What should I know about alcohol while on a GLP-1?

GLP-1 medications slow stomach emptying, and alcohol can irritate the stomach. Together, they may increase nausea, vomiting, or heartburn - especially after a recent dose change. Alcohol also adds calories quickly and can slow weight loss progress. You don't have to quit entirely, but less is better, especially during dose increases.

Timing: If you're still increasing your dose or experiencing side effects, consider skipping alcohol until you stabilize. On maintenance, choose low-symptom days.

Amount: Follow standard guidelines - up to 1 drink/day for women, 2 for men. Less is better for weight loss results.

How to drink smarter: Sip slowly. Pair with protein (never on an empty stomach). Drink water between alcoholic drinks. Aim for 2-3 liters of fluid per day.

Lower-calorie options: Dry wine (5 oz), light beer (12 oz), spirits (1.5 oz) with seltzer or diet mixers, hard seltzers with 0-2 g sugar.

Avoid: Sugary cocktails (margaritas, piña coladas), full-sugar mixers, large craft beers - these stack calories and can worsen nausea and reflux.

Blood sugar warning: If you also use insulin or sulfonylurea, alcohol can contribute to low blood sugar. Plan food, spacing, and monitoring.
