What is the underlying pathophysiology of Type 1 Diabetes?

The underlying pathophysiology of Type 1 Diabetes is primarily characterized by the autoimmune destruction of beta cells in the pancreas. In this condition, the body's immune system mistakenly attacks and destroys these insulin-producing cells, leading to a significant deficiency of insulin. This lack of insulin results in elevated blood glucose levels, as insulin is crucial for facilitating the uptake of glucose into cells for energy.

Type 1 Diabetes usually manifests in childhood or adolescence, although it can occur at any age. The autoimmune nature of this disease is supported by the presence of specific antibodies targeting pancreatic islet cells, which can often be detected in affected individuals.

In contrast to Type 1 Diabetes, other types of diabetes such as Type 2 are primarily associated with insulin resistance or other metabolic factors. For example, insulin resistance involves the body's cells becoming less responsive to insulin, and excess insulin production or insulin deficiency due to obesity are factors more closely related to Type 2 Diabetes. This distinction highlights the importance of recognizing the unique pathophysiological mechanisms that differentiate Type 1 from other forms of diabetes.
