I'm very constipated. went to dr. and he told me to take laxatives. i took two maximum strength laxatives and still can't poop...what could be wrong?

Your diet: the problem is your diet, life long of junk food will not be treated by a couple of laxatives.you need a lot of hydration 8-10 bottle of water,and natural juices, you need to avoid sodas ,and energy drinks.you need to eat fruits and vegetables,and a lots of fibers.for now take four tablets of dulcolax, then mix half bottle of miralax (polyethylene glycol) in 64 oz of Gaterade ,and drink it,repeat it once if needed.
