HbA1c - Your 3-Month Blood Sugar Average

What is HbA1c?

Hemoglobin A1c (HbA1c) measures your average blood sugar levels over the past 2-3 months. It shows the percentage of hemoglobin proteins in red blood cells that have glucose attached to them.

Why It Matters

HbA1c is crucial for:

• Diabetes diagnosis: Identifies diabetes and prediabetes
• Long-term monitoring: Shows blood sugar control over time
• Complication risk: Predicts risk of diabetes complications
• Treatment effectiveness: Evaluates if diabetes management is working

Understanding Your Results

| HbA1c Level | Category | Average Blood Glucose | |-------------|----------|----------------------| | Below 5.7% | Normal | <100 mg/dL | | 5.7% - 6.4% | Prediabetes | 100-125 mg/dL | | 6.5% or above | Diabetes | ≥126 mg/dL |

Treatment Goals

• Most adults with diabetes: <7%
• Strict control (if safe): <6.5%
• Older adults/complications: <8%
• Pregnancy: <6%

How to Improve HbA1c

Dietary Strategies

1. Choose low glycemic foods: Whole grains, legumes, non-starchy vegetables
2. Control portions: Especially carbohydrates
3. Increase fiber: Slows glucose absorption (aim for 25-30g/day)
4. Limit added sugars: Read labels carefully
5. Balance macros: Pair carbs with protein and healthy fats

Lifestyle Changes

1. Regular exercise: Both aerobic and resistance training
2. Weight management: 5-7% weight loss can significantly improve HbA1c
3. Consistent meal timing: Helps regulate blood sugar
4. Adequate sleep: 7-9 hours; poor sleep raises blood sugar
5. Stress management: Stress hormones increase glucose

Foods That Help

• High fiber: Vegetables, legumes, whole grains
• Lean proteins: Fish, chicken, tofu, eggs
• Healthy fats: Nuts, avocados, olive oil
• Cinnamon: May improve insulin sensitivity
• Apple cider vinegar: May help with post-meal glucose spikes

Factors That Affect HbA1c

Can Falsely Elevate

• Iron deficiency
• Kidney disease
• Certain medications

Can Falsely Lower

• Recent blood loss
• Hemolytic anemia
• Pregnancy
• Some genetic conditions

Monitoring Frequency

• No diabetes: Every 3 years if normal
• Prediabetes: Every 1-2 years
• Diabetes (well-controlled): Every 6 months
• Diabetes (changing treatment): Every 3 months

Beyond HbA1c

Consider complementary tests:

• Fasting glucose: Snapshot of current levels
• Continuous glucose monitor (CGM): Real-time tracking
• Fructosamine: 2-3 week average
• C-peptide: Measures insulin production

Red Flags

Seek medical attention if:
