Free water restriction often is appropriate for patients with normovolemic hypotonic hyponatremia.

Individuals who are undernourished need to maintain an appropriate solute intake. In fact, in patients with SIADH, a high protein intake increases the solute load for excretion, thereby removing more free water. Although unpalatable, oral urea has been used to achieve the same effect.

Patients with hyperglycemia or hyperlipidemia should receive appropriate nutritional counseling.
