Chapter 1: What is Type 2 Diabetes?

Defining Type 2 Diabetes: Type 2 diabetes is a chronic metabolic disorder characterized by high blood sugar levels (hyperglycemia). Unlike Type 1 diabetes, where the body does not produce insulin, individuals with Type 2 diabetes produce insulin, but their bodies do not use it effectively. This is called insulin resistance.

How It Differs from Type 1 Diabetes: Type 1 diabetes is an autoimmune condition in which the immune system attacks and destroys insulin-producing beta cells in the pancreas. People with Type 1 diabetes require lifelong insulin therapy. Type 2 diabetes typically develops in adulthood, and while insulin resistance is a key factor, the pancreas still produces some insulin.

Causes of Type 2 Diabetes

Genetics and Family History: A family history of Type 2 diabetes can increase your risk, suggesting a genetic predisposition. However, lifestyle factors also play a significant role.

Lifestyle Factors: Unhealthy lifestyle choices, including poor diet, lack of physical activity, and obesity, are major contributors to Type 2 diabetes. These factors can lead to insulin resistance over time.

Obesity and Insulin Resistance: Excess body fat, particularly around the abdomen, is strongly associated with insulin resistance. Fat cells release chemicals that interfere with insulin's action.

Symptoms of Type 2 Diabetes

Early Warning Signs: Common early symptoms include increased thirst, frequent urination, fatigue, blurred vision, and slow wound healing. Some individuals may not experience symptoms initially.

Complications from Uncontrolled Diabetes: When left untreated or poorly managed, Type 2 diabetes can lead to serious complications, such as heart disease, kidney damage, neuropathy, retinopathy, and foot ulcers.

Risk Factors

Age and Gender: The risk of Type 2 diabetes increases with age, particularly after 45. Men and women have a similar risk, although it may manifest differently.

Ethnicity: Certain ethnic groups, including African Americans, Hispanic Americans, Native Americans, and Asian Americans, are at higher risk.

Sedentary Lifestyle: Lack of physical activity and prolonged sitting are risk factors. Regular exercise helps improve insulin sensitivity.

Poor Diet: Diets high in sugar, unhealthy fats, and processed foods contribute to the development of Type 2 diabetes.

Diagnosis and Screening

Blood Glucose Tests: Blood tests, including fasting blood sugar tests and oral glucose tolerance tests, are used for diagnosis. Elevated levels may indicate diabetes.

A1C Test: This blood test provides an average of blood sugar levels over several months, offering a more comprehensive picture of glycemic control.

Fasting Blood Sugar Test: A fasting blood sugar level of 126 milligrams per deciliter (mg/dL) or higher is indicative of diabetes.
