Cortisol is named the “stress hormone,” and paradoxically, on-line discussions and movies about cortisol imbalance appear to emphasize folks out. That features me: I’ve anxiousness and, because of this, I’ve all the time puzzled about how my stress is affecting my cortisol ranges. I lastly obtained the chance to seek out out when Quest, a diagnostic info providers supplier, supplied me a complimentary Cortisol Blood Stress Hormone Take a look at.
Following my cortisol blood take a look at, I’ve spoken with a number of medical doctors to higher perceive my “excessive cortisol” outcomes and reply the query: Ought to all of us be involved about cortisol? Or are all these movies on social media stressing us out for no cause?
What’s cortisol? Does it management stress?
“Cortisol is an important hormone produced and launched by adrenal glands,” mentioned Dr. Sanjay Dixit, medical director of cardiometabolic endocrine and wellness options at Quest Diagnostics and medical professional for questhealth.com, in an e mail. “Many individuals affiliate cortisol as being the ‘stress hormone,’ however it really has many extra necessary features.”
Along with managing the physique’s response to emphasize, cortisol regulates blood sugar and blood strain, the sleep-wake cycle and metabolism whereas suppressing irritation.
“It’s mostly referred to as the ‘stress hormone’ as a result of it is launched in response to emphasize and works to organize the physique for ‘fight-or-flight,'” added Dr. Sajad Zalzala, co-founder and chief medical officer of longevity platform AgelessRx, through e mail. “It will increase glucose availability, which provides power and mobilizes saved fat and proteins to supply extra gas.”
Do you want a cortisol blood take a look at?
Dr. Dixit defined that somebody might get a cortisol take a look at to see if they’ve a cortisol deficiency, often known as adrenal insufficiency. Signs of this may embrace:
- Fatigue or being overly drained
- Worsening muscle weak point
- Pores and skin adjustments (significantly darkening in folds and scars)
- Lack of urge for food
- Unintentional weight reduction

Another excuse a cortisol take a look at could also be ordered is to see if a affected person has extra cortisol, commonly known as Cushing’s syndrome. Potential signs for this embrace:
- Bruising simply
- Unintentional weight acquire
- Muscle weak point
- Fatigue
- Rounded and rosy face
- Elevated fats within the higher again
- Impaired glucose tolerance
“[Impaired glucose tolerance is] one thing that may be significantly noticeable in sort 2 diabetic sufferers who’ve bother managing their glucose ranges even with adherence to prescribed treatment,” mentioned Dr. Dixit.
What occurs throughout a cortisol blood take a look at?
Earlier than my blood was drawn for this take a look at, I had my yearly bodily with my main care supplier. I notified her that I’d be getting this take a look at and requested to have my different preventative blood assessments taken concurrently. I need to point out this as a result of it is necessary to run any health-related assessments by a health care provider who is aware of you and your well being historical past.
In line with Quest, you have to be at the least age 18 to purchase a take a look at, which is unavailable in Alaska, Arizona or Hawaii. For choose assessments, you can be requested to reply related medical questions. Earlier than a take a look at order is submitted for processing, your buy and solutions will then be reviewed by a telemedicine physician affiliated with the nationwide clinician community PWNHealth to make sure this take a look at is medically acceptable for you.
You could additionally schedule the cortisol take a look at between 7 a.m. and 9 a.m. “Cortisol ranges naturally change all through the day,” Quest answered in an FAQ, stating that since cortisol ranges normally peak within the morning, this explicit degree could be the very best indicator of a cortisol downside.
No fasting is required. However I needed to quick for the opposite blood assessments ordered by my physician.
In line with Dr. Dixit, it’s also necessary to notice that “a blood take a look at for cortisol may be inaccurate in some instances.” Inaccurate outcomes, for instance, can occur if an individual is taking oral contraceptives or steroids, equivalent to prednisone.
