What is the best cure for constipation?

Fiber: I would increase your water and fiber intake.

The cure: depends upon the cause, so if this is a chronic problem, I would suggest seeing your doc for an evaluation.

Fiber & water: Increase your intake of fiber foods or take a fiber laxative like Metamucil. Drink enough water every day so that your urine is mostly colorless.

Fiber fluid excersis: I always tell my patients to start with the simple things of getting enough fiber (25gm/day, ), fluid (50oz/day) and exercise if persist add miralax (polyethylene glycol). Depending a the situation further work up is at times needed.
