Once the gastric balloon has settled it should not feel uncomfortable. However there can be a degree of discomfort after it has been placed in the stomach.
Most gastric balloon patients experience reflux because there is less room within the stomach. To avoid this, it is important that your meals are small and you take daily medication to suppress the stomach acid.
In the first 48 hours after having a gastric balloon installed, it is common to experience griping abdominal pains or cramps. This is because the balloon can irritate the muscle of the stomach wall. This usually settles over the course of a few days.
Nausea and vomiting is also a common after effect of having a gastric balloon fitted. This can affect up to 95 percent of people who have just had a gastric balloon installed. These gastric symptoms may last for two to three days after the procedure.
