If the movement is insufficient, intestinal peristalsis slows down, feces downward slow or due to habitual constipation, thus compression of the veins, so that the local congestion and blood reflux obstacles, caused by hemorrhoidal vein pressure, venous wall resistance is reduced, can also lead to hemorrhoids incidence increased. According to clinical observation and statistical census results analysis, the prevalence of different occupations in patients with significant differences, clinical cadres, automobile drivers, salesmen, teachers, the prevalence of significantly higher. Hemorrhoids located in the mucous membrane inside the anus are called “internal hemorrhoids” and those located near the inside of the anal opening are called “external hemorrhoids”, and those that have both are called “mixed hemorrhoids”.