As soon as I purchased the cortisol take a look at on Quest’s web site — it ordinarily prices $89 with a $6 doctor service charge — I used to be despatched an e mail with my order quantity and a hyperlink to schedule an appointment at a close-by Quest location. I scheduled my appointment for 8:20 a.m. on the facility closest to me.
On the day of my appointment, I used to be texted a hyperlink to test in after I arrived and was admitted inside 5 minutes. (I extremely suggest scheduling beforehand so you do not have to attend.) I get significantly anxious about blood assessments, so I notified my technician and requested if I might lie on an examination desk. She assured me that many individuals get nervous about blood assessments and, after I signed off on my assessments, did an amazing job speaking to me as a distraction whereas my blood was drawn.
Later that evening, I obtained the outcomes of my cortisol take a look at. As for the outcomes from the assessments ordered by my physician, I obtained them 5 days later. Quest reviews that processing instances fluctuate, however it typically takes as much as eight enterprise days to obtain outcomes.
My cortisol blood take a look at outcomes
Unsurprisingly, my cortisol blood take a look at outcomes got here again as “excessive” at 33.2 mcg/dL. Quest reviews {that a} regular vary between 7 a.m. and 9 a.m. is 4.0-22.0 mcg/dL. To be frank, this freaked me out. I had a sense that my cortisol ranges could be excessive due to my common anxiousness and heightened nerves round blood assessments, however really seeing that “excessive” consequence and never absolutely understanding it paradoxically elevated my stress ranges much more.
Quest lets you focus on your outcomes with an impartial doctor, so I took benefit of this provide. I known as Quest’s customer support line and was emailed to schedule my appointment with a doctor at PWNHealth through Everly Well being Options, a digital well being firm that acquired PWNHealth in 2021. When scheduling my appointment, I offered context about my cortisol blood take a look at. I used to be then advised {that a} doctor would name me inside 4 hours throughout enterprise hours.
Inside 4 hours, a PWNHealth doctor known as. I requested the physician if my cortisol degree was consistent with the truth that I’ve anxiousness and was burdened in regards to the blood take a look at. She mentioned that it could possibly be why my cortisol was acutely excessive, however that chronically excessive cortisol ranges could possibly be regarding and attributable to different situations, sure drugs or being pregnant. She added that it could possibly be associated to an adrenal gland situation.
I additionally requested about how excessive cortisol ranges can go and he or she acknowledged that there isn’t any “highest level,” particularly because it varies from individual to individual, relying on the situation. She added that individuals with adrenal gland situations sometimes present larger cortisol ranges, however there is not a selected cutoff.
Although the physician acknowledged that my excessive cortisol was possible on account of anxiousness, she really useful that I comply with up with my main care doctor. Afterward, I used to be in a position to obtain my Quest outcomes as a PDF and ship them to my PCP.
What are ‘regular’ cortisol ranges? Why do they modify?
“The ‘regular’ reference vary varies barely with the lab that is doing the testing,” mentioned Dr. Zalzala. “Quest reviews a standard a.m. (7 to 9 a.m.) blood degree of 4.0 to 22.0 mcg/dL, whereas Labcorp reviews regular a.m. blood degree of 6.2 to 19.4 mcg/dL.”
As for why cortisol varies all through the day: “Cortisol is essential in serving to an individual transition from sleep to wakefulness,” Dr. Zalzala defined. “This triggers a ‘morning cortisol surge’ — a fast rise in cortisol ranges inside 20 to half-hour of waking, which jumpstarts alertness and prepares the physique for the day.”
Over the course of the day, our our bodies may also expertise mini peaks in cortisol ranges to assist us keep power and application. These peaks sometimes happen round midday and within the early night. “Apparently, these peaks typically align with customary meal instances, enjoying a key function in supporting our physique’s capacity to metabolize meals and regulate power ranges,” mentioned Dr. Zalzala.
