Burning sensation in the buttocks during bowel movements

A burning sensation in the anus during bowel movements may be caused by non-disease factors such as consuming excessively spicy foods or having dry stools. However, it's also important to be alert for underlying medical conditions such as acute external hemorrhoids, anal fissures, or proctitis. If symptoms recur or are accompanied by other issues, interventions including medication, physical therapy, or surgery are generally available to prevent further progression of the disease.

1. Non-Disease Factors

A burning sensation during bowel movements due to non-disease causes is commonly linked to eating spicy food or having dry stools. Symptoms usually improve significantly by adjusting the diet—favoring light, easily digestible foods—and increasing fluid intake.

2. Disease-Related Factors

1. Acute External Hemorrhoids

A burning sensation during bowel movements may result from external hemorrhoids. Treatment includes sitting baths using herbal medicines or potassium permanganate diluted in warm water, performed morning and evening. After drying the area, insert hemorrhoid suppositories into the anal canal and apply hemorrhoid ointment externally to reduce inflammation and swelling. Oral administration of Diosmin tablets may also help improve local microcirculation.

2. Anal Fissure

An anal fissure can also cause a burning sensation during defecation. Appropriate use of oral stool softeners or laxatives helps maintain regular bowel movements and prevents worsening of the condition. Local anesthetic agents such as lidocaine can be applied to relieve pain. Sitz baths promote blood circulation and aid in wound healing.

3. Proctitis

Severe proctitis can lead to a burning sensation during bowel movements. Treatment typically involves antimicrobial agents like Norfloxacin or antiviral medications such as Acyclovir. Other therapeutic options include endoscopic argon plasma coagulation and hyperbaric oxygen therapy. In cases where proctitis is caused by an anal fistula, surgical intervention may be required.

In daily life, maintain a light diet and avoid frequent consumption of spicy or irritating foods. Promptly treat any related medical conditions and pay attention to personal hygiene to prevent complications.
