Sorry to hear about your challenges. In a quick response to the issue of "wind", I did get a simple resolution-BUT, please be sure to ask your physician first to determine if this is all right. I use an over the counter chewable pill called Devrom. It is bismuth subgallate. I was told this was the same as Pepto Bismol- not so much. I found immediate relief of the smelly part; it does not control gas- that is some other digestive function. I get it online via amazon and it is very affordable. There are several variants of the bismuth subgallate, but I find that Devrom works best for me and choose to leave well enough alone!!
I also get the chewable version as it seems to work with all the other digestive complexities from my gastrectomy.
I have a sub-total gastrectomy, which means almost the entire stomach was removed as a result of two failed surgeries to correct acid reflux- I can give more detail about this but my surgery was not for weight loss, however it did certainly result in weight loss.
The gurgling I found to occur was very prominent early after my surgery– was not the old "stomach growling" (no stomach!) but longer in duration, and certainly louder. I had to share with friends, colleagues, supervisors etc that it was an artifact of the surgery and not a call for food. I do need to exercise care about "slippage" and choose to excuse myself from an area just in case. I learned that since the stomach completes a major part of digestion as a result I do have some amount of undigested food getting through. Just needing to slow down, way down, the eating/chewing processes.
In terms of Devrom usage, I take three per day, one in the morning before breakfast, one around lunch time and one usually after dinner. That's the good part-staying on this routine has all but cleared up the smell. However, if I miss one, game over. I do not double dose- just get back to the schedule ASAP. To that end, I always carry pills with me- and I usually carry 3 or 4- why? Because I cannot afford to lose one or drop one is a bad place- redundancy x 2!
And the last place I want to be unpopular is in an airplane as I travel quite a bit.
I have been so pleased with the results of Devrom I am glad I found it- I always order 2 bottles at a time so I am never without.
What long answer to your question- I hope this helps.
My only other caution: I had some dental work done and the dentists gave me an antibiotic that I later found our I did not need (no aspersions on the dentist). The antibiotic pretty much destroyed the little gut bacteria I had and the odor was magnified beyond belief- needed to get some serious doses of probiotics and these corrected everything- these were very short term. I no longer take those.
Best to you- wish I had known some this before my gastrectomy, however can't rewrite history- I am happy to share my experiences with others so they may not have the same challenges–no stomach is challenge enough! As aways, keep a sense of humor- it does help in some odd way.
