Can patients with anal fissures go swimming?

Generally, patients with anal fissures may swim appropriately if their condition is in remission and the wound has largely healed. However, swimming is not recommended during acute episodes, when wounds are unhealed or show signs of infection. If in doubt, it's advisable to consult a healthcare provider beforehand. Detailed explanations are as follows:

If the anal fissure is in the remission phase—without significant pain or bleeding, with only mild discomfort remaining, and without recurrence for a sustained period—swimming moderately may help promote blood circulation around the anus through water massage, thereby aiding further healing. However, it is essential to choose a clean, well-maintained pool with properly treated water to avoid irritation or contamination of the anal area. Swimming time should also be limited to prevent excessive fatigue that could impair recovery.

If the anal fissure is in an acute phase, with obvious pain, bleeding, or signs of infection such as redness, swelling, and increased discharge, swimming is not advised. Although pool water is disinfected, it may still contain bacteria capable of entering unhealed wounds and causing infection. Additionally, continuous water impact and friction on the anal area during swimming can worsen tissue damage, increase pain and bleeding, and delay healing.

Prior to swimming, patients with anal fissures should assess their current condition. After swimming, they should promptly clean the anal area with warm water and dry it thoroughly. If symptoms such as increased pain or bleeding occur after swimming, they should stop immediately and seek medical evaluation.
