Passing hard stools with blood is often due to haemorrhoids or a small tear (anal fissure) caused by straining. However, any rectal bleeding must be evaluated by a healthcare professional to rule out more serious conditions. Please avoid self-medicating without a proper diagnosis. To help soften your stool naturally, increase your daily water intake and eat more fibre-rich foods. You may use a mild, over-the-counter stool softener (like docusate sodium) after consulting a pharmacist. Seek immediate medical attention if you experience heavy bleeding, black or tarry stools, severe abdominal pain, dizziness, or lightheadedness.
