Whoa. I have been struggling with this issue for a long time. My gut has turned very sensitive and bloated. I could have a hard day even if I have strong coffee. Let alone skip a meal. My medical diagnosis doesn't show any problem with my stomach or gut. I used to smoke and there used to be times when it was stressful at work and I believed it was natural for anyone these days. After 2 years of stoppinh smoking + taking care of my diet + medicines it is still not gone completely. It's uncomfortable to live with this.
