Palliative care encompasses a holistic approach aimed at improving the quality of life for patients with incurable diseases, focusing on symptom control and alleviating psychosocial, spiritual, and physical distress. One of the primary challenges in palliative care is ensuring adequate nutrition and hydration for patients whose disease symptoms limit their ability to ingest food and liquids. Symptoms such as dysphagia, cachexia, loss of appetite, nausea, vomiting, constipation, and diarrhea often complicate nutritional support, further compromising patients' health. Oral feeding, as the natural method of nutrient intake, is always the first choice, but it is often not feasible due to physiological issues caused by disease progression. In cases where oral intake is not possible or insufficient, enteral feeding via tube or parenteral feeding via intravenous administration is used. Enteral feeding allows patients to be nourished while maintaining the function of the digestive system, whereas parenteral nutrition is reserved for patients whose digestive system is not functioning. Nurses play a key role in the early detection of cachexia, assessing nutritional status, implementing nutritional interventions, and providing psychosocial support to patients and their families. They also have a crucial role in decision-making and addressing ethical issues related to this field.
