When the kidneys are injured, they do not function properly. This might occur as a result of another medical condition, such as diabetes. Chronic renal failure refers to a decline in kidney function that occurs over a prolonged period of time. You may not be aware of any signs of acute renal failure. In fact, many people are diagnosed with it after experiencing symptoms of another problem, such as high blood pressure or heart failure. The following are some of the more common problems associated with kidney failure. Anemia: If you have kidney failure, you are at risk for developing anemia because your body is no longer able to remove red blood cells from your system. This risk can be reduced by receiving adequate amounts of iron through your diet and supplements. If you are undergoing dialysis treatment, your doctor may recommend that you receive intravenous (IV) injections of iron. Bone disease: If you do not take care of yourself by getting enough calcium in your diet and supplementing your urine waste product, you will develop bone disease. This happens when you lose too much calcium through your urine. Your bones become weak and vulnerable to damage due to constant removal of calcium through your urine. This can lead to serious complications including pain when moving muscles, nerves, or joints, fractures, and increased risk for cardiovascular illness or infection. Chronic lung disease: People who have chronic kidney disease are at risk for developing chronic lung diseases such as emphysema and asthma.
