Hemorrhoids are cluster of veins, which develop under the skin of anus. Hemorrhoids or piles extend from inside the anus (internal hemorrhoids) to outside the anus (external hemorrhoids). They are caused by increased pressure on related veins. Pregnancy, long sittings on toilet, long term constipation, long term diarrhoea, liver diseases etc cause them to enlarge.
Everyone has hemorrhoids, but not everyone is bothered by them. Minimally invasive techniques are good option for treating internal hemorrhoids, since that area has nerve ending for pressure but not for pain. Navkar Surgical Hospital have top surgeon for piles surgery.
Unfortunately, external hemorrhoids cannot be treated with “painless” techniques because the skin over them is very sensitive.
