After getting uremia, some patients may experience hand numbness, which may be caused by uremia itself, or by combined vascular calcification, peripheral neuritis, carpal tunnel syndrome, etc. The specific situation needs to be analyzed.
1. Uremia: Due to the loss of kidney function, the body's metabolic products and excess water cannot be excreted, leading to increased concentrations of calcium, potassium, and phosphorus in the blood, resulting in electrolyte imbalance and causing hand numbness. In addition, when the kidneys excrete water, the renal tubules reabsorb water. If the excretion of water in uremia patients is insufficient, causing water retention in the body, which leads to increased blood volume and elevated blood pressure, it can also cause hand numbness.
2. Vascular calcification: Uremia patients often have vascular calcification, which is a manifestation of arteriosclerosis and also a pathophysiological process of uremia. After vascular calcification, patients are prone to vascular stenosis and occlusion, causing hand numbness.
3. Combined peripheral neuritis: Uremia patients often have combined peripheral neuritis. Due to the influence of toxins, it can lead to poor circulation of peripheral nerves, resulting in hand numbness, foot numbness, limb weakness, and other symptoms.
4. Combined carpal tunnel syndrome: After getting uremia, the patient's renal failure will lead to the accumulation of water and metabolic waste in the body. Excessive water can cause edema in the body. In addition, due to electrolyte imbalance, acid-base imbalance, and changes in hormone levels, it can also cause carpal tunnel syndrome. The increased pressure in the carpal tunnel compresses the median nerve, which can lead to hand numbness.
In addition to the above reasons, if the patient's arm is compressed while sleeping, it can also cause hand numbness. It is recommended that uremia patients pay attention to a reasonable diet and avoid consuming high-salt foods such as pickles. In addition, patients should rest, avoid overexertion, and ensure adequate sleep time.
