For hard, bulky stools, an osmotic laxative like Polyethylene Glycol (Miralax) is highly effective as it draws water into the colon to soften the stool, making it easier to pass. Alternatively, a stool softener like Docusate Sodium can help. Please drink plenty of water daily, as these medications require adequate hydration to work safely. You should also gradually increase your dietary fibre. Avoid stimulant laxatives (like Senna) for long-term use. If your symptoms persist for more than a week or if you experience severe abdominal pain, bleeding, or vomiting, please consult a doctor immediately.
