- The exact prevalence of hemorrhoids is difficult to establish as most people do not seek care.
- US data from the 1990’s suggest that hemorrhoids affect 4.4% of the population. (Ganz 2013; Sun et al. 2016)
- Peak prevalence occurs between age of 45 to 65 years among both men and women. (Lohsiriwat 2012; Sun et al. 2016).
- As well, hemorrhoids are very common during pregnancy especially in the third trimester. It has been estimated that 25% of pregnant women experience hemorrhoids. (Zielinski et al. 2015)
