Can patients with anal fissures run?
In general, whether patients with anal fissures can run depends on the severity of their condition and overall physical health. If there is obvious discomfort or worsening symptoms, it is recommended to seek medical attention promptly. The specific analysis is as follows:

Patients with mild anal fissures who are in the recovery phase may engage in moderate running. In these cases, the fissure is shallow, without significant pain or bleeding, and the patient experiences no obvious discomfort. Moderate jogging can promote intestinal motility, help establish regular bowel movements, and improve blood circulation around the anus, thereby creating favorable conditions for healing. However, the intensity and duration of running should be carefully controlled to avoid overexertion.
Patients with severe conditions or those experiencing an acute flare-up should avoid running. At this stage, the fissure is deeper and accompanied by noticeable pain and bleeding. The physical jostling during running causes continuous friction of the perianal tissues, which may worsen the injury, increase pain and bleeding, and potentially raise the risk of infection due to increased sweating—impeding recovery.
Before running, individuals should assess their symptoms to determine the current stage of their condition. Wear loose, breathable clothing to minimize perianal friction, and clean the anal area promptly after running to keep the area dry. If pain intensifies or bleeding occurs during running, stop exercising immediately and rest. If symptoms persist or worsen, seek medical attention promptly to prevent delayed recovery.
