Introduction
Dry and itchy skin can be caused by various factors such as dryness, nutritional deficiencies, medication side effects, allergies, or hyperthyroidism. It is recommended to seek medical attention promptly and receive symptomatic treatment under a doctor's guidance. In daily life, it is advisable to consume more foods rich in protein, multiple vitamins, minerals, and other nutrients—such as eggs, lean meat, tomatoes, apples, etc.—to help replenish the body's energy needs.
Skin dryness and itching are generally caused by factors such as dryness, nutritional deficiencies, drug side effects, allergies, and hyperthyroidism. It is recommended to seek timely medical attention and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:
1. Dryness
Dry skin may become thin and fragile, making nerve endings more susceptible to irritation. When the skin is stimulated, itching may occur. This can be alleviated by drinking plenty of water, using a humidifier, and applying moisturizing lotions or creams.
2. Nutritional Deficiency
A lack of certain essential trace elements and vitamins can affect skin health, impairing both the sensory function of nerve endings and the skin’s ability to repair itself, leading to symptoms such as itchy, dry, and rough skin. Patients may take medications such as mecobalamin tablets, oryzanol tablets, and vitamin B6 tablets as directed by a physician for relief.
3. Drug Side Effects
If a patient is taking medication, certain drug components may cause blood vessel dilation, increasing skin sensitivity and resulting in itching. Symptoms may be relieved by switching medications or adjusting dosages.
4. Allergy
Allergy is an excessive immune response by the body's immune system to allergens. If a patient comes into contact with allergens such as pollen, dust mites, or pet dander, an allergic reaction may occur, causing skin itching. Patients may be treated with antihistamines such as loratadine tablets, levocetirizine hydrochloride tablets, or ebastine tablets as prescribed by a doctor.
5. Hyperthyroidism
Hyperthyroidism refers to the overproduction of thyroid hormones. During episodes of the condition, hair follicle function may be affected, leading to folliculitis or excessive sweating, both of which can cause skin itching. Patients may be treated under medical supervision with medications such as Jiaxiong Ling tablets, methimazole tablets, or propylthiouracil tablets.
In daily life, it is recommended to consume foods rich in protein, various vitamins, and minerals—such as eggs, lean meat, tomatoes, and apples—to supplement the body's energy needs and help maintain overall health.
