I assume Emma has GORD, gastro-oesophageal reflux disease which is a type of acid reflux which can interestingly cause oesophagitis which is what Phizzle says Emma now has. GORD is treated by changing diet, quitting smoking and medication.
Not to mention losing weight and not eating fatty or spicy foods, no caffeine and no alcohol.
