Itching on the body indicates ten kinds of diseases

Everyone has experienced "itching". Sometimes it makes people laugh, and sometimes it makes people cry. More than 100 years ago, American psychologists Stanley Hall and Arthur Allyn first defined "itch". Itch can be divided into two types: one is "happy itch", which is caused by stimulation of sensitive parts such as the soles of the feet and armpits, accompanied by unstoppable laughter. Parents and babies first establish an intimate relationship through this kind of itch; the other is "annoying itch", which feels like something small is crawling on the skin. People can't help but scratch to relieve the itch. Insect bites, dry skin, fungal infections, cardiovascular and cerebrovascular diseases, etc. can all cause this kind of itch.

allergy

"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, resulting in itchy skin. 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.

Emotional tension

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

"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 have liver discomfort, abnormal liver function, and 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.

Thyroid dysfunction

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.
