Haemorrhoids, also known as piles, are swollen veins found inside or around the anus and lower rectum. They can cause discomfort, itching, pain, and bleeding during bowel movements. Haemorrhoids are very common and can affect people of any age, though they are more frequent in adults.
Haemorrhoids develop when pressure increases in the veins around your anus, often due to straining during bowel movements, constipation, or sitting for long periods. Pregnancy, obesity, and a low-fibre diet can also make them more likely. Over time, this pressure causes the veins to swell and become irritated.
The common symptoms include itching, soreness, and swelling around the anus, as well as bright red bleeding after passing stools. You might also feel small lumps near your anus, or experience pain when sitting or going to the toilet. Internal haemorrhoids are usually painless, while external ones can be more uncomfortable.
