There is no definitive answer to this question as it depends on the individual. Some people may find that cycling does give them piles, while others may not experience any issues. It is thought that the pressure that cycling puts on the perineal area (between the anus and scrotum/vagina) can contribute to the development of piles. This is because this area is rich in blood vessels and can be easily damaged. If you are susceptible to piles, then you may find that cycling makes them worse. However, this is not the case for everyone and some people may find that cycling actually helps to relieve their symptoms. If you are concerned that cycling is causing or exacerbating your piles, then it is important to speak to a medical professional.
