After ct scan, doc said im constipated. ordered me to take miralax (polyethylene glycol) for 5 days, but stopped after 3 from getting diarrhea. help! still feel constipated?

Let's define problem: Doctors define constipation as stools less frequently than once every 3-4 days. Patients feel they are "constipated" when passing hard or small volume stool, or they feel full ; bloated. We know from your x-ray you're not blocked. We don't know if your gut is sluggish or your rectum works correctly--these can be tested for (sitz marker study ; anal manometry, respectively). See a GI specialist.
