Brief Summary   Synbiotics may have a particular application in elderly populations, especially in terms of protection against infections, inflammation, oxidative stress and  also in the prevention of several age-related diseases. 
Synbiotic agents along with vildagliptin reduce the glucose level, inflammation and oxidative stress in geriatric population  with Type 2 diabetes mellitus and also synbiotics potentiate the action of DPP4 inhibitors 
Metformin is the conventional drug irrespective of age group and it prevents the gut leakage and reduce the gut inflammation.
The role of synbiotic agents along with Vildagliptin and Metformin in  geriatric population  with Type 2 Diabetes Mellitus is not done.
