How to know if you have high cortisol?
High cortisol causes weight gain, fatigue, mood changes, and sleep issues. Testing through saliva, blood, or urine can confirm elevated levels and guide treatment.
Cortisol, often called the "stress hormone," plays a crucial role in your body's fight-or-flight response and helps regulate everything from blood sugar to inflammation. While cortisol is essential for survival, chronically elevated levels can wreak havoc on your health, leading to a cascade of symptoms that affect your physical and mental well-being. Understanding the signs of high cortisol and knowing when to get tested can be the key to reclaiming your health and vitality.
High cortisol levels can develop gradually, making symptoms easy to dismiss as everyday stress or aging. However, recognizing these warning signs early and taking action through proper testing can help prevent more serious health complications down the road.
Understanding Cortisol and Its Normal Function
Cortisol is produced by your adrenal glands, which sit atop your kidneys. This hormone follows a natural daily rhythm called the circadian cycle, typically peaking in the early morning to help you wake up and gradually declining throughout the day to prepare your body for sleep.
Normal vs. Elevated Cortisol Patterns Throughout the Day
| Time of Day | Normal Cortisol Pattern | High Cortisol Pattern | Associated Symptoms | |
|---|---|---|---|---|
| Morning (6-8 AM) | Morning (6-8 AM) | High (peak levels) | Extremely high or low | Difficulty waking up or feeling wired |
| Afternoon (12-4 PM) | Afternoon (12-4 PM) | Moderate (declining) | Elevated or erratic | Energy crashes or anxiety |
| Evening (6-10 PM) | Evening (6-10 PM) | Low (preparing for sleep) | Elevated | Difficulty falling asleep, feeling wired |
| Night (10 PM-6 AM) | Night (10 PM-6 AM) | Lowest levels | Elevated or disrupted | Frequent awakenings, poor sleep quality |
Cortisol should follow a natural daily rhythm, peaking in the morning and declining throughout the day. Disrupted patterns can indicate cortisol imbalances.
Under normal circumstances, cortisol helps your body respond to stress by increasing blood sugar, suppressing the immune system temporarily, and enhancing your brain's use of glucose. It also plays important roles in regulating blood pressure, reducing inflammation, and maintaining proper metabolism.
When Cortisol Becomes Problematic
Problems arise when cortisol levels remain consistently elevated due to chronic stress, medical conditions, or other factors. This state, known as hypercortisolism, can disrupt nearly every system in your body and lead to a condition called Cushing's syndrome in severe cases.
Physical Signs of High Cortisol
High cortisol levels manifest through various physical symptoms that can significantly impact your quality of life. These signs often develop gradually and may be mistaken for other health issues.
Weight Changes and Body Composition
One of the most noticeable signs of elevated cortisol is unexplained weight gain, particularly around the midsection. High cortisol promotes fat storage in the abdominal area while breaking down muscle tissue. You may notice:
- Central obesity with fat accumulation around the waist and upper back
- A "moon face" appearance due to facial fat deposits
- Purple or pink stretch marks on the abdomen, thighs, or arms
- Muscle weakness and loss of muscle mass
- Difficulty losing weight despite diet and exercise efforts
Skin and Hair Changes
Elevated cortisol affects your skin's ability to heal and maintain its structure. Common skin-related symptoms include:
- Easy bruising and slow wound healing
- Thinning skin that tears easily
- Acne breakouts, especially in adults
- Hair loss or thinning hair
- Excessive hair growth in women (hirsutism)
Mental and Emotional Symptoms
High cortisol significantly impacts brain function and emotional regulation. The mental health effects of elevated cortisol can be particularly distressing and may include:
- Persistent anxiety and feeling "wired but tired"
- Depression and mood swings
- Irritability and difficulty controlling emotions
- Brain fog and difficulty concentrating
- Memory problems and forgetfulness
- Feeling overwhelmed by everyday tasks
These symptoms often create a vicious cycle where mental distress leads to more stress, further elevating cortisol levels and worsening symptoms.
