### input:
my baby is 10 wks old...at one and a half wks he got very constipated and was screaming trying to poop. we added 1/2 tsp prune juice to every bottle for a wk and it started to help. but we had to keep that up and also he was spitting up and vomiting all the time and wheezing and arching his back feeding and very uncomfortable so we put him on prevacid and started switching formulas. after 4 or 5 diff ones he is actually worse now soaking 4 bibs a day and vomiting all day. it is projectile and it is often and it hurts his sometimes. we also have had to put milk of magnesia is every bottle for 6 wks now to help him poop. it helps but nothing is consistent or great . the gastro dr. put him on a laxative instead and uped the prevacid. nothing is working i am running out of ideas. should i try soy? he is 10 wks now and he is thriving greatly so they dont see any issues but he is misserable please help me!!!!!

### output:

Your baby may be suffering from digestive problems like gastroesophageal reflux, pyloric stenosis (narrowing of the opening between the stomach and intestines), food allergies, overfeeding, or improper position while feeding in infants, infections of gastrointestinal tract etc. Ask your doctor for investigations like USG abdomen, CBC, stool examination, urinalysis, CBC etc. These investigations can diagnose the exact cause. For vomiting give medications like ondansetron or risperidone. Put baby upright on shoulder for at least 10 to 15 min after every feeding. If possible breastfeed baby instead of formula. For further queries regarding this disease or its medications you may take my appointment at Chat Doctor.
