\b[Treat symptomatic <haemorrhoids> by correcting disordered defaecation and choosing an intervention suited to their position and severity. The main provoking factors are straining, <constipation> and disturbed bowel habits; <pregnancy> is another important setting.]
Normal <anal cushions> contain vascular channels and supporting tissue and help seal the <anal canal>. <Haemorrhoidal disease> is symptomatic enlargement, bleeding or displacement of these cushions, not simply the presence of normal <veins>. Internal <haemorrhoids> originate above the <dentate line>; external <haemorrhoids> lie below it in sensitive <skin>. This explains why an uncomplicated internal lesion can bleed painlessly, while an acutely thrombosed external lesion can be very painful.<Management of Benign Anorectal Disorders by the American College of Gastroenterology (2021)>[“Hemorrhoids”, definitions: normal cushions, position relative to the dentate line and symptoms]{ref}
<Constipation> with hard stools and repeated straining increases pressure and shearing stress in the <anal canal>. Prolonged sitting on the toilet and frequent abnormal bowel movements can aggravate symptoms. During <pregnancy>, pelvic venous congestion and <constipation> may contribute. Historical explanations often emphasised “congestion” from sedentary habits, abdominal pressure or obstructed venous return. These contain plausible mechanical observations but do not establish every old dietary or constitutional theory. In particular, <portal hypertension> can produce <rectal varices>, which must not be equated with ordinary <haemorrhoids>.
An 1867 surgical answer should distinguish relief of irritation from destruction or removal of the troublesome tissue. Measures then used included regulation of the bowels, avoidance of straining, local cleansing and soothing or astringent applications, and reduction of a prolapsed internal mass where appropriate. Operative approaches included tying the base with a <ligature> so that the tissue sloughed, excision with control of <haemorrhage>, and destruction by a heated cautery or clamp-and-cautery apparatus. Historical chemical cauterisation belongs to the same destructive principle. These describe period practice; indiscriminate caustics, cutting without haemostasis and tissue strangulation below the <dentate line> are not a modern treatment scheme.<Review of The surgery of the rectum (1865 book)>[p. 369: the third lecture on haemorrhoids and prolapse describes the clamp method, confirming its use before this exam]{ref}
In current care, increased dietary <fibre>, adequate fluid and better toilet habits are first-line measures; medicines may provide temporary symptom relief. Persistent internal <haemorrhoids> can be treated by <rubber band ligation>, <sclerotherapy> or <infrared coagulation>. <Rubber band ligation> interrupts the blood supply of a small portion above the <dentate line> and produces healing that fixes the displaced tissue. Advanced prolapse, substantial external disease or failure of less invasive treatment may justify <haemorrhoidectomy>; the operation must preserve enough intervening tissue to avoid <anal stenosis>.<Management of Hemorrhoids by the American Society of Colon and Rectal Surgeons (2024)>[Recommendations 3, 5 and 7; dietary measures, office procedures and excisional surgery]{ref}
The usual internal severity grades describe prolapse: grade I does not prolapse; grade II returns spontaneously; grade III needs manual replacement; grade IV cannot be reduced. These grades help select treatment but do not measure every patient's burden.<Diagnosis and treatment of hemorrhoids by the American Gastroenterological Association (2026)>[Table 1, classification by prolapse]{ref} Selected acutely thrombosed external <haemorrhoids> benefit from early excision; others settle with conservative treatment. A blanket promise of a permanent “cure” is inappropriate because recurrent provoking conditions and recurrent symptoms remain possible.<Management of Hemorrhoids by the American Society of Colon and Rectal Surgeons (2024)>[Recommendations 5–7 and section on thrombosed external haemorrhoids]{ref}
Finally, <rectal bleeding> must be investigated on its own merits. Examination, including inspection and suitable assessment of the <anal canal>, determines whether <haemorrhoids> explain the symptoms; other causes include <colorectal cancer> and <inflammatory bowel disease>. Persistent bleeding must not simply be labelled “piles”.<Diagnosis and treatment of hemorrhoids by the American Gastroenterological Association (2026)>[Anorectal examination, anoscopy and assessment of rectal bleeding]{ref}
