Items Tagged With kidney failure

Chronic kidney disease is caused by damage to the kidneys. By far the most common causes of this damage are:

• High blood pressure.
• High blood sugar (diabetes).

Other things that can lead to chronic kidney disease include:

• Kidney diseases and infections, such as polycystic kidney disease, pyelonephritis, and glomerulonephritis, or a kidney problem you were born with.
• A narrowed or blocked renal artery. The renal artery carries blood to the kidneys.
• An enlarged prostate gland, kidney stones, or a tumor that keeps urine from flowing out of the kidneys.
• Lead poisoning.
• Long-term use of medicines that can damage the kidneys. Examples include pain medicines, like acetaminophen (such as Tylenol) and ibuprofen (such as Advil), and certain antibiotics.

What are the symptoms?

You may start to have symptoms only a few months after your kidneys begin to fail. But most people do not have symptoms early on. In fact, many do not have symptoms for as long as 30 years or more. This is called the "silent" phase of the disease.

How well your kidneys work is called kidney function. As your kidney function gets worse, you may:

• Urinate less than normal.
• Have swelling from fluid buildup in your tissues. This is called edema (say "ih-DEE-muh").
• Feel very tired or sleepy.
• Not feel hungry, or you may lose weight without trying.
• Often feel sick to your stomach (nauseated) or vomit.
• Have trouble sleeping.
• Have headaches or trouble thinking clearly.

How is chronic kidney disease diagnosed?

Your doctor will do blood and urine tests to help find out how well your kidneys are working. These tests can show signs of kidney disease and anemia. (You can get anemia from having damaged kidneys.) You may have other tests to help rule out other problems that could cause your symptoms.

Your doctor will ask questions about any past kidney problems, whether you have a family history of kidney disease, and what medicines you take-both prescription and over-the-counter drugs.

You may have a test that lets your doctor look at a picture of your kidneys, such as an ultrasound or CT scan. These tests can help your doctor measure the size of your kidneys, estimate blood flow to the kidneys, and see if urine flow is blocked. In some cases, your doctor may take a tiny sample of kidney tissue (biopsy) to help find out what caused your kidney disease.

How is it treated?

Chronic kidney disease is usually caused by another condition. So the first step is to treat the disease that is causing kidney damage.

Diabetes and high blood pressure cause most cases of chronic kidney disease. If you keep your blood pressure and blood sugar near normal, you may be able to slow or stop the damage to your kidneys. Losing weight and getting more exercise can help. You may also need to take medicines.

Kidney disease is a complex problem. You will probably need to take a number of medicines and have many tests. To stay as healthy as possible, work closely with your doctor. Go to all your appointments, and take your medicines just the way your doctor says to.

Lifestyle changes are an important part of your treatment. Taking these steps can help slow down kidney disease and reduce your symptoms. They may also help with high blood pressure, diabetes, and other problems that make kidney disease worse.

• Follow a diet that is easy on your kidneys. A dietitian can help you make an eating plan with the right amounts of salt (sodium) and protein. You may also need to watch how much fluid you drink each day.
• Get some exercise every day. Work with your doctor to design an exercise program that is right for you.
• Do not smoke or use tobacco.
• Do not drink alcohol.

Always talk to your doctor before you take any new medicine, including over-the-counter remedies, prescription drugs, vitamins, or herbs. Some of these can hurt your kidneys.

What happens if my kidney disease gets worse?

When kidney function falls below a certain point, it is called kidney failure. Kidney failure affects your whole body. It can cause serious heart, bone, and brain problems and make you feel very ill.

Once you have kidney failure, you will probably have two choices: start dialysis or get a new kidney (transplant). Both of these treatments have risks and benefits. Talk with your doctor to decide which would be best for you.

• Dialysis is a process that filters your blood when your kidneys no longer can. It is not a cure, but it can help you feel better and live longer.
• Kidney transplant may be the best choice if you are otherwise healthy. With a new kidney, you will feel much better and will be able to live a more normal life. But you may have to wait for a kidney that is a good match for your blood and tissue type. And you will have to take medicine for the rest of your life to keep your body from rejecting the new kidney.

Making treatment decisions when you are very ill is hard. It is normal to be worried and afraid. Discuss your concerns with your loved ones and your doctor. It may help to visit a dialysis center or transplant center and talk to others who have made these choices.
