You are perfectly safe to fly after a gastric balloon procedure. I would recommend waiting a couple weeks so that you have recovered fully, but there is no danger. It will not cause any issues at security or with pressurization during flying.
Hello, thank you for expressing your concern.Congratulations on taking the decision to become healthier.Yes, you can flight overseas safely, here in Dominican Republic we receive a lot of international patients to have the gastric balloon inserted and haven't had any issues returning to their home country with the balloon inserted. Have a consultation with a bariatric surgeon so you can feel more at ease with this manner, contact international doctor to know what are the steps to undergo with the insertion of the balloon overseas.My Best Wishes,
