Well first I will tell you that you need to visit a doctor ASAP or go to the ER, because not having a bowel movement in 5 days or even more can be extremely bad. By that I mean, if it stays backed up inside you for too long and your intestine burst that can be deadly. Poisons and toxins in the there could cause bad infections and that could be deadly. So you need to go to the doctor or ER, and this is serious, because laxatives aren't going to help and i'll tell you why.

Even if you are eating more than you were before a lack of food leads to small, inadequate stools that have a hard time (even if they're soft) moving through the colon. If you're not eating enough this will be frequent and common. Also you said that you used to have a laxative addiction? Well that could be causing it because the body becomes dependent on the laxatives to defecate, making it difficult for the body to naturally pass a stool once the laxatives are no longer being used.

What it seems you have now is :
Laxative dependence. This is when the colon requires larger and larger doses of laxatives to produce bowel movements. People often become so dependent on laxatives that their body loses the ability to produce bowel movements on it's own without the aid of laxatives.

I suggest you take NO MORE laxatives and go to the doctor to get this sorted. Speak to a nutritionist if you have one or get one..Not eating enough ends up causing more harm than good.

I agree with silence_, the frequent use of laxatives before could have upset your bowels and they got used to not moving because the laxatives just took over and there was no need for natural colon spasms that make you go.

The toxins thing is a myth, though. I've read medical info that says you won't get poisoned by the poop sitting in your body, but it IS very uncomfortable, and if it goes on for long enough, you may need an enema.

Definitely see your doctor or go to a walk-in clinic and tell them about this. They'll be able to help you out. :)

OH and milk backs you up, too. Try to just have water (room temperature water would be best).

Also, fiber like bran and wheat just make constipation worse IF you don't get enough water or liquids to flush them through the digestive system. So keep eating fruits, have water, and see a doctor.

Hope this helps!

same thing happened to me!! I don't know how to put it but...you are filled with shit haha you gotta go to the doctor, they will probably give you meds and tell you that you need some enemas lol

You need to go to the doctor. This could be serious problem.

you should definitely go to the doctor

you mentioned on another post that you were anorexic. I think that takes part in this and you should definitely go to the doctor.
