Hemorrhoids are inflamed and swollen veins in the anus and lower rectum which is the end of the large intestine leading to anus. Hemorrhoids can be categorized into two types with reference to their location:
External hemorrhoids usually developed under the skin around the anus and forms a blood clot under the skin. It usually forms a hard lump around the anus that can be very painful and sensitive to touch and may bleed on rupture.
Internal hemorrhoids are small and develop in the walls of the anal canal. The hemorrhoids can be very painful if the bulging hemorrhoid are squeezed by the anal muscles. Painless bleeding and mucus during bowel movement are common symptoms of internal hemorrhoid.
Causes of hemorrhoids
Though the exacts causes of hemorrhoids are unknown, however physicians have a few theories on how hemorrhoids might be caused. Applying too much pressure on the veins in the pelvic and rectal area causes hemorrhoids. Tissues inside the anus fills with blood during bowel movement , by straining to move the bowel the pressure on the veins increases which results in swelling and stretching of the tissue causing hemorrhoid. Diarrhea or constipation are the most common causes of hemorrhoid. Pregnant women suffer from hemorrhoid in their last six to seven months of pregnancy. This is due to the increased pressure on the blood vessel in the pelvic area which is caused when straining to push the baby out.
Hemorrhoid are common in both men and women. The most common cause of hemorrhoid is aging. More than forty percentage of men and women have hemorrhoid by the age of fifty to sixty five.
Symptoms of hemorrhoid
Common of symptoms are:
- Passing of blood and mucus in the stool
- Hard sensitive lumps around the anus
- Blood clots around the anus
- Bulged veins inside the rectum.
- Irritation or itching in the anal area due to draining mucus.
Though hemorrhoid is not life threatening and may go away within few days. Not all patients show the same signs and symptoms of hemorrhoid. In few cases hemorrhoid could result in sever bleeding which could lead to anemia.
Treatment for hemorrhoid
Sever case of hemorrhoid may need medical attention and treatment. Outpatient treatment that can be performed in a clinic or hospital include:
The procedure is performed by a doctor which includes injecting a chemical into the blood vessel to shrink the size of the hemorrhoid.
Rubber band ligation
The doctor places a special type of rubber band around the base of the hemorrhoid in order to cutoff the blood circulation, causing the hemorrhoid to shrink.
The method involves stapling the internal hemorrhoid affected tissue. The hemorrhoid shrinks within a few days. This method does not work for external hemorrhoid.
This is a surgical technique used to remove the hemorrhoids. This method completely removes the reoccurring blood clots caused by hemorrhoid both internal and external. Hemorrhoidectomy removes the excessive tissue that causes the bleeding and protrusion due to hemorrhoids.
