Adrenal gland problems in women most commonly show up as persistent fatigue, unexplained weight changes, menstrual irregularities, and skin or hair changes that don’t respond to typical treatments. Because the adrenal glands produce cortisol, aldosterone, and androgens, the specific signs depend on whether hormone levels are too low, too high, or imbalanced. Women are disproportionately affected: female rates of adrenal disorders are two to five times higher than male rates, depending on the condition.
Signs of Low Cortisol (Adrenal Insufficiency)
Adrenal insufficiency, including Addison’s disease, means your adrenal glands aren’t producing enough cortisol and sometimes not enough aldosterone either. The hallmark symptoms are chronic fatigue that doesn’t improve with rest, muscle weakness, appetite loss, and gradual weight loss. Many women also experience nausea, recurring abdominal pain, and diarrhea. These symptoms tend to develop slowly over weeks or months, which makes them easy to dismiss as stress or poor sleep.
Low aldosterone specifically causes salt cravings and a drop in blood pressure when you stand up, leading to dizziness or even fainting. Irritability, depression, and low blood sugar episodes are also common. Women with adrenal insufficiency frequently report loss of libido, thinning of pubic and underarm hair, and irregular or absent periods.
One of the most distinctive visible signs is skin darkening. In Addison’s disease, excess signaling from the pituitary gland triggers increased pigmentation, especially in areas exposed to sun, friction zones like the groin and underarms, the creases of your palms, your knuckles, and any recently healed scars. Brown patches on the gums, inner cheeks, or lips can sometimes be the very first sign, appearing before other symptoms become obvious.
Signs of Excess Cortisol (Cushing’s Syndrome)
When the adrenal glands produce too much cortisol, the result is Cushing’s syndrome. Women are roughly five times more likely than men to develop this condition. The physical changes are often dramatic: weight gain concentrated in the midsection and upper back (sometimes forming a visible fatty hump between the shoulders), a rounded “moon face,” and progressively thinner arms and legs. Pink or purple stretch marks may appear on the stomach, hips, thighs, breasts, and underarms. The skin bruises easily and heals slowly.
Menstrual disruption is one of the most reliable early clues. About 80% of women with Cushing’s syndrome experience menstrual irregularities. In one study of 45 women with the condition, only 20% had normal cycles. The rest had infrequent periods, no periods at all, or unusually frequent bleeding. High cortisol also commonly causes acne, facial hair growth, and thinning hair on the scalp.
Signs of Excess Adrenal Androgens
The adrenal glands produce androgens (sometimes called “male hormones,” though women need them too). When levels climb too high, the three classic signs in women are hirsutism (coarse hair growing on the face, chest, or back), persistent acne that doesn’t clear with standard skincare, and thinning hair on the scalp in a pattern similar to male baldness. These symptoms overlap significantly with polycystic ovary syndrome (PCOS), which is why testing adrenal hormone levels matters for getting the right diagnosis.
One adrenal-specific cause of androgen excess is non-classic congenital adrenal hyperplasia (CAH), a genetic condition that may not become apparent until adolescence or adulthood. Women with non-classic CAH often develop facial and body hair, a deeper voice, irregular periods or no periods, and difficulty getting pregnant. Some girls with the condition show early pubic hair growth well before the typical age of puberty.
Episodic Symptoms From Adrenal Tumors
Pheochromocytoma is a rare tumor of the adrenal gland that produces surges of adrenaline and related hormones. The defining feature is that symptoms come in sudden episodes rather than being constant. The classic triad is a pounding headache, heavy sweating, and rapid heartbeat, often accompanied by a spike in blood pressure. These episodes can last minutes to hours and may be triggered by physical exertion, stress, or certain foods. Between episodes, you may feel completely normal, which can make the condition puzzling to identify.
Mood and Mental Health Changes
Adrenal hormone imbalances don’t just affect the body. Low cortisol is linked to irritability, depression, and a general sense of mental fog. High cortisol can cause anxiety, mood swings, difficulty sleeping, and in some cases more severe psychiatric symptoms. These mental health effects often precede or accompany the physical signs, and they’re frequently attributed to other causes before adrenal testing is considered.
How Adrenal Problems Are Identified
Diagnosis typically starts with blood tests measuring cortisol levels. A morning cortisol below 5 micrograms per deciliter strongly suggests adrenal insufficiency, while values between 5 and 10 fall into a gray zone that requires further testing. For suspected Cushing’s syndrome, a screening test checks whether your body can properly suppress cortisol production overnight; healthy individuals will show morning cortisol at or below 1.8 micrograms per deciliter after the test.
If excess androgens are suspected, your doctor may check DHEA-S, a hormone produced almost exclusively by the adrenal glands. Normal ranges for women shift with age: a woman in her 20s typically falls between 45 and 320 micrograms per deciliter, while a woman over 60 would normally be below 145. Values well above the expected range for your age point toward an adrenal source of androgen excess rather than an ovarian one.
Adrenal Insufficiency vs. “Adrenal Fatigue”
The term “adrenal fatigue” is widely used online to describe a state where chronic stress supposedly wears out the adrenal glands, causing tiredness, brain fog, and cravings. The Endocrine Society has stated clearly that the adrenal glands do not lose function because of mental or physical stress. True adrenal insufficiency is a rare, measurable condition diagnosed through standardized hormone testing. If you’re experiencing persistent fatigue and other symptoms on this list, the productive next step is hormone testing rather than self-treating for a condition that lacks a medical basis.
