Q

Treatment of constipation in childhood

A

the main thing is - de-impaction regime for the child with Movicol
dont want to increase peristalsis in case of obstruction

If not impacted –//always first line -DIET
increase fibre intake, increase water intake,
Reward diaries in case of painful movements -encourage child to go to bathroom

impacted–
1st line - osmotic laxative -eg lactulose/movicol
2nd line -stool softners -docusate sodium suppositories
those 2 esp good with witholding behavours -

want to do this for about 2 weeks with a few sachets
then move to maintenance dose

very very persistant -specialist and possible surgery
