Bristol Stool Form Scale Chart

The Bristol Stool Form Scale is a simple method of assessing how your digestive system is working. The scale consists of seven types of stool, each described with text and an image. We’ve created a downloadable version you can print out and use – you may want to put this up in your toilet.

The healthiest stool types are numbers 4 and 5, although the form will also be affected by what you have eaten in recent days. You may have seen a recent Department for Health campaign warning you to seek medical help if you detect blood in your stools or your stools have been looser than usual for more than three weeks. Both can be an indicator of more serious conditions and you should seek an expert opinion from your GP.

You can find out more about the Bristol Stool Form Scale within the bowel health section on this site.
