Haemorrhoids, or piles, are enlarged blood vessels that are found in or around the rectum and anus, according to the NHS.
Piles symptoms include bleeding after passing a stool, having an itchy anus, or finding lumps hanging down outside of the anus.
You can lower your risk of haemorrhoids by eating more fibre, losing weight, and not delaying going to the toilet if you need to pass a stool.
Drinking at least six glasses of water everyday may also prevent piles.
“The best way to prevent haemorrhoids is to keep your stools soft, so they pass easily,” said the Mayo Clinic.
“Drink six to eight glasses of water and other liquids [not alcohol] each day to help keep stools soft.”
Eating more fruit, vegetables and whole grains could also lower your risk of piles.
“Add fibre to your diet slowly to avoid problems with gas,” the Mayo Clinic added.
Straining, and holding your breath, while trying to pass a stool can lead to haemorrhoids.
It creates greater pressure in the lower rectum’s veins.
You should also go to the toilet as soon as you feel the need to pass a stool.
“If you wait to pass a bowel movement and the urge goes away, your stool could become dry and be harder to pass,” the clinic said.
The exact cause of haemorrhoids isn’t clear, according to the NHS.
But, they’ve linked to increased pressure in blood vessels in and around the anus.
The pressure causes blood vessels to become swollen and inflamed.
About half the people in the UK develop one or more haemorrhoids at some point in their life.
