Hemroids occur naturally in and around the anus and lower rectum. Increased pressure and swelling may result from straining to make a bowel movement. The blood vessels stretch under pressure, similar to varicose veins in the legs. Pregnancy, heredity, aging, anal intercourse and chronic constipation or diarrhea are other factors that may cause hemroids.
Swollen veins under the skin around the anus are considered external hemorrhoids, while swollen veins inside the anus are considered internal hemorrhoids. There are also additional complications that can cause an aggravated case of hemroids. Thrombosed and strangulated hemroids are examples of these.

Many anorectal problems, including fissures, fistulae, abscesses, or irritation and itching (pruritus ani), have similar symptoms and many times are, incorrectly, referred to as hemroids. To get a definite diagnosis, you should consult your doctor.
Hemroids usually are not dangerous or life threatening. Usually hemroid symptoms will go away on there own after a few days.
Although many people have hemroids, not all experience symptoms. Bright red blood covering the stool, on toilet paper, or in the toilet bowl is the most common symptom of internal hemroids. However, an internal hemroid may protrude through the anus outside the body, becoming irritated and painful. This is called a protruding hemroid.
Symptoms of external hemroids may include painful swelling or a hard lump around the anus that results when a blood clot forms. This condition is known as a thrombosed external hemroid.
In addition, excessive straining, rubbing, or cleaning around the anus may cause irritation with bleeding and/or itching, which may produce a vicious cycle of symptoms. Draining mucus may also cause itching.Sitz Baths are one method may help relieve hemroid symptoms.
