Perianal dermatitis is inflammation of the skin around the anus. It causes stinging, itching, erosions, bleeding, redness and great discomfort.
Causes of perianal dermatitis
The most common cause of perianal dermatitis is bacterial overgrowth associated with food intolerance, often lactose, fructose or gluten.
On the other hand, scratching the area produces added superinfection and worsening of symptoms. In this situation, fungal colonization of the skin is frequent.
On other occasions, intestinal bacterial overgrowth is a good culture medium for the development of intestinal candida and secondary infection of the anal area.
Constipation and diarrhea also injure the anus, and bacterial infection of these erosions determines the development of perianal dermatitis.
In addition, if the patient with perianal dermatitis reports gas, distension of the abdomen, poor digestion, foul-smelling wind, bad breath, intestinal noises and variable diarrhea, it is advisable to start the diagnosis to rule out food intolerance as the cause of the problem.
In these cases, it is essential to visit a specialist in Proctology expert in food intolerances to study and diagnose the patient, usually through simple tests.
Many cases of worsening of hemorrhoids and appearance of anal fissure are due to intolerance to certain foods.
Once the intolerance is detected, a change in diet by eliminating the substance to which the patient is intolerant solves the problem.
