I get a stomach upset every once in 6 months and it drains me out. When I am sick I am usually given antibiotics to treat the infection. I hate falling sick. I try to include lot of buttermilk, fiber and fruits in my diet yet after all the preparation to keep my body healthy I fall sick. I took an appendix scan but it says I don't have any problem. Before I got married I was 61 kgs now I am 66kgs. My height is 173 Cms. Do I need to alter my diet? Pls suggest what needs to be done.
