Desperate for any ideas/advice. 5yo DS vomits pretty frequently. It started just over a year ago, before that he'd only ever been sick a couple of times properly since a baby. Last December he vomited once every couple of days for 5 weeks. GP did bloods, urine, stool sample - all fine. Eased off over summer/autumn but has increased again this winter and in the last 2 weeks he's been sick 4 times.
Saw a paediatrician in September for poor weight gain, who tested for lots of different allergies, coeliac, and did faecal calprotectin test - all came back fine and saw dietitian who recommended some dietary changes to boost protein and calories. Seems to have worked and he's gaining weight. But still the vomiting continues. GP has previously mentioned Cyclical Vomiting Syndrome but then why would it ease off in summer/autumn then come back? Last year in the worst patch it used to keep happening at 4am every time but now the times are random. Do other children randomly vomit this frequently?! Do we just accept it?! It just seems so much more frequent than friends' kids. I could take him back to the GP but I'm not sure what there is left to explore. Possibly reflux?! Any ideas??
