When does one undergo a malabsorptive procedure for weight loss? Part 1

-->  The first thing you should know is that all malabsorptive procedures are second choice. You should never ever undergo this procedure as the first surgery for weight loss. These procedures are complex, take a long time and fraught with serious complications. They also cost a lot more than the routine lap band or the sleeve gastrectomy.
 

Malabsorptive procedures alter and divert the digestion process, thus causing food to be poorly digested, incompletely absorbed and the majority is excreted in the stool. Malabsorptive procedure were performed widely 30 years ago but discontinued because of severe complications. The majority of patients did not even live long from the complications. Over the years, surgery has become refined and better instruments are available to perform this surgery. There are several versions of malabsorptive procedures created to prevent absorption of food. The stomach is not removed but simply bypassed using various surgical techniques.
