What stage of kidney disease is chronic glomerulonephritis with (+++) proteinuria?

There is no such thing as staging for chronic glomerulonephritis; therefore, it is incorrect to refer to proteinuria (+++) in chronic glomerulonephritis as a specific stage of kidney disease. The detailed explanation is as follows:

Chronic glomerulonephritis is a group of diseases originating in the glomeruli, with a slow onset and a disease course typically lasting more than three months. Common symptoms include edema, hypertension, and proteinuria. Clinically, chronic glomerulonephritis does not have defined stages. However, when explaining the condition to patients, doctors may classify it as mild, moderate, or severe based on the severity of symptoms such as proteinuria and hematuria, as well as the degree of renal function impairment. Proteinuria (+++) indicates a high level of protein detected during qualitative urine testing. However, diagnosis cannot be made based solely on proteinuria; it must be evaluated in conjunction with other patient examinations.

Patients with chronic glomerulonephritis should actively seek medical treatment. If hypertension is present, medications such as irbesartan tablets or captopril tablets may be used. Additionally, diuretics such as hydrochlorothiazide tablets or furosemide tablets should be taken as prescribed. During treatment, intake of dietary protein and phosphorus should be restricted, and adequate rest is essential.
