Some symptoms that can indicate a kidney problem or disease are nausea, edema of the feet and ankles, itchy skin, loss of appetite, feeling weak or tired, nausea, weigh loss, headaches, trouble sleeping, urination changes, hypertension and breathing problems, states Mayo Clinic. However, these symptoms tend to manifest in time and suggest some type of kidney damage. Chronic kidney disease can lead to kidney failure, which occurs when the kidneys stop working, relates the American Kidney Fund.
People with kidney failure need either dialysis or a kidney transplant. Kidney failure is a later stage of chronic kidney disease.
However, kidney disease can progress very slowly. These symptoms can be evident after 3 months after kidneys begin to fail in some people, states WebMD. In other people, it can take many years before these symptoms are present.
To detect kidney disease, doctors can use urine and blood tests. One test that is often used to see how well the kidneys are functioning are a urea Bun test. This test can measure the amounts of creatinine and nitrogen level in the blood. In the later stages of kidney disease, the amount of these two substances tend to increase, according to WebMD. Some other tests used to diagnose the disease are a CT scan and ultrasound.
