Why Are You Itching? Uncovering the Causes of Pruritus
Published: Nov 03, 2023
Itching can be more than skin deep. Discover the numerous conditions that can cause this persistent sensation.
Skin Disorders and Pruritus
Many dermatologic conditions, such as eczema, psoriasis, and urticaria, present with itching as a primary symptom. These conditions often have visible signs, like redness or scaling, that help pinpoint the cause of the itch.
Systemic Causes of Itching
Systemic diseases like kidney failure, liver disease, and certain cancers can cause generalized itching without any visible skin changes. These conditions often require a comprehensive evaluation to identify the root cause.
Neurologic and Psychogenic Itch
Itching can also stem from nerve damage or psychological disorders. Neuropathic itch arises from nerve dysfunction, while psychogenic itch may be linked to stress or psychiatric conditions.