Dr. Betul Hatipoglu, MD, professor of medication at Case Western Reserve College’s College of Medication and medical director of the Diabetes and Metabolic Middle on the College Hospital Cleveland Medical Middle, acknowledged in an e mail that there’s a “regular, what we name ‘circadian rhythm’ for cortisol.” Because the day goes on, cortisol ranges will step by step lower and change into lowest nearer to bedtime.
How excessive can cortisol ranges go?
“Cortisol ranges might go as excessive as or nearer to 40 [mcg/dL] in people who’re extraordinarily unwell, equivalent to folks in intensive care,” Dr. Hatipoglu mentioned. Dr. Zalzala added {that a} regular grownup can generate cortisol ranges as much as 50 mcg/dL, which is about two to 3 instances their morning surge degree, throughout instances of stress.
Dr. Zalzala additionally talked about Cushing’s syndrome, a uncommon dysfunction during which “the adrenal gland begins making cortisol by itself (adrenal tumor) or in response to a pituitary gland tumor that makes an excessive amount of ACTH [adrenocorticotropic hormone, which regulates cortisol] and ignores the suggestions cycle.” For these with this dysfunction, cortisol ranges can go as excessive as 100 mcg/dL.
In instances the place somebody is extraordinarily unwell, equivalent to with septic shock, Dr. Zalzala acknowledged that ranges may be as excessive as 1,000 mcg/dL.
The connection between cortisol and anxiousness
I shared my outcomes with all of the medical doctors I consulted to see if I might get a greater understanding of how anxiousness might have an effect on my cortisol ranges — and every other components which may be at play.
“Excessive cortisol in a standard particular person generally is a signal of stress in your case,” mentioned Dr. Hatipoglu. “Nonetheless, typically different hormones can have an effect on the cortisol ranges. For instance, if somebody is taking oral contraceptives or estrogen remedy, this may enhance whole ldl cholesterol, which is what you might have been examined for.”
Attributable to fasting, anxiousness and being burdened about my blood draw, Dr. Zalzala mentioned that mixture might have prompted my morning cortisol degree to be larger than regular. He added, “Research have proven that stress or acute anxiousness can drive cortisol ranges considerably larger, typically to values much like what you skilled.”
Do medical doctors suggest a cortisol blood take a look at? What different cortisol assessments are there?
“I normally would test a random cortisol earlier than 9 a.m. within the morning to verify the extent isn’t low,” mentioned Dr. Hatipoglu. “If we’re involved about excessive cortisol, it’s normally really useful that we really do totally different evaluations.”
To grasp whether or not elevated cortisol ranges are a standard response or an irregular enhance, Dr. Hatipoglu might then need to do testing equivalent to a milligram dexamethasone suppression take a look at (which measures whether or not cortisol secretion by the adrenal gland may be suppressed) or a 24-hour urine cortisol take a look at (which measures the quantity of cortisol in an individual’s urine over a day). Nonetheless, if a affected person is on contraception, stopping it for a number of months after which repeating the cortisol take a look at might assist present their physique’s precise cortisol ranges.
Dr. Zalzala, however, acknowledged that he hardly ever recommends a single morning cortisol take a look at until a affected person is believed to have Addison’s or Cushing’s illness. Addison’s is a uncommon endocrine dysfunction attributable to broken adrenal glands that may’t produce sufficient hormones.
“For these individuals who need to use cortisol ranges as a instrument to make way of life changes and to watch different interventions (like remedy or sleep drugs), then the saliva cortisol degree is the one I’d suggest,” acknowledged Dr. Zalzala. “Research point out that salivary cortisol ranges present a fairly robust correlation with serum cortisol.”
For my “excessive” consequence particularly, Dr. Zalzala acknowledged, “Whereas this consequence aligns with the stress components you’ve got described, cortisol ranges above 20–25 µg/dL [which is the same as mcg/dL] within the morning can typically immediate additional analysis, significantly if signs counsel extra hormonal imbalance.”
