Causes Of Hemroids
The main cause of hemroids is due to constipation which causes an increase in the pressure that is applied to the veins and tissue in the rectal area. The extra pressure forces more blood into the veins and extra force is exerted on the vein walls. This causes swelling and tissue damage which is experienced as an itching and irritated sensation around the anus. If the pressure is allowed to continue without treatment, enough damage may be done that causes the hemroids to bleed, and then become infected.
Other causes of Hemroids:
Pregnancy
Pregnancy increases the chances that a women may get hemroids. This is because of hormonal changes and the extra pressure that the fetus puts on the uterus. It is common for women who have never had hemroids to first experience them when they are pregnant.
Hemroids after childbirth is also very common, even if none were present during the pregnancy. These hemroids are usually due to extensive straining during delivery. Post pregnancy hormone changes also contribute to an increase in constipation, which as explained above, is the primary cause of hemroids.
Postponing Bowel Movements
Whatever the reasons, some people will habitually hold there bowel movement until it is convenient to pass. This can cause hemroids because the longer the stool sits in the large intestine, the dryer and harder it becomes. Trying to pass this type of stool causes straining when going to the bathroom. Postponing bowel movements once and a while will not do any harm, but it is important not to make it a regular habit.
Diseases
There are also some diseases that cause hemroids. One serious condition that can cause hemroids is rectal cancer. This is because rectal cancer causes a person to have “false alarms” when it comes to going to the bathroom. This in turn causes them to go more often and strain.
Alcoholics also tend to have problems with hemroids. Excessive alcohol consumption enlarges the liver. An enlarged liver puts extra pressure on the rectal veins which causes them to swell. Alcoholic also tend to be dehydrated which contributes to dry stools, and thus straining.
Other diseases that cause hemroids may be IBS (Irritable Bowel Syndrome) or intestinal tumors. These diseases cause constipation or complicate normal stool elimination.
