When to see a doctor
See a doctor urgently if:
- Constipation lasting more than three weeks despite home remedies
- No bowel movement for 5 to 7 days despite feeling the urge
- Severe bloating or cramping that does not improve
- Blood in the stool
- Unexplained weight loss or loss of appetite
Book a routine appointment if:
- You are over 50 and notice a change in bowel habits
- You have a history of bowel conditions
- Constipation is interfering with your work or daily life
- You feel a painful lump in your bottom (possibly a hemorrhoid)
- You need to use a laxative regularly to have a bowel movement
Diagnosis
Your doctor will ask about your symptoms, medical history, how often you open your bowels, and what your stools look like. They may feel your tummy and, with your permission, do a quick rectal exam (a check using a gloved finger) to feel for a blockage.
Tests that may be done
- Blood tests to check for thyroid problems or diabetes
- Stool sample (poo test) to look for signs of infection or inflammation
- X-rays or scans to look at your bowel
- A colonoscopy or sigmoidoscopy — a thin tube with a camera that looks inside your bowel (usually done if you have warning signs or are over 50)
What to expect at your appointment
A doctor will take time to listen to your story. Most people do not need tests. If tests are needed, they will explain why and how to prepare for them.
Treatment
Treatment focuses on easing symptoms and helping you return to a normal bowel habit. It often involves lifestyle changes like eating more fiber and drinking enough fluid. Your doctor may suggest a plan that is safe for you.
Self-care at home
- Eat more fiber-rich foods such as oats, wholemeal bread, apples, pears, vegetables and beans
- Drink plenty of water — aim for 6 to 8 glasses a day unless your doctor says otherwise
- Try to be physically active every day — even a short walk helps
- Set aside time to sit on the toilet after meals, when your bowels are naturally more active
- Do not ignore the urge to go to the toilet
- Gently massage your tummy or rock forward while sitting on the toilet to help with passing stool
Medical treatments
If lifestyle changes are not enough, your doctor or pharmacist can suggest a laxative (a medicine that helps you pass stool). Laxatives come in different types, such as bulk-forming, osmotic, stimulant or stool softeners. They should only be used as directed and for a short time unless a doctor advises otherwise.
Living with this condition
For most people, constipation is a temporary problem. If it continues, you will need to build habits that help your bowels work well. Be patient, as it may take a few weeks to get back into rhythm.
Lifestyle tips
- Keep a regular toilet schedule
- Have a high-fibre breakfast every day
- Stay hydrated throughout the day
- Move your body regularly
- Limit processed foods, high-fat foods and excessive caffeine
- Avoid smoking and limit alcohol
Diet and exercise
Eat plenty of fruits, vegetables, whole grains and legumes. Drink at least 1.5 to 2 litres of water a day unless you have fluid restrictions. Exercise like walking or swimming can help stimulate the muscles in your digestive tract.
Mental health and emotional wellbeing
Constipation can be uncomfortable, embarrassing and frustrating. It can affect your mood and quality of life. Talking to your doctor or a counsellor can help you manage these feelings.
Prevention
Yes, in many cases. A fiber-rich diet, enough fluids, and regular activity are the most effective ways to prevent constipation. Learning to respond to the urge to go to the toilet and making time for it also helps.
Screening programmes
There is no routine screening for constipation. However, if you are over 50 or have symptoms like blood in the stool, your doctor may recommend a screening test like colonoscopy to rule out bowel cancer.
Complications
If left untreated
- Hemorrhoids (swollen veins around the anus)
- Anal fissures (small tears in the skin around the anus)
- Fecal impaction (a hard mass of stool stuck in the bowel)
- Prolapse (a part of the rectum pushes out through the anus)
- In severe cases, bowel obstruction (a blockage in the bowel) leading to vomiting and severe pain
Long-term outlook
The outlook for constipation is very good. Most people improve quickly with simple lifestyle changes. If a medical condition is the cause, treating that condition will often ease the constipation. With the right help, you should be able to pass stools comfortably and regularly.
