The gastric bypass surgery is a type of bariatric surgery which aids obese individuals in losing weight fast. The success rate of the procedure is generally high with most individuals losing lots of pounds with relatively less complications. Unfortunately, the same cannot be said for some individuals who for one reason or another fail to lose weight or even gain more weight over a short while. Weight gain after gastric bypass surgery can be attributed to both mechanical and metabolic reasons and requires gastric bypass revision surgery. Read below for most popular revision surgery options.
The metabolic reasons relate to unaltered eating behaviors of the patients with some continuing to consume high calorie meals. Remember that having the surgery does not automatically eliminate your food cravings. The difference is in the restrictions imposed by your doctor that you are required to comply with long term after the surgery, which include exclusion of weight gaining foods, particularly high carbs, and learning to properly combine foods. Having said that, it has been observed that some still gain weight even after resuming proper dietary habits and lack of exercise. As noted, some gastric bypass complications are purely mechanical involving gastric fistula formation and pouch dilation. In all of these complications, the stomach either stretches to its original large size or the portion of the stomach and small intestine bypassed is reconnected.
A top choice for gastric bypass revision surgery is the Roux-en-Y gastric bypass which is mostly performed in patients who have undergone gastroplasty, stomach stapling or gastric banding but more importantly, individuals with low metabolic rate.
In other surgery options, a sclerosant (irritating solution that is normally used to shrink veins) is injected into the stroma (supportive tissue surrounding an organ) connecting the stomach to the small intestine, therefore reducing gastric emptying time.
Other revision surgery options like the ROSE procedure and the stomaphyX reduce stomach size by passing a device trans-orally into the stomach. The stomphyX gastric bypass revision surgery is done through endoscopy to tighten a stretched pouch by means of sutures and fasteners.
An adjustable band can also be placed in the upper portion of the stomach to reduce the size of a previously operated stomach. Lap banding versus gastric banding is currently a hot debate as to which has a higher success rate and therefore does not require a gastric bypass revision.
A complication of most of these procedures is malabsorption of important nutrients like vitamins B, C, D, iron, zinc, and magnesium, which, on their own (with or without procedure), carry a variety of health deteriorating conditions. The gastric bypass vitamins are supplements given subsequent to the development of this complication and are administered through injection or orally.
