Did Someone Say Pyloric Valve?

 Excuse me, but is all of that going to be on the TEST?

    

Banded 10 years & maintaining my weight loss!! Any questions, message me.

Since my pyloric valve was useless due to vagus nerve damage I say good riddance!

Also, I don't dump or have RH

But of course everyone has their own opinion and their own story. Enjoy your war :)

Ah, so people with the Band (who have a pyloric valve) should do better than people with RNY and not have any problems?  "Fascinating, Captain..."

Warmly,

Not quite, there are lots of people with a pyloric valve who have dumping and HR.   However, I never hear bandster complaining of such and I never experience dumping as a bandster, but do as a sleevster.

 That has already been stated a few times.  My links are mainly about the correlation between loss of the pylorus and dumping/RH specifically.

I also am advocating for the preservation of the pylorus, not specifically via one surgery.  Again 3 of the 4 major WLS available preserves the pylorus.

I am simply making the information available to those doing research.

Thanks to everyone for bumping my thread to help me get the word out.

Have a good evening.

There is no absolute correlation between loss of the pylorus and dumping/RH specifically. The above poster had the VSG thus has an intact pyloris and still has dumping. If there was an absolute correlation then ONLY the RNY would/could have dumping/RH. Therefore there MUST be at least one more factor involved.

 That is why I encourage pre-ops to research and come to their own conclusion. I believe that there are many reasons for dumping and RH with or without having had any surgery.  But from the information I have been reading, purposeful removal of the pyloric valve somehow greatly increases the chance of this happening.

Could you post the links showing a greatly increased chance of RH with pyloric valve removal vs. not removing it.

 I am only advocating the preservation of one's pylorus.  I do not care which surgery one ultimately decides to have.  But, yes, 3 of the 4 major WLS available does keep the natural stomach and preserves the natural function of the pylorus. The band, VSG and DS.  I am just making the information available for pre-ops to consider during their research.

Aw, GG, you are upsetting the RNYer with your inconvenient truths and logic and all that edumacational nonsense.

* A few normal people get dumping symptoms very very occasionally (I personally can recall 4-5 times as an adult that I had weird symptoms after eating something that were EXACTLY what I have read is involved with dumping)

A vanishingly few normies get RH.  Most of them have pancreatic tumors.

* A few non-RNY WLS patients have such symptoms - whether caused by their WLS or not, is hard to tell, because it is not very common, and might have happened anyway, as it does to some normies.

* VERY VERY few non-RNY WLS patients get RH.

* LOTS of RNY patients get dumping.

* A significant number of RNYers get RH.

This does NOT mean that losing the function of your pyloric valve inevitably CAUSES either dumping or RH - however, it DOES mean that losing the function of your pyloric valve VASTLY increases the risk of dumping and RH.

Perhaps that RNYer needs to have her DH explain to her the logic of medical research.  Just because she keeps staying the correlation isn't ABSOLUTE doesn't mean it isn't a cause.

Most people who smoke DON'T GET LUNG CANCER EITHER.  Doesn't mean smoking doesn't cause lung cancer.

PS: The gastric bypass surgeons have known about this for THIRTY YEARS:

Altered glucose tolerance, insulin response, and insulin sensitivity after massive weight reduction subsequent to gastric bypass.

Halverson JD, Kramer J, Cave A, Permutt A, Santiago J.

Abstract

We have studied an otherwise normal group of morbidly obese subjects and compared them with patients who had experienced massive weight loss after loop gastric bypass. Compared to normal controls (NLCs), morbidly obese control patients (OBCs) had abnormal glucose tolerance curves (after glucose ingestion), elevated basal insulin levels, and increased plasma insulin concentrations, suggesting insulin insensitivity. The latter has been corroborated by the measurement of decreased insulin binding in these patients. Postoperative (PO) patients were hyperglycemic after taking oral glucose, but all PO patients had a rapid decrease in plasma glucose concentration, half reaching hypoglycemic levels. PO basal insulin levels and insulin receptor number were not statistically different from those in NLCs, indicating up-regulation of insulin receptors (and therefore, increased insulin sensitivity) postoperatively. Hyperinsulinemia seen in the PO group (greater than that in OBCs, P less than 0.001) after administration of oral glucose occurred simultaneously with a doubling of plasma concentration of gastric inhibitory polypeptide. Massive weight loss in patients after gastric bypass was accompanied by an improvement in insulin receptor number, basal hyperinsulinemia, and glucose tolerance. In addition, postoperative patients demonstrated symptomatic reactive hypoglycemia which may have resulted from the hyperinsulinemia seen subsequent to ingestion of glucose.
