Haemorrhoids can be separated into two types: Internal and External Haemorrhoids.
Internal haemorrhoids are a normal engorgement of the internal haemorrhoidal plexus (collection of blood vessels) just above the dentate line (about 1/3rd of the way from the anal opening). They can contribute to around 20% of continence.
External haemorrhoids are found more just near the anal opening from engorgement of vessels around this region.
Haemorrhoids can become enlarged and push down the anus when abnormal and this can cause itchiness around the anus, mucous discharge, bleeding, pain (more associated with external haemorrhoid) and/or feeling a lump protrude out when defecating. In mild cases most of the time, improving bowel habits and increasing fibre and water consumption can treat the problem, however, in other cases a procedure may be helpful for symptoms, consult your specialist to find out what is best in your situation. Dr Simon Ho offers haemorrhoid treatment including banding and excision when appropriate.
