Haemorrhoids are part of your normal anus. The role of haemorrhoids is to work like cushions to close the anus airtight.
That way, when you cough or sneeze, you don't leak gas or stools. However, haemorrhoids can swell and cause problems such as bleeding or prolapse when you pass stools. Treatment of haemorrhoids depends on what problems you face.
Bleeding haemorrhoids can be treated by medication, stool softeners and change of toilet habit. A prolapsed haemorrhoid can be ligated with a rubber band if it is not large.
Large haemorrhoids may require surgery. Choice of surgery depends on the size and type of haemorrhoid as well. You should speak to a surgeon specializing in colorectal surgery to discuss your options.
