Hemorrhoids are a condition involving the veins around the anus or lower rectum that have become swollen and inflamed. Hemorrhoids can happen either inside the anus or under the skin around the anus, and can happen in either external or internal veins in this region. You can have both types of hemorrhoids at the same time.
Common in both men and women, people can get hemorrhoids from straining to have a bowel movement. Other factors that can lead to hemorrhoids are pregnancy, obesity, aging and chronic constipation or diarrhea. Fortunately, there are many effective treatment options available.
