Weight Loss Surgery, Obesity & Health
Is WEIGHT GAIN a GROWING concern for you?
Are you feeling frustrated with your current weight? Have you found yourself getting heavier and heavier as the years pass by? Do you have some success losing weight, but find it creeps back on over the years? Perhaps weight loss surgery can help.
If you have had only transitional success losing weight, with the weight coming back on nearly as quickly as you take it off, it is likely time to consider Gastric Weight Loss Surgery. There are 3 main types of Surgery that can help treat Obesity: Gastric Band/Lap Band, Gastric Sleeve and Gastric Bypass.

How Weight Loss Surgery can help improve your Type 2 Diabetes
Obesity related disease has reached epidemic proportions in our society today. Some of the problems associated with Obesity include Diabetes, cardiovascular diseases, back pain, joint pain and sleep apnoea, but there are many other problems associated with being overweight.
Non-surgical modalities of treating Obesity have a place. Yet when we are talking about treating morbid obesity (BMI > 35), a more invasive treatment modality, such as Weight Loss Surgery (Obesity Surgery), becomes a mainstay of treatment.
Surgery by itself cannot be successful unless coupled with sound lifestyle habits.
At Melbourne Gastro Surgery, we pay utmost emphasis on client education and ensuring our clients have adequate support both before and after surgery, such that they can achieve optimal health and maintain it.
We provide below, a brief overview of the various surgical weight loss procedures we offer in our practice.
Laparoscopic Adjustable Gastric Banding
One surgical treatment option for the condition of Obesity is the Laparoscopic Adjustable Gastric Band (LAGB).
- This is a keyhole procedure requiring a short hospital stay.
- It involves the insertion of a silicon ring around the upper stomach.
- This ring holds up the passage of food and creates a small pouch above where it is placed, which restricts portion size.
- With a gastric band or “lap band surgery,” there is also a profound effect in reducing hunger, which is not yet fully understood.
How gastric band surgery works for weight loss:
- Several weeks after surgical insertion, the gastric band is filled with saline.
- This is accomplished by an injection through the skin on the abdomen into a chamber which connects to the band via a tube.
- The saline-filling of the band then places extra pressure on the stomach and starts the process of dietary restriction and weight loss.
Lap Sleeve Gastrectomy Surgery
The sleeve gastrectomy (“gastric sleeve”) is also a key hole surgery performed on the stomach.
- A gastric sleeve is only a portion-restrictive procedure.
- It does not involve any surgery on the intestine, which would make it malabsorptive.
- Sleeve gastrectomy has also been called tube gastrectomy and vertical sleeve gastrectomy.
- It basically consists of converting a stomach that typically resembles a pouch, into a long tube instead; thereby garnering the name “gastric sleeve.”
The sleeve gastrectomy (SG) for weight loss removes three-quarters of the stomach, which provides for quicker satiety (sense of fullness) and decreased appetite.
- The smaller stomach sleeve restricts food intake by allowing only a small amount of food to be eaten at one time.
- The valve at the outlet of the stomach remains which provides for the normal process of stomach emptying.
- Also, the sleeve does not involve rerouting of the intestine, hence there is no malabsorption or dumping syndrome.
ROUX-EN-Y Gastric Bypass
Roux-en-Y Gastric Bypass involves forming a small stomach pouch (about the size of a person’s thumb) which is created using a surgical stapler (1).
- The small stomach pouch restricts food intake by allowing only a small amount of food to be eaten at one time.
- Next, the small bowel is divided about two feet from the stomach.
- One end of the small intestine is brought up and attached to the stomach pouch (the gastrojejunostomy).
- The other end of the small intestine, still connected to the now non-functional stomach remnant, is reconnected to the intestinal tract (the jejunojejunostomy).
- As the name “gastric bypass” implies, following the surgical procedure, food is now routed past most of the stomach and the first part of the small intestine. In addition to restricting food intake, gastric bypass reduces nutrient absorption.
MINI GASTRIC BYPASS
Mini gastric bypass surgery is a short and relatively simple procedure that has been shown by the available research to have low risk and result in good short and long-term weight loss.
Is Mini Gastric Bypass surgery right for you?
As the name suggests, mini gastric bypass surgery is a simplified form of Roux-en-Y gastric bypass surgery (RNY).
A thorough review of the studies that specifically evaluated the effectiveness of MGBP shows that the procedure is shorter, easier, less expensive and has lower risk and equally successful outcomes as RNY.
Even though MGBP sounds like an obvious choice between the two procedures, there are a few significant reasons why this might not always be the case.
1. Mini gastric bypass usually bypasses much more of the intestine than a standard gastric bypass which could lead to more vitamin and mineral deficiencies.
2. Unlike gastric bypass surgery, digestive enzymes and bile are not diverted away from the stomach after mini gastric bypass. This can lead to bile reflux gastritis which can cause pain that is difficult to treat. Bile reflux gastritis may also increase the risk of cancer in the stomach pouch.
3. Not many surgeons do Mini Gastric Bypass Surgery, so it may be slightly difficult to find someone willing to do this.
4. Mini Gastric Bypass would be an option if someone would have had a previous weight loss operation and is now seeking a revisional procedure.
5. More long-term research is needed to solidify mini gastric bypass surgery’s position as a viable bariatric surgery option.
