Cortisol & Your Gut: Finding the Balance

If you’re constantly battling fatigue, stubborn belly bloat, sugar cravings, and feeling wired but tired at night, you’ve likely tried everything. You might even blame your gut - and you’d be partially right.
But what if I told you the root cause might not be created in your gut at all?
As gut health experts, we see this story often. Clients come to us focused on their digestive symptoms, but we sometimes discover that one of the root causes of their distress is a tiny but mighty hormone: cortisol.
When your cortisol is out of balance, you feel it everywhere - especially in your gut. Let’s break down why.
What is Cortisol (And Why Do We Need It)?
Cortisol is your body’s main stress hormone, produced by your adrenal glands. Think of it as your built-in alarm system. In acute doses, it’s lifesaving.
In a perfect world, cortisol follows a beautiful daily rhythm, known as a diurnal rhythm:
Morning: It peaks to help you wake up, feel alert, and tackle the day (like a natural cup of coffee).
Afternoon: It gradually begins to decline.
Evening/Night: It reaches its lowest point, allowing your body to wind down and sleep deeply.
This rhythm is crucial for energy, metabolism, immune function, and - you guessed it - healthy digestion.
How You "Feel It" When Cortisol Is Off
We don’t live in a perfect world. Chronic stress - from work, relationships, poor sleep, or even a hidden gut infection - can force your body to pump out cortisol non-stop. This leads to two main dysfunctional patterns:
1. High Cortisol (The "Wired But Tired" State)
This is often the first stage of burnout. Your alarm system is stuck in the "on" position.
You might feel: Anxious, irritable, unable to "shut your brain off" at night, craving salty or sugary foods, experiencing belly fat accumulation (especially around the waist), and dealing with bloating and digestive discomfort.
2. Low Cortisol (The "Burnt Out & Exhausted" State)
After running on overdrive for too long, your adrenal glands can become fatigued and struggle to produce enough cortisol.
You might feel: Completely exhausted (even after a full night's sleep), unable to handle stress, dizzy when standing up quickly, relying on caffeine just to get through the day, and having a weakened immune system.
The Gut-Cortisol Connection: A Vicious Cycle
This is where our expertise comes in. Your gut and your cortisol levels are in a constant two-way conversation. This is known as the gut-brain-adrenal axis. More on the gut-brain here.
Stress → Gut Issues: High cortisol directly disrupts gut function. It can weaken the intestinal lining (contributing to leaky gut), alter your gut microbiome (killing off good bacteria), decrease digestive enzyme production, and slow gut motility (hello, bloating and constipation).
Gut Issues → More Stress: An inflamed, unhappy gut sends distress signals back to the brain via the vagus nerve, which can further stimulate cortisol release. It’s a vicious cycle that keeps you stuck.
You can be eating the perfect "gut-healthy" diet, but if your cortisol is dysregulated, you will still struggle to heal.
5 Ways to Balance Cortisol and Heal Your Gut
The goal isn’t to eliminate cortisol - it’s to support your body’s ability to manage it effectively. Here’s how to start:
1. Embrace Rhythm Regulation: Your body craves predictability.
Action: Try to wake up, eat meals, and go to bed around the same time each day. This helps reinforce that natural cortisol (and as a bonus, circadian) rhythm.
2. Master Your Morning: How you start your day sets your cortisol tone.
Action: Avoid your phone for the first 60 minutes of your day. Instead, try 5 minutes of daylight exposure, gentle movement (a walk, stretching), and a protein-rich breakfast to stabilize blood sugar.
3. Choose Cortisol-Conscious Movement: More is not always better. Intense exercise can be another stressor on the body.
Action: Swap chronic cardio for walking, yoga, pilates, or strength training. Listen to your body - on high-stress days, rest is productive.
4. Support with Adaptogens: These are herbs that help your body adapt to stress.
Consider: Ashwagandha (for overall balance), Rhodiola (for fatigue), and Holy Basil (for a sense of calm). Always consult with a practitioner before starting new supplements.
5. Nourish Your Nervous System: This is non-negotiable.
Action: Incorporate daily "doses" of calm: 5 minutes of deep belly breathing, a gratitude practice, or listening to a calming podcast. This signals safety to your body, lowering cortisol.
When "Doing It All" Isn't Enough: The Role of Functional Testing
If you’ve been trying all the things and still feel off, it’s not your fault. Underlying gut issues are often the hidden driver of cortisol dysfunction.
SIBO or gut infections can create constant internal stress.
Dysbiosis (an imbalance of good vs. bad bacteria) can fuel inflammation.
Leaky Gut can allow particles into the bloodstream that keep your immune system - and cortisol - on high alert.
This is where guesswork fails and data becomes power.
At Gut Check, we aim to get to the root causes of your symptoms, and sometimes the path leads us to balancing hormones. We conduct functional testing when necessary, such as targeted labs, the Dutch test, and GI-MAP stool test, which are considered the gold standard for identifying common, hidden root causes. Using these results, your health history, and current symptoms, we can see more clearly what’s happening in your body, allowing us to create a personalized protocol to address it - not just manage the symptoms.
