Your body often sends subtle signals when something is off, and some of these early signs can point to serious health conditions like prediabetes. One such sign is darkened skin, which may occur in people with higher-than-normal blood sugar levels. Recognizing these changes early can help prevent prediabetes from progressing into full-blown diabetes.
Understanding Prediabetes
Prediabetes is a condition where blood sugar levels are elevated but not high enough to be classified as diabetes. The American Diabetes Association identifies two key indicators of prediabetes: Impaired Glucose Tolerance (IGT) and Impaired Fasting Glucose (IFG). As of 2021, 9.1% of adults worldwide had IGT, and 5.8% had IFG. Worryingly, projections estimate that by 2045, these figures will rise to 638 million and 414 million, respectively, with a large portion of this growth occurring in low-income countries.
Skin Changes: A Sign of Prediabetes
Dr. Anusha Nadig, Consultant Endocrinologist at Fortis Hospital, Bengaluru, explains that darkened skin, particularly in areas such as the armpits, neck, and back, is often a sign of prediabetes. This condition, known as acanthosis nigricans, results from elevated insulin levels that prompt skin cells to grow faster, leading to a thickened and darker appearance.
The U.S. Centers for Disease Control and Prevention (CDC) notes that prediabetes occurs when the body’s cells don’t respond properly to insulin, which helps sugar enter the cells for energy. In response, the pancreas produces more insulin, leading to higher blood sugar levels. If left unmanaged, this can develop into type 2 diabetes.
Lack of Symptoms and Regular Check-Ups
According to Dr. Nadig, many individuals with prediabetes may not experience noticeable symptoms, making regular check-ups essential. Blood sugar levels should be tested every 3 to 6 months based on a healthcare provider’s advice. Family history, obesity, lack of physical activity, and age over 45 are common risk factors.
Preventing the Progression to Diabetes
Lifestyle changes are key to halting the progression of prediabetes. Dr. Nadig suggests that a 7% reduction in body weight can lower the risk of type 2 diabetes by 58%. Additionally, engaging in moderate-intensity exercise for at least 150 minutes a week and adopting healthier eating habits can make a significant difference.
Other preventive measures include quitting smoking, managing stress, and addressing sleep disorders. Following a Mediterranean diet, reducing added sugars, and focusing on complex carbohydrates and vegetables are dietary strategies that help reverse prediabetes. Consulting a dietitian or nutritionist can assist in developing personalized eating plans tailored to individual needs.
Recognizing early signs of prediabetes, such as darkened skin, and making necessary lifestyle adjustments can effectively reduce the risk of progressing to diabetes.
