various ways including self-report, linkage with national registries, and clinical tests.

DM is a syndrome of disordered metabolism with abnormally high blood glucose levels, as a result of abnormal insulin secretion and/or signaling (hyperglycemia) [17]. Hypoglycemia shows abnormally low levels of glucose in the blood, which interfere with the function of organ system. The two most common forms of DM are type 1 (T1DM) and type 2 diabetes, with T1DM accounting for approximately 10% of all cases in Caucasians [18]. Glycogen is a large molecule that consists of numerous glucose molecules and serves as a storage form of glucose in the tissues, particularly the liver. In the fasting state, as a first line of defense against hypoglycemia, glycogen is broken down into its constituent glucose molecules, which are secreted by the liver into the blood to maintain normal or near-normal blood sugar levels. Generally, the glycogen supply is depleted after 1 or 2 days of fasting.

Skeletal muscle represents the largest body depot responsible for IMGU [130,131]. Therefore, an acute alcohol-induced decrease in IMGU by skeletal muscle per se has been inferred from experiments where whole-body insulin-stimulated glucose uptake is decreased during the glucose clamp (after correction for any residual endogenous HGP) [28,117,120]. Direct evidence for the suppression of muscle IMGU by acute alcohol was also reported in humans using the A-V difference method [52]. In further support, an alcohol-induced decrease in insulin-stimulated glucose disposal by skeletal muscle has been consistently detected in rats using radiolabeled 2-DG [12,14,117,118]. In contradistinction, as described above, the alcohol-induced hepatic insulin resistance is more prominent in Long-Evans vs. Sprague-Dawley rats. It has been suggested this strain difference may be related to differences in the generation of reactive oxygen species [28].

That sort of double impact can cause blood sugar levels to drop to dangerously low levels, a condition known as hypoglycemia. Most diabetes medications work to john carter author at sober home lower your blood sugar (glucose) levels — and they’re particularly good at the job. Alcohol does the same thing, especially when consumed in larger quantities.
