When do we consider surgery?
Patients considered for weight loss surgery must be at least 100 pounds overweight and have a BMI of at least 37 or a BMI of 33 with associated comorbidities such as hypertension, diabetes, or sleep apnea etc. Weight loss surgery is definitely not for those who want a quick fix or who simply don't want to diet. So a history of documented dietery weightloss attempts is asked to identify patients with lifelong commitment to follow-up care and extensive dietary, exercise and medical guidance.
Surgical: We recommend considering surgical weight loss options for these patients. In fact, the risk of death from not having surgery is greater than the risks of surgery ( see Obesity related conditions)
Types of Bariatric Surgery
|
Restrictive procedures make the stomach smaller to limit the amount of food intake giving early satiety and fullness |
|
Restrictive and Malabsorptive techniques reduce the amount of food intake and also limit the length of intestine that comes in contact with food so that the body absorbs fewer calories |
Gastric Banding
The Adjustable Gastric Band is a hollow band made of sylastic which is placed around the upper third portion of your stomach to create a small stomach pouch that initially holds 2 ounces of food, and eventually holds up to 4 to 6 ounces. Creating this restricted stomach space in the upper portion ofthe stomach causes a longer lasting feeling of fullness because the nerves that signal the brain when you're full are located in the upper area of the stomach. The band further works by slowly allowing the food you eat to be released into the lower portion of the stomach for digestion. Patients are allowed to return home the same day or sometimes require to stay overnight with release from the hospital about 24 hours post surgery. This can be done in the outpatient department during followup visits.
Adjustment:
Immediately after surgery the band is empty. About six weeks after surgery, or whenever a plateau in weight loss is reached, the surgeon may add a small amount of saline in the band. While the band can hold about 4 to 5 cc's of saline, only small amounts of saline are added each time.
This can be done in the outpatient department during follow up visits.
Advantages of gastric band:
|
it can be adjusted to increase or decrease restriction. |
|
Surgery can be reversed. |
|
Digestion and absorption is normal. |
Gastric bypass operations
Gastric bypass procedures are combination operations. That is, they combine both restrictive and malabsorptive techniques:
|
Create a small stomach pouch to restrict the amount of food you can eat. |
|
Construct a bypass of the duodenum and other parts of the small intestine to cause malabsorption. |
