Complications of haemorrhoids

1-minute read

In most cases haemorrhoids are mild and do not cause any serious problems to develop.

Haemorrhoids are not associated with an increased risk of bowel cancer. But some of the symptoms are similar. Tell your doctor about any haemorrhoid symptoms, especially bleeding.

Sometimes complications can develop as a result of haemorrhoid surgery. These can include:

  • excessive bleeding
  • infection
  • faecal incontinence, where you lose voluntary control over your bowel movements – this is is rare, and can sometimes be corrected with another operation
  • anal fistula, which is a small channel that develops between the inside of the anus and the surface of the skin near the anus.  

Before undergoing surgery it’s important to discuss the potential risks and benefits with your surgeon.

A digital rectal examination (DRE) is an important element of a clinical examination, performed by a doctor or nurse. It is a direct examination of the rectum and nearby organs, including the anal canal, prostate and bladder. While it can be uncomfortable, a DRE is critical to identifying illnesses such as benign prostatic hyperplasia (BPH), prostatitis (infection of the prostate), haemorrhoids, anal fissures, prostate cancer and anal and rectal cancers.
