How can i identify a hiatal hernia in 14yr? we are unable to go to doctor for quiete a while and he complains of upper stomach pain sore throat

Enfoscopy: The only way to identify a hiatal hernia is an upper endoscopy which is performed by a gastroenterologist or a surgeon. He can also have an upper GI contrast study which will show larger hiatal hernias.

Difficult: It would be difficult to make this diagnosis without seeing a doctor. Usually an upper GI barium study could show this as well as an upper endoscopy. You could try some over the counter omeprazole(prilosec) to see if this alleviated the symptoms. Which would give you a presumptive diagnosis of reflux. But ultimately you should see a physician as these symptoms could be caused by other diseases.

Unlikely if ever: I can't recall EVER having a 14 yo with this in 4 decades of practice. They get simple gastroesophageal reflux, which is aggravated by their diet & other habits. A short course of OTC Prilosec (2-4 wks) and avoiding sodas, caffeine or reclining after meals resolves the symptoms in most.
