It is not always possible to prevent an anal fissure. However, one of the best ways to prevent one from developing is to avoid becoming constipated.
Preventing constipation
To prevent constipation you should:
- Eat plenty of fibre, at least 18g a day (see Anal fissure – Treatment).
- Drink plenty of water, at least 1.2 litres (six to eight glasses a day) or more when you are exercising or when it is hot.
- Do not ignore the urge to go to the toilet.
- Keep active. A minimum of 30 minutes of physical activity a day, five times a week, is the recommended amount of activity that you should be doing.
See the Health A-Z topic about Constipation – Prevention for more information and advice.
