Chronic Constipation: Causes & When to See a Doctor
Constipation is one of the most common digestive complaints, and most of the time it is related to diet, fluids and lifestyle, and improves with simple measures. However, a recent change in bowel habit — particularly new constipation in an adult, or constipation with other warning signs — deserves assessment, because occasionally it points to something that needs treatment.
This page explains what chronic constipation can mean, when it is worth investigating, and how it is managed.
What does chronic constipation mean?
Constipation generally means infrequent, hard or difficult-to-pass stools. It becomes 'chronic' when it persists over weeks or months. Most chronic constipation is functional — linked to a low-fibre diet, inadequate fluids, inactivity or ignoring the urge to go — and responds well to lifestyle measures.
What matters most is change. New, persistent constipation in an adult, especially with bleeding, weight loss or a narrowing of the stool, is the pattern that warrants a closer look.
Common causes
- A low-fibre diet, inadequate fluids and inactivity
- Ignoring the urge to pass stool; changes in routine
- Certain medicines (including some painkillers)
- Irritable bowel syndrome
Less common causes
- A narrowing of the bowel from colon cancer or a stricture
- Diverticular disease
- An underactive thyroid or other metabolic causes
- Pelvic-floor and outlet problems (obstructed defecation)
When should you seek medical attention?
- A recent, persistent change to constipation, especially in adults over 45–50
- Constipation with rectal bleeding or blood in the stool
- Constipation with unexplained weight loss or tiredness
- A narrowing of the stool, or a feeling of incomplete emptying
- Constipation alternating with diarrhoea, or with abdominal pain
How is the cause diagnosed?
- A careful history and examination, including of the back passage
- Blood tests (including thyroid and for anaemia)
- Colonoscopy where there are warning signs or a change in habit
- Specialised tests for pelvic-floor function in selected cases
How chronic constipation is treated
Most chronic constipation improves with a high-fibre diet, plenty of fluids, regular activity and good toilet habits, sometimes with the help of laxatives. Where a specific cause is found — such as an underactive thyroid or a medicine — treating that resolves the problem. Pelvic-floor problems have their own specific treatments.
The key is to distinguish straightforward, lifestyle-related constipation, which is very common, from the less common situations where constipation is a sign of something that needs treatment.
When surgery may be needed
The great majority of constipation needs no surgery. Surgery becomes relevant only when constipation is caused by a condition that requires an operation — most importantly, a narrowing of the bowel from colon cancer, or certain structural and pelvic-floor problems. A GI surgeon can determine whether any such cause is present.

Chronic Constipation: frequently asked questions
When should I worry about constipation?
Most constipation is harmless and lifestyle-related. It is worth assessing when it is a recent, persistent change — especially in adults over 45–50 — or when it comes with rectal bleeding, weight loss, a narrowing of the stool, or abdominal pain. These features warrant a closer look, often with a colonoscopy.
Can constipation be a sign of cancer?
Usually not — but a new, persistent change in bowel habit to constipation, particularly with bleeding or weight loss, can occasionally be a sign of colon cancer narrowing the bowel. This is exactly why a change in bowel habit is assessed rather than ignored.
