One of the common health reasons people use bidets at home is to relieve the symptoms caused by hemorrhoids. In the past, physicians have expressed concerns that the frequent use of bidet toilet seats causes hemorrhoids or urogenital infection, but these claims remain highly controversial and many further studies are still required. Now, a new study carried out in Japan atttempts to examine more closely the relationship between bidet toilet use and incidence of hemorrhoids or urogential infections.
As you may already know, bidet toilet use is quite common in Japan. According to the study, approximately 77.5% of households in Japan own an all in one bidet toilet. It has a relatively high rate of use in Eastern countries but in the midst of globalization, Western countries are likely to look at the bidet seat as a way to improve quality of personal hygiene in the rest room. So studies such as this one and others in the future are important to examine the relationships between bidet usage and human health. In this study, a total of 7637 female and male subjects were analyzed. Among the subjects, 4272 (55.9%) were classified as “habitual users” and 3365 (44.1%) were classified as “non-habitual” users.
What we found interesting, first of all, was that the habitual users were “more likely to be old, married, wealthy, and have a lower constipation rate (female), a higher menopausal rate (female) and higher sexual activity (female)”. We suspect that this is information that will appeal to both physicians and manufacturers alike, as the latter will be able to make products better suited for this demographic. To demonstrate, the Toto bidet seats made by Toto who is the leading Japanese manufacturer of bidet seats has new models that include things intended for senior users – such as a night light and automatic open and close toilet seat lid – as well as things for female users – such as an adjustable front wash. What else did the study find? The main finding was that hemorrhoids and urogenital infections were not causally related to bidet toilet use. Rather, people who experience discomfort in the anal or genital areas may prefer to use a bidet toilet. To us this suggests that there are advantages to using bidets to relieve symptoms causing discomfort. It did however find that bacterial vaginitis might be caused by using the bidet toilet seat, though because of the low incidence further studies would be needed in this area.
Final notes: The study can be found on the National Center for Biotechnology Information website. The title of the study is called “Bidet toilet use and incidence of hemorrhoids or urogenital infections”. It was sponsored by the Japan Sanitary Equipment Industry.
