Heavy drinking, particularly in diabetics, also can cause the accumulation of certain acids in the blood that may result in severe health consequences. Finally, alcohol consumption can worsen diabetes-related medical complications, such as disturbances in fat metabolism, nerve damage, and eye disease. Although detailed data on alcohol use were collected prospectively in the ADVANCE trial, the current study is a retrospectively performed (post hoc) analysis. The current analyses are based on the consumption of alcohol at the time of randomization in the ADVANCE trial. This may not have accurately captured the prior or subsequent behavior of the participants, and we are unable to assess the duration of alcohol consumption.
However, for people with diabetes, alcohol consumption can affect blood sugar levels. Insulin resistance does not immediately lead to overt diabetes, because the patient’s pancreatic beta cells initially can increase their insulin production enough to compensate for the insulin resistance. In fact, insulin-resistant people have higher than normal insulin levels (i.e., are hyperinsulinemic1). In time (i.e., probably after several years), however, the pancreas cannot keep up with the increased demand for insulin; although insulin production still may be higher than in nondiabetic people, it is no longer sufficient to overcome insulin resistance.

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). As a result of the immune system’s attack, the beta cells can no longer produce insulin. Because insulin is a key metabolic hormone, insulin deficiency leads to major impairment of the body’s regulation of carbohydrate, lipid, and protein metabolism. Behavioral genetic research suggests that there is a heritable component to experiencing alcohol-induced blackouts (Luczak et al., 2006; Nelson et al., 2004; Slutske et al., 1999). Two recent studies explored genetic influences by examining the potential effects of family history of alcohol problems on blackout occurrence (LaBrie et al., 2011; Marino and Fromme, 2015). In a study of 2,546 college students, LaBrie and colleagues (2011) found that a family history of alcohol problems increased the likelihood of blacking out.
While blackouts are a frightening experience, treatment can allow people to lead a normal life without the fear of falling unconscious or losing their memory. With treatment, most people will be able to continue their daily activities. If a person’s blackouts are related to an underlying medical condition, they should stop once the person receives treatment to manage the condition. Low blood pressure typically causes syncope blackouts because the heart cannot pump enough oxygen-rich blood to the brain. When a person consumes a very large volume of alcohol, an en bloc blackout may occur. If this happens, they will not remember anything that they did while they were drinking.
Diabetic Diet: Foods That Raise Your Blood Sugar Levels
Any person with diabetes type 1 or type 2 that chooses to drink alcohol is advised to monitor their drinking very closely. Excessive drinking and alcohol use can become dangerous quickly for diabetics. People with diabetes should be especially cautious about drinking alcohol.

- Type 1 diabetes is an autoimmune disease—that is, a disease in which the body’s immune system attacks and destroys not only foreign molecules or organisms but also some of the body’s own cells.
- “It’s like a temporary gap in the tape,” Aaron White of the US’s National Institute on Alcohol Abuse and Alcoholism told BBC Future in an earlier story on blackouts and drinking.
In an effort to better characterize blackouts, researchers should collect detailed information about past and current alcohol consumption patterns, as well as other illicit drug use. Optimally, actual BrACs or blood draws could be collected to back-extrapolate can diabetics get drunk peak BACs to the time of blackout. This information will enable researchers to statistically control for the direct effects of alcohol consumption and examine factors that influence alcohol-induced blackouts over and beyond the amount of alcohol consumed.
Diabetic Shock And Insulin Reactions
Any alcohol that the liver does not break down is removed by the lungs, kidneys, and skin through urine and sweat. Neuropathy, in addition to other factors (e.g., vascular disease in the penis or altered hormone levels), also may contribute to impotence, which is a common and troublesome complication in diabetic men. The nerves that control erection are part of the autonomic nervous system, which controls numerous vital processes that occur without conscious efforts (e.g., breathing and the contractions of the gut necessary for proper digestion).
For people with type 1 and type 2 diabetes who take insulin or other diabetes medications that lower blood sugar levels, drinking alcohol needs to be done thoughtfully. The current study is one of the largest to explore the relationship between alcohol consumption and vascular outcomes and mortality in patients with type 2 diabetes. The participants in the study cohort were well characterized, and the study outcomes had been prespecified and were independently adjudicated.
People with diabetes should be sure to pay attention to any potential warnings. 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. 1The prefix “hyper-” always indicates higher than normal levels of a substance, whereas the prefix “hypo-” indicates lower than normal levels.
- The effects of alcohol use were explored using Cox regression models, adjusted for potential confounders.
- The study end points were cardiovascular events (cardiovascular death, myocardial infarction, and stroke), microvascular complications (new or worsening nephropathy or retinopathy), and all-cause mortality.
- Additionally, elevated glucose levels decrease the ability of red blood cells to carry nutrients to the wound, limiting the effect of white blood cells in fighting infections.
- If this happens, they will not remember anything that they did while they were drinking.
- In addition to being highly painful and potentially fatal, this inflammation may interfere with the production of insulin, thereby potentially worsening control of blood sugar levels and making hypertriglyceridemia a particularly serious complication in diabetics.
