What’s the difference between a gastric sleeve and a gastric bypass?
Gastric sleeve and gastric bypass are two of the most common bariatric surgeries for weight loss. Both procedures aim to help individuals with obesity achieve significant and sustained weight loss by reducing the size of the stomach and limiting the amount of food that can be consumed. However, the two procedures differ in the way they accomplish these goals.
Gastric Sleeve Surgery: This is a restrictive type of bariatric surgery that involves removing a large portion of the stomach, leaving a narrow, banana-shaped sleeve that restricts the amount of food that can be consumed. The surgery helps to reduce hunger and promote feelings of fullness, leading to decreased food intake and weight loss. Gastric sleeve surgery is performed using minimally invasive laparoscopic techniques and typically takes one to two hours to complete. The procedure is typically performed as a day surgery, with patients being able to return home the same day.
Gastric Bypass Surgery: This is a combination of restrictive and malabsorptive type of bariatric surgery. In this procedure, the surgeon creates a small stomach pouch and then reroutes the small intestine to this new pouch, bypassing the majority of the stomach and the first part of the small intestine. This results in food bypassing a significant portion of the small intestine, where most calories and nutrients are absorbed, leading to decreased calorie and nutrient absorption and promoting weight loss. Gastric bypass surgery is also typically performed using laparoscopic techniques, taking two to four hours to complete.
Both gastric sleeve and gastric bypass procedures have been shown to be effective for weight loss, and the choice of which procedure to have depends on several factors, such as the patient’s individual health status, weight history, and personal preferences. It’s important to discuss the options with a qualified bariatric surgeon and make an informed decision based on the recommendations and guidance of a medical professional.
Gastric sleeve surgery is a good option for patients who want a less invasive procedure and are looking for a simple solution to weight loss. Gastric bypass, on the other hand, is a more complex procedure and is typically recommended for patients with a higher body mass index (BMI) or for those with other obesity-related health conditions such as type 2 diabetes or sleep apnoea.
Both procedures come with potential risks and side effects, such as infection, blood clots, or bleeding. Patients who undergo bariatric surgery should also be prepared for lifestyle changes, including a commitment to a healthy diet and regular exercise, in order to achieve long-term weight loss success.
In conclusion, gastric sleeve and gastric bypass are two effective weight loss options for individuals with obesity. The decision of which procedure to have should be made with the guidance of a qualified bariatric surgeon and should take into consideration individual health status, weight history, and personal preferences. Patients who undergo bariatric surgery should also be prepared for lifestyle changes in order to achieve long-term weight loss success.
