Yes. For recovery purposes after the operation, gastric band patients, gastric balloon patients, and general bariatric surgery patients will be required to follow a strict diet based on smashed food and light liquids (no alcohol or soft drinks). Also, smoking should be absolutely avoided as long as possible after a gastric band surgery or gastric sleeve surgery. Your surgeon will provide you with all the necessary instructions concerning your dietary requirements right after surgery, for the next 8 weeks, including medication and vitamin supplements.
