An 11-year-old boy presented to the general physician with complaints of non-projectile, nonbilious vomiting of food particles,, and epigastric pain for 15 days. The child brought up almost 1 liter of food particles and swallowed it again repetitively 3-4 times a day. The child also lost a significant 6 kg of weight in one month . He was able to recognize the food he swallows again.
This process tends to cease when the re-swallowed material becomes acidic to taste. Based on the signs and symptoms, which is the most suitable diagnosis in this child? (The answer is posted in the comment section below!)
