Hi!There are no specific restrictions regarding sexual activity after balloon placement. You can feel free to do as you like once you feel well. Most people probably wouldn't feel up to it for the first few days after balloon placement, in general. Hope that helps!
It varies per patient, I recommend waiting for at least a week and make sure you do not have any symptoms after the balloon (like nausea, vomiting, abdominal discomfort). If any problems occur after resuming sexual activity then abstain and seek medical evaluation
