The short explanation
Bright red blood after passing stool, without pain, is most often caused by piles, which are swollen blood vessels in the back passage. At your age, serious causes are much less common. Still, any bleeding from the bottom is worth getting checked rather than assuming, because only an examination can confirm where it is coming from. A doctor will ask about your bowel habits and may gently examine the back passage, sometimes using a short scope. If the cause is piles, treatment often starts with softer stools, avoiding straining and sometimes a cream or simple procedure. If anything does not fit, further tests can be arranged.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Blood mixed into the stool, dark red or black blood, mucus, a change in bowel habit, weight loss, tiredness or a family history of bowel cancer make further tests more important.
- Constipation and straining are common triggers for piles.
- Embarrassment stops many people from getting checked; doctors see this every day and you can ask for a woman doctor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you where the blood is coming from. An examination is needed to know the cause.
