why does heroin cause constipation? ive had it pretty bad after my use became very high.
Constipation is the most constant side-effect of any opiate/opioid. The best thing for it is, in my experience, to use Miralax (polyethylene glycol) once a day. This always kept my bowels regular... There's not much else you can do for the constipation because it's just going to happen, for the reasons stated above.
^Yeah there are opioid receptors in your intestinal walls that, when bound to by diacetylmorphine, decrease their wave-like movements (peristalsis) that is essentially the "motor" that drives your bowels to produce and excrete feces. Decreasing the speed of these proverbial gears disrupts the greater machine; constipation was always one of the most pronounced side effects of opiates for me when I was addicted to them... I have heard speculation that long-term heroin/other opioid use can increase the risk of colon cancer because waste product remains trapped in the body for long periods of time, but I cannot confirm that this is so.
Psyllium husk fiber powder will help produce bowel movements.

I believe that it is its effect upon acetylcholine receptors of the autonomic nervous system that causes decreased peristalsis.
Fiber will bulk the stool but has no effect upon motility.