If I had been to take supplementary assessments beneath much less worrying situations and my cortisol continues to be elevated, Dr. Zalzala mentioned I ought to discover different components with my healthcare supplier. “They might contemplate repeating the take a look at utilizing different strategies, like a 24-hour urinary free cortisol or late-night salivary cortisol take a look at, that are much less affected by instant stress responses.”
Whereas this explicit cortisol blood stress hormone take a look at generally is a good first step, Dr. Dixit acknowledges that it could not essentially be the final one. He recommended that an individual involved about their well being ought to discuss to their physician — even when the take a look at outcomes do not present something incorrect.
What occurs if a cortisol blood take a look at is irregular?
“I feel the easiest way right here could be to see a doctor, a nurse practitioner or a healthcare supplier to get an analysis,” Dr. Hatipoglu mentioned. “[This is] performed to grasp whether it is true [cortisol] elevation or is it stress-induced.”
Dr. Dixit particularly really useful that along with a main healthcare supplier, one might see an endocrinologist, a health care provider specializing in diagnosing and treating well being situations that have an effect on the endocrine system. “That is as a result of testing for extra cortisol isn’t as simple as a single blood take a look at,” he mentioned, including {that a} healthcare supplier might carry out an analysis, suggest extra assessments and contemplate different potential causes.
Nonetheless, if extra assessments stay irregular, a skilled clinician have to be consulted for additional diagnostic choices. “Most conventionally skilled physicians would initially consider for Cushing’s or Addison’s illness,” Dr. Zalzala mentioned. “If these are dominated out, an intensive clinician would then examine different contributing components affecting cortisol ranges. Conversely, a much less attentive strategy may dismiss the affected person with out addressing the underlying points.”
If a health care provider does decide that there are issues with extra cortisol or adrenal insufficiency, Dr. Dixit acknowledged that the strategies used to handle the difficulty rely on the foundation trigger. For instance, with Cushing’s syndrome, treatment or surgical procedure could also be required for the reason that dysfunction may be attributable to a tumor on the adrenal or pituitary glands.
What may cause irregular cortisol ranges?
“I feel it is helpful to speak in regards to the methods the traditional cortisol cycle may be disrupted, that might present up on salivary testing if performed on the proper instances of day,” mentioned Dr. Zalzala, who listed the next as widespread causes for a disrupted cortisol cycle:
- For cortisol ranges that stay low and flat all through the day: power stress, adrenal fatigue, burnout and a few power inflammatory situations
- For decrease morning cortisol ranges that then peak within the night: power stress, sleep issues, shift work and sure psychological well being situations (for instance, PTSD)
- For regular morning cortisol ranges that enhance within the night: anxiousness, high-stress way of life, night publicity to synthetic mild (equivalent to from screens) and late-day caffeine or high-stress actions
- For a decrease or absent rise in cortisol upon waking, or Cortisol Awakening Response): power stress, despair, PTSD, burnout and shift work
Signs of excessive cortisol or cortisol deficiency will also be linked to non-cortisol-related situations and well being points, in keeping with Dr. Dixit. That’s the reason consulting a health care provider about your outcomes and signs is important.
Irregular cortisol well being impacts
Whereas social media might oversimplify all issues cortisol as a method of clickbait, Dr. Zalzala mentioned it shouldn’t be dismissed. That is as a result of dysregulated cortisol has the next long-term well being impacts:
- Psychological well being points equivalent to anxiousness, despair and temper instability
- Cognitive impairment equivalent to reminiscence issues and impaired govt perform
- Metabolic issues that contain weight acquire and weight problems, insulin resistance, elevated danger of metabolic syndrome and sort 2 diabetes and blood sugar instability (equivalent to hypoglycemia or hyperglycemia)
- Cardiovascular points like hypertension, arterial stiffness, irritation and coronary heart illness, elevating the danger of coronary heart assaults and stroke
- Immune system impairment that may embrace elevated susceptibility to infections and autoimmune situations equivalent to rheumatoid arthritis or lupus
- Bone well being points and muscle losing like osteoporosis and muscle loss
- Sleep disruption and fatigue, together with insomnia, power fatigue, low motivation and issue managing stress
- Digestive points equivalent to gastrointestinal irritation contributing to situations like irritable bowel syndrome (IBS) and exacerbating signs of inflammatory bowel illnesses like Crohn’s illness, and gastric ulcers
Ought to folks be involved about their cortisol ranges?
