Alcohol Awareness

A spirited review of alcohol-related research.

Jeopardy Cocktail: Mix one part diabetes, one part alcohol, and you take your chances.

In honor of National Alcohol Awareness Month, this column reviews a wide variety of research findings related to diabetes and alcohol consumption, in addition to some basic approaches to minimize negative consequences. Keep in mind that drinking alcohol interferes with the liver's ability to release stored glucose and therefore affects blood glucose values in a most unpredictable way.

What have the researchers discovered? See if you can make sense of some of the latest conclusions:

  • Hypoglycemia and alcohol consumption reduce cognitive function. I love studies like this. We already know hypoglycemia (glucose less than 70) in and of itself interferes with thinking, as does alcohol, so why not combine both and see what happens! However, did you know that a hypoglycemic driver can be mistaken for being drunk? As an ex-ER nurse, I beg you not to drink and drive, and as a certified diabetes educator, I encourage you to test your glucose before getting behind the wheel.
     
  • A reduced incidence of type 2 diabetes is associated with low to moderate alcohol consumption. That doesn’t mean we all should load up our grocery carts with booze and take up drinking because alcohol can also increase blood glucose levels after meals. This suggests there is a delicate balance between the benefits and harmful effects of alcohol. Moderate consumption of alcohol (no more than 1 drink a day for women and 2 drinks per day for men) has an anti-inflammatory action which could lower cardiovascular mortality, yet can put one at risk for alcohol abuse.
     
  • Drinking moderate amounts of wine, beer, or hard alcohol is associated with better blood glucose control among healthy adults, particularly women. Women who drank any kind of alcohol had lower A1C levels (3-month glucose averages) than non-drinkers. In men, only wine was associated with lower glucose levels perhaps because wine is associated with a healthier lifestyle, such as not smoking and a higher level of education. Beer drinking among men is linked to smoking, hostility, and a less healthy diet. OK. This study was done in Europe where it can take hours to get through a meal. Quite a different lifestyle than in the U.S. where we inhale our food.
     
  • Alcohol overdose is the leading cause of death due to hypoglycemia in the United States. Hypoglycemia is one of the main causes for people with diabetes to go to the emergency room.
     
  • Alcohol consumed in the evening may cause hypoglycemia in people with type 1 after breakfast the next day. This hits many people by surprise and can be quite dangerous when coupled with an early morning exercise routine.
     
  • Alcohol is toxic to nerves. Some studies show that even light regular drinking (2 drinks a week) can cause nerve damage.
     
  • Moderate alcohol levels are linked to a decrease in insulin levels (while drinking for 90 minutes after a meal). Lack of insulin can lead to diabetes.
     
  • More than 3 alcoholic drinks a day increases the risk of type 2 diabetes by 43 percent.

After reading this, is your mind spinning as if you already had a drink? Let’s look at some practical pointers should you decide to enjoy a social cocktail:

1. Check with your medical provider about risks of alcohol on your diabetes.

2. Never drink on an empty stomach. It’s best to drink alcohol slowly while having something to eat.

3. Limit sweetened, alcoholic beverages that contain fruit juice/sugar content.

4. Test, Don’t Guess your blood sugar. The next time you consider adding a little alcohol, play it smart. Here’s to you: Cheers!

As a Type A personality with a perfectionist streak, diabetes management is something that easily gets under my skin. If I can’t do something perfect, then I’d much rather just not do it at all. Which is why burnout creeps up on me super fast. A few days of pesky numbers and I am ready to throw all things diabetes out the window and watch it get hit by an 18-wheeler. So attempting to get my A1c into the lowest possible range ever has proven incredibly tasking for my perfectionist...
