Finding your IBS triggers with a bowel diary
There’s no single test for IBS, and no single IBS diet. The most powerful tool is a simple, honest diary — exactly what NHS bowel clinics ask patients to keep.
What IBS is
Irritable bowel syndrome is a common, often long-term condition causing tummy pain and cramps, bloating, wind, and diarrhoea, constipation or both. It’s usually diagnosed from your symptoms, with routine tests to rule out other conditions. It can’t be cured, but it can be managed very effectively.
What a bowel diary records
NHS clinics ask patients to note, for each visit: date and time, Bristol stool type, leakage, bloating, time on the toilet, straining, pain or bleeding, laxative or anti-diarrhoeal medicine and dose, and anxiety — plus everything eaten and drunk. Poochievements captures all of this in a few taps.
Common triggers to tag
- Caffeine — stimulates the bowel wall
- Alcohol and spicy food
- Fatty or ultra-processed foods
- Dairy (lactose), onion/garlic, beans/pulses and some sweeteners — often linked to wind and bloating
Turning a diary into answers
After two to four weeks, compare days you ate a suspect food with days you didn’t. Poochievements’ trigger detective does this automatically, showing how often stools were abnormal with and without each tag. Remember: correlation isn’t proof. Before cutting out food groups, speak to your GP or a dietitian — they may suggest a structured elimination plan.
Don’t forget the gut–brain link
Stress and anxiety can trigger IBS flares through the gut–brain axis. Logging how you feel alongside what you eat often reveals patterns food alone can’t explain.
Frequently asked questions
How long should I keep a food and bowel diary for IBS?
Two to four weeks of consistent entries usually gives enough data to spot patterns. Share it with your GP or dietitian before making big diet changes.
