Excess humidity

If you want to know why your anus becomes itchy at night you have to keep in mind that there are many causes that can promote this situation and, among all of them, developing excess moisture in the area is a common cause of this itchiness.

Building up too much moisture in the anal area can be due to perspiration or because the area has not been properly dried after rinsing or showering; another possibility is that, after fecal deposition, you may not have cleaned the area properly and, therefore, the area remains moist and fecal matter may still linger on the area.

All these conditions can cause the area of the skin around the anus to become irritated and, therefore, you feel intense itching that you can only relieve by scratching. However, you should be very careful because this area is very weak and can easily tear causing wounds, slight bleeding or swelling.

Itchy feeling due to intestinal worms

One of the most frequent causes of itching in the anus is the presence of worms, which are technically known as "pinworms" or intestinal worms. Enterobius vermicularis is a type of parasite that lives in our body and is around 1 centimeter in length. They live in the rectal area, right at the end of our large intestine and, for most of their life, are curled up on themselves.

But why do we have worms in our body? Because we introduce their eggs by eating food or drinks that may be contaminated or due to putting our hand close to our mouth when it's dirty.

Its lifespan in our body is of 15 to 45 days and it is an infection that is very common in children between 5 to 10 years because they play in the street, put objects in the mouth, etc. But adults can also have worms, and these produce strong itching inside the anus, especially when night falls.

In this other article we tell you how to treat intestinal worms so you can get rid of them from you body and be able to go back to sleeping all night.

The Importance of your diet

Nocturnal itching of the anus may also be due to the way you eat. Keep in mind that there are some products that can be irritating and therefore create a buildup of toxins in our intestines, create a bigger alteration than usual and therefore may have a side effect that translates into anal itching.

What foods can cause itching in the anus? Here are the most frequent products:

  • Alcoholic beverages: especially beer or wine
  • Caffeinated beverages: coffee, soft drinks, tea, etc.
  • Dairy products
  • Candy and sugary products: especially chocolate
  • Sauces and fatty foods

This does not mean that everyone who eats this type of food gets an itchy anus, but it does mean that if you increase the consumption of these products you may experience a discomfort in the area because your digestive and intestinal system is altered.
