Hemorrhoids can develop inside the rectal area or they can protrude outside the body. A hemorrhoid is the result of swelling in the anus or rectum, explains FamilyDoctor.org. This condition is often caused by constipation, frequent diarrhea and weight placed on the abdominal and intestinal area. The symptoms include pain, itching and bleeding. Hemorrhoids are not usually a serious health concern, but they can be extremely painful.
Constipation
Constipation can cause a hemorrhoid to develop due to straining and the passing of hard stools. Once the hemorrhoid develops, constipation can irritate the tissues and cause bleeding. Veins are sensitive as it is, and further straining and passing of hard stools can break the skin, allowing the vein to bleed.
Diarrhea
Frequent diarrhea can irritate the skin of the anus, especially if a hemorrhoid develops. Once a hemorrhoid appears, more diarrhea only increases the chances of the skin cracking and bleeding. GICare.com explains that when a person has a bowel movement, the body pushes blood to the rectal area to activate the digestive system. This increases the volume of blood available to the veins. The blood is close to the surface, making even the smallest crack bleed quite profusely in some cases.
Itching
Hemorrhoids are often itchy. Many over-the-counter and natural remedies are useful for reducing this discomfort. Wiping too hard after a bowel movement or scratching the hemorrhoid can rupture the skin, leading to bleeding.
Weakened Tissues
BleedingHemorrhoids.org points out that poor posture, weakened rectal vein walls and poor muscle tone are all possible causes of bleeding hemorrhoids. Pregnancy and excess weight can cause tissue weakness in the rectal area. This can make it harder for hemorrhoids to shrink and heal. When the veins are swollen, such as from pressure placed on the intestines from the extra weight, bleeding can occur quite easily.
