I wanted to add a post to warn others who have little ones given this diagnosis to just beware,it may be more serious.
I have 11wk old twins who were born about the same weight, both about 7lb, both really good feeders and stayed identical weights until about 7 weeks old when they were both about 12lb.
Then one started vomiting. Just one feed a day at first, always the 11pm feed for whatever reason.When I say sick I mean SICK, projectile reaching a few feet away.
Mentioned it a few days later to GP and she completely dismissed it "babies are sick, I'm sure its nothing to worry about" I went away feeling happy if a little foolish for being overly protective.
Anyway vomitting gets worse and worse, a couple of times a day, 3-4 times a day until maybe one a day would stay down. I've now been to the doctor a couple of times again to be made to feel like I was wasting her time. The the docto was away, and I saw a locum who thought it may be pyloric stenosis so sent me immediately to the paed. assess. unit at the hospital. After keeping him there around 6 hours, when the amount of assessment involved having me feed him twice and watching him throw up twice, clearing the length of a hospital bed, they diagnosed reflux, sent him home with appropriate medicine and told me I'd recive an appointment in2 weeks for a checkup. 3 days later he was weighed at the clinic and he'd lost 11oz since the hospital saw him, just 3 days prior and wasnt keeping anything down, including the medicine. I phoned the hospital and they said the medicine would take 2 weeks to work and that I would need to go back to the GP if I wanted him to be seen again. Off to GP who reluctantly saw me at the end of surgery on the friday. Again told me he wasnt dehydrated so he'd be fine. She phoned the hosptal who said they wouldnt see him if he wasnt dehydrated but they would phone on the monday to see him. Went away in tears because no-one was taking me seriously. Health visitor camr monday and he'd lost anoth 5lbin a couple of days. Paed dept phoned and said they wouldnt see him till thurs. I begged them to see him sooner telling them about the weight loss but the refused. By this time little one is chucking up everything, I'm keepig him still for hours on end to try and make something stay down and he's really sleepy all the time and he hasnt smiled in a week when he was really smiley before, he hasnt pooed in 2 weeks . See the doctor the next day who says he'd not dehydrated and maybe I'm overfeeding him (I'm just trying to keep 3oz down him). She suggests 1oz overy 3 hours(!!!) and says ther's still no need for the hosptal to see himsooner than thursday.
Health vistor weighs him the next day and another 6oz down. Phone the doctor who again says he's just got reflux. He now wont eat at all, and is very very sleepy all the time.
Consultant sees him the next day, listens to symptons, looks at his tummy while feeding, and diagnoses pyloric stenosis and svere dehydration. He's rushed up to the high dependency unit covered in drips, tubes and monitors and drips for 5 days until he is stable enough to operate. Thank god he's now recovering, albeit very thin and weak, and pretty sore around the scar but he'll be ok.
I know I've gone on a bit but I really wanted to implore anyone out there with these symptoms or the same non-interest to put your foot down and not accept the reflux thing if your gut tells you its more serious. We very nearly lost our little boy because of this, a couple more days and he wouldnt be here From now on, I'll be one of those people who abuses the A&E facility as I've lost faith in the GP/referral system.
