Piles (haemorrhoids) occur when veins around the anus and rectum become swollen due to increased pressure. Main causes include:
- Straining during bowel movements (often from constipation)
- Chronic constipation or diarrhea
- A low-fibre diet leading to hard stools
- Prolonged sitting or standing
- Pregnancy (pressure from the uterus + hormonal changes)
- Obesity
- Heavy lifting
- Aging (weakening of vein support tissue)
- Genetics/family history
In short, anything that increases pressure on the rectal veins over time can lead to piles.
