Everyone seems to be talking about cortisol lately.
From social media videos about “high cortisol” to supplements claiming to lower stress hormones, it’s easy to wonder whether cortisol is the reason you’re feeling tired, gaining weight, or struggling to lose weight.
The reality is that cortisol plays an essential role in your health, and true cortisol disorders are much less common than many online posts suggest.
At Texas Diabetes & Endocrinology, our board-certified endocrinologists specialize in diagnosing hormone disorders and identifying the underlying cause of symptoms. Rather than focusing on a single hormone or lab result, we evaluate the complete picture to determine whether cortisol, or another condition, is contributing to your symptoms.
What Does Cortisol Do?
Cortisol is often called the body’s “stress hormone,” but it does much more than help you respond to stressful situations.
Produced by the adrenal glands, cortisol helps regulate:
- Metabolism
- Blood sugar
- Blood pressure
- Energy production
- Immune function
- Your body’s response to physical and emotional stress
Your body naturally produces more cortisol in the morning to help you wake up, with levels gradually declining throughout the day. This daily rhythm is one reason cortisol testing requires careful timing and interpretation.
Do I Need My Cortisol Levels Tested?
Not necessarily.
Many symptoms commonly associated with “high cortisol”—such as fatigue, weight gain, trouble sleeping, and mood changes—can also be caused by a variety of other conditions.
These may include:
- Thyroid disorders
- Insulin resistance or diabetes
- Menopause
- Poor sleep
- Chronic stress
- Certain medications
- Other hormone imbalances
Because these symptoms overlap with many conditions, endocrinologists first determine whether cortisol is likely to be the cause before recommending specialized testing.
How Do Endocrinologists Diagnose Cortisol Disorders?
Diagnosing a cortisol disorder isn’t as simple as checking one lab value.
Endocrinologists are trained to recognize patterns in your symptoms, medical history, physical exam, medications, and laboratory results that may point toward, or away from, a true cortisol disorder.
Your evaluation may include:
- A comprehensive medical history
- Review of medications, including steroid use
- Physical examination
- Blood, saliva, or 24-hour urine cortisol testing when appropriate
- Additional hormone testing
- Imaging studies, if needed
Our goal is to identify the underlying cause of your symptoms so you receive the right diagnosis and treatment.
When Should You See an Endocrinologist?
You may benefit from seeing an endocrinologist for cortisol concerns if you have:
- Persistent fatigue that doesn’t improve
- Unexplained rapid weight gain or weight loss
- Significantly high blood sugar levels
- A suspected adrenal or pituitary disorder
- Blood pressure changes along with other hormone-related symptoms
- Osteoporosis or breaking of bones
Our endocrinologists specialize in diagnosing and treating disorders affecting the adrenal glands, pituitary gland, thyroid, and other hormone-producing organs.
Cortisol Is Just One Piece of Your Metabolic Health
Cortisol is only one part of your body’s complex endocrine system.
At Texas Diabetes & Endocrinology, our board-certified endocrinologists evaluate your hormones within the context of your overall metabolic health, helping identify the underlying cause and develop a personalized treatment plan.
