10 Signs of Kidney Disease You Should Know

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. However, when the kidneys do fail it leads to death. Here are the top signs and symptoms of kidney disease to look for.
Changes in Urination
• Waking up at night to urinate
• Urinating more frequently than usual
• Urine that is foamy or bubbly
• Urinating less often, or in smaller amounts than usual with dark colored urine
• Blood in the urine
• A feeling or pressure while urinating
• Difficulty urinating


Failing kidneys don’t remove extra fluid. As a result, the fluid builds up in the body causing swelling in the legs, ankles, feet, face or hands.


When the kidneys are healthy, they make a hormone called erythropoietin that tells the body to make oxygen-carrying red blood cells. As the kidneys fail, they make less erythropoietin. With fewer red blood cells to carry oxygen, the muscles and brain become tired very quickly. This condition is known as anemia.

Feeling Cold

Anemia can make a person feel cold all the time, even in a warm room.

Dizziness and Trouble Concentrating

Anemia related to kidney failure means that the brain is not getting enough oxygen. This can lead to memory problems, trouble with concentration, and dizziness.

Shortness of Breath

When kidney disease is present, extra fluid in the body can build up in the lungs. In addition, anemia can leave the body oxygen-starved and short of breath.

Leg Pain

Some people with kidney problems may have pain in the back or side related to the affected kidney. Polycystic kidney disease, which causes large, fluid-filled cysts on the kidneys and sometimes the liver, can cause pain.


When the kidneys fail, the buildup of wastes in the blood can cause severe itching and skin rashes.

Metallic Taste in the Mouth

A buildup of wastes in the blood (called uremia) can make food taste different and cause bad breath. A person with kidney problems may also notice that a metallic taste in the mouth. They may suddenly stop liking to eat meat, or they may lose weight because they don’t feel like eating.

Nausea and Vomiting

A severe buildup of wastes in the blood (uremia) can cause nausea and vomiting.
What Causes Kidney Disease?
Diabetes and high blood pressure are the leading causes of kidney disease. These conditions cause about 70 percent of kidney failure cases.
Early kidney disease has no signs or symptoms. The only way to know if your elderly parent has kidney disease is to get checked.
Kidney disease does not go away. It may get worse over time and can lead to kidney failure. If the kidneys fail, the only options are dialysis or a kidney transplant.
Kidney disease can be treated. The sooner you know your parent has it, the sooner you can take steps to keep your kidneys healthy longer.
A person is also at risk for kidney disease if they have heart disease or close relative who has kidney disease.
Testing for Kidney Disease
If you suspect kidney disease, get blood and urine tests to check for kidney disease. A blood test measures GFR, which indicates how well the kidneys are working. GFR stands for glomerular filtration rate.
A urine test measures the amount of protein in the urine. Protein can leak into the urine when the kidneys are not working well. Ask your healthcare provider about blood pressure medicines that can help slow down kidney disease.
