Overview
Constipation is when you have difficulty passing stool (poop) or you go to the toilet less often than is normal for you. Your stool may be hard, dry, or painful to pass. It is a common digestive problem and usually not serious, but it can make you uncomfortable.
Key facts
- It is normal to have different bowel habits—some people go three times a day, others three times a week.
- Drinking enough water and eating fiber can help prevent and relieve constipation.
- Occasional constipation is common, but if it lasts longer than three weeks, talk to your doctor.
Yes. Constipation affects millions of people worldwide. It is one of the most common digestive complaints seen by healthcare providers.

When to see a doctor
See a doctor urgently if:
- If you have any of the emergency symptoms listed above, call your local emergency number right away.
- If you see blood in your stool or have bleeding from your rectum, seek care the same day.
- If you have severe pain, vomiting, or a swollen belly, do not wait.
Book a routine appointment if:
- Constipation that lasts more than three weeks
- Constipation that keeps coming back or does not get better with lifestyle changes
- A sudden change in your bowel habits that is new for you
Diagnosis
Your healthcare provider will ask about your symptoms, how often you use the toilet, and any medicines you take. They may also ask about your diet, exercise, and medical history. In most cases, this is enough to diagnose constipation.
Tests that may be done
- A physical exam, including gently pressing on your belly
- A digital rectal exam (a gloved finger placed gently inside the rectum to check for blockages)
- Blood tests (if your doctor suspects a medical condition)
- Imaging tests or a look inside the bowels (like a colonoscopy), but usually only if symptoms are severe or concerning
What to expect at your appointment
Most people do not need any tests. Your provider may give you advice on diet, fluids, and habits. If your symptoms continue, they may suggest further tests to rule out other conditions.
Treatment
Treatment for constipation usually starts at home with simple lifestyle changes. If these do not help, your doctor can talk with you about other options, including medicines, but you should always follow their advice.
Self-care at home
- Drink more water throughout the day
- Add fiber-rich foods like fruits, vegetables, beans, and whole grains
- Try to be physically active for at least 30 minutes most days
- Do not ignore the urge to use the toilet
- Give yourself enough time and privacy on the toilet
- Consider using a small footstool under your feet when sitting on the toilet to make passing stool easier
Medical treatments
If lifestyle changes are not enough, your doctor may suggest a laxative or stool softener. There are many types, and some are not safe for long-term use. Always ask your doctor or pharmacist before using any product, and never take a stronger dose than recommended.
When is surgery considered?
Surgery is rarely needed for constipation. It may be considered if a structural problem, such as a blockage or a severe muscle problem, is found and does not get better with other treatments.
Living with this condition
You can manage constipation by paying attention to your body's signals and keeping a regular routine. Try to schedule toilet time after meals, and do not rush or strain.
Lifestyle tips
- Eat fiber-rich foods at every meal
- Stay active with walking or light exercise
- Drink enough fluids, especially during warm weather or when you exercise
- Manage stress with relaxation techniques or hobbies
Diet and exercise
A balanced diet with about 25 to 30 grams of fiber per day can help keep your stools soft and regular. Increase fiber slowly to avoid gas. Exercise helps keep your digestive system moving, so aim for regular, gentle activity.
Mental health and emotional wellbeing
Living with ongoing constipation can be frustrating and worrying. You may feel embarrassed or stressed about your symptoms. This is understandable, and you are not alone. Talking to your doctor or a counselor can help you cope. If you feel overwhelmed or have thoughts of harming yourself, reach out for help immediately by calling your local emergency number or a mental health crisis line.
Prevention
You can often prevent constipation by eating enough fiber, drinking plenty of fluids, staying active, and going to the toilet when you feel the need. It may not always be preventable, but these habits help.
Vaccines
No vaccine is available for constipation.
Screening programmes
There is no routine screening test for constipation. If you have a family history of bowel problems or have new symptoms, your doctor may recommend a colonoscopy or other tests.
Complications
If left untreated
- Hemorrhoids (swollen blood vessels in the rectum) caused by straining
- Anal fissures (small tears in the lining of the anus)
- Fecal impaction (stool stuck in the bowel that cannot be pushed out)
- Rectal prolapse (part of the rectum slips out of place)
Long-term outlook
Constipation is usually a short-term problem that improves with simple changes. Even when it is long lasting, most people find relief with the right support and treatment. Your doctor can help you create a plan that works for you.
