Haemorrhoids

Haemorrhoids are swollen, cushion-like blood vessels located in and around the lining of the back passage that become enlarged when subjected to increased pressure over time. This pressure commonly builds through straining during bowel movements, chronic constipation or diarrhoea, pregnancy, or simply the natural weakening of supporting tissue that comes with age. Haemorrhoids are extremely common, affecting a large proportion of adults at some point in their lives, and can occur internally, externally, or as a combination of both. Symptoms range from mild itching and irritation to noticeable bleeding or a palpable lump, and while haemorrhoids themselves are rarely dangerous, any bleeding from the back passage should always be properly assessed, since similar symptoms can occasionally be caused by other bowel conditions that need to be ruled out. Fortunately, most cases respond well to straightforward lifestyle changes or minimally invasive treatment.
