Generalized Body Itching (Pruritus), Especially After Taking a Bath
Generalized body itching, particularly after bathing (often called aquagenic pruritus when triggered by water contact), is a sensation of itching affecting most or all parts of the body, usually without obvious skin rashes. It can be due to skin conditions, systemic diseases, environmental factors, or reactions to water, soaps, or temperature.
🌹Causes
Dry skin (Xerosis) – very common, worsened by hot water and harsh soaps.
Aquagenic pruritus – itching triggered by contact with water, regardless of temperature.
Allergic or irritant reactions – soaps, sponges, towels, detergents, antiseptics.
Hot water exposure – increases skin dryness and histamine release.
Skin conditions – eczema, atopic dermatitis, psoriasis, urticaria.
Systemic diseases:
Liver disease (e.g., cholestasis)
Kidney failure (uremia)
Diabetes mellitus
Thyroid disorders
Iron deficiency anemia
Blood disorders – e.g., polycythemia vera (classically causes itching after bath).
Infections – HIV, parasitic infestations.
Hormonal changes – pregnancy, menopause.
Medications – opioids, antimalarials, ACE inhibitors.
Psychogenic causes – anxiety, stress.
