Answer

A low-sodium, low-protein diet should be prescribed during the acute phase, when edema and hypertension are in evidence; however, prolonged dietary restrictions are not warranted. Limitation of fluid and salt intake is recommended in the child who has either oliguria or edema. Curtailment of fluid to amounts consistent with insensible losses helps to minimize vascular overload and hypertension. In patients with oliguric acute kidney injury, potassium intake should be restricted to prevent hyperkalemia.

Limited activity is probably indicated during the early phase of the disease, particularly if hypertension is present. Bedrest may lessen the degree and duration of gross hematuria if present; however, longer periods of bedrest do not appear to influence the course or long-term prognosis; therefore, they are generally not recommended.
