Thank you for your query.
can cause both stomach ache, cramps and lethargy
. Did Movicol help your daughter?
You should lay more stress
on your daughter's nutrition so that she has a high fibre diet which shall prevent her from getting constipated. You may like to have look at this site http://goo.gl/zRm1Q for more details on high fiber diet.
I hope I have answered your query to your satisfaction.
Wishing your daughter an early recovery.
