Grade II Hemroids 

Postponing bowel movement
Sometimes when "nature calls", there is no toilet nearby. Usually, by postponing bowel movement, the urge to defecate goes away and does not return until after eating another meal. While occassionally postponing bowel movement does no harm, doing it regularly can contribute to hemroids. 


Here's why: the longer fecal matter remains in the colon, the drier it becomes and therefore the harder it is to pass without straining. Repeated inhbition of the urge to defecate can also result in weaker signals to the rectal muscles to pass stool. Eventually, it may be difficult to pass stool naturally without some straining.

Also, a colon filled with fecal matters is heavy and exerts pressure on the blood vessels and veins of the Excretory Orifice and rectum. This can cause these veins to swell and become hemroids.

Diseases
There are several diseases that can actually lead to the development of hemroids. Of these, the most serious is rectal cancer, which causes a false "call of nature", thus encouraging the patient to go to the bathroom and strain unnecessarily.

Enlargement of the liver, often found in people who abuse alcohol, can create extra pressure on the hemroidsal veins. Other digestive diseases, such as intestinal tumor and irritable bowel syndrome, can interefere with normal elimination or cause constipation.

Lastly, although heart attack does not cause hemroids, it does increase venous pressure and therefore can make an existing hemroids worse.
