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.
