Itchy skin, also known as pruritus, is an irritating and uncontrollable sensation that makes you want to scratch to relieve the feeling. The possible causes for itchiness range from internal illnesses, such as kidney or liver disease, to skin rashes, allergies, and dermatitis.
It’s important to see a doctor for itchiness if the cause isn’t obvious. A doctor can find the underlying cause and provide treatments for relief. Several home remedies such as over-the-counter creams and moisturizers work well for itching.
Causes of Itching
Itchiness can be generalized (all over the body) or localized to one small region or spot. The possible causes are numerous and varied. It may be a result of something very serious, such as kidney failure or diabetes (though uncommon), or can come from something less severe, such as dry skin or insect bites (more likely).
