I would like to especially aware parents of developing countries that don’t ignore persistent nausea and vomiting of your infants, toddler and young kids. I feel parents are the main life saver to early identify symptoms and report to doctor. And being a parent, ask doctor for investigation. As in my case my daughter’s symptoms were totally ignore by health team since her birth, no investigation done and once her severity increases she ended up into a formation of unusual calcium oxalate stone. Wishing you a healthy lifestyle to all hyperoaxluria.
