Capsule endoscopy is generally a procedure applied to adult patients. Although technically applicable to patients of all ages, it may not be suitable for very elderly individuals and very young children due to swallowing difficulties. The literature reports its application across a wide age range, from 8-10 month old infants to 85-year-old patients. However, in patients within these extreme age groups, the potential benefits of the procedure must be carefully evaluated, and a comprehensive preliminary assessment is required.
