With the rising rates of obesity and related health problems, more people are seeking effective, safe solutions for weight loss. One of the most popular and simple non-invasive options is the gastric balloon, which is widely used in many weight loss clinics as an alternative to surgery.
A gastric balloon for weight loss is a soft, expandable medical device inserted into the stomach via endoscopy. It is then filled with saline or gas to occupy space in the stomach, which helps reduce appetite, increase the feeling of fullness, and limit food intake, leading to gradual and safe weight loss.
The procedure takes only 15–20 minutes
The balloon is inserted through the mouth using a gastroscope (endoscopy)
It is filled with sterile saline or gas
No surgery or general anesthesia is required, and the patient can leave the clinic the same How Long Does It Stay in the Stomach?
The duration depends on the balloon type, but it usually stays for 6 to 12 months
After that, the balloon is removed using the same endoscopic technique

Type 2 diabetes
