Various Causes of Hemorrhoids
There are many factors that may contribute to the development of hemorrhoids. The kind of occupation a person has and a person’s body weight is among the factors that will contribute to the possible development of hemorrhoids.
The veins inside the anus will be swollen if there is some pressure within the veins that will prevent the flow of blood back to the heart. When a person is constipated, these swollen veins will become constricted due to the large amount of stool inside the rectum.
Sitting for a long time can also produce hemorrhoids in a person, just like standing for a long time can cause varicose veins of the leg. Sitting a long time on the toilet bowl and straining for the bowel movement can also produce hemorrhoids. Chronic diarrhea can also cause hemorrhoids.
The increase of intra-abdominal pressure can also cause hemorrhoids. Some activities that can increase intra-abdominal pressure are heavy lifting and chronic cough due to asthma, any chronic lung disease, or smoking. This increased intra-abdominal pressure can obstruct the blood flow in the veins that can result into swelling of the veins.
Obesity is one factor that can increase the intra-abdominal pressure because of the excessive weight of the abdominal wall. Obesity is always associated with hemorrhoids. Hemorrhoids are common to pregnant women. Pregnancy will produce swollen veins that will result to hemorrhoids because of the moderately increasing volume of blood. Pregnancy can also slightly block the blood flow of some veins from the rectum and lower pelvis.
Rectoceles is also associated with hemorrhoids. Hemorrhoids happen when the rectal wall will protrude out of the vagina thus obstructing the veins below the wall of the rectum.
When a person has some swollen veins in the rectum and is scratched by a hard stool during bowel movement, a bright red bleeding in the rectum may occur. Oftentimes, this is a painless bleeding. The red blood will be seen in the toilet bowl water or on the tissue paper.
Mostly, all bright red bleeding of the rectum is cause by hemorrhoids. But the possibility of a rectal cancer is not set aside. A rectal examination by a doctor is always recommended when there is a bleeding of the rectum.
There are two sets of anorectal veins that can become involved in hemorrhoids: the external and internal hemorrhoidal veins. The external veins are just located inside the anal sphincter. The internal veins are located slightly higher up inside the rectum.
Hemorrhoids will be very painful when an internal vein prolapsed and then it falls through the muscles of the anal sphincter. The veins will become distended thus causing the pain. The painful feeling of hemorrhoids are mostly caused by the prolapsed internal or external veins that are already swollen.
These things that have been pointed out as causes hemorrhoids in people. It is better to watch out for these things that hemorrhoids may be properly diagnosed or otherwise prevented.
