A new study released online January 27, 2010 demonstrates that compliance with nutrition is a challenge for many bariatric surgery patients. The study, titled Nutritional and Pharmacologic Challenges in the Bariatric Surgery Patient, looked at bariatric patients admitted to a single hospital years after their bariatric procedures (admissions for other causes).Researchers evaluated what they were doing for supplementation at the time of admission and compared this to current ASMBS guidelines.
Most of the patients were 3-7 years post-op, 87% were roux-en-Y gastric bypass. On admission only 33% were taking a multivitamin and only 5% were taking B12 . Problems were also noted with iron, calcium, folic acid and vitamin D supplementation. In addition, researchers found numerous medication errors, the primary problem being the use of slow releasing medication forms in patients with malabsorptive procedures. Overall, this study points to the continued need for both bariatric surgery patients and healthcare professionals to be better educated on appropriate nutrition and medication protocols.

So, people do not take their vitamins. We knew this. "They are yucky! They are expensive! My labs are fine! I had surgery a long time ago, I'm fine! I forgot!"
Now, I was not aware that extended release meds were a no-no. I take one. I specifically ASKED the doctor about that. "Don't worry about it." (Is this why I still have issues?) So, I need MORE information, please!
Which took me approximately five seconds to find. @@ How do I not KNOW THIS?! And, further, why am I prescribed it?
Reductions in drug absorption are more frequently encountered in patients who have had combination restrictivemalabsorptive procedures. Decreased intestinal length and surface area lead to the reduced absorption of extended-release drug preparations because these formulations are absorbed over 212 hours.[27] The reduction in functional intestine length makes it likely that extended-release preparations have passed through the gastrointestinal tract before absorption is complete. These same principles can also apply to delayed-release and enteric- or film-coated product formulations. [28] To overcome this problem, the immediate-release dosage forms should be substituted, which could require increased frequency of administration.
