Matters needing attention in life of patients with IGA nephropathy include avoiding fatigue, removing infection and other incentives, avoiding contact with nephrotoxic drugs or poisons, adopting a healthy lifestyle such as quitting smoking, exercising moderately and controlling emotions, and eating reasonably. In the acute stage, you should stay in bed, and then gradually increase the activity after the clinical symptoms improve. In acute stage, a low-salt diet below 3g should be given every day. People with normal renal function don't need to limit the intake of protein, but azotemia needs to limit the intake of protein, mainly with high-quality animal protein. Oliguria should limit the amount of liquid.
