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.
Laparoscopic Adjustable Gastric Band：
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 . Doctors can adjust the band according to the condition of the patient… (More)
Laparoscopic Sleeve Gastrectomy：
This surgery is indicated for patients with BMI over 30. Two weeks prior to surgery you are instructed to have only fluid diet and milk supplements. The surgery is performed under general anesthesia. Dr. Wong will make 4-5 small (1-1.5cm) incisions and remove 70-80% of the stomach in order to create a ‘banana’ shaped stomach. The entire procedure last for about one and half hours and patients will be discharged from hospital 3-4 days after surgery… (More)
Laparoscopic Adjustable Gastric Band Plication:
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....
Laparoscopic Gastric Bypass
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...
Non-Surgical Method
Intra-gastric Balloon
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...
