Everything has been going well for me but yesterday morning I woke up with what at first felt like hunger pains for the first time. I had oatmeal and a protein shake and a couple hours later I was feeling better. By the afternoon I had developed a pain in my lower left back and my stomach nausea had returned. Having experienced this once before I realized it was kidney pain. When I woke up this morning the stomach nausea was gone but the kidney pain was still there. When I went to the bathroom the volume was very low which is the dead give away that it was a kidney stone.

I was able to get in contact with my doctor and he confirmed it sounded like a kidney stone and to try to flush it out. I wasnt as diligent this weekend in getting my fluids and now I am paying the price. Its a wakeup call to me on the importance of staying hydrated.

Has anyone else experienced kidney stones post op?

I'd be surprised if it was related. I know some people develop gallstones after a quick weight loss (thus, they put a lot of us on ursodiol after surgery), but I haven't heard about people developing kidney stones. Still, you're right - being well-hydrated should help. Sorry you're going through this - I've heard stones are really painful!!!

According to the Internet, bariatric surgery produces an increased incidence of kidney stones.

Calcium and oxalate are naturally absorbed by the gastrointestinal or GI tract. Following weight loss surgery, patients tend to absorb less calcium from their GI tract. The end result is that higher levels of oxalate tend to occur in the urinary tract. Under the right circumstances, the oxalate will form crystals, which in turn can aggregate to form kidney stones.

So you are right to make sure that you stay hydrated and meet your daily fluid requirements. Over the years there have been several individuals on this site that have reported getting kidney stones after bariatric surgery.

Oxalate stones are a potential side effect of gastric bypass surgery. Consuming water throughout the day, limiting your sodium intake, and eating a diet rich in plant-based protein are all healthy strategies that can help you manage your weight, and prevent kidney stones.

Good to know - I hadn't heard about that. Thanks!

And Kidney Stones are a miserable thing to have at any time, I would think worse when you don't have all your strength back from major abdominal surgery! Yeeouch!

Im 8 weeks post op and for almost 2 weeks ive been going thru kidney stones. I actually had a stent placed then surgery a week laterfinally got stone but stent back in to help with healing! I get about 90oz water a day but doc said all the calcium we have to take may add up!

That's something we don't readily consider, keep the fluids going in, when you're producing pale and plentiful urine, you're much less likely to pass sand, gravel and stones!?
