Obesity & Weight Loss Treatment

Bariatric surgery is a procedure to aid weight loss. This surgery involves reducing the size of the stomach and leads to rapid weight loss.
It is usually considered when dietary changes, exercise, and other weight loss pursuits are not able to give results.
The most common bariatric procedures are:
Both gastric sleeve surgery and gastric bypass reduce the stomach from its regular size to a small pouch. This causes weight loss due to the following reasons:
The two procedures however differ in the way the new stomach pouch is created.
Gastric bypass is more complicated than gastric sleeve surgery as it is a two-step procedure, while gastric sleeve only involves one step.
Both procedures are done laparoscopically. This involves inserting a lighted scope with a camera called a laparoscope and other tools through several small incisions in the abdomen to perform the surgery.

Gastric Sleeve Surgery (LSG)

During gastric sleeve surgery or Laparoscopic Sleeve Gastrectomy, the surgeon permanently removes approximately 80 percent of the stomach. What remains is a tubular pouch resembling a banana.

Gastric Bypass Surgery (RYGB)

This procedure is also called Roux-en-Y gastric bypass. The surgeon creates a small stomach pouch by removing or bypassing most of the stomach and the first part of the small intestine. The new stomach pouch is reconnected to the remaining small intestine.
The bypassed top part of the stomach is attached to the small intestine further down, so it continues providing the acid and digestive enzymes which eventually mix with the food.
The portion of the small intestine that’s bypassed is responsible for absorbing some nutrients and calories. Following the bypass there is no food passing through it, so the absorption of those calories doesn’t occur which contributes to weight loss. In addition, the rerouting of the food stream produces changes in gut hormones that suppress hunger.

Adjustable Gastric Band (AGB)

In this procedure, a small stomach pouch is created by placing an inflatable band around part of the stomach.
This works on the fact that with the smaller stomach pouch, eating just a small amount of food satisfies hunger and promotes the feeling of fullness. This feeling of fullness depends on the size of the opening between the pouch and the rest of the stomach created by the gastric band. The size of the stomach opening can be adjusted by filling the band with sterile saline, which is injected through a port placed under the skin of the abdomen.
Gastric band surgery can be easily reversed by removing the band.

Important dietary guidelines that one needs to follow after gastric sleeve or gastric bypass surgery:
  • Group 2236 Eat small amounts and stop when full
  • Group 2237 Chew food thoroughly
  • Group 2238 Eat slowly
  • Group 2239 Take recommended vitamins and supplements
  • Group 2240 Stay hydrated by drinking enough water
  • Group 2241 Sip fluids rather than drinking quickly
  • Group 2242 Avoid food that’s difficult to digest
  • Group 2244 Avoid carbonated beverages
The pouch will stretch over time. It’s important not to overeat after bariatric surgery because the pouch can stretch enough to regain the weight lost.
The type of bariatric surgery that’s suitable for the patient depends on various factors such as:

Complications Associated with Bariatric Surgery

Bariatric surgery is a relatively safe procedure.
According to the American Society for Metabolic and Bariatric Surgery, the risk of a major complication is about 4 percent. This is much lower than the risk of developing serious obesity-related health complications.
Some factors that can complicate any surgery, including bariatric surgery, include:
If you are considering bariatric surgery, speak to your doctor about the possible risks and benefits of these procedures specific to your condition.
