Weight Loss Balloons
What is a gastric balloon?
Gastric balloon, also called endoscopic intragastric balloon, is a non-surgical weight-loss procedure which involves the insertion of a specialized balloon inside the stomach to occupy space and limit the food carrying capacity of the stomach. This makes you feel full sooner and limits your intake to smaller portions. The procedure is temporary, and the balloon is usually removed after a period of 6 months.
What is Obesity?
Obesity is an excess of total body fat which results from caloric intake that exceeds energy usage. A measurement used to assess health risks of obesity is Body Mass Index or BMI.
Indications and Contraindications
The gastric balloon is indicated in the following patients:
- BMI 30-40 kg/m2
- Unable to lose weight with exercise and diet
- Willing to participate in a medically-supervised lifestyle and behavior modification program
The weight loss system is contraindicated in the following patients:
- Have previously undergone bariatric surgery
- Are suffering from inflammatory diseases of the GI tract, large hiatal hernia, structural abnormalities in the pharynx or esophagus, and are prone to upper GI bleeding
- Allergy to materials used during the procedure
- Alcoholics or drug abusers
- Women who are pregnant or breastfeeding
The placement of the gastric balloon is carried out as an outpatient procedure.
The procedure is performed endoscopically under sedation. The deflated gastric balloon is attached to an endoscope, a narrow lighted tube with a camera attached, which is guided through your mouth and into the stomach. Once in proper position, your doctor inflates the balloon with saline and a dye, or gas to the desirable size. While the endoscope is removed, the balloon is retained in the stomach. The entire procedure takes about 15 minutes to complete. You will be able to leave the hospital soon after.
The balloon is temporarily left in the stomach for about 6 months, following which it is removed. The removal of the gastric balloon is also performed under sedation.
Following the procedure, your throat might feel a little sore and you may experience some cramps and nausea as your stomach adjusts to the balloon.
You will be on a liquid or soft diet for a few weeks. This is followed by 6 months of supervised diet and behavior-modification that will be taken care of by a multidisciplinary team of nutritionists, gastroenterologists and medical weight loss physicians. This helps you to continue eating healthy and staying active, which will greatly influence results.
Risks and Complications
The Gastric balloon procedure is generally safe but as with any procedure complications may occur and can include:
- Esophageal or gastric ulcers or perforation
- Deflation of the balloon which can lead to blockage.
Should the balloon rupture, the dye if used, will be released in the urine and you can notify your doctor immediately.
