Are Your Adrenal Glands Causing You Problems?

People talk of having overtaxed adrenals, but is that a real condition, and what even are the adrenals? The adrenal glands are two small, triangular-shaped glands located on top of your kidneys. Despite their size, they play a huge role in hormone production, regulating your response to stress, metabolism, blood pressure, immune function, and more.

What Do the Adrenal Glands Do?

Each adrenal gland has two parts, each with distinct functions:

1. Adrenal Cortex (outer layer)

Produces essential steroid hormones, including:

• Cortisol – regulates stress response, blood sugar, and metabolism
• Aldosterone – manages blood pressure and salt/water balance
• Androgens – small amounts of sex hormones (e.g., testosterone, estrogen)

2. Adrenal Medulla (inner part)

Produces catecholamines, including:

• Adrenaline (epinephrine) – fight-or-flight hormone
• Noradrenaline (norepinephrine) – increases heart rate and blood pressure

Together, these hormones help your body adapt to chronic stress and immediate threats while regulating everyday processes like energy production and hydration.

Common Adrenal Gland Disorders to Watch For

1. Adrenal Insufficiency (Addison’s Disease)

• The adrenal glands don’t produce enough cortisol (and sometimes aldosterone)
• Symptoms: Fatigue, weight loss, low blood pressure, salt cravings, skin darkening
• Often autoimmune, but can result from infection or medication

2. Cushing’s Syndrome

• Caused by too much cortisol, often from long-term steroid use or adrenal tumors
• Symptoms: Rapid weight gain (especially in the trunk and face), muscle weakness, easy bruising, high blood pressure, mood swings

3. Adrenal Fatigue (not officially recognized in mainstream medicine)

• A controversial concept suggesting the adrenal glands “burn out” due to chronic stress
• Symptoms (anecdotally reported): Brain fog, exhaustion, sleep issues, low libido
• While not a medically accepted diagnosis, these symptoms could reflect real issues like HPA axis dysfunction or subclinical adrenal insufficiency

4. Congenital Adrenal Hyperplasia (CAH)

• A genetic condition affecting cortisol and/or aldosterone production
• Can lead to abnormal hormone levels and developmental issues (e.g., early puberty or ambiguous genitalia)

5. Pheochromocytoma

• A rare tumor in the adrenal medulla causing overproduction of adrenaline
• Symptoms: Sudden high blood pressure, pounding headaches, rapid heart rate, sweating, anxiety

6. Hyperaldosteronism (Conn’s Syndrome)

• The adrenal glands produce too much aldosterone
• Symptoms: High blood pressure, low potassium, muscle cramps, fatigue

When Should You Get Checked?

See a doctor or endocrinologist if you experience:

• Unexplained fatigue or weight changes
• Salt cravings or very low blood pressure
• Fluctuating heart rate or chronic anxiety
• Hormonal imbalances (especially if accompanied by skin or mood changes)

Blood tests, such as ACTH stimulation, cortisol levels, aldosterone/renin ratio, or 24-hour urine hormone tests, can help assess adrenal function.

Your adrenal glands may be small, but their impact on your physical and emotional health is significant. They control how you respond to stress, regulate critical hormones, and influence everything from energy to immunity. While adrenal issues are relatively rare, staying aware of their symptoms, especially in the context of stress, fatigue, and hormone imbalances, can help you catch potential problems early.  The more you know about the different systems of the body and their functions, the more empowered you can be about your healthcare.
