Hyperoxaluria and oxalosis are medical conditions that occur when there is an excess amount of oxalate in the urine or blood. This can happen due to several reasons, including a genetic disorder or a diet that is rich in oxalate. There are several synonyms for these conditions, including oxalate nephropathy, oxalate uropathy, and calcium oxalate deposition disease. These conditions can lead to several health complications such as kidney stones, chronic kidney disease, and even kidney failure if left untreated. Therefore, it is important to seek medical attention if you experience any symptoms such as pain while urinating, blood in urine, or lower back pain.
