This is a new device. It uses pump to drain part of the food in your stomach about half an hour after a meal, according to NIH. A tube goes from the inside of your stomach to a port on the outside of your abdomen. Your body doesn’t absorb about 30 percent of calories you ate. You can have the device removed at any time. The AspireAssist is intended for a long-term duration of use, the FDA says. However, previous abdominal surgery significantly increases the medical risks of gastrostomy tube placement; inflammatory bowel disease can be a complication; and people who have a history uncontrolled hypertension should not use it.
