GLP-1's and Coffee: Can You Drink Caffeine While on Semaglutide?
How Coffee Affects GLP-1 Users
1. Can Coffee Worsen GLP-1 Side Effects?
- Nausea and acid reflux: GLP-1's slows digestion, and coffee is acidic—this combination can lead to discomfort or heartburn.
- Dehydration risk: Caffeine is a mild diuretic, so drinking coffee without enough water may worsen constipation.
2. Does Coffee Impact Blood Sugar on GLP-1s?
- Black coffee is safe and may even improve insulin sensitivity.
- Sugary coffee drinks (with syrups or sweetened creamers) can spike blood sugar, counteracting GLP-1’s effects.
