What causes itchy skin?

Itchy skin is a common condition for many people in daily life. There are many reasons for itchy skin, which may be caused by skin allergies, skin diseases such as papules and dermatitis, or mosquito bites. When faced with the situation of itchy skin, people need to understand the cause and prescribe the right medicine to cure it. The following is a detailed introduction to the causes of itchy skin.

There are several situations. One situation is that simple dryness causes an itch. You may have noticed that the elderly are more prone to itching, sometimes itching here and sometimes itching there. Many cases of skin itching in the elderly are caused by simple dryness. As people age, their skin's ability to retain moisture becomes weaker and weaker, and the skin becomes dry and flaky. If the liver itself can cause itching, then we can treat this type of itching by reducing washing, reducing the use of alkaline detergents, avoiding excessive scrubbing, and not washing with overheated water. Just use some moisturizer appropriately.

This is simply caused by dryness. Then there are some disease states that cause itching. There are many types of diseases, the most important of which are eczema or atopic dermatitis. This type of patient has a specific system. His skin itself is dry, but it is often accompanied by some erythema, papules, and some other lesions. This type of patient needs to combine some medications and then use moisturizers, which can also achieve good results. Others are some common ones, such as mosquito bites can also cause itching, right? Psoriasis may also cause itching, but the itching is generally not particularly prominent, so it can be treated symptomatically.

Treatment and care:

(1) Oral administration: 1/2 capsule of levocetirizine hydrochloride capsule, taken once in the morning; 1 tablet of chlorpheniramine tablet, taken once at night before going to bed; (2) Topical application: Apply a small amount of medical glycerin to the skin with warm water, once a day. The ratio is 1:20. 3. Do not take a bath too often, generally 2-3 times a week is enough. If you bathe too frequently, a large amount of sebum film will be washed away (especially when using detergents with strong alkaline properties). When the skin secretes relatively insufficient sebum, it will cause the skin to become dry and rough, produce desquamation and cause skin itching. If you must wash every day, try not to use toiletries or use children's shower gel. In addition, the water temperature for bathing should not be too high, generally around 30-35 degrees is enough.
