Is This Why You're So, Um, Backed Up?

Why it's causing a backup: Certain meds are known to stop people up. Three of the biggest culprits: tricyclic antidepressants, beta-blockers for blood pressure that have a diuretic effect, and any kind of narcotic or opioid (research in Pain found that 41 percent of people taking opioids for up to 8 weeks experienced constipation).

How to fix it: Ask your doctor about alternative medications that treat your underlying condition but don't cause constipation.
