What Causes Generalized Itching?

Generalized pruritus (itching all over the body) is most commonly caused by an allergic reaction to allergens encountered during sleep, but it may also result from insect bites or poor personal hygiene—such as infrequent bathing over an extended period. Patients should consult a dermatologist at a reputable hospital for proper evaluation. Treatment, under medical supervision, typically includes oral antihistamines and topical corticosteroid ointments to relieve itching.
