What physical diseases should we be wary of when itching the skin

Under normal circumstances, our skin will not show any discomfort symptoms. If itching symptoms occur, it is mostly a problem with the skin. At this time, you should pay attention to it, promptly understand the factors that cause your skin itching, and seek treatment in time to avoid serious damage to the body. So, what physical diseases should you be alert to when itching your skin? Let’s take a look.

Simple skin problems. There are two situations in which you feel itchy due to skin problems. Glenn Gisler said. One is non-primary skin damage, which is mostly caused by lack of moisture in the skin. Just like now in the dry winter, many people feel dry, itchy and peeling skin. The other is that the skin itself is sick. Skin diseases such as dermatitis, eczema, and psoriasis are mostly accompanied by itching.

Skin degeneration in middle-aged and elderly people. The skin of middle-aged and elderly people shrinks and becomes thinner, the water content decreases, and the secretion of sebaceous glands and sweat glands decreases, causing the skin to lose its lubricating and protective function and appear dry. In cold seasons, the dry climate makes the skin rough and even causes peeling of the epidermis, making the nerve endings in the skin more easily irritated and itchy. This is the reason why many elderly people suffer from itching.

allergy. Professor Liu Guanghui, chief physician of the Department of Allergy at Wuhan Tongji Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology, said: One-third of patients who visit the Allergy Department clinically have symptoms of itchy skin. Allergies to food, pollen, dust mites, etc., and contact with certain chemicals may cause allergies, making the skin feel itchy. This type of itching usually gets better after you stop coming into contact with the allergen.

Gynecological inflammation. If women find that their vulva is itchy, they should check for gynecological inflammation such as Trichomonas or Candida albicans infection. Surveys show that 73% of women experience local skin itching during menstruation, which may be related to poor quality sanitary napkins or overly tight clothing.

Emotionally tense. Negative emotions such as depression, tension, and irritability may cause local or systemic skin itching. A lack of B vitamins can also easily cause skin itching.

Hepatobiliary diseases. Hu Liming, deputy chief physician of the Department of Gastroenterology at the Oriental Hospital Affiliated to Beijing University of Chinese Medicine, said: Many systemic diseases can also cause skin itching. Studies have shown that approximately 40%-60% of patients with hepatobiliary diseases will experience skin itching when they experience liver discomfort, abnormal liver function, or jaundice.

diabetes. The incidence of skin itching in diabetic patients is as high as 15%-35%. About 10% of early patients will experience systemic or local skin itching, which is relatively stubborn, with the most severe symptoms in the vulva or anus.

Abnormal thyroid function. Whether it is hyperthyroidism or hypothyroidism, itchy skin may occur, but the itching caused by hyperthyroidism usually develops slowly, the skin is often dry, and it will worsen in winter.

Malignant tumor. Some tumors may be accompanied by itchy skin, such as cancer of the lymphatic system, stomach, intestine, liver, ovary and prostate. This kind of itching caused by tumors is mostly stubborn. If you have itching on your body for a long time without any reason, you need to pay attention to it.
