What If My A1C is Good But I Feel Terrible?
If your A1C test results show that your blood sugar levels are within the normal range, but you still experience symptoms like fatigue, dizziness, or mood swings, you're not alone. This phenomenon is more common than you think, and there are several reasons why it can happen.
1. Blood Sugar Spikes
Even if your A1C is within the normal range, you can still experience blood sugar spikes after meals. These spikes can cause your blood sugar to temporarily rise above the normal range, leading to symptoms like fatigue, dizziness, and mood swings.
2. Insulin Resistance
Insulin resistance occurs when your body becomes less responsive to insulin, making it harder for glucose to enter your cells. This can cause your blood sugar levels to rise, even if your A1C is within the normal range.
3. Sleep Quality
Poor sleep quality can disrupt your body's natural processes, including insulin sensitivity and glucose regulation. This can lead to symptoms like fatigue, dizziness, and mood swings, even if your A1C is within the normal range.
4. Stress Levels
Chronic stress can raise your cortisol levels, which can increase your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, high stress levels can still cause problems.
5. Medication Side Effects
Certain medications, such as steroids and some antidepressants, can raise your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, these medications can still cause problems.

6. Underlying Medical Conditions
Certain underlying medical conditions, such as polycystic ovary syndrome (PCOS) or Cushing's syndrome, can raise your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, these conditions can still cause problems.
7. Diet and Lifestyle
A diet high in processed foods, sugar, and unhealthy fats can raise your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, a poor diet and lifestyle can still cause problems.
8. Lack of Physical Activity
A sedentary lifestyle can raise your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, a lack of physical activity can still cause problems.
9. Genetic Predisposition
Some people may have a genetic predisposition to insulin resistance or other metabolic disorders, which can raise their blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, a genetic predisposition can still cause problems.
10. Other Factors
Other factors, such as dehydration, certain medications, and underlying medical conditions, can also raise your blood sugar levels and lead to symptoms like fatigue, dizziness, and mood swings. Even if your A1C is within the normal range, these factors can still cause problems.
