The anus is the outlet for the rectum, and when itching occurs in this area, it can be severe, causing a strong urge to scratch. Not only is it annoying and uncomfortable, it can also be embarrassing. Most of the time the problem is nothing to worry about. Occasionally, it may be a sign of a serious medical condition, according to MayoClinic.com.
Bowel Incontinence
Loss of bowel control through small amounts of stool can cause anal itching, as can frequent diarrhea.
Washing Too Frequently
Washing too frequently or not completely rinsing off all the soap can irritate the anal area, resulting in itching. Using a harsh toilet paper or soap can aggravate the situation as well. To combat this, people can use a soft, cotton toilet paper moistened with warm water.
Too Much Moisture
Excessive moisture can come from sticky bowel movements and sweating. Applying a small dusting of talcum powder or cornstarch to the anus helps prevent moisture from forming.
Certain Foods
Some foods contain irritating chemicals that result in anal itching. These chemicals are typically found in spicy foods and hot sauces. Other foods may have a direct or indirect effect on the anus as they exit from the colon, including chocolate, tomatoes, alcohol and citrus fruits. Some caffeinated drinks, as well as milk, might cause diarrhea, which results in itching of the anus. Avoiding these foods may help the condition improve.
Parasites
Parasites such as pinworm can cause itching of the anus, especially in children. When the itching occurs, children have a tendency to scratch, leaving the eggs and parasites under their fingernails. They then eat, place their fingers in their mouth, or touch objects around the home, spreading the infection.
Poor Hygiene
Not washing hands after using the bathroom, not bathing on a regular basis and not wiping the anus completely or correctly all contribute to anal itching. Improving in these areas help prevent or completely eliminate anal itching.
