Diet Restriction to Reduce Bedwetting

Cochrane reviewed two trials on dietary restriction to decrease bedwetting. A low antigen diet restricts diary, gluten, eggs, and most meats.  A small trial showed an improvement with dietary restriction but a relapse occurred in 6/9 children given test foods compared with 0/9 given placebo  foods. The second trial of dietary restriction only had one patient at the end of the trial dry with a high drop out rate.
 
My thoughts: Chances are you are already having hydrating and voiding “power struggles” with your child.  I would avoid adding another conflict when there is poor evidence to support it. (Sample size was too small.)  This is a very limited diet with a high drop out rate.
