Recent research has shown that there is a link between metabolic diseases (like diabetes, obesity and cardiovascular diseases) and bacterial population in the gut. The results of such studies indicate that Type 2 Diabetes Mellitus (T2DM) in humans is associated with compositional changes (dysbiosis) in intestinal microbiota. It has been observed that populations of certain bacteria are increased (harmful) while some of others are reduced (beneficial) in T2DM. Hence, an entirely different approach for management of T2DM may be made by administering the beneficial bacterial species as a probiotic.
