Symptoms of Adrenal Fatigue

If you answered yes to the above questions, it is not a normal part of aging. Instead, you might be dealing with adrenal fatigue.

In this blog post, we shall discuss some common symptoms of adrenal fatigue. But, before that, let us understand what exactly adrenal fatigue is. 

What is Adrenal Fatigue?

You can find the adrenal glands just above the kidneys. Similar to other glands in the body, they secrete a variety of hormones that regulate specific bodily functions. These glands produce essential hormones vital for survival and nonessential hormones that are significant but not crucial for sustaining life.

The adrenal glands produce cortisol, which aids in regulating metabolism and managing stress, and aldosterone, which controls blood pressure. Additionally, the adrenal glands produce adrenaline, also known as epinephrine, which provides an energy surge during fight or flight situations. 

Usually, cortisol levels are higher in the morning to aid in waking up and gradually decrease throughout the day. Conversely, melatonin (the hormone responsible for inducing sleepiness) has an inverse relationship with cortisol. When cortisol is elevated, melatonin is low, and vice versa. 

If the adrenal glands are not functioning optimally, you get adrenal fatigue, also known as adrenal insufficiency. Even the balance between cortisol and melatonin is disrupted. This can vary, as the condition may present differently in each individual. 

However, the issue does not only lie within your adrenal glands. Instead, it results from an intricate network of communication between your brain and adrenal glands known as the hypothalamic-pituitary-adrenal axis (HPA axis), commonly referred to as the brain-adrenal axis. 

Within this system, the hypothalamus releases corticotropin-releasing hormone (CRH), which signals the pituitary gland to release the adrenocorticotropic hormone (ACTH). Subsequently, ACTH instructs the adrenal cortex to release cortisol. Therefore, adrenal fatigue is essentially a dysfunction in the communication between the brain and the adrenals rather than an issue within the adrenal glands themselves.

The Symptoms of Adrenal Fatigue

If you are struggling with adrenal fatigue, you may be experiencing the following symptoms:

What Causes Adrenal Fatigue?

Adrenal fatigue originates from chronic stress, which can manifest in various ways, such as emotional stress, unhealthy eating habits, exposure to toxins, excessive exercising, inadequate sleep, food sensitivities, infections, injuries, and autoimmune conditions.

Causes Adrenal Fatigue

Excessive and prolonged exposure to stress can lead to dysfunction in the body’s stress response system. This dysfunction follows a predictable pattern and results in a set of symptoms commonly known as adrenal fatigue. 

The progression through the three stages of HPA axis dysfunction and chronic stress varies for each individual and depends on factors such as age, biological sex, co-existing conditions, and personal history. Some people may quickly reach stage 3 within a few months, while others may take years to reach that point.

Want to find out the root cause of your fatigue or stress? Opt for our Dutch test, a comprehensive test to evaluate your sex and stress hormones. It measures your hormone levels and their metabolites and specific nutrients by using dried urine analysis. Hence, it uncovers any issues that are left undetected by bloodwork alone.

How does Functional Medicine help in Managing Adrenal Fatigue?

There are many factors that may contribute to adrenal fatigue, such as diet, stress, thyroid disorders, blood sugar imbalances, poor gut health, hormone imbalances, and nutrient deficiencies. Since everyone is different and the causes of HPA axis dysfunction vary among individuals, it is highly recommended to opt for the functional treatment as it will be unique for each patient. It involves various lifestyle changes like improving nutrition, exercise, sleep habits, and stress management. 

If you suspect you are experiencing adrenal fatigue symptoms, make an appointment with a Functional Medicine Specialist who will consider your overall well-being instead of focusing on individual symptoms. They will assist in achieving optimal health and address adrenal fatigue at its root rather than relying solely on medication.  


Functional medicine assists patients in recognizing and managing HPA axis dysfunction. Additionally, it aids in discovering strategies to handle persistent stress, address inflammation, or rectify gut microbiome imbalances.
