                                Total parenteral nutrition (TPN) is a method of feeding that bypasses the gastrointestinal tract, and is used when someone cannot receive feedings or fluids by mouth. A TPN dietitian is a specialized nutrition expert who manages this complex and critical intravenous feeding regimen for patients who cannot consume food normally.
