What is true about type 1 diabetes?

Type 1 diabetes is characterized as an autoimmune condition where the body's immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas. This leads to an absolute deficiency of insulin, making individuals with type 1 diabetes insulin dependent for survival. It is most commonly diagnosed in children and young adults, though it can occur at any age. Recognizing this, the statement that it is insulin dependent and usually diagnosed in childhood accurately reflects the nature and typical onset of the condition.

Other statements indicate inaccuracies about type 1 diabetes. For instance, it is not commonly diagnosed in middle age, as that is more typical for type 2 diabetes. Additionally, while type 2 diabetes can often be managed or even reversed through lifestyle changes, type 1 cannot be cured in this manner since it involves a critical loss of insulin-producing cells. Lastly, type 1 diabetes is less prevalent than type 2 diabetes, which is more common due to factors such as obesity and lifestyle choices. Hence, the particular characteristics of type 1 diabetes affirm that it is insulin dependent and usually diagnosed in childhood.
