What is he difference between RNY and Duodenal Switch? I'd like to hear from people who have had the DS.    — Rebecca B. (posted on October 13, 2002)

The DS has two components, stomach reduction and malabsorption. The surgeon removes the outer curve of the stomach, leaving the pyloric valve intact while reducing the overall size of the stomach. Thus you have a normally functioning stomach that controls the way food is released into the small intestine; no 'dumping' or complications such as stoma strictures, blockages or staple line disruptions or leakages. The malabsorption component is similar to the RNY except that the amount of intestine that is 'bypassed' is individually determined based on a percentage. RNY has two types, distal and proximal, which are fairly standardized. The DS bases the amount on things such as starting wweight, age, genetics, etc. I have 8.9% "common channel" for fat absorption, which is very extreme. At present, I eat about 2-3 cups of food and feel satisfied. I take calcium, multivitamin and Vitamin A and D supplements in high doses to compensate for the malabsorption. I am in great health and have lost 255 pounds in 2.6 years. I poop after every meal and yes, they are a bit smellier than 'normal' poop, but it is manageable. I get gassy after eating certain foods, similar to prior to surgery. For more information on the DS, go to www.duodenalswitch.com. I wouldn't have any other bariatric surgery and I am very satisfied with the results. Good luck to you!
