Bariatric Surgeries - Summary of Procedures


* % EWL = % excess body weight loss (if normal BMI taken < 25)

Obesity not only has a significant impact on your health, it is also associated with a number of chronic illnesses, including type 2 diabetes and metabolic syndrome. Currently, there are various laparoscopic bariatric surgeries available for patients suffering from morbid obesity. Together with diet control and altering the absorptive system, weight loss can be achieved with a holistic approach.

1. Laparoscopic Adjustable Gastric Band (LAGB)

Asian diet consists mainly of volume instead of fast foods and sweets in the West. The influence of the “Western” portion sizes is causing more and more obese populations worldwide. For BMI over 30, with an over-eating habit, LAGB may be a possible solution for weight loss by reducing the portion size ingested and improving daily eating habits. This is one of the most widely adopted weight loss surgery as it is minimally invasive. Doctors can adjust the band according to the condition of the patient... (More)

2. Gastric-sleeve.html

Want to have a better control of eating volume without the need to avoid various foods? Laparoscopic sleeve gastrectomy, a restrictive minimally invasive laparoscopic surgery, is the most widely performed weight loss surgery in Asia. By reducing the stomach size, patients will feel a sense of fullness much earlier, and thereby substantially reducing the volume intake. Besides more effective weight loss, this surgery is effective in diabetic treatment with a remission rate of almost 70%. This surgery can significantly suppress the secretion of Ghrelin – a powerful appetite stimulating hormone. Patients recover quickly from surgery and are able to return to their daily activities in a short period of time. In order to achieve your target body weight, patients will have regular follow up with Dr. Wong and his team of allied health specialist (including dietitian and physiotherapist)... (More)

3. Gastric-band-plication.html

This is a restrictive laparoscopic procedure that combines the benefits of both gastric banding and gastric plication. It is suitable for patients who wish to restrict their stomach size without removing part of their stomach (ie. it is completely reversible). By folding in the greater curvature of the stomach, stomach size will be reduced (forming a “banana shape” stomach), and thereby effectively limiting the amount of food that could be taken. This surgery also reaps better results than using a gastric band alone. However, as the top part of the stomach responsible for hormone secretion is not removed; appetite is less reduced. Studies have shown that weight regain is significant following plication ONLY, therefore for better long lasting weight loss, a gastric band is also placed for later adjustment if needed... (More)

4. Gastric-bypass.html

Gastric bypass is by far the most effective weight loss surgery for obese as well as diabetic patients with a success rate of over 80%. Gastric bypass is a combination of restrictive and malabsorptive weight loss surgeries. It reduces stomach volume and appetite while bypassing the duodenum to reduce calorie absorption in order to achieve significant weight loss. However, patients are required to take vitamins regularly and undergo regular checkups to prevent the risk of anemia... (More)

5. Intragastric-balloon.html

For patients who are overweight but are still indecisive about undergoing surgery, endoscopic intra-gastric balloon is an option. A saline-filled balloon will be placed inside the top of the stomach, reducing stomach volume and giving a sensation of satiety. This is only a TEMPORARY treatment, as the balloon cannot be placed in the stomach for more than 6 months. Patients should maintain a balanced diet and exercise regularly for effective weight loss...
