Possible causes of anal itching include:

  • Personal care habits. Your skin care routine may include products or behaviors that irritate the skin. These include washing too much, washing too little, and using soap, moist wipes or toilet paper with dyes and perfumes.
  • Infections. Sexually transmitted infections may involve the anus and cause anal itching. Pinworms can cause persistent anal itching. Other parasites may cause similar itching. Yeast infections, which usually affect women, can also cause itching in the anal area.
  • Skin conditions. Sometimes anal itching is the result of a specific skin condition, such as psoriasis or contact dermatitis.
  • Other medical conditions. These include chronic diarrhea, hemorrhoids, anal tumors and diseases that affect the whole body, such as diabetes.
