Uremia primarily refers to high levels of creatinine in the blood. Generally, a creatinine blood test can be used to evaluate kidney function, thus diagnosing whether the kidneys are in a compensatory stage, in a chronic stage, or during a period of uremia. Renal insufficiency, which causes uremia, has specific causes. It is essential to determine whether the causes are renal or post-renal by performing routine urinary system CT scans to identify any obstructions, stones, or space-occupying lesions that may lead to hydronephrosis and a decline in renal function. Other internal medical diseases, such as chronic nephritis syndrome and kidney disease, can also lead to increased creatinine levels. In such cases, renal biopsy and pathology are necessary to confirm the diagnosis. Once an individual reaches the uremic stage, the overall condition tends to deteriorate, characterized by fatigue, anorexia, and weight loss. Additional issues include toxin accumulation in the body leading to anemia and various other problems, including gastrointestinal issues and reduced digestive capacity resulting in loss of appetite. When the aforementioned symptoms occur, there generally are only two treatment options: dialysis to filter out the toxins or, if an appropriate kidney source is available and economically feasible, kidney transplantation can be considered.
