CDR Dietetic Technician, Registered (DTR) Practice Exam

The classification of diabetes primarily identifies two main types: Type 1 and Type 2 diabetes.

Type 1 diabetes is an autoimmune condition where the pancreas produces little to no insulin due to the destruction of insulin-producing beta cells. This type usually develops in children and young adults, but it can occur at any age.

Type 2 diabetes, the more prevalent form, typically arises from insulin resistance, where the body’s cells do not respond effectively to insulin, often accompanied by relative insulin deficiency. It predominantly occurs in adults, though increasing cases are found in children and adolescents due to rising obesity rates.

This classification is foundational in the field of nutrition and dietetics as it determines treatment strategies, dietary recommendations, and management of blood glucose levels. Understanding these two types allows dietetic technicians to offer informed counseling for dietary adjustments tailored to the specific needs of individuals with diabetes.
