Your gut microbiome consists of billions of organisms from many thousands of species. Your gut biome consists of about three pounds of tiny single-celled microbes living in your gut which have a profound effect on your health.
These gut microbes can be grouped by phylum into firmicutes, bacteroidetes, actinobacteria and proteobacteria, fusobacteria and verrucomicrobia. The population ratios of these organisms are determined by our exposure to the environment. And, the diversity of bacterial species and the ratios of these organisms can determine your health are associated with various negative bodily conditions, including obesity.
Your body is covered with microbes from the outside on your skin into your mouth and all along your gastrointestinal tract. About 700 bacterial species may live in your oral cavity alone. Some of the factors that determine the makeup of your body’s microbiome are:
Leaky gut syndrome refers to a set of symptoms that are associated with a “leaky gut.” What we often call “leaky gut” is more scientifically labelled as “intestinal epithelial hyperpermeability,” “intestinal tight junction malfunction” or even “compromised intestinal barrier function” by the medical community.
The gut is supposed to allow absorption of water, small ions and nutrients into our blood system (the gate function). It is also supposed to prevent other material in your gut from entering the blood stream (the fence function).
The barrier consists of a single layer of cells (intestinal epithelial lining) and the secretions of those cells. The cells are bound together by “tight junction” proteins. But, when this barrier become damaged, the undigested food as well as potentially toxic microbes and microbial products can enter the blood stream.
