No, I don't think that is a common experience as far as a symptom of NK. But for heartburn, that is very possible if you have bumped up your fat intake and/or your protein intake.
It could be from too little stomach acid too. If your meal sits like a big lump that is usually a good sign of low stomach acid.
If that is the case you can check it easily by quaffing some apple cider vinegar diluted in water. :sick: yuk but if you feel better after doing that then it was for sure low stomach acid.
