Haemorrhoids are a very common finding in the Western world and are often seen in our surgeries. They are frequently under-reported so their exact incidence can be difficult to quantify; however, estimates are that 50% of the population experience them by the age of 50. Because many people attribute symptoms of more serious pathology to haemorrhoids, careful evaluation is always very important. Fortunately, most cases are simple to treat and often resolve very quickly, although up to 10% of sufferers may require surgery to fully alleviate their symptoms. In this episode, Dr Roger Henderson looks at the classification of haemorrhoids, their predisposing factors, symptoms — including red flag symptoms — and treatments.
