Itchy skin, or pruritus, is a common sensation that can be caused by a variety of conditions. Itching can be divided into two main types: localized itching which affects only one area or spot and generalized itching which affects the entire body.

Common causes of itchy skin include allergies, insect bites, contact dermatitis (which occurs when your skin comes into direct contact with irritants such as chemicals), environmental temperature changes, infection and medical conditions (such as thyroid disease). Other causes of itchiness are stress-related psychological disorders like anxiety and depression; hormonal imbalances; dry skin due to inadequate hydration; certain medications including antibiotics and chemotherapy drugs; radiation therapy for cancer treatment; liver disease; kidney failure; certain cancers such as lymphoma or leukemia.

There are a few things you can do to help relieve itchy skin. An over-the-counter topical antihistamine cream may provide relief if the cause is an allergic reaction. You should also keep your skin clean and moisturized by using gentle soaps without fragrances or dyes. Emollients such as petroleum jelly have been known to reduce itchiness in some people. Additionally, taking a hot shower with oatmeal lotion may help reduce redness and inflammation associated with itchy skin flare ups from allergies or other triggers mentioned above. In cases of severe itching that does not respond to these measures visit your doctor for advice on further treatment options depending on what diagnosis is reached upon evaluation of possible underlying factors causing this symptom.
