Is it ok to exercise while having an anal fissure? specially exercises like pushups?

Yes: Exercise would be fine with an anal fissure. Activities that cause friction in the anal area, like bike riding, may not be recommended while the area is trying to heal.

Moderate exercise: Anal fissures are caused from passing large, hard stools. Poor diet (lack of adequate fiber and water intake) as well as inactivity can lead to constipation. Constipation leads to large hard stools. Moderate exercise, especially walking can help to regulate the stools and actually improve problems with anal fissures. Exercises that cause straining could potentially aggravate the fissure.
