Key Takeaways

Clinical nutrition represents an indispensable therapeutic modality for patients in whom conventional oral intake is physiologically unfeasible, deficient, or contraindicated. Advances in artificial access devices, ambulatory infusion pump technology, and standardized sterile formulations have facilitated the safe transition of medical nutrition from acute inpatient wards into the patient's domestic setting—realized as Home Enteral Nutrition (HEN) and Home Parenteral Nutrition (HPN). This paradigm substantially curtails healthcare costs and nosocomial infection risks while profoundly elevating functional autonomy, emotional well-being, and social reintegration. This review delineates clinical eligibility criteria, enteral and vascular access methodologies, formulation selection, and complication mitigation in home nutrition therapy.

Nutritional treatment at the hospital

However, the underlying causes of malnutrition that are known are elderly patients with respiratory diseases, inflammatory bowel diseases and malignant cancers. When well-nourished patients are hospitalized, there is often a lack of nutrition, which can be caused by the course of a serious illness, surgery or infection. The underlying cause of mal nutritional deficiency is: the disease and its effects, the lack of appetite, the inadequate intake of blood, the digestive tract, and the intake to the digestion of nutrients, the increased demand for nutrients may be due to a long-term diet.

Food therapy at home

When the patient is in good health and further hospitalization is not required, food therapy (both inpatient and non-patient) can be carried out safely at home. The patient who is receiving the intravenous treatment receives specially prepared mixtures containing proteins, carbs, carbohydrates, electrolytes, vitamins, trace elements and water provided by the food processor.
