A method is provided in which continuous suction alternately removes fluid through an aspiration lumen from the stomach and adjacent small intestine and returns the fluid with gravity a short distance downstream. The only aspirate permanently discarded is that volume of inflow to the feeding site that momentarily exceeded peristaltic outflow. Feeding is also continuous, which allows for a smaller and more comfortable feeding tube. This frequent aspiration and feeding serves to provide the maximum safe nutrition, while preventing overfeeding and its associated risks of intestinal distention.
