Why Does My Butt Feel Burning Hot When I Have a Bowel Movement?

Many individuals experience pain around the anus after defecation, a condition primarily attributed to anal fissure. There are numerous reasons for anal fissure, primarily stemming from unhealthy habits in daily life. Irregular dietary habits and unbalanced nutrition often lead to dry stool, which can damage the anus over time. Therefore, it is crucial to alter lifestyle habits, consume foods rich in dietary fiber, drink plenty of water, and establish good bowel habits to prevent anal fissure.

What causes the burning pain around the anus after defecation? The most common reason for this significant anal pain after bowel movement is anal fissure, a condition related to dietary patterns in daily life. Patients often have a history of habitual constipation, and repeated episodes can lead to the formation of fissures around the anus, most commonly occurring in the posterior midline of the anus. Repeated ulcerations can also lead to local infections.

What are the causes of anal fissure? Firstly, abnormal bowel movements are a significant factor. Both constipation and diarrhea can contribute to anal and intestinal diseases, with constipation being the primary culprit. Constipation can prevent normal elimination, leading to the accumulation of harmful substances in the stool that are reabsorbed by the body, posing a health risk. Even when stool can be expelled, it often requires significant effort, which can lead to abrasions of the anal canal skin, causing swelling and ruptures. Diarrhea, a clinical manifestation of colon disease, can also contribute to anal fissure by irritating and causing ulceration of the anal canal skin due to bacterial infection.

Poor bowel habits, such as reading while using the toilet, can prolong the time spent squatting and defecating, increasing the risk of anal and rectal congestion and disease. Other unhealthy habits like smoking during bowel movements, straining excessively, and suppressing the urge to defecate can also contribute to anal fissure.

Sedentary lifestyles, lack of exercise, long-term standing or sitting, and consumption of stimulating foods like alcohol and spicy foods can all contribute to constipation and colon dysfunction, predisposing individuals to anal and intestinal diseases.

Chronic inflammatory conditions like anal sinusitis or anal gland inflammation can also lead to anal fissure. When these infections spread to the anus, they can cause subcutaneous abscesses that rupture into anal canal ulcers, which can develop into anal fissures if not treated promptly.

Anal stenosis, caused by congenital malformations, trauma, or improper surgical procedures, can also contribute to anal fissure by impeding smooth bowel movements. Excessive straining during defecation can damage the anus and lead to fissure formation.

Self-healing methods for anal fissure include:

1. Drinking plenty of water, especially first thing in the morning, to prevent constipation. Water intake should be increased, with options like plain water, saltwater, honey water, and soup before and after meals. Avoid excessive consumption of strong tea or sugary drinks, which can exacerbate fissure discomfort.

2. Eating a diet rich in high-fiber foods like fresh vegetables, fruits, sweet potatoes, oatmeal, and corn. Fiber softens stool, stimulates colon contractions, and reduces bowel movement difficulties.

3. Practicing pelvic floor exercises, which involve tensing and relaxing the muscles and soft tissues around the anus to improve blood circulation, strengthen the sphincter muscles, prevent anal relaxation, and enhance the anus's resistance to disease.

4. Regular exercise, such as gymnastics and jogging, promotes blood circulation, stimulates intestinal motility, improves pelvic health, and alleviates constipation discomfort.

5. Establishing a regular bowel movement schedule to avoid holding stool due to fear of pain.

6. Maintaining cleanliness after defecation, preferably with a warm sitz bath, to soothe anal spasms and reduce pain.
