The main complications of uremia include renal anemia, renal hypertension, and renal bone disease. Uremia is a disease in which the kidney’s excretory metabolic function decreases, metabolite retention occurs, and there is an imbalance of water, electrolyte and acid-base metabolism. Common complications are as follows. 1. Nephrogenic anemia, which is mainly caused by decreased secretion of erythropoietin after the decline of renal endocrine function. The main manifestations are weakness, shortness of breath, dizziness and so on. 2. Renal hypertension, most of the patients have different degrees of hypertension, mostly caused by water and sodium retention, activation of renin-angiotensin-aldosterone system or insufficient production of certain vasodilating factors. 3. Renal bone disease, because of endocrine dysfunction, insufficient active vitamin D, calcium and phosphorus metabolism disorders (often low calcium, high phosphorus), parathyroid hormone elevation. The main manifestations are bone pain, itchy skin, and susceptibility to fracture. There are many other complications of uremia, patients should visit regular regular hospitals, review blood routine, kidney function, electrolytes, parathyroid hormone, etc., and be guided to treatment by professional doctors who judge the situation according to the indicators.
