Why does colon cleanser work for constipation and then its comes back???

Underlying cause: This is because your are not treating the underlying cause of your constipation. Try increasing your fiber and water intake, you can try adding Miralax (polyethylene glycol) every morning as an alternative if you can't increase your fiber intake enough. If you are using any opiate medications this can contribute ro recurrent constipation. See your doc if fiber and trying over the counter stool softeners isn't working.
