Ayurvedic Treatment for Piles & Fistula
Haemorrhoids are abnormally enlarged vascular mucosal cushions in the anal canal. These mucosal cushions are 'normal findings' - they help to maintain anal continence. It is only when they become enlarged and start to cause symptoms that they become haemorrhoids.
Haemorrhoids originate either above the dentate line (internal haemorrhoids) or below the dentate line (external haemorrhoids). The dentate line is 2 cm above the anal verge and is the anatomical delineation between the upper and lower anal canal.
Are classified according to the degree of prolapse, although this may not always reflect the severity of symptoms.
• First-degree haemorrhoids (grade I): do not prolapse.
• Second-degree haemorrhoids (grade II): prolapse on straining; reduce spontaneously.
• Third-degree haemorrhoids (grade III): prolapse on straining; can be reduced manually.
• Fourth-degree haemorrhoids (grade IV): permanently prolapsed; cannot be reduced.
They are painless unless they become strangulated.
• Lie under the perianal skin just inside and outside the anal verge below the dentate line.
• Are covered by squamous epithelium and have sensory innervation so may become painful and itchy.
• May be visible on external examination.
