Causes and self-care
Low fiber, not enough fluids, inactivity, and ignoring the urge are common culprits; iron pills, opioids, some blood pressure meds, hypothyroidism, and pregnancy can also cause it. Gradually work up to 25–34 grams of fiber a day from fruits, vegetables, and whole grains, and drink plenty of water. Try sitting on the toilet after breakfast, when the gastrocolic reflex kicks in, with a footstool to raise your knees.
Choosing a laxative and red flags
Psyllium (bulk-forming) and osmotic agents like polyethylene glycol (MiraLAX) or magnesium are first-line and generally safe. Stimulants like senna or bisacodyl work well for short-term use. New constipation after 45–50, blood in stool, weight loss, anemia, or a family history of colon cancer warrants a colonoscopy. Chronic straining can lead to hemorrhoids.
