SIBO (Small Intestinal Bacterial Overgrowth)

SIBO occurs when forward gut movement slows down, allowing bacteria to backwash into the small intestine that should not be there. The small intestine houses most of the immune system and is where we absorb most of our nutrients so it is crucial to keep things moving. Forward gut movement of bacteria, toxins, and food is called gut motility. When we have problems with gut motility, we usually have a problem with the migrating motor (myoelectrical) complex also referred as the MMC. The MMC is comprised of cells and nerves that create a series of electrical waves in the gut to sweep stuff out that we do not want in there and moves it down to the colon to be excreted. When the MMC becomes damaged, bacteria can be backwashed into the small intestine and this gives them an opportunity to feast on food. As the bacteria feed, they excrete gas which can cause bloating and abdominal pain. There are three types of bacteria that produce gases: hydrogen, methane, and hydrogen sulfide. Someone with a hydrogen dominant SIBO tends to have more diarrhea, someone with a methane dominant SIBO tends to be constipated, and someone with sulfur dominant SIBO has egg smelling gas and breath. There are two other things that happen with SIBO: 1) Intestinal permeability occurs, also known as leaky gut, leading to food sensitivities. 2) A reduced ability to break down carbohydrates. Slow gut motility gives bacteria time to ferment carbohydrates because they are not broken down properly, leading to more gas and bloating.
