Why Am I Constipated? Common Causes, Contributors & Red Flags
Constipation is a symptom, not one single disease. It can reflect diet and routine, medications, pelvic-floor problems, medical conditions or other causes, which is why persistent constipation should not automatically be treated as a supplement deficiency.

Diet and routine
Low fiber intake, inadequate liquids in some contexts, low activity and disruption of normal bowel routines can contribute. Travel and schedule changes are common examples.
Medications and supplements
Many medicines can affect bowel habits. Opioids are a well-known example, but the list is broader. If constipation starts after a new medicine or dose change, ask a pharmacist or clinician rather than stopping a prescription on your own.
Health conditions
Constipation can accompany metabolic, neurologic, structural and pelvic-floor disorders. That is one reason chronic symptoms deserve evaluation instead of repeated self-treatment.
