What causes itchy skin after bathing?

Digestive system diseases

Hemorrhoids, anal fistula, intestinal parasitic diseases, etc. can often cause anal skin itching. Hepatobiliary diseases, whether obstructive jaundice, intrahepatic jaundice, hemolytic jaundice, or liver damage without jaundice, can cause skin itching, which is related to the retention of bile acid, histamine, etc. and acidosis. Pregnant women before delivery may also experience skin itching. In addition to the metabolism of estrogen in the liver, another important reason may be cholestasis, but this itching will disappear on its own after delivery.

Urogenital diseases

Some people suffer from chronic nephritis and renal insufficiency, which often cause systemic skin itching due to factors such as increased urea and protein derivatives in the blood, calcium-phosphorus metabolism disorders, increased parathyroid hormone secretion and increased methanol content in the epidermis. Vulvar itching can also occur in women due to menstrual disorders, ovarian lesions, vaginal trichomoniasis or fungal infections.

Endocrine system diseases

Itchy skin in diabetic patients may be due to increased blood sugar, reduced body defense against germs, susceptibility to bacterial and fungal infections, and dry skin. Skin itching caused by thyroid disease is not only seen in people with hyperthyroidism, but also often occurs in patients with hypothyroidism.

Blood system diseases

Patients with polycythemia vera may experience systemic or localized skin itching, which often worsens in the summer and can be aggravated by taking a warm bath. According to foreign reports, about 13% of male patients with iron deficiency anemia experience itching, and 7% of female patients experience itching.
