A system and method for determining an adjustment to a gastric band, and more specifically to determining an adjustment to a gastric band based on satiety state data and weight loss data. The gastric band information system can determine an adjustment of the gastric band using a gastric band adjustment algorithm. The gastric band information system can wirelessly transmit the adjustment to the gastric band. The gastric band information system can receive gastric band data, weight data, glucose data, and/or blood pressure data and display a gastric band chart, a weight chart, and/or a blood pressure chart. The gastric band information system can also receive gastric band implantation data, patient data, and/or any other medical data. The various data can be received from a computer or medical devices in a wired or wireless manner.
