Diarrhea on GLP-1s: What Helps
Diarrhea can happen on GLP-1 medications.
It is common during dose increases or when eating patterns change fast.
First goal: slow the gut down
- Choose bland, bulky foods for a few days.
- Reduce greasy foods and large meals.
- Keep meals smaller and simpler.
Hydration matters
Diarrhea depletes fluids.
Drink steadily through the day.
Probiotics and triggers
Some people benefit from a probiotic.
Others do better by removing one trigger at a time.
Common triggers include high-fat meals, sugar alcohols, and large portions.
If you have diabetes
Do not “treat lows” preemptively with constant carbs.
Match carbs to your plan and watch your numbers.
If diarrhea is causing lows, talk with your clinician about medication adjustments.
What usually happens over time
Many GI side effects improve after repeated weekly doses at the same dose level.
If symptoms spike after a dose increase, your clinician may hold the dose longer.
Red flags
- Severe dehydration
- Persistent vomiting
- Blood in stool
- Fever or severe belly pain
If you have these, contact your clinician urgently.
How MDHJ helps
Log diarrhea by date next to dose day and meals.
Patterns become obvious fast.
That makes your next step simple.
