Types of Bariatric Surgery or Weight Loss Surgery

Lap banding and gastric bypass are the most commonly used Bariatric Surgery or Weight loss surgeries. All surgeries fall into two groups: restrictive and restrictive-malabsorptive.

Several types of weight loss surgeries (Bariatric surgeries) are available. Lap banding and gastric bypass are the most commonly used ones.

Roux-en-Y gastric bypass

Laparoscopic adjustable gastric banding (LAGB)

Biliopancreatic diversion (BPD)

Duodenal switch (DS)

Vertical banded gastroplasty (VBG)- abandoned

Weight loss surgeries (Bariatric surgeries) fall into two groups: restrictive and restrictive-malabsorptive. In a restrictive surgery, the amount of food the stomach can hold is limited and the rate of gastric emptying is slowed down.

Laparoscopic adjustable gastric banding (LAGB) is the most commonly performed restrictive operation. An adjustable band (the lap-band) is used around the opening of the stomach. The band is connected to a reservoir that is implanted under the skin. Injection or removal of saline into the reservoir constrains or loosens the band's internal diameter. The size of the gastric opening can thus be altered.

There are three restrictive-malabsorptive bypass procedures: Roux-en-Y gastric bypass (RYGB), Biliopancreatic diversion (BPD), and Biliopancreatic diversion with duodenal switch (BPDDS). They work by combining the elements of gastric restriction and selective malabsorption.

Roux-en-Y gastric bypass (RYGB) is the most commonly performed and accepted bypass procedure. A small pouch is created in the stomach and it is attached to the small intestine. The procedure can be performed as an open surgery (by making an incision on the abdomen) or laparoscopically (via smaller incisions, using smaller instruments). The surgery usually involves a 5-7 day hospital stay in case of open and 2-3 days in case of laparoscopic procedures. Most people may return to their normal activities within 3 to 5 weeks.

Patients who have an extremely high BMI and are high operative risks benefit from a two-stage duodenal switch (DS) procedure. This includes sleeve gastrectomy where the size of the stomach is reduced to a narrow tube. This procedure is however not as commonly done as the previously mentioned ones.

In addition to my other letter. I also am having trouble with a foot that is going numb. Neruopathy from lack of vitamin b-12 and I am having trouble with my eye sight. I have double vision. they are testing me for mysethina gravis and MS. I am suffering daily all I believe due to the gastric bypass surgery.. I maybe wrong but I was without any of these problems before the surgery.. My dr. once said for being 333lbs. you'd never know it looking at all of my health issues or lack of and lab work. my health status was great I only was fat...I'd do anything to not have done this surgery and have my healthy fat life back...I can't believe I did this surgery so I could do more funny, I suffer daily in pain, losing my teeth, losing feeling in my foot and most of all I have to close my left eye to see or I'll see double vision. that takes away your independence.. OH what I wouldn't do to be a healthy fat functioning independently daily....
