Type 1 and Type 2 Diabetes: What’s the Difference?

Expert Verified Solution:

Type 1 Diabetes: Type 1 diabetes is an autoimmune condition where the body’s immune system attacks and destroys the insulin-producing cells in the pancreas. This results in little or no insulin production. People with Type 1 diabetes require daily insulin injections or the use of an insulin pump to manage their blood sugar levels. It is typically diagnosed in children and young adults, though it can develop at any age. The exact cause is not known, but it is believed to involve genetic and environmental factors.

Type 2 Diabetes: Type 2 diabetes is characterized by insulin resistance, where the body’s cells do not respond properly to insulin, and/or a relative lack of insulin production. Unlike Type 1, Type 2 diabetes is more common in adults, though increasing numbers of children and adolescents are being diagnosed due to rising obesity rates. Type 2 diabetes is often associated with lifestyle factors such as obesity, poor diet, and physical inactivity. Management typically involves lifestyle changes such as diet and exercise, along with medications that help control blood sugar levels. In some cases, insulin therapy may be needed.

Key Differences:

Onset: Type 1 diabetes usually develops in children or young adults, while Type 2 diabetes is more common in adults, particularly those over 45, though it is increasingly seen in younger populations.

Cause: Type 1 is an autoimmune condition with no known prevention, whereas Type 2 is influenced by lifestyle factors and is often preventable.

Treatment: Type 1 requires insulin therapy from diagnosis, while Type 2 can often be managed with lifestyle changes and oral medications before insulin is needed.

Understanding these differences is crucial for proper management and treatment of each type of diabetes.
