I am pre-op and read something I hope is not true..

This is what I just read on OH.  Can a Vet give me input on the part about bone disease?  Also is  it a good idea to have a baseline bonescan before surgery?  Thanks so much for any info.

"Gallstone formation occurs in ~30% of the population after malabsorptive surgery; metabolic bone disease occurs in more than 70-80% of the DS population after surgery.
In fact, markers of bone breakdown are evidenced as early as 8 weeks after surgery... they should consider the risk:benefit ratio."

This is why it is important to be very aggressive in keeping up with your supplements and your labs. 

And yes, it is a good idea to get a baseline bone scan before surgery.

Where did you get this **** from?

Gallstones can happen after ANY weight loss surgery - especially with the DS, since the gallbladder serves NO useful function after the surgery (you don't need to have a bolus of bile delivered in time with a large fatty meal anymore), most surgeons remove it when you have surgery.

As for a 70-80% "metabolic bone disease" number, I don't know what they mean by that term, and I don't believe it anyway - I've never seen anything like that in 8.5 years on OH.  Look at THIS instead:

Diet-induced weight loss by itself is known to be associated with reversible bone loss.8  Metabolic

bone disease is associated with Crohn’s disease and the other severe malabsorptive states such as following JIB.9  Available studies of nutrition following biliopancreatic diversion (BPD), an operation combining a limited gastrectomy with a short common channel, differ on the short- and long-term instances of morbidities such as metabolic bone disease.  Compston et al metabolic bone disease after standard BPD with a 50-cm common channel, although vitamin D levels were normal in all patients.  Marceau et al11 found that bone itself was relatively tolerant to the metabolic changes due to BPD performed with a 100-cm common channel, and that bone loss at the hip depended upon albumin levels and protein nutrition.  Hamoui et al12 found that the length of the common channel in the DS influences hyperparathyroidism  and out-of-range calcium metabolism values.  Parada et al13 reported 53% abnormally elevated  PTH at 18 months following Roux-en-y gastric  bypass, indicating that the alterations in calcium  metabolism after LapDS are not unique to the DS.  Instead, clinically significant calcium deficiency seen after both procedures may derive from the duodenal exclusion from the food stream, as well as the overall reduction in dietary calories and nutrients, common to both  procedures. In contrast to calcium, Vanderhoof et al14 found that zinc absorption is not impaired in the absence of pancreatic exocrine secretions. Since the DS entails a longer common channel than the BPD, bone changes after the BPD may be more pronounced when compared with the DS.

Conclusion

Laparoscopic duodenal switch for morbid obesity affords the absence of general electrolyte or nutritional deficiencies, available effective correction via oral supplementation if indicated, and superior sustained weight loss and quality of life.

 

Conclusion (from the Abstract): LapDS is not associated with broad nutritional deficiencies. Annual laboratory studies, which are required following any type of bariatric operation, appear to be sufficient to identify unfavorable trends. In selected patients, additional iron and calcium supplementation are effective when indicated.

I just love you, Diana! You always back your **** up. I'm not as computer savvy as you and LOVE it when you help us out with real data! I understand why the OP is scared and hope that your response helped. I know I'll be bookmarking it for future usage! Thanks for all you do, in your own time. You are so important to us! I'll quit kissing your ass now and go on about my buisness. Just thought it was time to say Thanks!!

Aw shucks - it's just that I HATE HATE HATE it so much when I see LIES like that being told and left unchallenged.

I agree with Scoob.  I follow you and Elizabeth all over this site because I know I am going to learn something.

Thanks D.  That's a good one.

Agree----thank you Diana!

Anytime there is rapid weight loss(surgery or not) there will be gall bladder issues...pregnancy is usually a trigger as well. Celiac disease(malabsorbtion due to damage in the digestive tract) affects the gall bladder too. How many overweight people have been living with with malabsorption from gluten sensitivity for decades before finally getting WLS?....probably more than the medical community/weight loss industry would ever care to confess to publicly(cure most of our ills with a simple change in diet? yeah that's not going to happen..there are pills to sell dammit!)...the days are already numbered on that gall bladder before they even get WLS. By time too many people get to the point of WLS being the only option to lose weight...the gall bladder is already toast.

As far as the bone disease? Again celiac could be a culprit...how much of an issue was it before WLS? It's not like celiac screenings are standard for overweight/obese patients..most doctors bru**** off, laugh, make a face...mine did ....they offered  me prozac and diet pills instead of listening to my concerns and considering the possibility that a fat chick could be malnourished.

The only time doctors are concerned about malabsorption/malnutrition in overweight patients is after surgery....start testing people for celiac disease at regular intervals starting in early childhood ..maybe we can get to the point where many people won't jack up their metabolism eating doctor recommended wheat breads and heart healthy cereals forcing them to go to the extreme of WLS to save their lives....it's nutz. The first thing they tell you in your post diabetes dx nutrition class is to get rid of all the bread and cereal...my poor FIL was so confused...they changed the rules on him after the damage was already done. Why wait? Why do  we teach kids the evil back-assward food pyramid in school?

Sorry..I know that I'm ranting....I could have been dx'd at 5(hindsight is always 20/20)...instead I dx'd myself in my thirties and chances are my doctors would still assume I am full of **** desperate to blame my weight issues on anything but my own self control....grrrrrr. I will fear their statistics once they start tracking stats before surgery and provide a side by side comparison.

 My insurance allowed for Gall Bladder removal during surgery.  I haven't missed it one bit since.
