What counts as a normal bowel pattern, why habits change, what can help, and when a change should be checked by a GP.
Quick answer: There is no single normal. An NHS hospital leaflet says anything from three times a day to three times a week can be normal, if it is normal for you. A change that lasts longer than three weeks should always be checked, and blood in your stool should be seen by a GP.

What counts as normal?
How often people open their bowels varies. According to an NHS leaflet from Royal Berkshire NHS Foundation Trust, normal can be anything from three times a day to three times a week, as long as it is normal for you. What matters most is your own usual pattern and whether it changes.
Why bowel habits change
Many everyday things can shift your pattern for a few days: a change in diet or meal times, less fluid, less activity, travel, stress, a stomach bug or a new medicine. NHS leaflets also note that some medicines cause constipation, and that caffeine stimulates the bowel in some people.
What can help
- Eat enough fibre and build up gradually. See How to eat more fibre.
- Drink enough fluid. See How does hydration support digestive health?.
- Stay active, and keep to regular meal times.
- Do not ignore the urge to go.
- Ask your pharmacist if a medicine may be affecting your bowel.
When to speak to a GP
The Royal Berkshire leaflet says changes in bowel habit that last longer than three weeks should always be investigated, and that new constipation or diarrhoea lasting more than three weeks should be reported to a doctor. Ask your GP for advice sooner if you see blood in your stool, have ongoing pain, bloating that does not go away, or unexplained weight loss. The NHS also notes that bloating with certain other symptoms needs prompt advice. Most people with a bowel change do not have a serious condition, but it is better to check early.
Should I try a colon cleanse supplement?
If your habits have changed, finding out why comes first. The US National Center for Complementary and Integrative Health (NCCIH) says there is no convincing evidence that detox or cleansing programmes remove toxins, so speak to a healthcare professional before trying one.
