Patient Selection for Bariatric Surgery or Weight Loss Surgery

Selection of Patients

Patients must meet the following criteria for consideration for bariatric surgery:

BMI >40 kg/m2 or BMI >35 kg/m2 with an associated medical co morbidity worsened by obesity

Generally when a person’s weight is 220kg or over, they are considered for this surgery.

Dietary therapy has failed to achieve results

Mentally (psychiatrically) stable without alcohol dependence or illegal drug use

Fully informed about the operation and its consequences


No medical problems that would possibly prevent survival from surgery

Certain other factors taken into account include:

 If a person is obese for at least 5 years

 No previous history of alcohol abuse

 No history of depression or another major psychiatric disorder

Age is a controversial area for selection of patients for the surgery. Food and Drug Administration (FDA) approved LAP-BAND for use in patients 18 years and older. The age of 60s is generally set as a cut off for performing gastric bypass. Increasing experience will be required to decide what type of surgery benefits which age group.

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....
