Burning after diarrhea in the anus( burning diarrhea), why burn?

In itself, a disorder of the stool, regardless of the causes of it caused, is an unpleasant phenomenon. And if, in addition, diarrhea is accompanied by a burning sensation in the circumanus space, the level of discomfort rises many times. In general, the problem of itching and burning in the anus is quite common. And the main reason for this - elementary failure to comply with sanitary conditions or serious diseases of internal organs.

Burning after diarrhea is characteristic:

  • when there are parasites in the intestines;
  • intestinal dysbiosis;
  • giardiasis;
  • use of acute or unusual food.

Depending on the causes that caused diarrhea, burning in the anus is of a different nature. The most common infection is intestinal parasites( enterobiosis).Parasites, better known as pinworms, live in the rectum and, without creating painful sensations to the person, at the same time give the sensation of unbearable itching in the anus. Basically, infection occurs by the oral route. Seeking to alleviate the itching in the anus, a person combs this place, and brings the pinworm eggs under his nails. In the future, taking food with unwashed hands, eggs are put into the mouth by the person himself. Especially this way of infection is typical for young children. It is also possible to transmit parasites through a handshake. Infection with parasites also occurs through contact with animals, when eggs enter the intestine and, developing to worms, lay eggs again.

With a lot of pinworms, itching in the anus becomes unbearable and is accompanied not only by diarrhea, which can be with mucus, but also with severe pain in the abdomen, bedwetting. It should be noted that only those eggs of parasites that are not in the feces are active, but are deposited near the anus. Therefore, the main measures to eliminate diarrhea and burning in the anus are hygienic in nature and consist in careful observance of personal hygiene, do not use unwashed vegetables and fruits, water from unknown sources. It is recommended to wear closely fitting underwear of white color, changing it daily. With regard to drug treatment, it is carried out on the recommendation of a doctor after conducting laboratory tests and establishing the nature of helminths.

Burning diarrhea can indicate the development of Giardiasis. The causative agents of human lambliasis are intestinal lamblia, which cover large surfaces of intestinal walls, disrupt its motility, destabilize the secretory activity of the intestine by absorbing fats and carbohydrates. Irritating the epithelium of the duodenum, lamblia contribute to mechanical irritation, burning, and have a strong toxic effect on the human body.

The main source of penetration of parasites into the intestine is the person himself, who, along with feces, has viable invasive lamblia cysts. The lambliasis is transmitted by the fecal-oral route. In children's preschool institutions, the main sources of infection are dirty hands, contaminated household items( door handles, pots, etc.).The source of contamination can be soil contaminated by human and animal feces. In some countries, outbreaks of Giardiasis were triggered, provoked by drinking water in case of accidents at treatment plants. A characteristic sign of Giardia is the aggravation of burning late at night or at night during sleep, when the females crawl out to lay eggs.

Itching and burning in the anus after diarrhea are typical for intestinal dysbacteriosis. Constant diarrhea, which is the main factor in the imbalance of the intestinal microflora in this case, is the reason why, after diarrhea, burns in the anus. As you know, the gastrointestinal microflora, which plays a huge role in the normal functioning of the body, contains over half a thousand different kinds of microorganisms. With a normal ratio of beneficial and harmful microorganisms, the pathogenic effect of the latter is not manifested. However, under certain conditions and pathologies, the equilibrium is disrupted and dysbacteriosis develops, the most severe form of which occurs when staphylococcus is associated with other microbes. In the treatment of dysbiosis, it should be noted that this disease is a secondary pathology and its elimination is necessary for success in the treatment of the underlying disease.

Diarrhea caused by a nerve disorder increases the sensitivity of the skin near the anus. As a result, after each trip to the toilet, the strength of the irritation of the delicate skin in this place increases, and the burning sensation in the anus becomes very sharp. Sensation of burning diarrhea accompanies acts of defecation in the disorder of stool caused by the use of spicy food. Contained in diarrhea undigested remnants of spicy, salty foods, additionally irritate the crotch and cause an acute burning sensation.
