The majority of cases are caused by skin irritation from fecal soilage. In older people, or in anybody with diarrhea, seepage of fecal matter may occur. Also, as people grow older, anal skin becomes more irregular and harder to clean. People with hemorrhoids (which may trap small fecal particles) are more prone to itching.

At any age, not taking the time to wipe thoroughly may contribute to poor hygiene, which causes itching and irritation. Then, too, being overzealously hygienic, such as rubbing energetically with dry toilet paper, can injure the skin. Another precipitating factor may be the hard stools of constipation, which can irritate the anal area.

Once the itch starts, many factors can exacerbate it. Hot weather and sweating, tight clothes that compress the buttocks, and nonabsorbent nylon panty hose and underwear may make matters worse, as can activities such as walking, sitting-particularly prolonged sitting on a plastic seat, which hampers the evaporation of any sweat-and bike riding. Some experts think stress may also be a factor in anal itching.

Home Remedies for Anal Itching
Clean carefully. Meticulous, gentle cleaning provides relief. One option is to regularly use pre-moistened wipes. You can also wash the anal area gently-in a shower or bath or over the toilet-with soap and water. Take care to rinse thoroughly, then gently pat the area dry with a towel or cotton ball.

Control the itch. Corticoid lotions or creams can be effective if used for a short time. Avoid the "-caine" creams sold for topical relief, since they can further inflame sensitive skin.

Don’t scratch. It only causes additional irritation and invites infection.

Consider changing your toilet tissue. Use plain, unscented, non-colored tissues.

Eat foods high in fiber, such as cereals, fruits and vegetables. Consume prunes, spicy food, orange juice, figs, coffee and beer only in moderation.

Be prepared. When away from home, carry a few pre-moistened, individually packaged wipes-the kind you use for a baby.

Manage leakage. If you are bothered by leakage, wear a small cotton pad against the anal opening and change it frequently. Underwear should have a cotton crotch. Avoid tight clothing.

Don’t schedule long bike rides-at least until the problem is resolved. Also, avoid other activities that may cause excessive perspiration.
