Type 1 and type 2 diabetes are two distinct conditions that share a common feature: elevated blood sugar levels. However, the underlying causes, risk factors, and treatment approaches for these two types of diabetes differ significantly.
Type 1 diabetes, previously known as juvenile diabetes or insulin-dependent diabetes, is an autoimmune disorder in which the body’s immune system attacks and destroys the insulin-producing beta cells in the pancreas. Insulin is a hormone that allows glucose to enter cells for energy production. Without insulin, blood sugar levels rise, leading to the symptoms of diabetes, such as frequent urination, thirst, and unexplained weight loss.
Type 2 diabetes, previously known as adult-onset or non-insulin-dependent diabetes, is characterized by insulin resistance, a condition in which the body’s cells do not respond properly to insulin. As a result, glucose builds up in the blood, leading to the development of type 2 diabetes. Risk factors for type 2 diabetes include obesity, physical inactivity, and a family history of the condition.
The main difference between type 1 and type 2 diabetes lies in the underlying cause of the condition. Type 1 diabetes is an autoimmune disorder, while type 2 diabetes is caused by insulin resistance. This difference has implications for treatment, as type 1 diabetes requires insulin therapy, whereas type 2 diabetes can often be managed with lifestyle changes, such as diet and exercise, and oral medications.
