Constipation: causes, warning signs & what to do
Infrequent or hard-to-pass stools are very common and usually respond to fibre, fluids and activity. A change in habit, or bleeding, needs attention.
Common causes of constipation
- Low fibre or fluid intake
- Inactivity
- Ignoring the urge to go; travel/routine change
- Medicines (painkillers, iron, some others)
- Underactive thyroid
- IBS; rarely, a bowel obstruction or growth
When to see a doctor urgently
- Constipation with severe abdominal pain, vomiting and a bloated tummy — seek urgent care
- Blood in the stool or from the back passage
- A persistent change in bowel habit over weeks (especially over 40)
- Unexplained weight loss with constipation
Frequently asked questions
How can I relieve constipation naturally?
More fibre (fruit, vegetables, whole grains), plenty of fluids, regular activity, and not delaying when you feel the urge. Laxatives help short-term if needed.
When should constipation be investigated?
A new, persistent change in bowel habit, bleeding, or weight loss — especially after 40 — should be reviewed to rule out serious causes.
