Haemorrhoids

Often described as “varicose veins of the anus and rectum”, haemorrhoids are enlarged, bulging blood vessels in and about the anus and lower rectum. There are two types of haemorrhoids: external and internal, which refer to their location.
External (outside) haemorrhoids develop near the anus and are covered by very sensitive skin. These are usually painless. However, if a blood clot (thrombosis) develops in an external haemorrhoid, it becomes a painful, hard lump. The external haemorrhoid may bleed if it ruptures.
Internal (inside) haemorrhoids develop within the anus beneath the lining. Painless bleeding and protrusion during bowel movements are the most common symptom. However, an internal haemorrhoid can cause severe pain if it is completely “prolapsed” – protrudes from the anal opening and cannot be pushed back inside.
