Hemorrhoids probably result from increased venous pressure in the hemorrhoidal plexus. Predisposing factors include occupations that require prolonged standing or sitting; straining due to constipation, diarrhea, coughing, sneezing, or vomiting; heart failure; hepatic disease, such as cirrhosis, amebic abscesses, or hepatitis; alcoholism; anorectal infections; loss of muscle tone due to old age, rectal surgery, or episiotomy; anal intercourse; and pregnancy.
