My 8 yr old dd has been prescribed lactulose for her constipation and recurrent stomach pain. She is on the 6th week of lactulose and is cutting down to 5ml once daily this week and then 2.5ml daily next week. Doctor said if she is still having stomach pain he will send her for a scan. What sort of scan will that be? Will it be an ultrascan? Anyone's lo has recurrent stomach pain? He also said he could felt stool in her stomach. Can that cause the stomach pain? She is passing soft stool daily, does it take long to empty the all the stool in the stomach? Thanks for your help.
