If you have any medical risks due to problems with your bowels/intestines (such as bowel obstruction), any esophageal injuries, and other related issues, you may want to think about a different weight loss procedure. The procedure often produces cramping, nausea, vomiting, gastro-oesophageal reflux and discomfort immediately following placement. There is a slight risk of balloon deflation while inside the stomach, which can cause obstruction.
There is always a chance for any weight loss surgery to face weight gain or failure. The problem with gastric balloon is after it is removed, there is nothing besides willpower and determination in the way of regaining weight and going back to bad habits.
This is why it is so critical to be 110% committed to making serious lifestyle changes. These include dietary changes, exercise, eating habits, post-op diet, and changing your overall life. Conversion of failed stomach balloon can be done through stomach stapling.
