1. Type 1 diabetes

2. Type 2 diabetes

3. Pre-diabetes

4. Gestational diabetes

The correct answer is: Type 2 diabetes

Type 2 diabetes is indeed the most common form of diabetes, accounting for around 90-95% of all diagnosed cases. This condition typically develops in adults, although it is increasingly being diagnosed in children and adolescents due to rising obesity rates. Type 2 diabetes is characterized by insulin resistance, where the body either does not use insulin properly or does not produce enough insulin to maintain normal glucose levels. Factors contributing to the development of type 2 diabetes include genetics, lifestyle choices, such as diet and lack of physical activity, and obesity. Understanding the prevalence of type 2 diabetes is crucial for both healthcare providers and individuals, as early detection and lifestyle modifications can significantly improve outcomes and prevent complications associated with the disease.
