Glucagon-Like Peptide-1 Receptor Agonists (GLP-1’s) have been discussed in this blog numerous times. This post is another that focuses on the inherent effects of GLP-1’s, or the effects on GLP-1’s on other compounds. In particular, it deals with the interaction of GLP-1’s and drinkable or edible substances that contain alcohol.
Ethyl alcohol, or ethanol, is the alcohol found in all types of alcoholic beverages. Wine, whisky, vodka, beer, you name it, they all contain ethyl alcohol. Physicians have adopted an acronym-like abbreviation used in written communications with other professionals that means an alcoholic beverage. If you see ETOH in a patient note, you’ll know it stands for ethyl alcohol, or alcohol in general.
Studies have shown that “GLP-1’s can lower your tolerance to alcohol” meaning that when take a GLP-1 you will feel inebriated with a lesser amount of alcohol than you would typically, and you’re likely to feel nausea and dizziness sooner than usual. Metabolic effects are also more likely because “alcohol contains more calories than people realize,” counteracting the weight loss effect of GLP-1’s. They also contribute to dehydration, cause nausea, affect insulin sensitivity, and can worsen kidney function. They can also contribute to high blood pressure.
“Alcohol mimics sugar overload, [increasing] insulin demand, and dehydrating the kidneys, while GLP-1’s counter this by stabilizing glucose and reducing inflammation….Booze accelerates insulin resistance, forcing the kidneys to filter excess glucose and toxins, leading to overload and progression of chronic kidney disease.” So, it’s best to drink low calorie wines and avoid high proof or sugary mixers.” Alcohol in moderation is the best policy in nearly every medical/metabolic situation, and especially when mixed with drugs like GLP-1’s that have profound metabolic effects.
Bottom line: If you take any GLP-1 for any reason, consume any alcoholic beverage with caution and in limited amount.
