Recovering from adrenal fatigue and feel like your blood sugar is off? Maybe you’ve been getting shaky or “hangry” lately, or crashing hard in the afternoon. Or maybe you’re feeling more nervous and can’t tell if it’s adrenal fatigue or your blood sugar that’s to blame.
If this sounds familiar, you’re not alone. There is a strong link between blood sugar and adrenal fatigue, and it works both ways. When blood sugar is unstable, it can stress the adrenals, and when adrenal function is off, blood sugar regulation often suffers, too.
In this article, we’ll explore the link between adrenal fatigue and blood sugar from a functional medicine perspective, and what you can do to restore balance.
What is Adrenal Fatigue?
Adrenal fatigue is a term coined to describe a collection of stress-related symptoms. Fatigue, brain fog, sleep issues, and feeling “tired but wired” are some of its hallmark signs.
Functional medicine acknowledges adrenal fatigue as a real condition. However, the name isn’t entirely accurate. A more precise term for this condition is HPA axis dysfunction.
HPA-axis stands for hypothalamic-pituitary-adrenal axis. In simple terms, it’s your body’s stress response system. When you’re under stress, your hypothalamus sends alarm bells to your pituitary gland. It then triggers your adrenal glands to release stress hormones, like cortisol and adrenaline.
Normally, cortisol levels follow a predictable pattern throughout the day, much like melatonin. They rise in the morning to wake you up, and fall at night to support sleep.1 However, chronic stress can disrupt this natural rhythm. Cortisol levels can become too high, too low, or rise and fall at the wrong times.
How Cortisol Affects Blood Sugar
Cortisol is best known as your body’s main stress hormone. It rises in times of stress, giving you a burst of energy to handle threats. But what many don’t realize is that cortisol plays a key role in blood sugar regulation, too. It prevents your blood sugar from getting too low between meals or while you sleep.
Here’s how it works. When you’re stressed, cortisol levels rise. This triggers your liver to release stored glucose (glycogen) into your bloodstream.2 As glucose rises, it gives your body a shot of energy to respond to perceived threats.
Cortisol also influences blood sugar through its relationship with insulin. Insulin is the hormone that moves glucose out of your bloodstream and into your cells. When cortisol rises, your cells become less sensitive to insulin. This keeps more glucose in your blood, so you have more energy available. While this is helpful in short bursts, it’s not meant to go on nonstop.
Why Adrenal Dysfunction Can Disrupt Blood Sugar
When stress becomes chronic, your body can get stuck in a stress response pattern. The adrenals keep pumping cortisol, causing levels to stay elevated for long stretches. Over time, this can disrupt cortisol’s natural rhythms. Cortisol may be released at the wrong time, or in amounts that are too high or too low.
This pattern is often referred to as adrenal fatigue, or more accurately, HPA-axis dysfunction – and it has a direct impact on blood sugar.
Each time cortisol rises, it signals your body to release more glucose. It doesn’t matter if the perceived threat is an overdue bill, a busy schedule, or a looming work deadline. The physiological response is the same: When cortisol goes up, glucose rises, too.
While extra glucose is helpful when you’re running away from a tiger, threats these days look quite different. And when you don’t burn that extra stress glucose off, it spikes your blood sugar.
The Long-Term Impact on Blood Sugar Regulation
That’s why chronic stress can make blood sugar harder to regulate over time. If this goes on for too long, it can contribute to high blood sugar (hyperglycemia) and insulin resistance.
This explains why many people with adrenal fatigue also struggle with blood sugar issues. When cortisol becomes dysregulated, glucose often follows.
This may lead to:
- More frequent blood sugar spikes and crashes
- Reactive hypoglycemia
- Increased cravings for sugary or fatty foods
- Feeling shaky or irritable between meals
Can Blood Sugar Issues Worsen Adrenal Fatigue?
Your body sees blood sugar crashes as a form of stress.3 Each time glucose drops too low, it triggers the release of more stress hormones. Over time, your body can start to lean on cortisol to stabilize your energy. This can create a vicious cycle that’s hard to break.
When blood sugar swings happen frequently, your stress response gets activated again and again. This triggers the release of cortisol to bring your blood sugar (and energy) back up. While this response is helpful in the short-term, relying on it too much puts extra demands on your HPA axis
As a result, blood sugar instability can often reinforce adrenal fatigue symptoms. This could look like increased fatigue, irritability, or anxiety if meals are delayed or skipped. That’s why keeping your blood sugar steady is a crucial part of adrenal fatigue recovery.
How to Support Adrenal and Blood Sugar Balance
Blood sugar swings can make adrenal fatigue symptoms feel worse, and vice versa.
That’s why functional medicine takes a holistic approach to adrenal fatigue recovery. This means addressing both HPA axis dysfunction and blood sugar regulation. This approach helps you break out of the cortisol and glucose instability cycle.
Here are some key pillars to balance cortisol and glucose:
- Move regularly. Exercise reduces stress, lowers blood sugar, and improves insulin sensitivity.4 That said, intense workouts can raise cortisol, so it’s best not to overdo it. Stick to gentler forms like walking, swimming, Pilates, or light strength training.
- Manage stress. Yoga, meditation, mindfulness, and vagus nerve exercises calm the nervous system and help regulate cortisol.5 Try sprinkling these into your day, even if it’s just for a few minutes.
- Eat balanced, regular meals. Build balanced meals with a mix of protein, complex carbs, and healthy fats to prevent extreme glucose spikes. Ideally, try to eat a meal or snack every 3 hours to keep blood sugar stable. For more nutrition guidance, check out our adrenal fatigue diet guide.
- Prioritize sleep. Getting plenty of rest supports healthy cortisol rhythms and glucose regulation. Aim for at least 7-9 hours of sleep every night. If getting quality sleep is a challenge, our holistic sleep guide has loads of helpful tips.
When to Seek Functional Medicine Support
It’s normal to deal with stress or a blood sugar swing now and then. But when symptoms linger or start to interfere with your daily life, it could be a sign of a deeper imbalance.
