I will stick to role of homeopathy in treating piles rather than explaining piles, its causes, symptoms,etc.
To put it plainly, Homeopathic medicines are very effective in management of piles and the symptoms associated with it such as pain, bleeding, itching, etc. Rather I would like to add the relief of symptoms is obtained with absolute gentleness and without invasion or surgery. Point to be remembered is that piles has high relapse rate following surgical treatment, since surgery does not target the root causes like genetic tendencies, habitual constipation, etc. Homeopathic medicines work at the root level and can modify these genetic tendencies thus reducing chances of relapse and recurrence of the condition significantly.
Based on our experience in treating piles, I may state that Grade 1 and 2 of internal piles treatment can be significantly helped with homeopathy. Grade 3 piles can find some relief of symptoms with homeopathy but may not be completely cured. Grade 4 piles can get symptomatic relief with medicines.
