7 year old with history of constipation

[Guest guest]

My friend's daughter has a history of constipation since she was few

months old. Her dr just has her use ExLax and Miralax every so often

to " clean her out. " Is it normal for 7 yr old to continue to have to

be cleaned out? She eats fruits/vegs and has plenty of exercise,

limits dairy and no grains. Almost every night she complains of her

stomach hurting and thinks she needs to throw up but never does. This

doesn't seem normal to me for a child to have to feel this way.

Any advice would be appreciated.
