I underwent an angioplasty in December and am currently taking prescribed heart medications. Since the last two months, I have been suffering from severe constipation and have to strain to pass stool. Could my current medications be causing this, and what safe medicines or laxatives can I take for relief?

Yes, certain heart medications such as calcium channel blockers, beta-blockers, or diuretics can cause constipation. Because straining can put unnecessary stress on your heart, it is important to address this. For heart patients, osmotic laxatives like polyethylene glycol or lactulose, and bulk-forming laxatives like psyllium, are generally considered safe. However, you should consult your cardiologist or doctor before starting any new laxative to ensure there are no drug interactions. They can also review your current prescriptions to see if an adjustment is needed. Meanwhile, try to increase your daily water intake and dietary fiber gradually.
