Type 2 diabetes is caused either by an insufficient production of insulin or by a condition known as insulin resistance. As of 2015, the mechanism for developing Type 2 diabetes remains unknown, although experts consider genetic and environmental factors as possible triggers for the disease, states Mayo Clinic.
Diabetes mellitus is a family of metabolic disorders that involve excessive blood sugar levels. Type 2 diabetes accounts for an estimated 90 to 95 percent of reported diabetes cases in the United States, reports the U.S. Centers for Disease Control and Prevention.
Normally, the pancreas secretes the hormone insulin to enable the body to absorb blood glucose into the cells for energy production. Due to a combination of genetic tendency and lifestyle choices, the body may not respond properly and form a resistance to insulin, which may result in Type 2 diabetes developing.
The likelihood of acquiring Type 2 diabetes from parents diagnosed with the disease is not 100 percent. As of 2015, scientists are still unable to identify the gene that carries the risk for developing the condition, notes Endocrine Web.
Engaging in regular physical workout and eating a healthy, balanced diet may reduce the likelihood of developing Type 2 diabetes, although an individual is genetically susceptible to the disease. Leading a sedentary lifestyle and indulging in unhealthy food choices may result in obesity, which is strongly associated with Type 2 diabetes.
