Clinical photograph of a thrombosed external haemorrhoid (or pile). Haemorrhoids are enlarged (varicose) veins around the anus,which arise as a consequence of constipation (or on occasions,diarrhoea). In piles that do not protrude from the anus (first-degree haemorrhoids),bleeding following defaecation may be the only symptom. Some that protrude beyond the anus may resolve spontaneously; third-degree piles persist & need to be physically replaced through forceful dilation of the anus or surgery. Radical treatment is required if they become strangulated,which is accompanied by increased pain & enlargement | |
