Everyone who is posting here is doing so because doctors haven't figured it out and are misdiagnosing. I posted my observations along with my personal research spanning years on the matter. One of the symptoms everybody is reporting (and I too have experienced) associated with SIBO is malabsorption. There is only one way malabsorption can happen: Hypochlordia/Achlorhydia. How does that happen then? There are only two things that can shut down your gastric acid production resulting in a Hypochlordia/Achlorhydia. One is a valve (i forget the name of it) located inside the body that can malfunction cutting off your gastric acid production resulting in a less than desirable ph. The second thing that can shut down your gastric acid production is Candida. Well if you know oregano oil has strong antifugal properties, then you obviously take some oregano oil and see what happens. What happens is the Candida will immediately retreat from wince it came the intestines.That allows you to determine it is not a malfunctioning valve. Candida is always in your intestines and that is where it is supposed to stay. Your acid production will immediately turn on once you use the oregano oil. In my case, I got caught with a full load of Betaine Hydrochloride pills in my stomach when my gastric acid resumed upon administering oregano oil. That resulted in me refluxing a whole lot of acid. So much so I actually burned my esophagus. It was burned for several days. So now you have established positively that you had Candida. If you have no stomach acid bacteria is obviously free to move upward from the intestines to the stomach where it has no business being. When that happens you're infected (SIBO). The bacteria then proceeds to strip your stomach of it's protective mucus coating inflaming the stomach lining. You now have gastritis as well. The distension people are reporting is swelling from gastritis. You will also see a combination of swelling and bloating at the very same time for different reasons associated with the overall ailment. Sometimes you'll see bloating and sometimes you'll see swelling or both. You must learn to distinguish which is which. This is not that hard. You simply administer the oregano oil and the right antibiotic and you're done.
