Parenteral Nutrition is a medical method of providing essential nutrients directly into the bloodstream, bypassing the digestive system. This approach is often used for patients who cannot eat or absorb food normally due to conditions like Crohn's disease, cancer, or after major surgeries. The nutrients delivered include carbohydrates, proteins, fats, vitamins, and minerals, tailored to meet individual needs. The process typically involves the use of an intravenous (IV) line, which can be temporary or long-term, depending on the patient's condition. Healthcare professionals carefully monitor patients receiving parenteral nutrition to ensure they receive the right balance of nutrients and to prevent complications such as infections or imbalances in electrolytes.
