What are hemorrhoids?
Hemorrhoids are swollen veins that become distended in the rectum or anus, presenting similarly to how varicose veins do in the legs. There are two hemorrhoid types: internal and external hemorrhoids. Internal hemorrhoids are located under the mucous membranes along the lower rectum. External hemorrhoids occur underneath the skin surrounding the anus.
Typically, external hemorrhoids cause the most discomfort, as they involve the external skin that becomes irritated. A blood clot can also form inside an external hemorrhoid, which can be particularly painful and unpleasant. The clot can also produce excess skin, which can become itchy.
Internal hemorrhoids are not as symptomatic, even if they start to bleed. With these hemorrhoids, you may notice blood when wiping with toilet paper or using the bathroom. You may also experience external itching. However, internal hemorrhoids can cause a host of other complications 1.
