At what age range is Crohn's disease most commonly diagnosed?

Crohn's disease is an inflammatory bowel disease that can affect any part of the gastrointestinal tract but is most commonly diagnosed in adolescence and young adulthood. The peak incidence typically occurs in the second decade of life, which corresponds to ages 10 to 20 years. This age range is significant because it coincides with a period of growth and development, and it is during this time that individuals may first experience symptoms that lead to a diagnosis.

The early symptoms of Crohn's disease, such as abdominal pain, diarrhea, and weight loss, often manifest during this decade, prompting medical evaluation and subsequent diagnosis. Although the disease can occur at any age, its most common diagnostic age sets the stage for subsequent management and understanding of its chronic nature, influencing treatment decisions, lifestyle modifications, and long-term care planning.

Other age ranges provided in the choices may represent rarer occurrences of diagnosis, but they do not align with the epidemiological data indicating a significant rise in diagnoses during the second decade of life.
