National Diabetes Awareness Month



November is National Diabetes Awareness Month. Across the nation organizations and communities come together to bring awareness and educate others about diabetes. For an in-depth understanding of diabetes, visit our blog titled, “Prevention and Management of Diabetes.” For the year 2021, the focus of National Diabetes Awareness Month is on prediabetes and preventing diabetes. Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough to be diagnosed with type 2 diabetes. According to the CDC, an estimated 88 million American adults have prediabetes and 84% of American adults with prediabetes do not know they have it. Type 2 diabetes will develop if one has prediabetes unless lifestyle changes are made. Type 2 diabetes can cause long term damage to the heart, blood vessels, and kidneys. Lifestyle changes to help prevent the long-term damage of type 2 diabetes, includes eating healthy foods, staying physically active as part of a daily routine, and staying at a healthy weight. All of these lifestyle changes aid in bringing blood sugar levels back to normal. If you are concerned about diabetes, please talk to your doctor immediately. You can ask your doctor for a blood sugar screening to make sure you are at a healthy, safe level. To celebrate, National Diabetes Awareness Month, you can educate yourself on diabetes, donate funds to critical research developing life-changing treatment for those living with diabetes, and advocate for those living with diabetes to ensure everyone has access to the resources they need. Millions of Americans are in the fight of their lives against diabetes. Whether you’re fighting diabetes yourself or on behalf of a loved one or a stranger, it is important to make a difference in any way you can.
