Type 1 Diabetes is primarily characterized by the destruction of beta islet cells in the pancreas, which leads to a significant deficiency of insulin. This autoimmune condition typically occurs when the immune system mistakenly attacks and destroys these insulin-producing cells. As a result, individuals with Type 1 Diabetes can no longer produce adequate amounts of insulin, which is essential for regulating blood glucose levels.

The condition often presents in childhood or young adulthood, although it can occur at any age. Unlike other forms of diabetes, such as Type 2, which is commonly associated with insulin resistance and obesity, Type 1 is distinct in its immediate insulin dependency due to the lack of insulin production.

It's important to recognize that the characteristics mentioned in other options don't apply to Type 1 Diabetes. For instance, insulin resistance along with obesity is more closely linked to Type 2 Diabetes, whereas the age of onset for Type 1 Diabetes typically happens well before age 40 for most patients. Additionally, Type 1 Diabetes is not characterized by an overproduction of glucagon; rather, the issue revolves around insufficient insulin to balance glucose levels appropriately. Understanding these distinctions is crucial for accurately diagnosing and managing diabetes in a clinical setting.
