What they are: Swollen and inflamed blood vessels underneath the surface of the anal canal.
How they arise: Increased pressure—often from straining during bowel movements, chronic constipation or diarrhoea, pregnancy, or sitting for long periods—causes these veins to engorge and stretch the lining of the anal canal.
Symptoms: Bright red rectal bleeding, anal itching, discomfort, or a palpable lump at the anus.
Treatment options:
Non-operative: Avoid surgery with bespoke lifestyle advice
Minimally invasive clinic procedures: injection sclerotherapy, rubber band ligation
Surgery: open haemorrhoidectomy, ligasure haemorrhoidectomy, HAL-RAR (haemorrhoidal artery ligation and recto-anal repair)
What they are: Small tears in the lining of the anal canal.
How they arise: A tear due to the passage of hard stool, leading to a vicious circle; severe anal pain causing spasm of the anal sphincter, leading to poor blood supply, which stops healing, resulting in ongoing pain and further spasm, etc.
Symptoms: Sharp pain during and after bowel movements, bleeding, and sometimes a small skin tag (“sentinel pile”) at the fissure site.
Treatment options:
Medical
Botox® injections
What they are: Small, benign flaps of excess skin that protrude from the anal margin.
How they arise: As swelling from haemorrhoids recedes, the overlying skin can remain stretched and form a tag.
Symptoms:
o Usually asymptomatic and discovered incidentally.
o May cause hygiene challenges, trapping of stool or debris.
o Can lead to itching, mild discomfort, or a sensation of fullness at the anus.
