Great question. I always counsel patients on the possibility of early, severe nausea and vomiting, or even dehydration. This isn't common, but could occur. We try to avoid this by pre-medicating with strong anti-nausea medications and as needed medications if symptoms arise (cramping, nausea). Occasionally, we will need to provide IV fluids if you are feeling very dehydrated. This usually helps tremendously and can help you get beyond the early adjustment period. Again, this is not common. Most patients have mild cramping and nausea that subsides quickly. Of course, if you really could not tolerate the balloon despite these measures, it could be removed early. We always strive to prevent this outcome, because we certainly want you to have the absolute best success with the device.
