A few months ago my stomach suddenly changed over about a week. Everything I eat other than meat causes me problems. EVERYTHING. Not every single meal, somedays are better than others. I use to eat a bowl of cereal a day with whole milk, now I cant touch milk. Im an athlete and when I drink gatoraid and eat a granola bar, I will be burping for the next three hours. When I eat lunch or dinner, it feels like a brick on top of my stomach for then next three hours.
Ive tried like five different probiotics with no relief. I feel like something killed my gut bacteria but Im failing to fix it. Suggest a solution, if you think I need a probiotic, suggest one that really works.
