Which diabetes type is largely related to genetic factors and often diagnosed in youth?

Diabetes Mellitus Type 1 is primarily characterized by its strong association with genetic predisposition and early onset, often diagnosed in children and adolescents. This autoimmune condition occurs when the pancreas produces little or no insulin due to the immune system mistakenly attacking insulin-producing beta cells. The genetic component plays a crucial role in the susceptibility to Type 1 diabetes, where specific genes related to the immune system may increase the risk.

Unlike Type 2 diabetes, which is more frequently linked to lifestyle factors and often develops in adulthood, Type 1 is distinctly noted for its onset in younger populations. Gestational diabetes occurs during pregnancy and typically resolves after childbirth, while Type 4 diabetes is not an established classification and does not have the same recognition as the other types. Thus, Type 1 diabetes remains the most relevant answer when considering genetic factors and youth diagnosis.
