What diseases should we be alert to when we have itching all over the body

The skin is the largest organ in our body. It plays an important role in defense and warmth retention, but it is also very fragile. Sometimes we find that our skin itches for no reason. Many people may think that it will be fine as long as we apply something to relieve the itching. But in fact, itching all over the body may very likely indicate that there is a disease inside the body. So what diseases should we be alert to when itching all over the body?

1. What diseases should you be alert to if you have itching all over your body?

1. Simple skin problems: There are two situations in which you feel itchy due to skin problems themselves.

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.

2. 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.

3. 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.

4. Gynecological inflammation If women find itching in the vulva, 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. Negative emotions such as depression, tension, irritability, etc. may cause local or systemic skin itching.

5. Lack of B vitamins can also easily cause skin itching.

Hepatobiliary diseases 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.

6. 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.

7. 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.
