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

Pruritus is a very common skin disease in the human body, which is very uncomfortable once it occurs. Especially when the skin all over the body is itchy, it itches everywhere and it itches wherever you scratch. In severe cases, scratching it will cause more serious consequences. The human skin is exposed to more outside air, and there are also more bacteria in the air, so symptoms of skin itching will occur. So what disease should you be alert to if your skin all over your body is itchy?

In autumn and winter, the skin is relatively dry and prone to pruritus. In fact, there are some potential diseases associated with pruritus. We need to be alert to the following 9 diseases.

1. Kidney disease: Kidney disease is generally referred to as kidney disease or nephropathy. There are many types of kidney diseases, the most common of which is chronic kidney disease. Generally, patients with chronic kidney disease will have varying degrees of skin itching symptoms.

2. Hepatobiliary diseases: In patients with hepatobiliary diseases, especially when the bile duct is obstructed, bile salts are deposited in the skin, stimulating nerve endings and causing skin itching. Some pregnant women experience systemic itching three months after pregnancy, which disappears naturally after delivery. This is also related to intrahepatic cholestasis.

3. Malignant tumor disease: Generalized itching may be an early symptom or the first symptom of mycosis fungoides and Hodgkin's lymphoma. Other diseases such as visceral malignant tumors and leukemia can also cause generalized itching. In such patients, pruritus may disappear after tumor removal, but may recur when the tumor recurs.

4. Gynecological and obstetric diseases: If women have menstrual disorders, gynecological inflammation and other diseases, most of them will be accompanied by local or systemic itching.

5. Endocrine diseases: Diabetes, hyperthyroidism and hypothyroidism can all cause skin itching.

6. Neuropsychiatric diseases: Spine, spinal cord tumors or tuberculosis may cause periodic itching. Brain tumor lesions infiltrating the bottom of the fourth ventricle can cause severe itching in the nostrils. Brain tumor patients may develop systemic itching in the late stage. Neurasthenia and certain mental illnesses, especially depressive psychosis, can cause or aggravate itching. Delusional parasitosis is the most typical case.

7. Blood system diseases: People with iron deficiency anemia and polycythemia vera may experience skin itching.

8. Infectious diseases: fungal, bacterial, viral and other infections can cause local or systemic itching symptoms.

9. Drug-induced pruritus: Some people may be allergic to certain drugs, which may cause skin itching.
