Question 1

What procedures fall under minimal access GI and bariatric surgery?

Accepted Answer

This speciality covers laparoscopic (keyhole) surgery for digestive system conditions, including gallbladder removal, hernia repair, and bowel surgery, as well as bariatric (weight loss) procedures such as gastric sleeve, gastric bypass, and other surgical options for severe obesity. These procedures use small incisions and a camera to perform surgery with less tissue trauma than traditional open surgery, typically resulting in faster recovery for suitable patients.

Question 2

Who is a candidate for bariatric (weight loss) surgery?

Accepted Answer

Bariatric surgery is generally considered for individuals with a body mass index (BMI) of 40 or above, or a BMI of 35 or above with obesity-related health conditions like type 2 diabetes, high blood pressure or sleep apnoea, who haven't achieved lasting weight loss through diet and lifestyle changes alone. Candidates undergo a thorough medical, nutritional and psychological evaluation before surgery to ensure they're prepared for the significant lifestyle changes required afterward. Your surgical team will assess whether you meet the criteria and which procedure best suits your health profile.

Question 3

What is the difference between gastric sleeve and gastric bypass surgery?

Accepted Answer

Gastric sleeve surgery removes a large portion of the stomach, creating a smaller, tube-shaped stomach that limits food intake and reduces hunger-related hormones. Gastric bypass creates a small stomach pouch and reroutes part of the small intestine, both restricting food intake and reducing calorie absorption. Bypass surgery generally produces slightly greater weight loss and can be more effective for certain conditions like severe acid reflux or type 2 diabetes, but it involves a more complex operation with more re-routing of the digestive tract. Your bariatric surgeon will recommend the option best suited to your specific health profile and goals.

Question 4

What lifestyle changes are needed after bariatric surgery?

Accepted Answer

After bariatric surgery, patients need to follow a structured, staged diet progression, starting with liquids and gradually advancing to solid foods over several weeks, along with lifelong vitamin and mineral supplementation, since the surgery affects nutrient absorption. Eating small, frequent, protein-focused meals, chewing thoroughly, and avoiding high-sugar or high-fat foods are important long-term habits. Regular follow-up with the bariatric team, along with sustained physical activity, supports both successful weight loss and long-term weight maintenance.

Question 5

What are the risks and possible complications of bariatric surgery?

Accepted Answer

As with any major surgery, risks include bleeding, infection, and blood clots, along with procedure-specific risks such as staple line leaks, or nutritional deficiencies if supplementation isn't followed consistently after surgery. Longer-term risks can include gallstones from rapid weight loss, or, less commonly, dumping syndrome after gastric bypass, causing nausea and discomfort after eating certain foods. Choosing an experienced bariatric surgical team and closely following pre- and post-surgical guidance significantly reduces the likelihood of serious complications.
