While the gastric balloon procedure is considered to be a safer and less invasive alternative to other weight loss surgeries, it’s not without risks. Here are some potential complications and side effects that may occur:

  1. Nausea and Vomiting: Many patients experience nausea and vomiting after balloon placement, especially in the first few days as the body adjusts to the balloon.
  2. Abdominal pain: Patients may feel discomfort or pain in the abdomen due to the presence of the balloon.
  3. Gastric Perforation or Ulcer: Though rare, there’s a risk of injury to the stomach, including perforation (a hole) or the development of an ulcer.
  4. Balloon Deflation: There’s a chance that the balloon could deflate on its own. If this happens, there’s a risk it could move through the digestive system and cause a blockage that may require further treatment.
  5. Dehydration: Due to vomiting or not being able to consume enough fluids, some patients might suffer from dehydration.
  6. Weight regain: The gastric balloon is only a temporary tool for weight loss. If you don’t make permanent changes to your diet and exercise habits, you could regain the weight once the balloon is removed.
  7. Esophageal Injury: This is a rare but serious complication where the esophagus can be injured during the insertion or removal of the balloon.

Remember, it’s crucial to discuss the potential risks and benefits with your healthcare provider before deciding on any kind of weight loss procedure.
