Unfortunately, type 1 diabetes is common and not preventable. Type 1 affects the body in a negative way by not producing insulin. In contrast type 2, considered an increasingly grave dilemma in the United States, is preventable. In type 2 diabetes insulin is not used proportionately and blood sugar level rise to extreme levels causing ill effects. Furthermore, type 2 diabetes is the most common diabetes in the United States. For this reason, ask your doctor about your next routine checkup if there are any concerns you should be aware of and secondly, take preventive measures.
