Welcome to the gastroenterology community! There is no problem with taking a mild laxative like miralax for that period of time (which is actually a very short period of time). However, it is not normal to get x-rays to look for constipation. Usually you should just go off of frequency of bowel movements, consistency of bowel movements, and whether or not she is having pain, difficulty having bowel movements, bloating, etc. Was she having any problems before she got the flu? I think she is not getting the proper care and needs to be seen by a gastroenterologist.
Thanks for a reply which indicates we are not off track.
She was perfectly fine before having the flu. She used to occasionally complain of tummy ache. But that has been the feeling she used to have since early years when she was very hungry.
The problem here is that she was going to pre-school earlier. We took her off the pre-school since all this started. Her kindergarten starts in few months. Not sure how will she manage it.
Frequency - 6-7 times in a day. It is not very formed but not completely watery. She does not complain of pain but keeps complaining that i just went 5 mins ago and i feel like going again.
We are following the gastroenterologist's recommendation till now. Just not sure if we are trying to treat the right problem or not.
Usually a doctor would recommend trying dietary changes to help with constipation before putting them on a daily laxative. I think she needs to back down on the amount of laxatives. I think the doctors have you overtreating her problem. I think she needs a second opinion with another gastroenterologist. Sorry I couldn't be of more help.
