I'm 23 years old, height 6 feet. I'm having gastric problem I think. I regularly get pain below my chest when I take more food especially spicy items. Is this a gastric problem? I'm a very active & sports person since my childhood. Now i'm not involving in any activities from 3 years, only going through my studies. Even though i'm taking controlled diet my belly is very loose. I'm not having stiff body. What can I do for a good personality?
