What is chronic kidney disease (CKD)?
Click here to watch a brief video about CKD
Healthy kidneys function to remove extra water and waste from the blood, help control blood pressure, keep body chemicals in balance, keep bones strong, tell your body to make red blood cells and help children grow normally. Chronic kidney disease (CKD) occurs when kidneys are no longer able to clean toxins and waste product from the blood and perform their functions to full capacity. This can happen suddenly or over time.
What is acute renal failure?
“Renal” means related to the kidneys. “Acute” means sudden. So acute renal failure means the kidneys have failed suddenly, often due to a toxin (a drug allergy or poison) or severe blood loss or trauma. Dialysis is used to clean the blood and give the kidneys a rest. If the cause is treated, the kidneys may be able to recover some or all of their function.
What are the main causes of kidney disease?
Diabetes is the number one cause of kidney disease, responsible for about 40 percent of all kidney failure. High blood pressure is the second cause, responsible for about 25 percent. Another form of kidney disease is glomerulonephritis, a general term for many types of kidney inflammation. Genetic diseases, autoimmune diseases, birth defects and other problems can also cause kidney disease.
I have diabetes. Will my kidneys fail?
Diabetes is a risk factor for kidney disease, but this does not mean your kidneys will fail. You can care for your kidneys by controlling your blood sugar and getting regular microalbumin urine tests to catch any early signs that your diabetes may be affecting your kidneys. Even if you develop diabetic kidney disease, you can work with your doctor to keep your kidneys functioning as long as possible.
Can I catch kidney disease from someone who has it?
No. Kidney disease is not contagious. You cannot catch it from someone. Most kidney disease is caused by diabetes and high blood pressure, conditions that can run in families. If you are a family member of someone who has diabetes, high blood pressure or kidney disease, it is a good idea to ask your doctor to check your blood pressure and kidney function at your checkup.
What are kidney stones?
A kidney stone occurs when substances in the urine form crystals. Kidney stones can be large or small. Large ones can damage the kidneys; small ones may be able to pass in the urine. Because crystals have sharp edges, passing even small stones can be very painful. Treatment depends on what the stones are made of.
What is PTH?
Parathyroid hormone (PTH) is produced by several small, bean-like parathyroid glands in your neck. Its “job” is to tell your bones to release calcium into your bloodstream. Too much PTH can become a problem in people with kidney disease.
Healthy kidneys convert a hormone called calcitriol to its active form of vitamin D. Calcitriol lets your body absorb calcium from food you eat. When your kidneys are not working well, they start to make less calcitriol – so even if you eat calcium, your body can’t absorb it. PTH kicks in to make sure you always have enough calcium in your blood. Over time, this can weaken your bones.
A blood test can show if your PTH levels are above normal. If they are, your doctor may prescribe a form of active vitamin D.
I have a family member with polycystic kidney disease (PKD). Should I be tested?
Since 60-70 percent of people with PKD have a family member with PKD, asking your doctor about being tested is a good idea. The first test used for PKD is an ultrasound to look at the kidneys and see if there are cysts. This is a non-invasive test. Learning more about PKD may help you to take better care of your kidney health. The PKD Foundation has free information that can help you. You can learn more at 1-800-PKD-CURE or by visiting their website (http://www.pkdcure.org).
What are the symptoms of chronic kidney disease?
Knowing the symptoms of kidney disease can help people detect it early enough to get treatment. Symptoms can include:
If you believe you have any of these symptoms, talk to your doctor about your concerns. This is especially important if you have a close family member who has kidney disease, or if you have diabetes or high blood pressure, which are the main causes of kidney failure.
How can I find out if I have kidney disease?
Your physician can diagnose kidney disease by conducting lab tests and by assessing your symptoms. High blood levels of creatinine and urea nitrogen (BUN) or high levels of protein in your urine suggest kidney disease. Diabetics should have a yearly urine test for microalbumin, small amounts of protein that don’t show up on standard urine protein test.
