Mr Karlheinz Jehle and Mr William Woods give an evidence-based update on effective management of haemorrhoids
Haemorrhoids are enlargements of the normal vascular cushions, which are essential in maintaining anal continence, and help differentiate between gas, liquid and solids in the anal canal. Weakening of supporting connective tissue leads to descent of the vascular cushion causing venous engorgement.
It has been suggested that constipation, diarrhoea, straining at stool and pregnancy contribute to the development of symptomatic haemorrhoids, although there is little evidence to support these beliefs.
The bottom line
1Haemorrhoids are not painful (unless strangulated and prolapsed).
2 Anal pain is usually due to:
3Rectal bleeding in combination with anal symptoms 'protects' the patient from colorectal malignancy (Thompson, BMJ 2003).
