M.K.
it could be. I would visit reflux.org it's all about reflux/gerd in adolescents and has some good tips and questions for doctors. my daughter still has reflux issues at 8 years old, but they are very controllable with medication and diet modification. You can try gripe water and you can add twice the normal dose of mylicon or gas drops to every bottle (they can't OD on it) and see if that helps. she got worse with teething and with gassy foods and peaches. you can send me a personal message if you like.
