Itching all over the body can be caused by multiple factors, including dry skin, allergic reactions, insect bites, skin conditions like eczema or psoriasis, and certain systemic illnesses such as liver disease, kidney disease, thyroid problems, or diabetes. It may also be due to medications, pregnancy, or nervous system issues. If the itching is severe, persistent, or accompanied by other symptoms, it is advised to seek medical attention for proper diagnosis and treatment.

Common Causes of Generalized Itching

• Dry skin, which can be caused by weather, aging, or use of soaps
• Allergies causing hives or contact dermatitis
• Skin conditions including eczema, psoriasis, or scabies
• Insect bites such as mosquitoes or mites
• Heat rash or irritation from clothing or chemicals

Serious Causes That Require Medical Evaluation

• Liver disease or kidney failure
• Thyroid disorders (both overactive and underactive)
• Blood disorders or cancers
• Nervous system diseases or psychiatric conditions
• Side effects of medications

What to Do

• Moisturize skin regularly and avoid irritants
• Use over-the-counter anti-itch creams for relief
• Keep skin cool and avoid scratching to prevent damage
• Consult a healthcare provider if itching is severe, widespread, or persistent, especially if accompanied by other health symptoms.
