10 million people in the United States complained of hemorrhoids, corresponding to a prevalence rate of 4.4%.

In both genders, a peak in prevalence was noted from age 45-65yrs, with a subsequent decrease after age 65 yr.

The development of hemorrhoids before age 20 yr was unusual.

This was in contrast to the epidemiology of constipation, which demonstrated an exponential increase in prevalence after age 65 yr and was more common in blacks and in families with low incomes or low social status.
