Anal Eczema (Anal Itching)

Anal itching is caused by the irritation of the skin at the exit of the rectum, known as the anus, accompanied by the desire to scratch. Although itching may be a reaction to chemicals in the stool, it often implies that there is inflammation of the anal area. 

The intensity of anal itching and the amount of inflammation increases from the direct trauma of scratching and the presence of moisture. At its most intense, anal itching causes intolerable discomfort that often is described as burning and soreness.

What Causes Anal Itching?

  • Irritants: High levels of moisture due to constipation or long-term and chronic diarrhea can irritate the skin. In addition, your skin care routine including products or behaviours may irritate your anal area, ie. soaps, moist wipes, washing aggressively and with hot water.
  • Food: Certain foods ingested such as spices, hot sauces and peppers may induce anal itching.
  • Infections: In addition to irritants, anal itching could be a sign of sexually transmitted infections or diseases, pinworms, or yeast infections. Antibiotics used to treat yeast infections are also known to cause anal itching.
  • Skin Conditions: Anal itching can sometimes be the result of a specific skin condition like psoriasis or contact dermatitis.
  • Underlying Health Conditions: Diabetes, thyroid disease, hemorrhoids, anal tumours, or Chron’s disease.