Sleep and Energy Disruptions
Cortisol's natural rhythm is closely tied to your sleep-wake cycle. When levels are chronically elevated, this rhythm becomes disrupted, leading to:
- Difficulty falling asleep despite feeling exhausted
- Frequent nighttime awakenings
- Waking up feeling unrefreshed
- Energy crashes in the afternoon
- Feeling "tired but wired" in the evening
- Relying on caffeine or stimulants to function
Understanding your cortisol patterns throughout the day can provide valuable insights into whether elevated levels are disrupting your sleep and energy cycles.

Other Health Effects of Elevated Cortisol
Beyond the primary symptoms, high cortisol can affect multiple body systems:
Immune System Suppression
Chronically elevated cortisol suppresses immune function, making you more susceptible to infections, colds, and illnesses. You may notice that you get sick more frequently or take longer to recover from minor illnesses.
Cardiovascular and Metabolic Effects
High cortisol can contribute to:
- High blood pressure
- Elevated blood sugar levels
- Increased risk of diabetes
- High cholesterol levels
- Irregular menstrual periods in women
- Decreased libido and sexual dysfunction
Testing Options for Cortisol Levels
If you suspect you have high cortisol based on your symptoms, several testing methods can help confirm elevated levels and guide treatment decisions.
Saliva Testing
Saliva testing is often considered the gold standard for measuring cortisol because it reflects the active, unbound hormone that's available to your tissues. This method is particularly useful for:
- Measuring cortisol at multiple time points throughout the day
- Assessing your natural cortisol rhythm
- Convenient at-home collection
- Detecting subtle imbalances that blood tests might miss
A typical saliva cortisol test involves collecting samples at three key times: morning (upon waking), afternoon, and evening. This provides a comprehensive picture of your cortisol pattern throughout the day.
Blood Testing
Blood tests can measure both total cortisol and free cortisol levels. While blood testing is widely available and covered by most insurance plans, it only provides a snapshot of cortisol at the time of collection and can be affected by the stress of the blood draw itself.
For comprehensive health monitoring that includes cortisol alongside other important biomarkers, regular blood testing can provide valuable insights into your overall hormonal and metabolic health.
Urine Testing
24-hour urine cortisol testing measures the total amount of cortisol your body produces over a full day. This method is particularly useful for diagnosing Cushing's syndrome but can be inconvenient due to the need to collect all urine over 24 hours.
When to See a Healthcare Provider
You should consider consulting with a healthcare provider if you experience multiple symptoms of high cortisol, especially if they're affecting your quality of life or persisting despite lifestyle changes. Seek medical attention promptly if you have:
- Rapid, unexplained weight gain
- Severe mood changes or depression
- High blood pressure or blood sugar
- Muscle weakness that interferes with daily activities
- Frequent infections or slow healing
- Significant changes in your menstrual cycle
If you already have existing blood test results, you can upload them for a comprehensive analysis to better understand your cortisol levels and overall health status.

Natural Ways to Support Healthy Cortisol Levels
While medical treatment may be necessary for severe cases, several lifestyle strategies can help support healthy cortisol levels:
Stress Management Techniques
- Regular meditation or mindfulness practices
- Deep breathing exercises
- Yoga or gentle stretching
- Progressive muscle relaxation
- Spending time in nature
Sleep Optimization
- Maintaining a consistent sleep schedule
- Creating a relaxing bedtime routine
- Limiting screen time before bed
- Keeping your bedroom cool and dark
- Avoiding caffeine late in the day
Dietary Approaches
- Eating regular, balanced meals to stabilize blood sugar
- Limiting processed foods and added sugars
- Including omega-3 rich foods like fatty fish
- Consuming adequate protein at each meal
- Staying well-hydrated throughout the day
Taking Control of Your Cortisol Health
Recognizing the signs of high cortisol is the first step toward restoring balance and improving your overall health. While elevated cortisol can cause significant symptoms, the good news is that with proper testing, lifestyle modifications, and medical support when needed, most people can successfully manage their cortisol levels.
Remember that cortisol imbalances don't happen overnight, and neither does recovery. Be patient with yourself as you implement changes and work with healthcare providers to address any underlying causes. Regular monitoring through appropriate testing can help track your progress and ensure that your interventions are working effectively.
If you're experiencing symptoms that suggest high cortisol, don't wait to take action. Early intervention can prevent more serious health complications and help you regain the energy, mood stability, and overall well-being that elevated cortisol may have taken away.
