You know that feeling when you are exhausted, but somehow also buzzing like you have swallowed a tiny espresso fueled squirrel?

You are tired, but you cannot sleep.
You are doing “all the right things,” but your energy is still flat.
You are eating well, but your blood sugar feels dramatic.
You are trying to lose weight, but your body seems to be clinging on for dear life.

First of all, your body is not being difficult for fun.

It is not broken.
It is not lazy.
It is not secretly plotting against you while you sleep.

Although, sometimes it does feel suspicious.

What may be happening is that your stress response system is struggling to find its rhythm again.

This system is called the HPA axis, which stands for hypothalamic pituitary adrenal axis. It is one of the key communication systems between your brain, hormones, nervous system, immune system, and metabolism. In other words, it is not a tiny side character. It is very much running the group chat.

What is the HPA axis?

The HPA axis is the communication pathway between your brain and adrenal glands.

When your brain perceives stress, your hypothalamus signals your pituitary gland, which then signals your adrenal glands to release cortisol. Cortisol is one of your main stress hormones. Around 15 minutes after stress begins, cortisol can rise systemically and may stay elevated for hours.

This is not a bad thing.

Cortisol helps you respond to life. It helps mobilize energy, maintain blood sugar, support alertness, manage inflammation, and keep you functioning when things get demanding.

The problem is not cortisol itself.

The problem is when your body feels like life is one long emergency meeting that could have been an email.

“Adrenal fatigue” is not quite the right term

You may have heard the term adrenal fatigue. It is commonly used, but it is not the most accurate description.

A better way to think about it is HPA axis dysregulation. That means the communication between your brain, adrenal glands, hormones, and feedback loops is not working as smoothly as it should. The concept of “adrenal fatigue” is considered outdated, but the symptoms people experience are very real.

This can look like:

• Feeling stressed, overwhelmed, or unable to relax

• Feeling exhausted or burned out

• Feeling tired but wired at night

• Trouble falling asleep or staying asleep

• Waking tired after a full night’s sleep

• Needing coffee, sweets, or snacks to function

• Low exercise tolerance

• Weight gain around the middle

• Low libido

• Brain fog

• Poor immune resilience

• Blood sugar dips even when eating “well”

In clinic, this is where I often see people blame themselves.

They say things like:

“I just need more discipline.”
“I should be able to handle this.”
“My body is out of control.”
“I must be doing something wrong.”

But often, your body is not failing you. It is responding to the amount of stress, pressure, inflammation, restriction, poor sleep, caffeine, and general life chaos it has been trying to carry.

Your nervous system has two main modes

Your autonomic nervous system has two main branches.

The sympathetic nervous system is your fight or flight system. It helps you mobilize energy, stay alert, and respond to demands.

The parasympathetic nervous system is your rest and digest system. It supports digestion, repair, immune function, recovery, and restoration.

You need both.

The issue is not that fight or flight exists. The issue is when your body gets stuck there.

Because while fight or flight is excellent for escaping danger, meeting deadlines, protecting your children, dealing with emergencies, and finding your phone when it is already in your hand, it is not where your body does its best healing.

Modern stress is not always obvious

Stress is not just big life events.

Yes, stress can be divorce, grief, childbirth, financial pressure, illness, or major change. But it can also be the daily drip of overwork, lack of downtime, perfectionism, poor sleep, blood sugar crashes, inflammation, chronic pain, over exercising, under eating, and constantly feeling like you are behind.

It can also be emotional stress that has become so normal you do not even recognize it as stress anymore.

This matters because your body responds not just to what is happening, but to how safe or unsafe it perceives life to be. It is how we perceive an event, not only the severity of the event itself, that helps generate a stress response.

So no, you are not being dramatic.

Your body may simply be keeping receipts.

Cortisol and the gut

Stress can also affect digestion in a big way.

When cortisol is high for too long, the body becomes more catabolic. That means it starts breaking things down to free up fuel. This can include glycogen, muscle tissue, bone minerals, and even amino acids from the gut lining.

The gut lining is supposed to act like a protective barrier. When that barrier becomes compromised, it may contribute to nutrient deficiencies, systemic inflammation, immune activation, and gut dysbiosis.

This is why stress is never “just in your head.”

