Different Types of Hemorrhoids
Hemorrhoids are tissues that are actually filled with the blood vessels, which usually line the anus and the rectum. Generally the term hemorrhoid is used to refer to the inflammation of the veins of the anus and rectum. Any condition that puts strain or excessive pressure on the rectal walls, usually can cause hemorrhoids. Usually this is because, the increased pressure on rectal walls causes the hemorrhoids vessels or the veins to swell and bulge out. This condition is referred as piles. Let us now have a look at the different types of hemorrhoids.
DIFFERENT TYPES OF HEMORRHOIDS
Internal Hemorrhoids
When enlargement and inflammation of the hemorrhoids vessels happens within the rectal canal, the condition is referred as internal hemorrhoids. Internal hemorrhoids usually occur where there is too much pressure occurring on the internal hemorrhoids veins. The only visible sign of the internal hemorrhoids that is usually seen is the presence of bright-red blood which appear on the surface of the stool. Pain is not usually very common with internal hemorrhoids, not unless an infectious occurs or a blood clot forms.External Hemorrhoids
When inflammation and enlargement of the hemorrhoids vessels happens under the skin around the anus, the condition is referred as external hemorrhoids. These swollen veins usually bleed easily, either as a result of rubbing or straining. Irritation from the drain mucus may result in itching in the area around the anal. If blood clots happens to form in these type of hemorrhoids, it may result in a very severe pain occurring.CAUSES OF HEMORRHOIDS
Any condition that can strain or put excessive pressure on the rectal can cause piles or hemorrhoids. Such conditions include diarrhea, constipation, rectal or anal infection, cirrhosis of the liver, portal hypertension, coughing, etc.Research has proved that a sedentary lifestyle, most especially sitting for a continuous long period of time can easily initiate hemorrhoids development. Another risky factor is obesity. This is because it is usually associated with pressure increase on the rectal vein.
In pregnancy, hemorrhoids can also be a common occurrence. This may be due to hypertension or increased strain during the process of bowel movement.
