Perianal itching can be managed by eating fibre in moderation.
Perianal itching is often caused by excessive dietary fibre
Sufficient fibre intake is one of the hallmark recommendations for a healthy diet. However, it is possible to have too much of a good thing. If you regularly consume large amounts of fibre, you may find yourself experiencing an unpleasant sensation known as perianal itching, or itching in the area around the anus.

Tips to manage the itch
