Precautions for hyponatremia in the elderly

Patients should avoid raw and cold foods. In the early stages, patients with hyponatremia must strictly control their water intake and should be given a high-sodium or regular diet. Patients with heart disease or hypertension should not consume excessive salt. They should eat more salty foods to replenish the body's sodium deficiency and maintain balance. Patients may consume foods such as leafy vegetables, whole grains, and nuts.
