Failing kidneys can play havoc with other parts of the body. Specific treatment of these associated problems may help ward off uremia and preserve whatever renal function remains. Sodium levels may drop if too much water is mistakenly given to counteract kidney failure. Hyperkalemia can lead to cardiac arrest if potassium levels aren't reduced without delay. Acidosis also may reach life-threatening proportions, especially if diarrhea occurs. Almost all patients with chronic renal failure have a bleeding tendency and anemia, with the hematocrit dipping as low as 20 percent. Over half have decreased tolerance to carbohydrares, although severe hyperglycemia is rare. Disorders of calcium metabolism also are common, ranging from asymptomatic hypocalcemia to osteomalacia. The kidneys' impaired filtration ability should be kept in mind when drugs are prescribed. Dosages may need to be cut to avoid an adverse reaction. |
