Hello all, I am relatively new to the group and hope I am following proper protocol in posting this query. My pain management (PM) physician disagree's with my assumption (anecdotal as it is - without any published data to back my idea up) that like supplements, non pain related medications and the like are not absorbed as readily or in the amounts of the meds and therefore usually need an upward titration to compensate. I was told (pre-surg) that for the rest of my life, this could be an issue and I have to eat slightly more protein than non-bypass patients, take a pre-natal chewable vitamin every day (I am a MALE and YES I said pre-natal), and 2000mg calcium per day. After mentioning my surgery to other non-pain related physicians, the seemed to understand the concept and agreed to titrate up if necessary and this has worked well, except with my pain management physician even after complaining that I was experiencing significat and distracting pain to the point where I could basicly not do more than lay in bed all day and night (Laminectomy with fusion L5S1, diffuse disc bulging and pain, herniated cervical disc). After a psyhiatric review by my pain-doc's psychologist, he (Psychologist - yes I know he cannot render medical opinions) seemed to agree that malapsorption could be in issue and that it should be addressed by my pain doc and there are plenty of different meds at my PM's disposal to try to get me moving more toward a less painful life and be more productive. Good for me all around he thought. My PM told me he disagrees with the absorption problem and said nothing further and did not adjust my meds at all or offer any alternative. He has prescribed me Duragesic patches and roxicodone for break through but it just never seems to dull the distracting burning/aching that has screwed up my life. My question is, does anyone know of any medical literature or some-such that would confirm or suggest that post gastric bypass patients have oral medication absorption issues? Thank you for considering my Information Request. Moe "I want to shine on in the hearts of man, I want them eating from my broken hand"
