Blood in Your Stool: Don't Ignore This Warning Sign

Finding blood in your stool is alarming — but it is also one of the most important warning signs that should not be dismissed as simply "piles."

What does blood in stool mean? Blood in the stool can appear as bright red blood (suggesting a lower source, such as haemorrhoids or rectum), or dark, tarry stools (suggesting bleeding higher up in the gut, such as the stomach or small intestine).

Common causes:

• Haemorrhoids (piles) — the most common
• Anal fissures
• Diverticular disease
• Colorectal polyps
• Colorectal cancer
• Inflammatory bowel disease

When is it serious? You should seek urgent evaluation if:

• Blood is mixed in the stool (not just coating)
• You also have unexplained weight loss
• Your bowel habits have changed for more than 3–4 weeks
• You are over 40 years old
• There is a family history of colorectal cancer

A critical note for Pakistan: In Pakistan, rectal bleeding is commonly dismissed as haemorrhoids without further investigation. This leads to delayed diagnosis of colorectal cancer, which is increasingly common. Always get a proper examination, including a rectal examination by a doctor.

Key message: Blood in the stool is not always cancer, but it always deserves investigation. Please see a doctor — don't assume it's just piles.
