Type 2 Diabetes: Comprehensive Guide to Prevention, Risk Factors, & Early Detection

 Diabetes Type 2:

Type 2 diabetes is a chronic metabolic disorder characterized by elevated blood sugar levels. It is the most common type of diabetes, accounting for 90-95% of cases. Unlike type 1 diabetes, where the body's immune system destroys insulin-producing cells, type 2 diabetes develops due to insulin resistance and relative insulin deficiency.

Risk Factors:

Several factors increase the risk of developing type 2 diabetes:

• Overweight or Obesity: Excess body fat, especially around the abdomen, is a major risk factor for type 2 diabetes.
• Physical Inactivity: Lack of regular physical activity can contribute to insulin resistance.
• Family History: Having a parent or sibling with type 2 diabetes increases the risk.
• Age: The risk increases with age, especially after 45.
• Ethnicity: Certain ethnicities, such as African Americans, Hispanic/Latinos, American Indians, Asian Americans, and Pacific Islanders, are at higher risk.
• Prediabetes: People with prediabetes have higher than normal blood sugar levels and are at increased risk of developing type 2 diabetes.
• Gestational Diabetes: Women who had gestational diabetes during pregnancy are at higher risk of developing type 2 diabetes later in life.
• Other Factors: Polycystic ovary syndrome (PCOS), non-alcoholic fatty liver disease (NAFLD), and certain medications can also increase the risk.

Prevention:

While not everyone can prevent type 2 diabetes, lifestyle changes can significantly reduce the risk:

• Maintain a Healthy Weight: Losing even a small amount of weight (5-7% of body weight) can have a significant impact on reducing the risk.
• Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity exercise per week, spread over at least 3 days.
• Healthy Eating: Choose a diet rich in fruits, vegetables, whole grains, and lean protein. Limit sugary drinks, processed foods, and saturated and unhealthy fats.

Screening:

The American Diabetes Association recommends screening for type 2 diabetes in adults with the following risk factors:

• Overweight or obesity (BMI ≥ 25 kg/m²) and one or more additional risk factors.
• All adults aged 45 years or older, regardless of weight or other risk factors.

Early detection and treatment are crucial for preventing complications of type 2 diabetes.
