Why Does My Bum Hurt When I Poo?

Discomfort during bowel movements is common, ranging from mild irritation to sharp pain. While often temporary, persistent or severe pain can indicate an underlying condition.

Common Reasons for Discomfort

Hemorrhoids are swollen veins in the rectum or around the anus. They can be internal, often painless but prone to bleeding, or external, causing pain, itching, or a visible lump. Straining during defecation, prolonged sitting, pregnancy, or chronic constipation and diarrhea can contribute to their development.

An anal fissure is a small tear in the lining of the anus. Hard or large stools and excessive straining cause sharp, stinging pain during and after bowel movements, sometimes with bright red bleeding. Fissure pain can be intense and last for hours, often due to anal sphincter muscle spasms.

Constipation, defined as infrequent or difficult bowel movements, also causes pain. When food moves slowly, the colon absorbs excessive water, making stools hard and dry. Passing these hard stools strains the anal canal, directly causing pain or worsening conditions like hemorrhoids and anal fissures.

Other Potential Conditions

Other conditions can also cause pain during defecation. Inflammatory Bowel Disease (IBD), including Crohn’s disease and ulcerative colitis, involves chronic digestive tract inflammation. This can manifest as pain, perianal abscesses, fistulas, or fissures, significantly impacting bowel movements.

Infections can also cause anal pain. These include bacterial, fungal, or sexually transmitted infections (STIs). Such infections lead to irritation, swelling, and pain, particularly noticeable during or after a bowel movement.

An anal abscess is a painful collection of pus near the anus, causing severe, throbbing pain, swelling, and redness. An anal fistula, often developing from a drained abscess, is an abnormal tunnel connecting the anal canal to the outside skin. Both cause discharge and intense pain, worsened during bowel movements.

When to Consult a Healthcare Provider

While many painful bowel movements resolve with home care, certain symptoms warrant professional medical attention. Consult a healthcare provider if pain is persistent or worsens. Significant or recurrent bleeding during or after bowel movements also requires evaluation.

Other signs include fever, chills, or unexplained fatigue with the pain. Unexplained weight loss or new, unresolved lumps and swelling around the anus also warrant medical advice. Changes in bowel habits not due to diet, or ineffective home remedies, indicate a need for professional assessment.

Relief and Prevention Strategies

Dietary changes are a primary step in managing and preventing painful bowel movements. Increasing fiber through fruits, vegetables, and whole grains adds bulk, promoting softer, easier passage. Adequate water consumption is equally important, softening stool and facilitating its movement.

Lifestyle adjustments also promote healthy bowel function. Regular physical activity stimulates intestinal contractions, aiding smoother bowel movements and reducing constipation. Respond promptly to the urge to defecate and avoid delaying. Adopting a comfortable posture, like using a footstool to elevate knees, can straighten the rectum and ease passage.

Proper hygiene reduces irritation. Gently clean the anal area with soft toilet paper, unscented wipes, or plain water after a bowel movement. Patting the area dry instead of rubbing prevents further irritation.

Over-the-counter remedies provide symptomatic relief. Stool softeners make bowel movements less painful by increasing water in the stool. Fiber supplements boost daily fiber intake. Topical creams alleviate pain, itching, and swelling associated with conditions like hemorrhoids.
