Hello. My daughter is 4 months old. We had constipation and were sent for an ultrasound. The ultrasound showed a distorted appearance of the gallbladder, bile stasis. And we're being sent to a gastroenterologist. But there, they also wrote down hepatomegaly, reactive changes in the parenchyma of the liver, spleen. Our pediatrician didn't comment on this. I am afraid to read something online, there is nothing good written about it. Has anyone had such diagnoses? Who did they consult?
