Talking about bowel problems

Doctors or nurses may ask you to describe your bowel habits and what your poo (stool) looks like. This helps with your diagnosis.

There is a scale of different types of stool called the Bristol stool chart. It helps when describing what your poo looks like. It has 7 different levels shown in the image below:

It's important that you speak to your healthcare team if you have noticed a change to your poo that isn’t normal for you. The earlier changes are picked up, the easier it is to sort the problem out.

You might find it embarrassing to talk about your bowels and bowel problems. Talking about your bowels and going to the toilet are very private matters for many people. But nurses and doctors are used to talking about these things and will want to help you.

It may help to use the Bristol scale to tell your doctor or nurse what it is like. For example, you could say "It is usually type 4 but for the last few days has been type 6".
