I've got this part from Dr. Teitelbaum. I was wondering if anyone tried Pepto Bismol, because in my country it isn't freely available and i think in the us it is? So anyone? What Can I Do Now? By Jacob Teitelbaum link Testing I suggest that you use your nose. Increased gas is common in CFS from many causes. Candida overgrowth is usually not associated with its having a foul smell. If your gas smells awful (in layman's terms, "farts that are silent but deadly" and not always silent), you probably have bacterial overgrowth contributing to your CFS. On the other hand, it doesn't mean it's dangerous. If it did, men in general would be in deep trouble. Treatment This research is fairly new, so I don't think anything different needs to be done yet. The approach below, however, is reasonable if gas that smells like rotten eggs is a part of your symptoms: 1. Try using Bismuth subsalicylate (BSS). This is commonly known as Pepto Bismol. Each tablespoon or chewable tablet contains 262 mg, and it aggressively soaks up hydrogen sulfide and pulls it out of your body (by turning the hydrogen sulfide into bismuth sulfide). At the same time, it has antibacterial activity that may kill off both the unfriendly bacteria and the biofilms they live in. One to two tablets 3 to 4 times a day will be enough (adjust the dose so that the gas is not too stinky). Give it a 3 to 4 week trial and see if it helps. Then post your results on our community bulletin board and let us know if it helps you. The concern is that the Pepto Bismol may also kill off some of the healthy bacteria, so I would stop it after 3 to 4 weeks. Warning it is normal for Pepto-Bismol to turn your stools a black color. There appears to be a striking dose-dependent response with BSS: 400 mg / 100 g of dry food completely suppresses cecal hydrogen sulfide release in rats, whereas one fifth of this concentration has no demonstrable effect. What this means in English is just taken enough Pepto-Bismol to keep the flatulence from having a nasty smell. 2. Similar to bismuth, zinc acetate binds hydrogen sulfide. Zinc deficiency is common and causes immune dysfunction in CFS and fibromyalgia, so taking 25 mg a day of zinc is helpful overall. More than this can be toxic when taken long-term however. 3. Increase the intake of probiotics (healthy bacteria). I recommend those that come in "pearl form" as otherwise healthy bacteria tend to be destroyed by stomach acid. I recommend Acidophilus Pearls or Probiotic Pearls 2 twice a day for five months and then one daily.
