Constipation is where you have changes to how you poo, including not pooing as often or finding it hard to poo. It's common and it affects people of all ages. You can usually treat it with simple changes to your diet and lifestyle.

This page is about constipation in adults. There's separate information on constipation in babies and children.

Check if it's constipation

You may also have a stomach ache and feel bloated or sick.

If you're caring for someone with dementia or an older person, constipation may be easily missed. Look out for any behaviour changes such as confusion, as it might mean they are in pain or discomfort.

What causes constipation

Constipation in adults has many possible causes. Sometimes there's no obvious reason.

The most common causes include:

Constipation is common during pregnancy and after giving birth. It is also more common if you are black or if you are over 65 years old.

Constipation can also be caused by a medical condition such as diverticular disease or bowel cancer, but this is rare.

How you can treat and prevent constipation yourself

Making simple changes to your diet and lifestyle can help treat constipation.

It's safe to try these simple measures when you're pregnant.

You may notice a difference within a few days. Sometimes it takes a few weeks before your symptoms improve.

Make changes to your diet

To make your poo softer and easier to pass:

Improve your toilet routine

Keep to a regular time and place and give yourself plenty of time to use the toilet.

Do not delay if you feel the urge to poo.

To make it easier to poo, try resting your feet on a low stool while going to the toilet. If possible, raise your knees above your hips.

Consider increasing your activity

A daily walk or run can help you poo more regularly.

Speak to a pharmacist for advice

Speak to a pharmacist if diet and lifestyle changes are not helping.

They can suggest a suitable laxative. These are medicines that help you poo more regularly.

Most laxatives work within 3 days. They should only be used for a short time.

Non-urgent advice: See a GP if you:

  • are regularly constipated
