Hemorrhoids are one of the most common condition to affect humans, having been mentioned many centuries ago. The first descriptions of problems associated with hemorrhoids are found in the Bible, and the occupation of proctology apparently was established then as well. If you have hemorrhoids, you are not alone. They are a common problem. In fact, hemorrhoidal tissues are a natural part of the body. Most of the time you do not notice them as they help during bowel movements. But if these tissues become swollen or inflamed, they can cause uncomfortable symptoms. There are two different types of hemorrhoids depending upon their location-internal and external. 1. Internal Hemorrhoids are located in the inner lining of the rectum and cannot be felt. They are usually painless and can also lead to bleeding. 2. External Hemorrhoids, however, can be painful and swollen, and are located on the skin around the anus, and can be felt easily. Causes: The exact causes of piles are not known, but they can be associated with increased pressure in the blood vessel, in and around your anus. Constipation is one of the most common and important cause for piles problem. It may occur because of lack of fiber intake in your food. Other causes of piles can be being overweight, pregnancy or having family history of piles. Ageing is also one of the piles causes. Kshar Sutra Therapy: By this technique, Kshar Sutra is placed right at the root of hemorrhoidal tissue and the whole hemorrhoid is ligated with Kshar Sutra. Blood supply to the existing hemorrhoid is cut off and hemorrhoid will shed off after some days. Kshar Sutra that is placed at the root of hemorrhoid will help to prevent the recurrence of the disease.
