What causes body itching?

Many reasons may cause itching in the body, so symptomatic treatment is needed according to the situation. Diseases such as diabetes, liver disease, kidney disease, etc. will cause this symptom in patients, and some are caused by skin allergies.

High levels of calcium and phosphorus in the blood

Excessive calcium and phosphorus concentrations in the blood can also cause itchy skin. If your skin is a little dry at this time and you have frequent urination, urgent urination, back pain, or even watery urine or little urine, you should consider the possibility of kidney disease. When patients with chronic nephritis enter the uremia stage, they often suffer from systemic skin itching due to increased levels of urea toxins and protein derivatives in the blood.

Endocrine disorders

For example, patients with hyperthyroidism have faster blood circulation in the skin and higher skin temperature, which causes itchy skin, especially after sleeping. Diabetic patients have increased blood sugar, which reduces the body's ability to defend against pathogens and makes them more susceptible to bacterial and fungal infections, which can also cause itchy skin.

Central nervous system diseases

Patients with neurasthenia and cerebral arteriosclerosis often experience paroxysmal itching; patients with brain tumors often experience severe and persistent itching when the lesions infiltrate the bottom of the ventricles, and this itching is limited to the nostrils.

Certain lymphatic system tumors

People with myeloproliferative diseases such as granulomatous granuloma, Hodgkin's disease, etc., often have systemic itch.

Therefore, when the skin is itchy and accompanied by other symptoms, you must never take it lightly. Don't treat the symptoms without addressing the cause. It is best to go to the hospital to find out the cause and prescribe the right medicine.
