Electric bidet toilets are widely used in Japan and are sanitary devices, that are integral to daily life. Approximately, half of the population washed the anus before or after defecation. Cleaning the anus after defecation using the bidets contributes to hand hygiene and local comfort, and it may be effective against constipation. However, excessive bidet use potentially causes anal pruritus and anal incontinence (AI). Physicians are advised to instruct patients with anal pruritus to avoid excessive cleaning of the anus and those with AI to discontinue bidet use. For the estimation of the inherent severity of AI, physicians should instruct a bidet user with AI to discontinue bidet use and assess the severity of AI later. Additionally, the nozzle surface and splay water of bidet toilets may be contaminated with fecal indicator bacteria, such as Escherichia coli and Pseudomonas aeruginosa, as well as antimicrobial-resistant bacteria, rendering them a potential vehicle for cross-infection. In the hospital setting, compromised patients must be cautious regarding the shared use of bidet toilets to prevent infection by antimicrobial-resistant bacteria. Specifically, they should be provided with bidet toilets exclusive for them or may need to be instructed to not use a bidet.
