Generalized Itching Overview

Generalized itching or “general pruritus” or “itching all over” has a variety of causes. Acute skin conditions such as allergic dermatitis may indicate a reaction to a substance (e.g. hives, urticaria, contact dermatitis). Almost any type of skin rash may cause itch. Chronic skin disorders such as eczema or psoriasis cause itch, as may any disorder that causes chronic skin rash.

Various types of systemic disorders can also affect the skin such as diabetes, thyroid disease, kidney failure, liver disease, polycythemia, leukemia, lymphoma and many others. Jaundice from hepatitis and other types of liver disease may cause widespread itching (usually with other symptoms such as yellow skin).
