An intragastric balloon can make you feel fuller faster than you normally would, which often means you’ll eat less. One reason why may be that the intragastric balloon slows down the time it takes to empty the stomach. Another reason may be that the balloon seems to change levels of hormones that control appetite.
The amount of weight you lose also depends on how much you can change your lifestyle habits.
Loss of about 10 to 15 percent of body weight is typical during the six months following intragastric balloon placement. In a randomized clinical trial with 255 adults with a BMI between 30 and 40, people who had the intragastric balloon procedure along with behavioral therapy lost 29 percent of their excess weight, compared to 14 percent in a group that received behavioral therapy alone.
As with other procedures and surgeries that lead to significant weight loss, the intragastric balloon may help improve or resolve conditions often related to being overweight, including:
- Heart disease or stroke
- High blood pressure
- Severe sleep apnea
- Type 2 diabetes
