When to see a doctor
See a doctor urgently if:
- You have severe abdominal pain or a swollen, hard belly
- You see blood in your stool or vomit
- You cannot pass gas or stool and feel sick
- You have not had a bowel movement for a week and are in discomfort
Book a routine appointment if:
- Constipation lasts for more than 3 weeks
- You rely on laxatives often and still have hard stools
- Your symptoms keep getting worse despite diet and lifestyle changes
- Constipation is affecting your daily life or causing a lot of worry
Diagnosis
A doctor will ask about your symptoms, how often you go to the toilet, your diet, fluid intake, medicines, and any other health conditions. They may gently press on your belly to check for tenderness.
Tests that may be done
- A physical exam, which may include a rectal exam to check for blockages
- Blood tests to check for thyroid problems or other causes
- A plain X-ray or a colonoscopy if symptoms are persistent or severe or if there is a concern about something more serious
What to expect at your appointment
The appointment usually starts with a conversation about your bowel habits and daily life. Most people with occasional constipation do not need tests. If your doctor wants to investigate, they will explain each step and why it is needed.
Treatment
Treatment for constipation usually begins with simple lifestyle changes — more fibre, more fluids, and regular movement. If these are not enough, your doctor or pharmacist can discuss options with you.
Self-care at home
- Try to drink 6 to 8 glasses of fluid a day, mainly water
- Gradually add more fibre at mealtimes, such as oats, fruits, veg, and wholemeal bread
- Do regular gentle exercise, like walking, to help your bowels move
- Set a calm toilet routine — try going at the same time each day, especially after breakfast
- Do not delay when you feel the urge to go
Medical treatments
When lifestyle changes do not resolve constipation, your doctor or pharmacist may suggest a short course of a laxative. These work in different ways — some soften the stool, some stimulate the bowel, and some draw water into the gut. Your healthcare team can help you choose a type that is appropriate for you and explain how long to use it. Never take more than recommended, and always ask your doctor before starting any constipation medicine if you have an underlying health condition.
When is surgery considered?
Surgery is rarely needed for constipation. It may be considered only when there is a physical blockage, a severe structural problem, or when other treatments have failed and the cause is clearly surgical.
Living with this condition
Try to keep a relaxed approach to the toilet. Set a routine, allow enough time, and do not strain. Keeping a simple diary of your bowel movements, diet, and fluids can help you see what works for you.
Lifestyle tips
- Eat meals at regular times and include fibre with each meal
- Stay physically active most days — a short walk after meals can help
- Take bathroom breaks whenever you feel the urge
- Manage stress with breathing exercises, rest, or activities you enjoy
Diet and exercise
Aim for a fibre-rich diet of fruits, vegetables, whole grains, beans, and nuts. Increase fibre gradually to avoid bloating. Pair this with regular moderate exercise, like brisk walking, swimming, or cycling, for at least 30 minutes on most days.
Mental health and emotional wellbeing
Constipation can be uncomfortable, embarrassing, and sometimes painful. Worrying about it can make symptoms feel worse. It is normal to feel frustrated or anxious. Be kind to yourself and treat it as a common health issue that can improve — you are not alone.
Prevention
In many cases, yes. Eating a balanced diet with plenty of fibre, staying well hydrated, moving regularly, and not holding in the urge can all help prevent constipation. If you take medicines that cause constipation, your doctor may suggest ways to reduce this.
Complications
If left untreated
- Haemorrhoids (swollen blood vessels around your bottom)
- Anal fissures (small tears in the skin around the anus)
- Faecal impaction (a hard plug of stool that blocks your bowels)
- Bowel blockage, which can cause severe pain and vomiting
- Rectal prolapse (part of the rectum slips down out of place)
Long-term outlook
The outlook is generally good. Most people with constipation respond well to simple changes. Even for chronic or severe constipation, a doctor can help you create a safe and effective plan. With patience, the right support, and a step-by-step approach, your symptoms can get better.
