Your kidneys remove excess fluid from your blood. When this doesn’t occur, that fluid builds up in your body. This causes swelling in your:
- ankles
- legs
- feet
- hands
- face
Swelling can also occur in your lungs. This can cause shortness of breath. Another sign is swelling or puffiness around your eyes.
Back pain
You can feel kidney pain in your back or sides, usually in the middle of your back just below your rib cage.
Skin rash or itch
The buildup of waste products in your blood can cause a skin reaction, resulting in rashes or severe itching.
Fatigue
A secondary function of your kidneys is to help make red blood cells that carry oxygen all around your body.
A decrease in red blood cells is called anemia. It causes:
- tiredness
- decreased stamina
- sometimes dizziness or memory concerns
Fatigue brought on by kidney disease can also be caused by a buildup of metabolic waste in your blood.
Loss of appetite
A loss of appetite is common in people with advanced kidney disease. This may lead to undernutrition and weight loss.
People experiencing kidney disease should talk with a healthcare provider about finding foods that are appealing and provide nutrients.
Nausea or vomiting
Vomiting can occur when metabolic waste builds up in your blood, but people may feel nauseated at even the thought of eating.
Muscle cramps
Painful muscle cramps, specifically leg cramps, can also occur with kidney disease.
The bottom line
Kidney disease is a condition that can easily go unnoticed until the symptoms become severe. Including a kidney function test as part of your regular checkup will help you and your doctor to address any potential underlying causes of kidney problems.
