The Mayo Clinic provides a list of several remedies to combat itchy skin, including using a high-quality moisturizing lotion daily, applying anti-itch cream to the affected area, taking lukewarm baths and showers, adding baking soda or oatmeal to baths, using mild, fragrance-free soaps and laundry detergents, and reducing stress with counseling, yoga or meditation. WebMD recommends moisturizing skin from the inside out by supplementing with fish and flaxseed oils.
There are several possible causes of itchy, irritated skin, according to the Mayo Clinic. Dry skin is a common cause of itchy skin and can result from environmental factors, central heating and air conditioning, and bathing too frequently. Skin conditions such as eczema and psoriasis also cause itchy skin, as do diseases and disorders such as diabetes, liver disease and multiple sclerosis. Pregnancy, reactions to prescription drugs and food allergies are also risk factors for itchy skin.
For prolonged, severe skin itching that has no explanation, does not go away with home treatment or is accompanied by other unexplained symptoms, the National Institute of Health recommends consulting a medical professional, as this type of severe itching may be indicative of a more serious underlying condition. During an examination, a doctor or nurse may ask questions about the patient's symptoms and medical history to rule out probable causes.
