Eating disorders affect nutritional status and psycho-mental development of the child. When the child is ill, such disorders may be exacerbated, leading to malnutrition and thus affecting the course of underlying disease and its duration, the number and type of complications, as well as the prognosis. The risk of malnutrition is most commonly observed in chronically ill children or in patients with dysphagia secondary to CNS damage. Symptoms of dysphagia and/or malnutrition indicate the need for developing an individual nutritional protocol, and in malnourished patients--for initiating aggressive nutritional treatment. The report analyzes the decision-making algorithm employed in nutritional interventions, types of diets and routes of their administration.
