What is a Dangerous Level of A1c?

Testing for diabetes is crucial for early detection and management of the condition. Diabetes, if left untreated, can lead to severe complications like heart disease, kidney failure, and nerve damage. Regular testing allows individuals to monitor their blood sugar levels, enabling timely adjustments in diet, exercise, and medication.

Various methods are available for testing sugar levels, including fasting blood sugar tests, oral glucose tolerance tests, and HbA1c tests, which provide different insights into blood sugar control over time. Additionally, continuous glucose monitoring systems offer real-time data for better management of diabetes on a day-to-day basis. In this article, we’ll shed major light on HbA1c testing, what is a dangerous level of A1c, and its significance in diabetes management.

What Is An HbA1c Test?

According to the Centers for Disease Control and Prevention, the HbA1c test, also known as glycated hemoglobin, measures average blood sugar levels over the past 3 months. It assesses how much glucose is bound to hemoglobin in red blood cells, reflecting long-term blood sugar control. To perform the test, a healthcare professional draws a blood sample, usually from a vein in the arm. No special preparation, such as fasting, is typically required. The HbA1c test is valuable in diabetes management, providing insight into overall blood sugar control and helping healthcare providers adjust treatment plans accordingly. To find out what is a dangerous level of A1c and to do something about it, it’s important to understand the significance of the test.

When Should One Plan On Taking An HbA1c Test?

Planning on taking an HbA1c test starts way before finding what A1c level is dangerous. Taking an HbA1c test becomes important when you start experiencing certain changes in your health. Following are the signs and symptoms that indicate that there’s a need for you to get your HbA1c level checked:

  • Increased thirst: Feeling unusually thirsty, even after drinking fluids.
  • Frequent urination: Needing to urinate more often than usual, especially at night.
  • Unexplained weight loss: Losing weight without trying, despite normal eating habits.
  • Fatigue: Feeling unusually tired or exhausted, even with adequate rest.
  • Blurred vision: Experiencing blurry or distorted vision, potentially affecting daily activities.
  • Slow-healing wounds: Wounds or cuts taking longer than usual to heal.
  • Tingling or numbness: Sensations of tingling or numbness, especially in the hands or feet.
  • Frequent infections: Experiencing recurrent infections, such as urinary tract infections or skin infections.
  • Darkened skin patches: Developing patches of darkened skin, particularly in areas of folds or creases.
  • Risk factors: Having a family history of diabetes, being overweight or obese, leading a sedentary lifestyle, having high blood pressure, or being diagnosed with prediabetes.

Other than these signs, as per the CDC guidelines, it’s recommended to undergo A1c testing if:

  • You’re 45 years or above, regardless of any apparent diabetes symptoms.
  • If you’re under 45, overweight or obese, and possess at least one risk factor for prediabetes or diabetes, like a family history of diabetes or engaging in physical activity less than three times a week.

What A1C Level Is Dangerous?

what is a dangerous level of a1c

A1c levels indicate average blood sugar levels over the past 2-3 months. According to the National Institutes of Health, the following are the different levels of HbA1c:

  • Normal levels are below 5.7%
  • Prediabetes is indicated by levels between 5.7% and 6.4%
  • Diabetes is diagnosed at 6.5% or higher

Moreover, the A1c levels can go way beyond 7 or 8%. According to WebMD, the dangerous HbA1c levels are when they cross the 9% mark. Above 9% HbA1c levels, the intensity of complications grows significantly. Following are the diabetes complications one might face when the A1c levels exceed 9%.

  • Increased risk of cardiovascular diseases such as heart attacks and strokes.
  • Nerve damage (neuropathy) leads to numbness, tingling, or pain in the extremities.
  • Eye damage (retinopathy) results in vision problems or blindness.
  • Kidney damage (nephropathy) leads to kidney failure.
  • Poor wound healing and increased susceptibility to infections.
  • Higher risk of foot ulcers and amputations due to nerve and blood vessel damage.

What To Do When You Have HbA1c Dangerous Levels?

When you know what is a dangerous level of A1c and you fall in that range (9%), a mindful, planned approach involving dietary changes, regular HbA1c testing, and utilizing Continuous Glucose Monitoring (CGM) can significantly improve management and outcomes.

Firstly, dietary modifications play a pivotal role. Focus on whole foods such as fruits, vegetables, lean proteins, and healthy fats while minimising refined carbohydrates and sugary snacks. Portion control, increasing fiber intake, and monitoring sugar consumption are essential. Hydration and reducing alcohol intake are also vital components.

Secondly, upon knowing what a1c level is dangerous and you are at risk, regular HbA1c testing becomes essential to monitor average blood sugar levels over time. It provides insights into treatment effectiveness and guides adjustments in diet, exercise, and medication.

Thirdly, incorporating CGM technology offers real-time data on blood sugar levels, identifying patterns, trends, and fluctuations throughout the day and night. This detailed information allows for informed decision-making regarding lifestyle adjustments and medication management. CGM also provides alerts for high or low blood sugar levels, enhancing overall diabetes management and reducing the risk of complications.

When you know what is the danger level of a1c, it’s imperative not to rely solely on dietary changes and technology. Collaboration with healthcare providers is essential for gradual medication adjustments while focusing on natural health restoration. Patients should follow their doctor’s advice to taper medication slowly while putting full focus on regaining health naturally.

Finding what is the danger level of a1c is essential, but its more important to do something about that. Maintaining healthy blood sugar levels is essential for managing diabetes and preventing complications. Regular testing, particularly through the HbA1c test, provides valuable insights into long-term blood sugar control. Recognising symptoms and risk factors prompt timely testing, enabling early detection and intervention.

A dangerous level of HbA1c exceeding 9% significantly increases the risk of complications such as cardiovascular diseases, nerve damage, and kidney dysfunction. However, addressing these levels requires a multifaceted approach. Gradual dietary changes, regular HbA1c testing, and utilising CGM technology offer comprehensive strategies for managing blood sugar levels effectively.

It’s crucial to work closely with healthcare professionals to tailor treatment plans, including medication adjustments while focusing on natural health restoration. By incorporating these strategies and seeking professional guidance, individuals can take proactive steps towards better diabetes management and improved overall health and well-being.
