What are the effects of drinking alcohol on insulin resistance(IR)? IR is when cells don’t respond properly to insulin. Thus, they can’t use the glucose (sugar) in blood for energy. As a result, the body makes more insulin. So blood sugar levels increase. This becomes a vicious cycle. Sugar that your cells don’t use forms fat. And fat promotes IR.

The results tend to these.

• • Obesity
  • High blood pressure.
  • Type 2 diabetes.
  • High “bad” cholesterol.

Thus, any of these may be symptoms of the disease. Important, as many as a one in three people in the US suffers from IR. So it’s a serious and major health problem.

I. Study: Drinking Alcohol on Insulin Resistance

Researchers studied the effects of drinking alcohol on IR. To do so, their study included 280,194 people without diabetes. All were given health exams three or more times within a period of eight years. Their mean age was 38.2 years and 55.7% were male.

The median follow-up period was 4.13 years. During that time, alcohol drinking was linked with reduced insulin resistance. That is, drinking alcohol reduced the problem of insulin resistance.

The researchers concluded that alcohol drinking improves IR. Also, that increased drinking amounts may have preventive effects on the progression of IR.

II. Risk Factors

Things that increase chances (risk factors) for IR include these.

• • A diet high in carbs.
  • Having a fat belly.
  • Not getting enough exercise.
  • Smoking.
  • A family history of diabetes.
  • Older age.
  • Having hormonal disorders. 
  • Taking steroids, antipsychotics, or HIV meds.
  • Having high blood sugar levels during pregnancy.
  • Having either nonalcoholic fatty liver disease or polycystic ovary syndrome. 
  • Sleep apnea and other sleep problems.
  • Being African American, Latino, or Native American.
