“The adrenal glands sit above each kidney and are also known as suprarenal glands. Their size on average is around 5 cm x 2 cm and their function is to produce a variety of hormones, involved in blood pressure control and electrolyte balance (aldosterone), stress (adrenaline and noradrenaline), metabolism, immune, stress and inflammatory control (cortisol) and sex hormone production (DHEA and androstenedione which helps conversion to testosterone and Estrone (Oestrogen)).

 Social media influencers seem to offer lots of advice these days, especially on diet, lifestyle and health, often taken as “correct” by members of the public. Most professionals I know just tend to raise their eyebrows and take much of this advice with a pinch of salt.

The articles below also stresses that nonprofessional advice given on social media could take patient people down the wrong path with associated danger.

Adrenal fatigue/exhaustion is a phrase often misused by practitioners and patients. Whilst there are medical conditions that can cause an increase or decrease in adrenal hormones (and some of these are medical emergencies), chronic stress can have numerous effects on the physiology of the body and sometimes these can be measured downstream especially in regard to cortisol and DHEA levels. Both cortisol and DHEA can be measured in serum blood samples, however cortisol has a so-called diurnal variation. It tends to be high in the morning (helping us wake up and getting us out of bed) sloping down throughout the day and hopefully is at its lowest levels before we go to bed in order to allow us to have good restful sleep. Therefore, I usually test patient cortisol and DHEA via several saliva samples (throughout the day) not blood tests.

 However, from an endocrinological perspective, it is common to organise a short synacthen test, performed for adrenal insuffiency. The test is based on the measurement of serum cortisol before and after an injection of synthetic ACTH(adrenocorticotropic hormone, usually released by the pituitary gland which acts on the adrenals to stimulate cortisol production). If cortisol levels are normal after the injection of synthetic ACTH, the conclusion is adrenal insufficiency is highly unlikely. This is one of the reasons why my endocrinology colleagues have challenges with understanding the concept of adrenal exhaustion/fatigue.

However, The Endocrine Society notes on their webpage dedicated to the topic that “adrenal fatigue” as a term, relates to long-term mental, emotional, or physical stress.

Chronic stress affects the hypothalamic pituitary axis and therefore can negatively affect ACTH production which can then have a downstream effect on the adrenal glands. But the issue is mostly upstream and not because there is actually an adrenal gland problem, hence the confusion.

 Apart from testing adrenal stress responses in particular cortisol and DHEA I also tend to measure heart rate variability (HRV) in patients, in particular breathing heart wave which is the HRV which relates to our breathing pattern (therefore, we can easily manipulate it usually aiming to increase it by optimising breathing patterns). HRV measures the balance within the autonomic nervous system which controls most of our systems. Acute and chronic stress tends to upregulate the sympathetic or stress part of the autonomic nervous system which targets heart, lungs, muscles and liver conversely the parasympathetic or relaxation part of the autonomic nervous system target digestive function, hormones of reproduction and the immune system with increasing research suggesting a big impact on the gut microbiome.

My go to management for these types of stress relate problems having a secondary impact on the adrenals tends to be breathing, stress management, dietary change especially glucose regulation and short-term nutritional supplementation. Osteopathic Manual Treatment (OMT) can also be used on several areas of the body to physiologically support overactive stress responses.”

While TikTok overflows with images of influencers making “adrenal cocktails” to combat what they call adrenal fatigue, the Endocrine Society says, “no scientific proof exists to support adrenal fatigue as a true medical condition.”

Even before influencers began touting it on social media, a 2016 systematic review concluded that there is “no substantiation that adrenal fatigue” is an actual medical condition. Therefore, adrenal fatigue is still a myth.

Lynette Nieman, MD, Senior Investigator and Chief of the Endocrinology Consultation Service at the National Institutes of Health Clinical Center, Bethesda, Maryland, concurs.

“There is no scientific evidence that adrenal fatigue exists or causes [general] fatigue, depression, or the many common symptoms that are said to result from this condition,” she told Medscape Medical News via email.

Still, the term has gained currency among not only social media influencers who blame it for everything from cortisol surges to oestrogen imbalances but also functional and integrative medical practitioners as an explanation for chronic dysfunction related to stress.

Adrenal Fatigue, Burnout, or Adrenal Insufficiency?

Rather than “adrenal fatigue,” Marcelo Campos, MD, a primary care doctor at Atrius Health, said he prefers the medical term “burnout.”

Use of “burnout” shifts attention to the brain’s role in stress-related chronic dysfunction rather than the adrenal glands, said Campos, who also teaches at Harvard Medical School, Cambridge, Massachusetts.

