Chronic kidney disease stage III generally refers to chronic kidney disease stage III, also known as CKD stage 3, which is determined based on glomerular filtration rate calculation. Chronic kidney disease stage III, where the glomerular filtration rate is between 30-60 ml/min, is a functional diagnosis, or functional stage, and is not able to determine what kind of disease it is caused by. Patients with stage III chronic kidney disease are generally able to compensate for their kidney function, and patients will not have serious complications such as edema and hyperkalemia. However, there may be renal hypertension, renal anemia, etc., and even serious complications such as renal bone disease may occur. Chronic kidney disease is divided into five stages, and if it reaches stage V, it is equivalent to previous uremia and needs dialysis treatment. In addition, stage III kidney disease may also refer to the stages of various pathological types, such as IgA nephropathy stage III, membranous nephropathy stage III, lupus nephritis stage III, etc.
