🚸 Blood in Stool : 9 Common Causes And When to Act Fast 🩺
Seeing blood in your stool can be frightening but it’s a warning sign, not a diagnosis. The colour tells us a lot: bright red usually means bleeding lower down (near the anus/rectum), while black, sticky, tar-like stool points to bleeding higher up in the stomach or small intestine. Here’s what may be behind it:
📋 9 Common Causes
1. Haemorrhoids, Swollen veins around the anus/rectum; bright red blood on toilet paper or stool, itching, discomfort. Very common with straining, pregnancy, or sitting too long.
2. A**l Fissure, Small tear in the a**l lining; sharp pain when passing stool + bright red blood, often linked to hard stools or constipation.
3. Diverticular Bleeding, Small pouches in the colon that can bleed; sudden, usually painless bright red or maroon blood.
4. Colorectal Polyps, Soft growths inside the bowel; can bleed painlessly. Some slowly turn into cancer over years, screening removes this risk!
5. Colorectal Cancer, Persistent or intermittent bleeding; often with changed bowel habits, unexplained weight loss, or tiredness from anaemia. Early stages can be silent, screening saves lives.
6. Inflammatory Bowel Disease (Crohn’s / Ulcerative Colitis) Inflamed bowel lining; bloody diarrhoea, cramping, urgency, fatigue, weight loss. Needs specialist care.
7. Infectious Colitis,c Bacterial/parasitic infection; bloody diarrhoea, fever, cramps, vomiting, watch closely for dehydration.
8. Peptic Ulcer / Upper GI Bleed, Stomach or duodenal bleeding causes black, tarry stool; sometimes vomiting blood or "coffee-ground" material. Linked to H. pylori or overusing NSAID painkillers.
9. Angiodysplasia, Fragile, abnormal blood vessels in the bowel wall; painless, intermittent bleeding, more common as we age, can cause anaemia over time.
🚨 Get URGENT Help Right Away If:
- Heavy, continuous bleeding or blood clots
- Black, tarry stool or vomiting blood/coffee-ground fluid
- Severe abdominal pain, dizziness, fainting, rapid heartbeat, extreme weakness
- Blood + unexplained weight loss, persistent bowel change, or pale tiredness
❤️ My Sincere Advice:
✅ Never ignore blood in stool or brush it off as "just piles." Even if you have haemorrhoids, new or different bleeding always needs checking, don’t self-diagnose!
✅ Know your NSAID limits. Ibuprofen, aspirin, naproxen can damage the stomach lining and cause ulcers/bleeding, never take daily long-term without medical advice.
✅ Don’t fear the test. Colonoscopy can find and remove polyps before they ever turn into cancer, the single best protection against bowel cancer.
✅ Hydrate + soften stools. Drinking enough water and eating fibre reduces straining, which helps haemorrhoids and fissures heal and prevents new ones.
✅ Watch for anaemia. Ongoing small blood loss quietly drains iron, constant tiredness, pale skin, shortness of breath? Get bloods checked too.
✅ Tell the full story. When you see your doctor, describe the colour, amount, pain, and bowel habits, that detail speeds up the right diagnosis.
