I am 29Y old. I have diabetic Type 2. Recently my sugar level was increased to 150 (fasting). I do exercise and eat whole grains. why this happening?

If you have Type 2 diabetes and are experiencing high fasting blood sugar levels, despite exercising and eating whole grains, there are several potential reasons to consider:

Insulin Resistance or Inadequate Insulin Production

Type 2 diabetes is characterized by insulin resistance, where your body does not respond well to insulin, and over time, it may also involve inadequate insulin production. This can lead to high blood sugar levels, especially in the morning due to overnight hormonal changes25.

Dawn Phenomenon

The dawn phenomenon is a common issue in diabetes management, where the body's natural increase in hormones such as cortisol and growth hormone during the night causes the liver to release glucose into the bloodstream, leading to higher morning blood sugar levels45.

Medication Timing and Dosage

If you are taking medications like metformin, the timing and dosage might not be optimized for controlling your fasting blood sugar levels. For example, adjusting the timing of your metformin to better target your fasting levels could be beneficial3.

Diet and Meal Timing

Although you are eating whole grains, the overall composition of your diet and the timing of your meals can still impact your blood sugar levels. Consuming high-carbohydrate foods, even if they are whole grains, can cause spikes in blood sugar. Additionally, eating dinner too late in the evening can affect your morning blood sugar levels5.

Physical Activity

While regular exercise is beneficial, it can sometimes have variable effects on blood sugar levels. For instance, if you are experiencing insulin resistance, physical activity might not lower your blood sugar as effectively as it should3.

Other Factors

Other factors such as stress, sleep quality, and certain medications (e.g., corticosteroids, estrogens) can also influence your blood sugar levels1.

Recommendations

• Consult Your Doctor: Discuss your medication regimen with your healthcare provider to see if adjustments are needed.
• Dietary Adjustments: Focus on a balanced diet with plenty of fiber-rich foods, non-starchy vegetables, and high-protein foods. Limit sugar and salt intake and consider the timing of your meals23.
• Monitor and Adjust: Use continuous glucose monitoring or regular blood sugar tests to understand how different foods and activities affect your blood sugar levels.
• Exercise Timing: Pay attention to how exercise affects your blood sugar levels and adjust your routine accordingly.
• Stress and Sleep: Manage stress and ensure good sleep quality, as these factors can impact blood sugar control.

By addressing these potential factors and working closely with your healthcare team, you can better manage your fasting blood sugar levels.
