Feeling anxious can affect more than just your mood. It can influence sleep, appetite, energy levels, and even blood sugar. If you’ve noticed higher glucose readings during stressful periods, you’re not imagining it.
The answer is yes. Anxiety can temporarily raise blood sugar levels, even in people without diabetes. This happens because anxiety activates the body’s stress response and causes the release of hormones that increase glucose levels.
How Does Anxiety Raise Blood Sugar?
When you’re anxious, your body switches into “fight-or-flight” mode. Stress hormones such as cortisol and adrenaline are released, preparing your body to deal with danger.
One of the ways your body responds is by releasing stored glucose from the liver into the bloodstream. This provides quick energy, but it can also lead to higher blood sugar readings.
For most people, these changes are temporary. Once stress levels decrease, blood sugar usually returns to normal.

Can Anxiety Raise Blood Sugar Without Diabetes?
Yes.
Even people without diabetes may experience temporary increases in blood sugar during periods of stress or anxiety. This is sometimes called stress hyperglycemia.
Occasional spikes are usually harmless and settle once the stressful event passes. However, persistent high blood sugar should always be discussed with a healthcare professional.
Why Anxiety Can Affect People With Diabetes More
Stress hormones can make the body less sensitive to insulin, making it harder to control blood sugar levels.
Anxiety may also affect daily habits, leading to:
- Poor sleep
- Missed meals
- Less physical activity
- Difficulty following medication schedules
Together, these factors can contribute to higher glucose readings and make diabetes management more challenging.
Can Panic Attacks Increase Blood Sugar?
Yes.
Panic attacks trigger the release of adrenaline and cortisol, which may temporarily increase blood sugar levels. Some people notice elevated readings after episodes of severe anxiety or panic.
Symptoms such as sweating, rapid heartbeat, trembling, and dizziness can overlap with symptoms of both anxiety and blood sugar fluctuations, making it difficult to tell the difference without checking your glucose levels.
How to Reduce Anxiety-Related Blood Sugar Spikes
Managing stress can help support healthy blood sugar levels.
Get Enough Sleep
Poor sleep raises stress hormones and may make blood sugar harder to control.
Stay Physically Active
Even a short walk can help lower stress and improve insulin sensitivity.
Practice Relaxation Techniques
Deep breathing exercises, meditation, and mindfulness can help calm the body’s stress response.
Stay Hydrated
Dehydration may contribute to higher blood sugar readings.
Follow Your Treatment Plan
If you have diabetes, maintaining regular meals, medications, and glucose monitoring is especially important during stressful periods.
When Should You See a Doctor?
Occasional stress-related increases in blood sugar are common. However, speak with your healthcare provider if:
- Blood sugar remains consistently high.
- Anxiety or panic attacks are frequent.
- Glucose levels are becoming difficult to control.
- You experience symptoms such as excessive thirst, frequent urination, or unexplained weight loss.
Frequently Asked Questions
Can anxiety raise fasting blood sugar?
Yes. Stress hormones and poor sleep associated with anxiety may contribute to higher fasting blood sugar levels.
How long do stress-related blood sugar spikes last?
Most stress-induced spikes are temporary and improve once stress hormone levels decrease. However, chronic stress can affect blood sugar over longer periods.
Can anxiety cause low blood sugar?
Anxiety itself usually raises blood sugar. However, skipped meals or diabetes medications may increase the risk of low blood sugar.
Final Thoughts
Anxiety and blood sugar are closely connected through the body’s stress response. Temporary increases are common and usually improve as stress levels decrease.
Paying attention to sleep, exercise, hydration, and stress management can help support better glucose control and overall health.
