[|Human|] My 24 year old son was diagnosed with strep throat saturday and started antibiotics.  By Tuesday his stomach hurt so bad he went to ER....They said after an ultra sound that his gallbladder was swolen.   On the IV with antibiotics he felt bettter, now 12 hours later his stomach is bad again, he thinks its the antibiotics.  Im wondering if it is just anything he puts down his stomach affects his gallbladder????? Help I dont want another trip to er
[|AI|]  Hello! Thank you for the query. Antibiotics quite often cause some gastrointestinal issues. Like every medicine they can irritate stomach causing stomach ache. Usually it is nothing serious, however if it starts recurring, some diagnostics is necessary. Swollen gallbladder should rather get better after antibiotics. So it is hardly possible that antibiotic itself has caused such issue. More possible is that your son has peptic ulcer which get irritated by antibiotic. In case of peptic ulcer, ultrasound is usually useless. I suggest your son to visit a doctor once again. CRP, and blood work should be done along with an ultrasound. If nothing will be found, gastrostomy should be next. Hope this will help. Regards.
