Qualification for Operation

If your BMI is above 40, or between 35-40 and you also have other health issues, you are allowed to do both Roux-en-Y gastric bypass and sleeve gastrectomy. Although both operations help control diabetes, hypertension, or sleep apnea, you should be aware that gastric bypass surgery is more effective than gastric sleeve surgery in doing so.

Method of Surgery

Gastric bypass surgery entails reducing the size of the stomach and omitting a portion of the small intestine. This method is a little more invasive than sleeve gastrectomy. This method is more invasive than sleeve gastrectomy and has a higher risk of complications, such as dumping syndrome. However, it also results in the most effective weight loss in the short and long term. Dumping syndrome is more frequent after gastric bypass surgery.

On the other hand, sleeve gastrectomy eliminates around 80% of the stomach, including the appetite hormone, but does not affect the body’s ability to absorb nutrients. Its recovery time is shorter compared to gastric bypass.
Both procedures are suitable for people with a BMI above 40 or between 35-40 with other health issues. Gastric bypass may be more effective for managing diabetes, hypertension, or sleep apnea.

If you’ve decided to have weight loss surgery, you should consider how much weight you will lose in the long run, which depends on your lifestyle rather than the surgical technique.

In Gastric bypass, you may lose 60 per cent to 80 per cent of your weight in the first 12 to 18 months.
