Why are my arms and calves itchy

Itching of arms and legs is a very common disease. The main causes of this disease are eczema or neurodermatitis. If it is caused by eczema, you must pay attention to a light diet and do not eat too much spicy and irritating food. If the itching is severe, you need to be careful that it may be pruritus. In this case, do not scratch with your hands, otherwise it will cause infection.

What causes itchy skin symptoms?

1. The cause of skin pruritus is still unclear. It is generally believed to be related to certain diseases, such as diabetes, liver disease, kidney disease, etc.; it is also related to some external stimulation factors, such as cold, warmth, chemical fiber fabrics, etc.

2. Excessive bile acid concentration

When the concentration of bile acid in the blood increases, it will be deposited in the skin, causing severe skin itching. Therefore, when your skin becomes itchy and yellow, you should go to the hospital to check your liver and gallbladder to see if you have gallstones.

3. Excessive calcium and phosphorus levels in the blood Excessive calcium and phosphorus concentrations in the blood can also cause itchy skin. If your skin is dry at this time and you have frequent urination, urgency, 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 the increase of urea toxins and protein derivatives in the blood.

4. Endocrine disorders

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

5. 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.

6. Patients with certain lymphatic system tumors such as myeloid granuloma, Hodgkin's disease, or myeloproliferative diseases often suffer from systemic itching.

Therefore, when skin itching is accompanied by other symptoms, you must not take it lightly. Don't "treat the head for a headache and the foot for a foot pain". It's best to go to the hospital to find out the cause and prescribe the right medicine.
