GI symptoms are the #1 complaint with incretin medicines. Most are manageable, but they’re easier when you have a plan before the first dose increase.
Nausea: what helps most people
- Smaller meals, slower eating, and stopping at ‘comfortably full’
- Protein-first meals (helps stabilise appetite and reduces grazing)
- Avoiding very fatty meals around injection day
- Ginger tea or bland foods temporarily if needed
- Hydration - nausea often reduces fluid intake
Constipation: build a simple system
- Increase fibre gradually (not all at once).
- Prioritise water and movement (a daily walk helps).
- Choose fibre foods you tolerate: kiwifruit, oats, legumes, veg soups.
- If needed, discuss short-term options with a pharmacist/clinician.
Reflux/indigestion
- Avoid late-night large meals; allow 2–3 hours before lying down.
- Reduce trigger foods temporarily (spicy, very fatty, alcohol).
- Discuss persistent reflux with a clinician.
When symptoms mean ‘get checked’
Seek prompt medical advice for severe or persistent vomiting, signs of dehydration, severe abdominal pain, black stools, or any symptom that worries you.
If side effects are pushing you to quit
Don’t silently stop and disappear. A slower titration plan, better meal structure, or targeted symptom support can make the difference between quitting early and succeeding long-term.
