Constipation or diarrhea in adults: which doctor to see
Short-term bowel upsets happen to everyone — because of food, travel or stress. But if constipation or diarrhea lasts more than a week or two, keeps coming back or is accompanied by pain, it is worth sorting out with a gastroenterologist.
Common causes
- A diet low in fiber and water
- Intestinal infections and after-effects of antibiotics
- Irritable bowel syndrome
- Low activity, stress, a change of routine
- Thyroid disorders
- Medication side effects
When to seek urgent help
Do not wait for a scheduled visit if you have any of these signs:
- Blood in the stool or black, tar-like stools
- Diarrhea with high fever and signs of dehydration
- Constipation with severe pain and bloating, no stool for several days
- Unexplained weight loss
- Bowel habit changes that first appear after 45–50

Frequently asked questions
When is diarrhea an emergency?
If there are signs of dehydration (dry mouth, little urination, marked weakness), high fever or blood in the stool — do not wait, call 103 or go to a clinic.
Do I need a colonoscopy?
Not everyone: the doctor orders it when there are warning signs or after age 45. It usually starts with an examination and tests.
