Hi Doctor, I have been facing frequent gastric issues and it usually lasts for 1-2 days. I feel bloated and release smelly gases excessively. I have been observing what I eat and realized it happens usually after I consume roti, but same is  not the case with parantha. Parantha is just fine, but after consuming roti, i see effect in 2-3 hrs. Not sure if this is some kind of food allergy or something else. Kindly advice a way forward. Thank you!
