IBD affects patients of all ages, but onset is often during the first 2–3 decades of life. Consequently, the diagnosis often coincides with the time in life when individuals are developing relationships and becoming sexually active. It is well recognised that chronic diseases can impact on sexual function. Unfortunately, this subject is rarely discussed with IBD patients in busy clinics, despite increasing evidence that it affects them. Various factors impact on sexual function including psychological factors (anxiety, depression, and body image), disease activity and symptoms, medications, and sexual health. Discussing concerns and problems with patients is important, and there are simple measures that can be advised, and resources available, to help these patients remain in successful relationships.
