Even after several years of study, the real cause behind the haemorrhoid disease is unknown. The common etiology behind the disease is associated with straining and irregular bowel movements. Mostly people who suffer from hard, bulky stools are the common patients for haemorrhoid because the hard stools push the cushions out of the anal canal. This leads to congestion and hypertrophy of the anal cushions, making the patients more prone to edema and bleeding.
Haemorrhoidectomy is a process of stapling back the haemorrhoid back in its place. Mostly doctors prefer using a scope with a special probe to locate the haemorrhoidal arteries so that they have to remove fewer tissues. This is a simple procedure and comparatively the least painful method of treating Haemorrhoid.