Your brain, gut, immune system, hormones, and nervous system are all in conversation with each other. Sometimes that conversation is calm and productive. Sometimes it is a full family WhatsApp thread at 11:47 pm.

Cortisol and inflammation

Cortisol is one of the body’s most powerful anti inflammatory hormones. But both low cortisol and long term high cortisol can contribute to inflammation becoming poorly regulated. If the body is under chronic stress, cortisol may stop working as effectively, which can allow inflammation and pain to continue.

This is one reason HPA axis dysregulation can show up alongside inflammatory conditions, autoimmune patterns, chronic pain, digestive issues, metabolic dysfunction, fatigue, and mood changes.

Again, your body is not randomly throwing symptoms around for attention.

It is communicating.

Loudly, perhaps.
In all caps, perhaps.
But communicating.

Cortisol and weight loss

This is where we need to have a gentle but honest conversation.

If your body is under significant stress, weight loss may not be the first thing it wants to do.

The ongoing pursuit of weight loss can itself become a stressor. There is a time to attempt weight loss and a time not to attempt weight loss, depending on your context, hormones, and stress load.

When your body feels unsafe, it may hold onto weight as a form of protection. Not because it hates you. Not because you lack willpower. Not because your metabolism has personally betrayed you.

Because your body is asking, “Are we okay?”

If you have a long history of dieting, restriction, fasting, over exercising, or constantly trying to shrink your body, your body may not feel confident that food and safety are consistent. In that case, the starting point may actually be eating enough, stabilizing blood sugar, sleeping better, reducing stress load, and rebuilding trust with your body.

Annoying? Maybe.

Important? Very.

What actually supports the adrenal and stress response system?

Supporting the HPA axis is not about one magic supplement. If only...

It is about sending repeated signals of safety and nourishment to the body.

Food matters here. Nutrient dense foods that may support adrenal function include liver or organ meats (come on, be brave), shellfish (obviously avoid if you have an allergy), pumpkin seeds, vitamin C rich foods, nutrient rich starches, fatty fish, and sea salt.

Some of the big ones:

Vitamin C rich foods
Citrus, kiwi, strawberries, peppers, broccoli, kale, and rosehip tea can support adrenal needs, as vitamin C is used quickly under stress.

Nutrient rich starches
Sweet potatoes, squash, potatoes, fruit, legumes, rice, quinoa, millet, and other whole food carbohydrates can be important. Very low carbohydrate diets are often not ideal when someone is already depleted or stressed.

Fatty fish
Think SMASHT - Salmon, mackerel, anchovies, sardines, herring, and trout provide omega 3 fats, which may help reduce inflammatory burden and lower the demand on cortisol as an anti inflammatory hormone.

Minerals and salt
For some people eating a mostly whole foods diet, adequate mineral intake and sea salt may support adrenal function, especially when symptoms like low blood pressure, dizziness, or salt cravings are present.

Why testing can be helpful

Symptoms can give us clues, but they do not always tell the full story.

Two people can both feel exhausted, anxious, and unable to sleep, but one may have high cortisol, another may have low cortisol, another may have low DHEA, and another may have an altered cortisol rhythm across the day. Each of these would have a different treatment strategy.

This is why functional testing can sometimes be useful. It can help us understand what your body is actually doing, rather than guessing based on symptoms alone.

And truly, your symptoms deserve more than a guess.

The real goal: helping your body feel safe again

If your body has been living in stress mode, healing is not about forcing it harder.

It is about working with it.

That may mean:

• Eating enough food

• Stabilizing blood sugar

• Reducing excessive caffeine

• Sleeping more consistently

• Pausing intense exercise temporarily

• Adding restorative movement

• Addressing gut inflammation

• Supporting mineral intake

• Looking at unresolved stress patterns

• Building in actual rest

• Testing when appropriate

• Letting go of the idea that pushing harder is always the answer

Your body is not asking you to become perfect.

It is asking you to listen.

And if your body has been whispering for a while, then shouting, then throwing symptoms around like confetti at a very inconvenient party, it may be time to stop blaming it and start asking better questions.

Not, “How do I force my body into submission?”

But, “What is my body trying to protect me from?”

That is where the real work begins.
