What Should You Pay Attention to After Having a Gastric Balloon Inserted?

Low-calorie yet nutritious meals should be preferred. A protein-rich diet can promote weight loss and prevent muscle loss. Chewing food thoroughly facilitates digestion and prevents stomach strain.

It's important to drink enough water in the first few days. Avoid consuming liquids with meals, as they can further distend the stomach. Liquids should be consumed at least 30 minutes before or after meals.

Exercise plays a crucial role in accelerating weight loss. Strenuous exercise should be avoided for the first few weeks after balloon placement. Light walking is acceptable with your doctor's approval. After 2-4 weeks, a healthy, regular exercise program is recommended.

A liquid diet may be recommended for 1-2 days to allow the stomach to heal. Transitioning to solid foods should be done according to the doctor's recommendations. After balloon removal, it's important to remain under medical supervision for a period of time and maintain a healthy diet.

• Severe Abdominal Pain : The displacement of the gastric balloon can cause pain by pressing on the stomach wall. This pain is often more pronounced in the morning.
• Bloating : If the balloon shifts, it may cause discomfort by over-inflating the stomach.
• Nausea and Vomiting : When the stomach contents do not empty properly, digestive problems such as nausea and vomiting may occur.
• Difficulty Swallowing : Displacement of the gastric balloon may create problems with the esophagus and lead to difficulty swallowing.
• High fever or signs of infection : If the balloon ruptures and injures the stomach, the risk of infection may increase. This may include high fever, chills, or general weakness.
• Rapid Breathing or Difficulty Breathing : Injury to the stomach can trigger difficult breathing as it can also put pressure on the respiratory system.
• Rapid Weight Loss or Weight Gain : The rupture of the gastric balloon can hinder the body's normal weight loss process or, conversely, lead to weight gain due to water retention in the body.
