and so on. The alterations in GM is very susceptible to changes in our diet and environment which makes them vulnerable and ultimately ends in the incidence of diseases. Reversal of the GM alterations can restore the normal physiological functions and health. Hence further investigation is required in order to get a detailed scenario of the composition of various GM and their detailed function. Scrutiny of the composition of the GM and the change in their population in various metabolic disorders can create new avenues in finding out the treatment for those diseases. Deeper insights in the composition and function of GM can also provide more ideas for development of various techniques and drugs for the enhancement of the GM for better physiological responses and treatment of diseases.
