However, RNYERS loss the ability to malabsorb food about 2-5 years out. The only thing they permanently malabsorb is vitamins. Trying to correlate RNY results to DS results is like comparing apples to oranges. Both are fruits, grow on trees, and have seeds but that’s about the end of their similarities.It's a difficult read, but in essence the author takes apart a study on RNY pre and post surgery..
I think this will apply to DS as well because the underlying physiology, delivery of undigested fat to the large colon, is similar
Most interesting thing I found was urine oxalate( which tracks with kidney stones) is less sensitive to diet than before... the big driver is diet fat... go figure... we ( DS) should all be on low fat diets

Low fat for a DSer is way different than for normal humans. If I ate low fat, I’d end up with colorectal surgery.
And while we are obsessed here with our innards, honestly most DSers don’t have issues with kidney stones. The ones who do are very vocal.
On the boards for 20 years.... Also met about 8 DSers in Spain.I must travel with a different crowd, I only know one women who has had bariatric surgery,RNY, and that's because she worked with my wife.
Off topic, but how did you meet so many people who had DS?
I missed you Spiky !! Your humor is a damn riot.Vocal DSer here! My urologist says that stones are not uncommon w/bariatric surgery.
HOWEVER, my weirdness is MY weirdness and it exists in addition to the NORMAL bariatric stuff.
To wit...I seem to have an underlying kidney issue which is PROBABLY exacerbated by my malabsorption of calcium. And, cuz I’m so cute, I have a LEFT KIDNEY PROBLEM...not a systemic issue, which it would be if it were all the fault of the DS. I keep growing mega-stones in my left kidney and none in my right kidney. So, it’s almost all geography, barely any chemistry.
Which means...I had a ureterscopy w/laser blasting and all in Jan 2018, and he got them all...but by May of 2019, I needed a repeat, and he got them all...but it’s November and I have another 7mm stone...in just six months.
Our current plan? Have another ultrasound in Feb. If it’s still 7mm, we wait and watch. If it’s bigger, we go in again.
As an aside...my urologist, bariatric surgeon and GI doctor are all Armenian. So today, at the uro’s, I said that I thought it was notable that I have three Armenian doctors who don’t want me anywhere near their grape leaves. Uro said, “No! You have three Armenian doctors telling you to eat meat!”
(As she plays a doctor on the internet...) NO! That’s bass-ackwards (if we’re talking calcium oxalate stones, which are the most common)! Most calcium oxalate stone people are told to consume MORE calcium!I missed you Spiky !! Your humor is a damn riot.
So last week I had ultrasound of kidneys and bladder. My symptoms were like bladder spasms and dull ache in lower pelvis. Urinalysis showed no bacteria but mucho blood (not visible). So, I'm still waiting for official report and game plan but I'm told I have a left kidney full of stones. WTF? I'm afraid to take my calcium supplements till I know what the heck happens next !!! Actually I'm scared and quit all my vitamins in fear !! How do I find out the composition of my renal rocks???
i had my DS in Jul2018, and have kidney stones. to the defense of the DS, i had kidney stones prior to having surgery.. for about 10 yrs. a couple mths ago in Oct, I had to have surgery to have a stone removed from my left kidney that was stuck in my distal ureter, and urologist also removed the other stones in my left kidney - it had been there for a while and was starting to grow into my ureter. i also have stones in my right kidney (like 3-4 small ones according to the ultrasound), but those were left in. after having my urine collected over a 24 hr period, i have tons of sodium being excreted in my urine, and tons of oxalate, and calcium too (if i rem right). so was just put on potassium citrate and told to lower my sodium to 3g/day, added vitamin b6, and drinking 100oz of lemon water.... AND to omit high and moderate oxalate foods. i also have to meet with a nephrologist and have a CT of my left kidney to see why i still have residual swelling. i also want to add too that i have added in foods that i know i shouldn't - chips, oatmeal, chocolate, wheat bread. but i'm not sure that these "no-no" foods are solely the cause. four months after my surgery, when i had my bloodwork done, i had a moderate amount of oxalate crystals in my urine, and within a week after this, i passed a stone - and i was eating nothing but protein and fat and plain water. i'm hoping i can get this situation under control because i don't want to continue to have issues with my kidneys
I'm another stone former that was this way long before my DS, but the link from Spiky above pretty much sums up what my nephrologist says, as well as my having low citrate. I take a prescription for raise the urinary citrate to make it harder for stones to form in the kidney. My kidney stone issues were likely hereditarty, and several generations have had them, and have even died from complications with them, but I was told my DS most certainly exacerbated them. We know more about them than previous generations, and the the increase in the calcium (ALWAYS taken with any food eaten) and the potassium RX have made a huge difference in reducing mine (and the low oxalate diet did absolutley nothing to help).
