Defecation :

Expelling of fecal particles via rectum is known as Defecation. Bowel movement can occur few times a day for some people and few times in a week for some others. Muscular contraction occurs in the walls of the colon so that fecal particles can easily move through the digestive tract into the rectum. Defecation is the last stage of digestion through which unabsorbed food is expelled from the body.

Burning Anus Causes :

Burning sensation in the anus can be caused by many factors.

  • Eating spicy foods :

Some people may experience burning anus after eating in a restaurant previous night. Taking too much of spicy items that contain chilli and peppers can spoil the normal balance of the stomach. Normally the spicy item will get neutralized in the gut or stomach before reaching the intestine. If not, spicy foods can irritate the soft mucosal lining of the intestine as well as rectum leading to burning anus. For many cases burning sensation is felt immediately after passing stool. This is due to the effect of spicy foods.

  • Over cleaning :

Excess of wiping of the anus can disturb the normal balance causing pruritis ani or itchy anus. This action can cause inflammation of the soft lining of the rectum which drives one to scratch it. Repeated scratching of the area will cause burning anus.

  • Poor hygiene :

If you are not cleaning the anus region properly after using toilet you are likely to develop an infection. The reason is simple. You are expelling millions of bacteria via feces and when you are not cleaning/wiping the area powerful bacteria remains there causing irritation and itching. In the long run it may lead to burning anus and skin infections.

  • Constipation :

Piles (hemorrhoids) often occur due to chronic constipation. Many men prefer to take extra time for passing stool by voluntarily pushing it out. This can damage the soft skin of the rectum gradually leading to piles. Stools are usually semi-solid in nature so that it can be pushed out easily. But for some reasons you are postponing the act of expelling feces, the stool particles get hardened inside and the next time you use the toilet it has to literally tear its way out. Repeated constipation can cause piles and burning anus. Hemorrhoids can also cause pain and discomfort throughout the day.

  • Fissures :

Fissure can also cause burning pain in the anus. Due to chronic constipation the stool hardens and causes minute tears in the anus region leading to anal fissure. This condition can also cause rectal bleeding and anal itching not only after bowel movement but even afterwards.

  • Incontinence :

This condition is exactly opposite to constipation. Here the person will not be able to control the bowel movement till he/she reaches the toilet and in many cases they would wet their pants resulting in fecal incontinence. This is also called impairment of bowel control. Here again particles of feces will be retained in the anus for long time resulting in burning pain. More women than men are likely to develop fecal incontinence. And elderly people would have this problem frequently since the nerves that control and retain bowels in the rectum would not function properly on aging.

  • Other Diseases :

Severe diseases like inflammatory bowel disease, irritable bowel syndrome and any problem in gastroenteritis can cause burning anus and itching.
