Irritable Bowel Syndrome (IBS) Nutrition Guide
IBS can affect digestion in different ways. Some people experience constipation, others diarrhea, and some alternate between both.
The good news?
Small, steady nutrition changes can make a big difference in comfort, bowel habits, and daily quality of life.
This guide is designed to help you:
✔ Reduce bloating
✔ Improve bowel regularity
✔ Minimize urgency or discomfort
✔ Identify foods that support your digestion
Daily Habits That Help IBS
✔ Eat regularly
Try to eat meals and snacks at consistent times each day. Skipping meals may worsen symptoms.
✔ Choose smaller portions
Large meals can trigger cramping or urgency.
✔ Increase fiber slowly (if needed)
Fiber can help — but too much too fast may worsen gas or bloating.
✔ Drink fluids
Aim for 6–8 cups daily unless your provider has told you otherwise.
✔ Notice food triggers
Keep a simple food + symptom journal.
