whipple operation for duodenal cancer, psyllium, and flax seed meal. After my cancer operation in 1991 I suffered terrible flatulence - gas in both directions. It was a difficult time for several years - my doctors prescribed pancreatic enzymes that were useless.
Eventually I realized because of the removal of my duodenum, digestion of oils and fats especially was impeded. I was better avoiding all oils and fats, but that was not a long term solution. My triglycerides were elevated and I was slowly depleting my essential oils and drying out based on my skin condition. Adding back essential oils (flax mixture) brought my tryglicerides back to normal in the first week but my original gaseous problems were still there.
Eventually, after 10 years or so, I discovered psyllium seed that cured the condition entirely when I added it mixed in water before major meals - or before oily or in some cases even when I indulged in pig-out foods. My movements still were not perfect and recently, only the last 5 months or so I discovered flax seed meal or powder is even better - not quite as course in elimination and adding substantially more vitamins and nutrients as I understand it.
Either of course would be a life saver for anyone else out there who's an outcast because of runaway flatulence.
