Hey peepz, I've been struggling with GERD and additional symptoms like coughing up phlegm, asthma, digestive issues. I've had bloodtests in the hospital and a colonoscopy (not endoscopy). They only found a lactose intolerance (i dont eat lactose now), but no other allergies. Still I struggle to understand where my symptoms come from. Can food intolerances cause acid reflux? Because I mostly get these symptoms after I eat. Like a week ago I didn't have breakfast (not on purpose, was in a hurry) and went about my day and I realised I felt way better.
