Many people who have chronic kidney disease don't know it, because the early signs can be very subtle. It can take many years to go from chronic kidney disease (CKD) to kidney failure. Some people with CKD live out their lives without ever reaching kidney failure.However, for people at any stage of kidney disease, knowledge is power. Knowing the symptoms of kidney disease can help you get the treatment you need to feel your best. If you or someone you know has one or more of the following symptoms of kidney disease, or you are worried about kidney problems, see a doctor for blood and urine tests. Remember, many of the symptoms can be due to reasons other than kidney disease.Healthy kidneys clean your blood by removing excess fluid, minerals and wastes. They also make hormones that keep your bones strong and your blood healthy. But if the kidneys are damaged, they don't work properly. Harmful wastes can build up in your body. Your blood pressure may rise. Your body may retain excess fluid and not make enough red blood cells. This is called kidney failure.If your kidneys fail, you need treatment to replace the work they normally do. The treatment options are dialysis or a kidney transplant. Each treatment has benefits and drawbacks. No matter which treatment you choose, you'll need to make some changes in your life, including how you eat and plan your activities. But with the help of healthcare providers, family and friends, most people with kidney failure can lead full and active lives.