The query that is on everybody’s thoughts. After mentioning all the social media movies circulating saying that individuals ought to be frightened about their cortisol ranges, I requested medical doctors if there may be any legitimacy to those claims or if it is simply fearmongering.
“I do not assume it’s honest to say folks ought to be involved about their cortisol ranges — as you may see, cortisol always fluctuates,” mentioned Dr. Hatipoglu. “The fluctuation happens so many instances that it’s typically even troublesome to know what may be very regular or very irregular.” Nonetheless, if you’re involved about your cortisol, she recommends seeing a health care provider to see if a take a look at is required first as an alternative of getting it examined randomly.
Whereas Dr. Zalzala acknowledges that there’s some reality to the idea of “minding your cortisol ranges,” since there are medical situations that may trigger irregular cortisol ranges, he believes “social media typically oversimplifies this, turning cortisol right into a scapegoat for varied well being points.” He specifies that cortisol imbalances are sometimes attributable to deeper points equivalent to poor sleep, unhealthy habits, unmanaged stress and substance abuse, during which case “cortisol is extra of a symptom than the foundation trigger.”
“Cortisol ranges, as a instrument, ought to be used along side different instruments like a CGM sensor or a sleep monitor,” concluded Dr. Zalzala.
Tips on how to naturally cut back cortisol with way of life adjustments
“I normally suggest necessary, fundamental way of life administration, [including] nutritious meals and good diet; motion train like yoga, strolling and swimming; an excellent evening’s sleep, meditation and mindfulness; good vitamin D; and stress administration for day-to-day stresses of life,” mentioned Dr. Hatipoglu. “And final, as a lot as doable, eliminating smoking and extra alcohol.”
“Decrease caffeine and sugar consumption, particularly later within the day,” Dr. Zalzala really useful. “Each can elevate cortisol and disrupt the traditional rhythm, making it tougher to wind down at evening.” Extra sugar and starch may cause a spike in blood sugar adopted by a crash. This may happen in the course of the evening, disrupting your sleep.
When you keep a constant sleep schedule and night routine with out display time or intense train (which might elevate cortisol and disrupt sleep) however nonetheless wrestle to go to sleep, Dr. Zalzala recommends delicate sleep aids like melatonin or L-theanine earlier than shifting on to robust choices like passionflower or California poppy. “If these aren’t efficient, seek the advice of a health care provider about drugs like trazodone or doxepin and rule out situations like sleep apnea,” he mentioned. “All the time focus on sleep therapies, together with OTC dietary supplements, with a health care provider.”
The takeaway
Whereas the outcomes of my cortisol blood take a look at did stress me out, I am glad I attempted it as a result of it helped me study extra about cortisol. It additionally provides me much more of an incentive to extend my stress and anxiousness administration. Whereas I’ve all the time prioritized my well being and wellness, since getting the cortisol blood take a look at, I’ve began exercising greater than earlier than, going to mattress earlier, pondering up new methods to decrease my stress ranges and paying nearer consideration to having a well-balanced food plan.
As for ordering the take a look at by Quest, I believed the method was clean, and it is good to have management over the well being assessments you may get performed (if accredited, after all). I additionally appreciated having the choice to talk with an impartial doctor about my outcomes. Nonetheless, as each Quest and the medical doctors I consulted suggested, it’s best to do any well being assessments beneath the supervision of a healthcare supplier, who can then assist with analysis and potential therapy. I am glad I advised my physician in regards to the take a look at and that it was simple to ship her my outcomes. And now, I am far more knowledgeable about what the following steps could possibly be if additional testing is required.
