Although many people have hemorrhoids, not all experience symptoms. The most common symptom of internal hemorrhoids is bright red blood covering the stool, on toilet paper, or in the toilet bowl. However, an internal hemorrhoid may protrude through the anus outside the body, becoming irritated and painful. This is known as a protruding hemorrhoid.

Hemorrhoids are common. In the USA, the prevalence is about 4.4%. It is estimated that approximately one half of all Americans have had this condition by the age of 50, and that 50% to 85% of the world's population will be affected by hemorrhoids at some time in their life. However, only a small number seek medical treatment. Annually, only about 500,000 in the U.S. are medically treated for massive hemorrhage, with 10 to 20% of them requiring surgeries.

Unless there is rectal bleeding, most people with hemorrhoids can diagnose and treat the problem themselves. If you have rectal bleeding, it is important for you to see a physician, so he or she can check for more dangerous causes of bleeding.

Listed below are the most frequent causes of hemorrhoids:

Constant sitting

Straining with bowel movements (from constipation or hard stools)

Diarrhea

Sitting on the toilet for a long time

Severe coughing

Childbirth

Heavy Lifting

If the hemorrhoid originates at the top (rectal side) of the anal canal, it is referred to as an internal hemorrhoid. If it originates at the lower end of the anal canal near the anus, it is referred to as an external hemorrhoid. Technically, the differentiation between internal and external hemorrhoids is made on the basis of whether the hemorrhoid originates above or below the dentate line.

Measures to reduce symptoms include:

warm tub or sitz baths several times a day in plain, warm water for about 10 minutes

ice packs to help reduce swelling

application of petroleum jelly, cortisone creams, hemorrhoidal cream (such as Preparation-H) or suppositories to the affected area

wearing cotton underwear and loose clothing

cleaning the anus after each bowel movement by patting gently with moist toilet paper or moistened pads

taking acetaminophen or aspirin

Treatment may include warm baths and a cream or other medicine. If you have large hemorrhoids, you may need surgery and other treatments. There is no relationship between hemorrhoids and cancer. However, the symptoms of hemorrhoids, particularly bleeding, are similar to those of colorectal cancer and other diseases of the digestive system. Therefore, it is important that all symptom are investigated by a physician specially trained in treating diseases of the colon and rectum.
