Noticing blood in your stools can be unsettling and it may stem from a range of causes – from simple haemorrhoids to other digestive conditions.
Noticing blood in your stools can be unsettling and it may stem from a range of causes – from simple haemorrhoids to other digestive conditions. Understanding these possibilities can help you recognise when a medical assessment may be appropriate.
Should I Be Worried If I See Blood in My Stool?
Not always. In many cases, bright red blood during or after a bowel movement is caused by haemorrhoids (piles).
Haemorrhoids are swollen veins in or around the rectum and anus, similar to varicose veins in the legs. They can develop internally within the rectum or externally under the skin around the anus. External haemorrhoids can sometimes be tender or painful.
You should be more concerned if you notice:
- Persistent bleeding or larger amounts of blood
- Dark red or black stools, or blood mixed within the stool rather than from wiping (this may indicate stomach or colon issues)
- Unexplained weight loss, abdominal pain or changes in bowel habits
Why Do Piles Form?
Straining during bowel movements, often caused by constipation, is a common cause. Pregnant women are also prone to developing piles due to additional pressure in the pelvic area.
Sitting for long periods, particularly on the toilet, and obesity are additional risk factors. A low-fibre diet, which leads to harder stools, can further exacerbate the problem.
In short, any condition that puts prolonged pressure on the rectal veins can contribute to the formation of haemorrhoids.
What Does Haemorrhoid Bleeding Look Like?
Bleeding from piles is usually:
- Bright red, not dark or black
- Limited to the surface, often on toilet paper or dripping into the toilet after passing stool
- Painless in most cases, especially for internal haemorrhoids. Painful bleeding or clots are more common with external haemorrhoids.
Other common symptoms of piles include:
- Anal itching or irritation
- Discomfort while sitting
- Mucus discharge after a bowel movement
- A sensation of incomplete emptying after a bowel movement
How to Tell the Difference: Piles vs Stomach or Colon Cancer
It’s important to distinguish haemorrhoid bleeding from bleeding due to more serious conditions like colorectal or stomach cancer.
| Haemorrhoids | Digestive Cancer |
|---|---|
Blood colour: Bright red | Blood colour: Dark red or black |
Blood location: On the stool surface or toilet paper | Blood location: Mixed within the stool |
Pain: Usually mild or none (unless external haemorrhoid) | Pain: May have abdominal pain, unexplained weight loss, or changes in bowel habits |
Onset: Often related to straining | Onset: Gradual, persistent, may worsen over time |
Rule of thumb: Bright red blood after straining, without other concerning symptoms, is most commonly due to haemorrhoids.
However, persistent bleeding, dark or black stools, blood mixed within the stool, unexplained weight loss, or ongoing abdominal pain should prompt a medical evaluation, as these may indicate conditions affecting the stomach or colon.
At VEC specialist group, we can assess the cause of rectal bleeding, determine whether haemorrhoids or another condition is responsible and advise on appropriate treatment options.
If your symptoms persist or you would like further evaluation, visit our general surgery clinic for a timely review.
Other Causes of Bleeding Around the Anus
Not all bleeding in the anal region comes from the rectum itself. Pilonidal sinus (not inside the anus, but near the tailbone) can also cause bleeding or discharge that patients may mistake for rectal bleeding.
This happens when the sinus becomes infected or forms an abscess, leading to pain, swelling, and blood-stained discharge in the buttock crease.
If bleeding is coming from the skin near the tailbone rather than the anus itself, a pilonidal sinus may be the underlying cause.
