What should be done for generalized itching in the elderly?

In general, generalized itching in the elderly may be caused by factors such as dry skin, clothing friction, urticaria, eczema, or diabetic skin lesions. If the above conditions occur, it is recommended to seek medical attention at a正规 hospital and receive treatments such as general supportive care or medication under the guidance of a physician. Specific analyses are as follows:

1. Dry Skin

With aging, the sebaceous glands in elderly individuals gradually decline in function, leading to reduced sebum production. This may weaken the skin's barrier function and increase water evaporation, resulting in dry skin and consequently causing generalized itching. Daily use of moisturizing skincare products is necessary to prevent skin dryness.

2. Clothing Friction

The skin of older adults is more sensitive. Rough-textured or synthetic fabrics can easily generate static electricity and increase friction against the skin, potentially leading to widespread itching. It is advisable to wear comfortable, soft, and loose-fitting clothing to minimize irritation.

3. Urticaria

Urticaria may be triggered by drug allergies, infections, or other causes, possibly resulting in wheals (raised itchy rashes) over the entire body or localized areas, accompanied by symptoms such as itching and redness. Patients should follow medical advice and take medications such as cetirizine tablets, loratadine tablets, or dexamethasone tablets for treatment.

4. Eczema

Eczema may be induced by genetic factors, environmental changes, or immune system abnormalities. It can cause skin manifestations such as erythema, papules, and vesicles, which may lead to generalized pruritus, often accompanied by oozing or exudation. Under medical supervision, patients may use topical agents such as hydrocortisone cream, tacrolimus ointment, or oral loratadine capsules for management.

5. Diabetic Skin Lesions

Metabolic disturbances, genetic predisposition, and low immunity may contribute to diabetic skin complications. In elderly individuals with diabetes, elevated blood glucose levels increase glucose concentration in the bloodstream, directly stimulating peripheral nerve endings in the skin and causing itching. Symptoms may also include flaking and dryness. Under a doctor’s guidance, patients may use medications such as miconazole nitrate cream, ketoconazole cream, or metformin tablets for treatment.

Older adults should maintain proper skin hygiene and adequate moisturization, choose appropriate clothing materials, avoid excessive cleansing and exposure to hot water, and pay attention to overall health by preventing and managing chronic diseases to maintain healthy skin.
