IgA nephropathy is characterized by the deposition of IgA in the glomerular mesangial regions and is a common type of glomerulonephritis. It is also a major cause of uremia. IgA nephropathy typically affects adolescents. Once diagnosed, patients primarily experience recurrent macroscopic hematuria, especially after skin infections or respiratory infections, during which blood in the urine becomes more apparent. Of course, there can also be asymptomatic hematuria and increased urinary protein. Some patients with IgA nephropathy may also experience edema, particularly in the eyelids and facial area upon waking up in the morning, and in severe cases, there may be an increase in blood pressure and a decline in kidney function. It is essential for patients with IgA nephropathy to have regular follow-ups to monitor changes in routine urine tests, kidney function, and blood pressure, and to seek active treatment if the condition worsens.
