Hemorrhoids are caused by excess pressure in the blood vessels in the pelvis and anus. Pressure causes blood to pool in the vessels, which makes them swell. The swollen blood vessels then stretch the tissue surrounding the blood vessels, forming a hemorrhoid that is pea to grape sized. The hemorrhoids can be in the form of internal or prolapsed hemorrhoid.  The causes of the pressure that can lead to the formation of hemorrhoids are varied.

Excess Straining During Bowel Movements

The most common cause of excess pressure on the blood vessels of the anus is straining during bowel movements. When you strain to expel feces, you are putting pressure on the blood vessels. Trying to rush a bowel movement is one reason why people may use excess force. Constipation also causes strain during a bowel movement because the stool is often hard, large, and compacted, which makes it harder to expel. Diarrhea is another common cause of excessive straining during a bowel movement. Not emptying your bowels when you feel the need to can also cause larger, harder stools that are difficult to expel.

Pregnancy and Childbirth

Pregnancy can also increase pressure in the blood vessels of the anus. Hormonal changes cause more blood to flow to the pelvic area, including the anus. In addition, the growing fetus also puts pressure on the blood vessels, making hemorrhoids common in a pregnant woman’s third trimester. Many pregnant women also get hemorrhoids during vaginal delivery. When a woman is pushing to deliver her baby, she is also putting excessive pressure on her anus, which can cause the blood vessels to swell.

Excess Weight

Carrying extra weight, particularly around the abdomen, hips, or buttocks, can also increase pressure on the pelvis and anus, increasing the chance of hemorrhoids. The more excess weight a person has, the greater the chance of getting hemorrhoids and the harder it will be to treat them. Lack of exercise coinciding with excess weight also contributes to pressure on the anus, as weak abdominal and back muscles cause a person to put more weight on their pelvis, hips, and anus.

Medical Conditions

Certain medical conditions, particularly those affecting the vascular system, can also contribute to swollen blood vessels. If a person has poor circulation, then blood will pool in areas such as the pelvis rather than being circulated throughout the body at normal rates. When blood pools in the pelvis and anal region the swollen blood vessels can develop into hemorrhoids. Liver disease can also cause blood to pool in the pelvic region, causing hemorrhoids. For more information visit :- http://hemorrhoidremediesonline.com
