what are the causes of prediabetes

Prediabetes occurs when blood sugar levels are higher than normal but not high enough to be classified as diabetes. The primary causes include:

• Insulin Resistance: The body's cells don't respond effectively to insulin, leading to elevated blood sugar levels.
• Excess Weight: Being overweight, especially with excess abdominal fat, increases the risk of insulin resistance.
• Physical Inactivity: Lack of exercise contributes to weight gain and insulin resistance.
• Unhealthy Diet: Diets high in processed foods, sugary drinks, and refined carbohydrates can lead to weight gain and higher blood sugar levels.
• Genetics: A family history of diabetes can increase the risk of prediabetes.
• Age: The risk of prediabetes increases as you get older, especially after age 45.
• Ethnicity: Certain ethnic groups, including African Americans, Hispanics, and Native Americans, are at higher risk.

Lifestyle changes, such as improving diet, increasing physical activity, and losing weight, can help prevent or delay the progression to type 2 diabetes.
