At what age does Type 1 Diabetes typically occur?

Type 1 diabetes typically occurs in younger populations, and it is most commonly diagnosed in children, teenagers, and young adults, which aligns with the under 40 years age range. This autoimmune condition results from the body's immune system attacking and destroying the insulin-producing beta cells in the pancreas, leading to a lack of insulin. While it can happen at any age—making it possible for those older than 40 to develop the condition—the majority of cases are detected before this age.

The classification of Type 1 diabetes predominantly reflects the onset occurring prior to adulthood, highlighting the age group under 40 as a key demographic. Therefore, identifying that Type 1 diabetes typically occurs in this age range accurately captures the common epidemiological trends associated with the disease.
