Question
How severe is IgA nephropathy stage 3, and what serious issues might arise subsequently?
Answer
IgA nephropathy stage 3 refers to primary glomerulonephritis characterized by predominant IgA or IgA deposits in the glomerular mesangial area, accompanied or not by deposits of other immunoglobulins. Clinical manifestations include recurrent gross hematuria or microscopic hematuria, which may be accompanied by varying degrees of proteinuria, and some patients may experience severe hypertension or renal insufficiency. It is recommended to further check kidney function and urine routine to assess the severity of the condition. If kidney function and indicators of hematuria and proteinuria are normal, the condition is relatively mild.
