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.
