Anal Itching – What’s The Deal?
Daniel: I’m a 62 yr old male experiencing anal itching and I can’t figure out why. Diet is good with coffee my only real excess. Eliminations are regular, sometimes loose. What might be causing this and what can I do to correct it?
Dr. Chutkan: Daniel, anal itching is a common – and frustrating – problem, and people are often embarrassed to talk about it, so thank you for asking! You mention two things that might be clues to the cause of your anal itching – coffee and loose eliminations. Coffee is one of a number of foods that can cause irritation to the anus that’s manifest as itching. The mechanism might be a slight loosening of the anal sphincter that allows a small amount of stool to leak out and irritate the area. Other foods/beverages that can do this include soda, energy drinks, beer, chocolate, citrus, spicy foods and dairy. If you’re having more than a cup a day you might want to cut your caffeine consumption way down (or stop altogether!) and see if the itching improves.
Loose stools can also create itching from over-wiping. Be sure to avoid using any scented or pre-moistened wipes/products and instead, try using a little vaseline on the toilet paper to clean more effectively with less wiping. If you have access to a bidet, lukewarm water to rinse the area after gentle wiping can be soothing rather than irritating.
Some other things to think about that may be causing your anal itching:
- Fungal overgrowth, especially if you’ve recently been on antibiotics or keep damp clothing on after exercise.
- Anal fissures, which can result from constipation or be associated with more serious conditions like Crohn’s disease.
- Hemorrhoids, which can result from straining or frequent bowel movements.
- Stool leakage, or incomplete wiping, resulting in some residual stool in the area.
- Parasites like pinworm which often cause itching at night when the worms move to the anal area to lay their eggs.
- Irritation from synthetic fiber underwear.
- Sexually transmitted diseases (STDs) like genital warts.
In addition to trying some empiric fixes like cutting back on coffee and putting a little vaseline on the toilet paper, I’d recommend having a gastroenterologist take a look. Fissures, fungal overgrowth, hemorrhoids, anal irritation, and certain STDs can all be diagnosed with a rectal exam, and there are some simple stool tests to diagnose parasites like pinworm.
