Itchy palms can be caused by psoriasis, dry skin, eczema, scabies, diabetes or allergies. A doctor should be consulted to diagnose the condition properly, says WebMD.
Psoriasis occurs when skin cells grow rapidly and stack onto the skin's surface. Psoriasis generally runs in families. In addition to itchy palms, symptoms include patches of red skin, painful or stiff joints, soreness of the affected area, and bumps filled with puss, according to WebMD.
Dry skin is often caused by winter weather or excessive scrubbing, says WebMD.
Eczema describes several conditions that inflame the skin. A specific type, dyshidrotic dermatitis, only affects the hands and feet. Its symptoms include clear blisters, cracked skin and scaly skin, reports WebMD.
Scabies is caused by a mite that burrows into the top layer of a person's skin and lays eggs. It typically spreads in crowded areas where skin-to-skin contact is frequent and happens for a long time. It also causes pimply rashes, tiny blisters and scales, sores, and gray or white burrows in the skin, says WebMD.
A diagnosis of diabetes often follows a skin problem. The condition eruptive xanthomatosis causes itchy hands and feet. It is caused when a patient is not in control of his diabetes. The itching usually recedes when the diabetes is well-managed, claims WebMD.
Itchy palms can be a symptom of an allergic reaction. Additional symptoms can include rashes, hives and blisters, reports WebMD.
