Chronic kidney disease, also called chronic kidney failure, involves a gradual loss of kidney function. Your kidneys filter wastes and excess fluids from your blood, which are then removed in your urine. Advanced chronic kidney disease can cause dangerous levels of fluid, electrolytes and wastes to build up in your body.
In the early stages of chronic kidney disease, you might have few signs or symptoms. You might not realize that you have kidney disease until the condition is advanced.
Treatment for chronic kidney disease focuses on slowing the progression of kidney damage, usually by controlling the cause. But, even controlling the cause might not keep kidney damage from progressing. Chronic kidney disease can progress to end-stage kidney failure, which is fatal without artificial filtering (dialysis) or a kidney transplant.
1. Fatigue – being tired all of the time
Healthy kidneys make a hormone called erythropoietin, or EPO, that tells your body to make oxygen-carrying red blood cells. As the kidneys fail, they make less EPO. With fewer red blood cells to carry oxygen, your muscles and brain tire very quickly. This is anemia, and it can be treated.
2. Shortness of breath – after very little effort
Being short of breath can be related to the kidneys in two ways. First, extra fluid in the body can build up in the lungs. And second, anemia (a shortage of oxygen-carrying red blood cells) can leave your body oxygen-starved and short of breath.
3. Feeling faint, dizzy, or weak
Anemia related to kidney failure means that your brain is not getting enough oxygen. This can lead to feeling faint, dizzy, or weak.
4. Trouble thinking clearly
Anemia related to kidney failure means that your brain is not getting enough oxygen. This can lead to memory problems or trouble with concentration.
5. Feeling very itchy
Kidneys remove wastes from the bloodstream. When the kidneys fail, the build-up of wastes in your blood can cause severe itching.
6. Swelling in hands or feet
Failing kidneys don’t remove extra fluid, which builds up in your body causing swelling in the legs, ankles, feet, and/or hands.
7. Swollen or puffy face
Failing kidneys don’t remove extra fluid, which builds up in your body causing swelling in the face.
8. Food tastes like metal
A build-up of wastes in the blood (called uremia) can make food taste different and cause bad breath. You may also notice that you stop liking to eat meat, or that you are losing weight because you just don’t feel like eating.
9. Ammonia breath
A build-up of wastes in the blood (called uremia) can cause bad breath.
10. Upset stomach, nausea, vomiting
A severe build-up of wastes in the blood (uremia) can also cause nausea and vomiting. Loss of appetite can lead to weight loss.
