The name of the surgery I had was Duodenal Switch. I did NOT have gastric bypass (known as RNY or Roux-en-Y). The Duodenal Switch and the RNY both combine a restrictive element and a malabsorptive element, but that is where the similarities end.
In the Duodenal Switch, 85% of my stomach was removed. This is the restrictive element. I can only consume a small amount of food at a time. The most important thing to me regarding this surgery is that my remaining stomach remains a stomach. I do not have a "pouch" like bypass patients. I have an honest to blog functioning stomach with acid producers and a pyloric valve (not a stoma). It churns and gurgles and does all the things a stomach should do.
The second part of my surgery causes the calories I DO consume to be malabsorbed. The intestines are rerouted so that the food I eat does not have as long of a journey through the small intestine (where all nutrients as well as calories and fats are absorbed). I absorb about 20% of the fat I ingest. Pretty neat, huh? On the down side, it also means I absorb significantly less vitamins and other nutrients. I have to load up on protein and vitamins and minerals in order to not become malnourished. Tit for tat, as far as I see it.
So what does this all mean?
- Because I don't have a "pouch" I can consume slightly larger quantities of food than a bypass patient.
- I NEED to consume larger quantities of nutrients because my malabsorption is higher than that of a bypass patient.
- I will not get "dumping syndrome" if I eat sugar or fat. However, I will pay for overindulgence with very unpleasant bathroom emissions.
- I have an extremely good chance of maintaining at least 85% of my weight loss after 10 years (as opposed to other weight loss surgery outcomes).
- I HAVE FRANKEN-GUTS!!! Sorry, but that amuses me to no end.
