Piles or hemorrhoids are basically lumped within the rectum or around the anus that contains swollen and engorged blood vessels. This condition may usually exist without symptoms but in some cases, there could also be bleeding with passage of stool and bleeding. Types of piles Piles could also be of two classic types: Internal hemorrhoids are present just inside the anus, at the start of the rectum. There’s a line of demarcation between the rectum and anal canal called the dentate line. Internal hemorrhoids lie above the dentate line. These are commonly painless and sometimes tend to bleed. External hemorrhoids that are present at the anal opening often hanging outside the anus. These lie below the dentate line. These could also be painful. Pressure on blood vessels The explanation for hemorrhoids or piles is typically excess pressure on blood vessels in and around the anus. This might occur in individuals with future constipation. Once they strain to pass the stools there’s increased pressure on the blood vessels within the rectum and anal canal that results in their swelling and inflammation.
