Adrenal gland problems in men most commonly show up as persistent fatigue, unexplained weight changes, muscle weakness, and sexual dysfunction. Because the adrenal glands produce cortisol, adrenaline, and hormones that influence blood pressure and sex drive, problems with these glands can affect nearly every system in the body. The specific signs depend on whether your adrenals are producing too little, too much, or the wrong balance of hormones.
Fatigue, Weight Loss, and Skin Changes
When the adrenal glands don’t produce enough cortisol, a condition called adrenal insufficiency, the most recognizable signs are chronic fatigue, muscle weakness, loss of appetite, weight loss, and abdominal pain. This isn’t ordinary tiredness. Men with adrenal insufficiency often describe an exhaustion that doesn’t improve with rest and gets worse over weeks or months.
One distinctive sign is skin darkening, especially in areas that wouldn’t normally tan. This darkening tends to appear on scars, skin folds, pressure points like the elbows, knees, and knuckles, the lips, and even inside the cheeks. It happens because the brain produces more of a signaling hormone trying to stimulate the failing adrenal glands, and that same hormone triggers pigment cells in the skin.
Sexual Dysfunction Is More Common Than Expected
Erectile dysfunction is one of the most underrecognized signs of adrenal problems in men. A study published in the journal Andrology found that 59% of men with adrenal insufficiency had sexual dysfunction, with erectile difficulties specifically affecting about 57% of participants. That rate is notably higher than in the general population. Among men under 40 with adrenal insufficiency, 30% experienced erectile dysfunction, rising to 74% in those over 40.
What makes this finding surprising is that the erectile problems didn’t clearly link to testosterone levels. Men with normal testosterone had similar rates of dysfunction as those with low testosterone. Instead, sexual function correlated most strongly with fatigue and overall quality of life, suggesting the condition’s drain on energy and well-being plays a bigger role than hormone levels alone. Reduced libido often accompanies the fatigue, though it’s easy to dismiss as stress or aging.
Weight Gain and Body Shape Changes
When the adrenals produce too much cortisol, the signs look very different from insufficiency. Excess cortisol, known as Cushing’s syndrome, causes a characteristic pattern of fat redistribution: weight gain concentrated in the face (creating a rounder appearance), the upper back (sometimes called a “buffalo hump”), and around the base of the neck, while the arms and legs stay thin or even lose muscle mass. Wide, purple stretch marks may appear on the abdomen, hips, and under the arms. The skin bruises easily and heals slowly.
Men with Cushing’s syndrome often notice that their muscles feel weaker despite not changing their activity level. This happens because excess cortisol breaks down muscle protein over time, particularly in the thighs and upper arms. The combination of central weight gain with thinning limbs is one of the clearest visual indicators.
Blood Pressure Spikes and Sudden Episodes
Some adrenal problems announce themselves through dramatic surges in blood pressure. A pheochromocytoma, a rare tumor in the inner part of the adrenal gland, releases bursts of adrenaline into the bloodstream. The classic triad of symptoms is high blood pressure, severe headaches, and excessive sweating without physical exertion. These episodes can come on suddenly and feel like a panic attack, with a racing heart and a sense of dread.
A separate condition called hyperaldosteronism, where the adrenals overproduce a hormone that controls sodium and potassium balance, also causes high blood pressure. But it tends to be persistent rather than episodic. Other signs include constant tiredness, muscle weakness, numbness, and headaches. Low potassium is a hallmark of this condition and can cause muscle cramps or an irregular heartbeat. Men with resistant high blood pressure that doesn’t respond well to standard treatment are sometimes found to have this as the underlying cause.
Mood, Concentration, and Mental Health
Adrenal problems can mimic psychiatric conditions closely enough to cause misdiagnosis for years. Depression, anxiety, poor concentration, sleep disturbances, and even psychosis have all been documented in people with undiagnosed adrenal insufficiency. One published case described a man whose long-standing low mood, poor concentration, disrupted sleep, and low energy had affected his education, work, and personal life for years before the adrenal problem was identified. Once treated, his mood and concentration improved substantially.
Brain fog and difficulty focusing are common complaints. These cognitive symptoms tend to track with cortisol levels: too little cortisol impairs the brain’s ability to manage energy and inflammation, while too much cortisol (as in Cushing’s syndrome) can cause irritability, anxiety, and difficulty with memory. In both cases, the mental health symptoms often improve once the underlying hormonal imbalance is corrected.
Signs That Are Easy to Overlook
Many adrenal symptoms overlap with conditions that are far more common, which is why they’re frequently missed. Fatigue gets attributed to poor sleep. Erectile dysfunction gets blamed on stress. Weight gain gets chalked up to diet. Mood changes get treated as depression. The key distinction is that adrenal problems typically produce clusters of symptoms rather than isolated ones, and those symptoms tend to worsen progressively.
Some genetic adrenal conditions don’t cause obvious symptoms in men at all. Non-classic congenital adrenal hyperplasia, a mild form of an inherited enzyme deficiency, often goes undetected in males. Affected men are generally asymptomatic and usually get diagnosed only after a female family member is identified with the condition. Occasionally, an adrenal growth found incidentally during imaging for another reason turns out to be related.
How Adrenal Problems Are Identified
A morning blood cortisol test is typically the starting point. Normal morning cortisol falls between 5 and 25 micrograms per deciliter, though values near either extreme may prompt further investigation depending on your symptoms. If adrenal insufficiency is suspected, a stimulation test may follow. During this test, you receive a small injection of a synthetic version of the brain hormone that normally tells your adrenals to produce cortisol, and blood samples are taken at 30 and 60 minutes to see how your glands respond. The entire process takes about an hour.
For suspected cortisol excess, urine and saliva tests collected at specific times of day help confirm whether cortisol production is abnormally high. Blood pressure problems may lead to testing aldosterone and potassium levels. Imaging scans of the adrenal glands are used when a tumor is suspected, particularly for pheochromocytoma.
