10 Hidden Signs of High Cortisol You’re Ignoring
Sarah, a busy professional, initially attributed her constant fatigue, weight gain around her middle, and frequent colds to work stress. However, it wasn’t until her doctor conducted hormone tests that she uncovered the underlying issue: dangerously high cortisol levels.
Cortisol, often referred to as the “stress hormone,” is a hormone that plays a crucial role in our body’s response to stress. However, many people are unaware that chronically elevated cortisol levels can have far-reaching and detrimental effects on our well-being, extending beyond mere feelings of overwhelm.
Recognizing the early signs of high cortisol, such as fatigue, weight gain, anxiety, and even digestive issues, can help you take proactive steps to manage it before it escalates.
While temporary spikes in cortisol are normal and even beneficial, prolonged elevation of cortisol levels for weeks or months can lead to the body sending distress signals that are often misinterpreted.
What Exactly Is Cortisol and Why Does It Matter?
Cortisol is a steroid hormone produced by your adrenal glands. In healthy amounts, it helps regulate blood sugar, reduces inflammation, and gives you energy to handle challenges. The problem starts when your cortisol levels remain consistently high due to chronic stress, certain medications, or underlying health conditions.
According to research published in the Journal of Clinical Medicine, prolonged cortisol elevation affects nearly every system in your body, from your immune function to your metabolism. Yet many people suffer for years without realizing their symptoms point to a hormonal imbalance rather than just “being stressed.”
10 Warning Signs of High Cortisol Levels
1: Physical Changes You Can See and Feel
Unexplained weight gain, particularly around the midsection, can be attributed to high cortisol levels. Cortisol triggers the body to store fat, especially in the abdomen and between the shoulder blades. This type of weight gain doesn’t respond well to conventional diet and exercise methods.
Purple or Pink Stretch Marks While regular stretch marks are usually white or silver, cortisol-related stretch marks appear purple or pink and often show up on your stomach, thighs, or arms without significant weight changes.
Easy Bruising and Slow Healing If you’re getting bruises from minor bumps or cuts that take forever to heal, elevated cortisol might be suppressing your body’s natural repair processes.
2: Energy and Sleep Disruptions
Feeling Wired at Night but Exhausted During the Day High cortisol disrupts your natural sleep-wake cycle. You might feel tired all day but find your mind racing when you try to sleep, creating a frustrating cycle of fatigue and insomnia.
Afternoon Energy Crashes That 3 PM slump might not be normal after all. Cortisol should naturally peak in the morning and gradually decline throughout the day. When this pattern gets disrupted, you experience dramatic energy fluctuations.
3: Immune System and Health Issues
Getting Sick More Often Than Usual Chronically high cortisol suppresses your immune system, making you more susceptible to colds, infections, and other illnesses. If you’re catching every bug that goes around, your cortisol levels might be to blame.
High Blood Sugar and Increased Cravings Cortisol raises blood glucose levels and can make you crave sugary or high-fat foods. Many people with elevated cortisol develop insulin resistance, which can progress to type 2 diabetes if left untreated.
Mood and Cognitive Changes
Anxiety That Feels Different from Regular Stress While stress causes temporary anxiety, cortisol-related anxiety often feels more persistent and intense. It might include physical symptoms like rapid heartbeat, sweating, or feeling “on edge” even in calm situations.
Memory Problems and Difficulty Concentrating High cortisol can actually shrink the hippocampus, the brain region responsible for memory and learning. If you’re having trouble remembering things or staying focused, elevated cortisol could be interfering with your cognitive function.
Mood Swings and Irritability Cortisol affects neurotransmitter production, leading to unpredictable mood changes. You might find yourself snapping at loved ones or feeling overwhelmed by situations that normally wouldn’t bother you.
When to See a Doctor About Cortisol Levels
According to the Mayo Clinic, if you experience several of these symptoms consistently for more than a few weeks, you should consider testing your cortisol levels.
Your doctor can order simple blood, urine, or saliva tests to measure your cortisol levels at various times of the day. Testing is particularly crucial if you have risk factors such as:
- Taking corticosteroid medications
- Chronic stress from work or personal life
- Family history of hormonal disorders
- Other symptoms like high blood pressure or osteoporosis
Natural Ways to Support Healthy Cortisol Levels
The positive news is that making lifestyle changes can have a significant impact on cortisol levels.
Prioritize sleep quality by aiming for 7-9 hours of consistent sleep. Even if you can’t alter your bedtime, maintaining a regular schedule helps regulate cortisol production.
Practicing stress management techniques such as meditation, deep breathing, or yoga has been proven to reduce cortisol levels in numerous studies.
Exercise Regularly (But Don’t Overdo It): Moderate exercise reduces cortisol, but intense training can actually increase it. Find the right balance for your body.
Eat a Balanced Diet: Focus on whole foods and limit processed sugar, which can cause cortisol spikes.
The Bottom Line
High cortisol levels are more common than many people realize, and the symptoms often masquerade as everyday stress or aging. But ignoring these signs can lead to serious health consequences, including diabetes, heart disease, and depression.
If you recognize several of these symptoms in yourself, don’t assume it’s just stress. A simple conversation with your healthcare provider could be the first step toward feeling like yourself again.
Frequently Asked Questions
Q: How quickly can cortisol levels return to normal?
With proper treatment and lifestyle changes, cortisol levels can start improving within a few weeks, though it may take several months to see full normalization depending on the underlying cause.
Q: Can high cortisol cause permanent damage?
While long-term elevation can lead to serious health issues, most cortisol-related problems are reversible with appropriate treatment and management.
Q: What’s the difference between cortisol from stress versus a medical condition?
Stress-related cortisol elevation usually improves when stressors are removed, while medical conditions like Cushing’s syndrome require specific treatment to normalize levels.
Q: Are cortisol supplements safe to take?
Never take cortisol supplements without medical supervision. Most people with high cortisol need to lower their levels, not raise them further.
Q: Can diet alone fix high cortisol levels?
Diet can help support healthy cortisol levels, but severe elevation often requires medical intervention combined with lifestyle changes.
Q: How accurate are at-home cortisol tests?
At-home saliva tests can be helpful for screening, but blood tests ordered by your doctor provide the most accurate diagnosis and monitoring.
