Hemorrhoids are swollen veins located around the anus or in the lower rectum.
Based on the locations, the most common types are as following:
- Internal hemorrhoids develop within the anus or rectum.
- External hemorrhoids develop outside of the anus. They are the most common and most troublesome.
- Mixed hemorrhoids incorporate both internal and external components.
Though the condition can be very painful, they won't cause death. Also, they often go away on their own without treatment. Even the serious ones are treatable.
But you need to receive immediate treatment if you have large amounts of rectal bleeding, lightheadedness and faintness.
