10 Signs You May Have Kidney Disease

While the only way to know for sure if you have kidney disease is to get tested, there are a number of physical signs. Sometimes people attribute these physical symptoms of kidney disease to other conditions. This is because those with kidney disease tend not to experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine.

More than 26 million American adults are living with kidney disease. Most don't know it -- Over 90 percent of people with signs of kidney disease are unaware of it. March is National Kidney Month, and one of the best ways to observe this health awareness month is by getting tested if you're at risk for kidney disease. Major risk factors include high blood pressure, diabetes, a family history of kidney failure and being age 60 or older.

While the only way to know for sure if you have kidney disease is to get tested, there are a number of physical signs. Sometimes people attribute these physical symptoms of kidney disease to other conditions. This is because those with kidney disease tend not to experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine.

Here are 10 possible signs you may have kidney disease:

  1. You're more tired, have less energy or are having trouble concentrating. A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. This can cause you to feel tired, weak and can make it hard to concentrate. Another complication of kidney disease is anemia, which can also cause weakness and fatigue.

  • You're having trouble sleeping. When the kidneys aren't filtering properly, toxins stay in the blood rather than leaving the body through the urine. This can make it difficult to sleep. There is also a link between obesity and chronic kidney disease, and sleep apnea is more common in those with chronic kidney disease.

  • You have dry and itchy skin. Healthy kidneys do many important jobs. They remove wastes and extra fluid from your body, help make red blood cells, keep bones strong and work to maintain the right amount of minerals in your blood. Dry and itchy skin can be a sign of the mineral and bone disease that often accompanies advanced kidney disease, when the kidneys are no longer able to keep the right balance of minerals and nutrients in the blood.

  • You feel the need to urinate more often. If you feel the need to urinate more often, especially at night, this can be a sign of kidney disease. When the kidneys' filters are damaged, it can cause an increase in the urge to urinate. Frequent urination can also be a sign of a urinary infection or enlarged prostate in men.

  • You see blood in your urine. Healthy kidneys typically keep blood cells in the body when filtering wastes from the blood to create urine. However, when the kidneys have been damaged, these blood cells can start to "leak" out into the urine. In addition to signaling kidney disease, blood in the urine can be indicative of tumors, kidney stones or an infection.

  • Your urine is foamy. Excessive bubbles in the urine -- especially ones that require you to flush several times before they go away -- indicate protein in the urine. This foam may look like the foam you see when scrambling eggs, as the common protein found in urine, albumin, is the same protein as in eggs.

  • You're experiencing persistent puffiness around your eyes. Protein in the urine is an early sign that the kidneys' filters have been damaged, allowing protein to leak into the urine. This puffiness around your eyes can be due to the fact that your kidneys are leaking a large amount of protein in the urine, rather than keeping it in the body.

  • Your ankles and feet are swollen. Decreased kidney function can lead to sodium retention, causing swelling in your feet and ankles. Swelling in the lower extremities can also be a sign of heart disease, liver disease and chronic leg vein problems.

  • You have a poor appetite. This is a very general symptom, but a buildup of toxins resulting from reduced kidney function can be one of the causes.

  • Your muscles are cramping. Electrolyte imbalances and cramping can be caused by impaired kidney function. For example, low calcium levels and poorly controlled phosphorus may contribute to muscle cramping.

    • Be sure to mention any symptoms you're experiencing to your healthcare practitioner. Request simple urine (ACR) and blood (eGFR) tests for kidney disease if you're at risk.
