Gut Microbes may Dictate Terms

There has been a lot of interest in the microbial environment in the gut that may influence the health of human in various ways.

Human gut harbours trillions of microbes. The friendly ones do a lot of good for the individual, starting from synthesis of vitamins to digestion of certain food matters. The gut microbial system typically divides the entire population into three different categories.
Several researches find link between health and gut microbial flora. Amongst them;
  • Atherosclerosis; bacteria from oral sepsis have been separated from the atherosclerotic plaques. Break down product of certain fatty foods by gut bacteria produce trimethylamine which in turn is converted into trimethylamine N-Oxide by liver, which finds its way to blood vessels and contributes to plaque formation in blood vessels.
  • Irritable Bowel Syndrome; has been successfully treated by certain antibiotics and some group of bacteria have been held responsible for its development.
  • Dental caries; typically is the result of pathological lactobacilli.
  • Peptic ulcer; has been associated with presence of H. pylori, and being treated with suitable antibiotic combinations successfully.
  • Non-alcoholic fatty liver disease,  
  • Insulin resistance and Diabetes II,
  • Cancer of stomach has been linked to the presence of H. pylori.
Scientists are finding ways to manipulate the microbial environment by gut friendly microbes to achieve good health. However, more research in this field is required to definitely blame the gut microbes for bad health.
