What is the common dietary restriction for patients with AGN?

Patients with acute glomerulonephritis (AGN) often experience fluid retention and hypertension due to impaired kidney function. A moderate sodium restriction is recommended to help manage these issues. Reducing sodium intake can help decrease blood pressure and prevent edema, which are common complications associated with AGN. The goal of dietary modifications in these patients is to alleviate stress on the kidneys while providing adequate nutrition.

In contrast, a high protein intake could exacerbate the workload on the kidneys, leading to further deterioration of kidney function. Calorie restriction is generally not appropriate, as patients need enough calories to maintain their energy levels and support recovery. A high potassium intake is also not advisable, as kidney dysfunction can impair potassium excretion, leading to hyperkalemia, which can have serious cardiovascular effects. Thus, moderate sodium restriction stands out as the most fitting dietary recommendation for patients with AGN.