More specifically still, the focuses might shift to the stress-response via the hypothalamic-pituitary-adrenocortical axis and its role in reducing levels of these cortisol and dehydroepiandrosterone sulphate.

He points out that part of the reason for the misuse of the term adrenal fatigue arises from the fact that burnout is often only associated with work stress.

“Recently, the ICD-11 [International Classification of Diseases-11] recognized burnout as a disease but focused only on work stress as a cause. The truth is that people can be burned out for many other reasons,” said Campos.

The Endocrine Society notes on their webpage dedicated to the topic that “adrenal fatigue” as a term, relates to long-term mental, emotional, or physical stress.

“The problem is not the adrenals — it is the exposure to stress in the brain. The brain — only one organ — is responsible for 40% of energy consumption in the body. As you can imagine, if you are under constant stress, you run out of gas very quickly and cannot function well,” he explained.

Adrenal fatigue theory suggests that, under stress, the adrenal glands produce too many short bursts of cortisol resulting in overall reduced cortisol levels and a feeling of being drained.

“As with many other psychiatric diseases, we do not have a way to measure biomarkers in the brain. The testing for cortisol does not work because it fluctuates too much from time to time. So, it is not reliable or reproducible,” Campos said.

This leads to the ongoing question of the best way to test and diagnose adrenal fatigue, whether it should be via blood, urine and/or saliva. And even if that is determined, there are still questions about the best time to test, how often, what the normal ranges are and how reliable the tests are.

While adrenal fatigue is not a recognized condition, adrenal insufficiency is medically recognized, resulting from an inability of the adrenal glands to make the life-essential hormones aldosterone and/or cortisol, with symptoms that include fatigue, belly pain, nausea, vomiting, diahorrhea, and joint aches.

“Adrenal cocktails are not an effective treatment for adrenal insufficiency because they do not replace the missing hormones,” Nieman stated, pointing out that anyone with symptoms of adrenal insufficiency needs to see an endocrinologist.

Pratibha Rao, MD, MPH, an endocrinologist at the Cleveland Clinic, Ohio, and medical director of the Adrenal Center at Cleveland Clinic, agreed, advising that if people continue to feel exhausted beyond their normal exertion, then they should get checked for signs of adrenal insufficiency.

“In primary adrenal insufficiency, you can actually start seeing darkening of the gums and of the skin on the palms of the hands or the soles of your feet. Sometimes people can feel dizzy or experience some loss of consciousness,” she said. “If it’s sudden and severe, you may crave salt or have extreme heat or cold intolerance.”

Recognizing and Managing Patient Frustration

The lack of formal diagnostic criteria and medical evidence, however, doesn’t mean that such symptoms as fatigue and depression don’t present, often causing significant distress for patients. While the symptoms might not be associated with the adrenal glands, they still need addressing — but how that is done is, in essence, a bone of contention.

Rao empathizes with the situation that many people, often young women, find themselves in.

“Patients are frustrated. They’ve gone to multiple doctors across the country, and they feel convinced they have adrenal fatigue, but no medical doctor has endorsed it. They end up coming to us with a cry that has so often gone unanswered.”

This issue also highlights that there are millions of people experiencing mental, emotional, and physical distress of unknown cause who seek help, many of whom believe it is related to their adrenal gland function.

But rather than turning to a social media cure, Rao stresses that people would benefit more from paying greater attention to following a healthy lifestyle than regularly consuming sugar-rich drinks claimed to offer a solution. Adrenal cocktails are energy-rich, frothy blends of orange juice, coconut milk, cream of tartar, and Himalayan salt.

“We truly are what we eat, and we are what we think,” she noted.

The body is a miraculous machine, but “we forget that it does need maintenance,” Rao said. “Up to age 30, the body is so forgiving with drugs, alcohol, or whatever insult we do to it, but after the third decade, slowly every cell starts to degenerate instead of growing. We start to see the ill or beneficial effects of lifestyle habits.”

“We insult the body, and then we say, ‘oh, I have fatigue’ and seek a quick fix,” she added. “Everyone wants instant gratification.”

Rao cautioned that adrenal cocktails could be dangerous for someone who has other medical conditions.

“If someone has kidney disease, uncontrolled hypertension, or diabetes, for example, then adrenal cocktails are definitely not safe,” Rao said. “Loading up with potassium and sodium, which is found in high quantities in adrenal cocktails, will actually worsen any kidney damage, while consuming so much sugar will cause an unregulated rise in blood sugar and further damage in someone with diabetes.”

Rao also stressed that nonprofessional advice given on social media could take patient people down the wrong path with associated danger.
