Causes of itchy bottom

As itchy bottom is a symptom rather than a condition itself, many cases have an underlying cause, for example:
-a bacterial infection – such as those that cause streptococcal infections
-a skin condition – such as atopic eczema, where the skin becomes red, dry and flaky
-haemorrhoids (piles) – swellings that contain enlarged and swollen blood vessels in and around the anus

In children, an itchy bottom is often caused by threadworms.

But not all cases of itchy bottom have an identifiable cause.

An itchy bottom can be made worse by:
-heat
-woolen clothing or blankets
-moisture
-soiling yourself
-stress or anxiety
