Lowering elevated DHEA levels typically involves identifying the underlying cause, since DHEA is produced almost exclusively by the adrenal glands and rises in response to specific conditions rather than on its own. The approach depends on whether the elevation is driven by a hormonal disorder, insulin resistance, or chronic stress, and treatment often combines medication with lifestyle changes over several months.
Why Your DHEA Might Be High
DHEA and its longer-lasting form, DHEA-S, are adrenal hormones regulated by the same signaling pathway that controls cortisol. When something pushes that pathway into overdrive, DHEA rises along with it. The most common reasons for elevated levels fall into a few categories.
Polycystic ovary syndrome (PCOS) is one of the most frequent causes in women of reproductive age. In PCOS, both the ovaries and adrenal glands can overproduce androgens, and elevated DHEA-S is one of the hallmark lab findings. Congenital adrenal hyperplasia, a genetic condition where the adrenal glands can’t produce cortisol efficiently, also causes significantly increased DHEA and DHEA-S because the glands compensate by overproducing other hormones. Premature adrenarche, where children develop early signs of puberty-related hormone changes, is another recognized cause.
Very high DHEA-S levels raise concern for adrenal tumors with autonomous hormone production. These tumors produce DHEA independently of normal hormonal signals, and the resulting levels tend to be dramatically elevated compared to other causes. If your DHEA-S is far above the expected range for your age, your doctor will likely order imaging to rule this out.
DHEA-S vs. DHEA: What Your Lab Results Mean
Most blood tests measure DHEA-S rather than DHEA itself, and there’s a practical reason for this. DHEA has a short half-life of only one to three hours, so its levels fluctuate throughout the day. DHEA-S, on the other hand, has a half-life of around 20 hours, which keeps it relatively stable from morning to evening. That stability makes DHEA-S a more reliable snapshot of what your adrenal glands are actually doing.
Normal DHEA-S levels vary significantly by age and sex. Levels peak in the late teens for women and in the twenties for men, then decline steadily with age. Men consistently have higher levels than women across all age groups. A number that looks elevated for a 55-year-old woman might be perfectly normal for a 25-year-old man, so any interpretation needs to account for your specific demographics. Women also sometimes see a slight bump in DHEA-S levels during their mid-thirties to mid-forties before the long-term decline resumes.
Medications That Lower DHEA
For women with PCOS or other androgen-excess conditions, two medications are commonly used, each working through a different mechanism.
Spironolactone has been used to treat excess androgens for over two decades. It works primarily by blocking androgen receptors, preventing DHEA and testosterone from exerting their effects on tissues. It also modestly reduces androgen production itself. In studies of women with PCOS, spironolactone significantly decreased DHEA-S levels. Its main benefit for most patients is reducing symptoms like excess hair growth and acne, with the hormonal reduction as a secondary effect.
Metformin takes a different approach. Originally developed for insulin resistance, it improves how the body handles glucose and reduces insulin levels. Since high insulin stimulates androgen production in the ovaries, bringing insulin down can lower DHEA and testosterone indirectly. Metformin has also been shown to directly inhibit androgen production in ovarian cells through an insulin-independent mechanism, giving it a dual path to reducing androgen levels.
For congenital adrenal hyperplasia, low-dose corticosteroids are the standard treatment. By supplying the cortisol the adrenal glands can’t make efficiently, these medications reduce the upstream signaling that drives DHEA overproduction.
How Long It Takes to See Results
Hormonal changes don’t happen overnight. Most treatment protocols for elevated DHEA run for at least three to six months before significant, sustained shifts appear on blood work. Your doctor will likely recheck your levels at the three-month mark to assess whether the current approach is working. If you’re being treated for PCOS with spironolactone or metformin, visible improvements in symptoms like hair growth or acne often lag even further behind the lab changes, since hair follicles operate on their own cycle.
Expect ongoing monitoring rather than a single treatment course. DHEA-S levels need to be tracked over time to confirm they’re trending in the right direction and to adjust medication doses if needed.
Lifestyle Changes That Influence DHEA
Because DHEA is tied to the body’s stress-response system, lifestyle factors that affect cortisol also influence DHEA production. Chronic stress keeps the adrenal signaling pathway activated, which can sustain elevated DHEA levels even when other factors are under control.
Sleep plays a central role. The adrenal signaling system follows a circadian rhythm, and disrupted or insufficient sleep can keep adrenal output elevated. Prioritizing consistent sleep timing and adequate duration (seven to nine hours for most adults) helps normalize the hormonal patterns that regulate DHEA production.
Stress management techniques that lower cortisol output, such as meditation, deep breathing exercises, and regular physical activity, can help bring down overall adrenal hormone levels. The key is consistency over weeks and months rather than occasional efforts.
The Role of Exercise
Exercise has a nuanced relationship with DHEA. Moderate-intensity exercise performed regularly over weeks actually increases DHEA levels, which is beneficial for older adults whose levels have declined with age. A 10-week program of moderate-intensity exercise (about 60% of maximum heart rate) in adults averaging 74 years old significantly raised DHEA from baseline, with increases visible by week five.
This matters if you’re trying to lower DHEA: intense or prolonged exercise isn’t a direct tool for reducing it. However, regular physical activity helps lower DHEA indirectly by improving insulin sensitivity, reducing body fat, and lowering chronic stress hormones. For women with PCOS, exercise is particularly valuable because it addresses the insulin resistance that drives androgen overproduction. The net effect on DHEA depends on your starting point and the underlying cause of elevation.
Dietary Factors and Insulin
If insulin resistance is contributing to your elevated DHEA, dietary changes that improve insulin sensitivity can make a meaningful difference. Reducing refined carbohydrates and added sugars helps lower the insulin spikes that stimulate androgen production. Increasing fiber, lean protein, and healthy fats slows glucose absorption and keeps insulin levels more stable throughout the day.
Maintaining a healthy weight is one of the most effective non-medication strategies. Excess body fat, particularly around the midsection, worsens insulin resistance and keeps the cycle of high insulin and high androgens going. Even modest weight loss of 5 to 10 percent of body weight has been shown to improve hormonal profiles in women with PCOS.
Supplements to Avoid
DHEA is sold over the counter as a supplement, and it’s effective at raising levels. A daily 100 mg dose restored DHEA-S to young-adult levels in older men and women within six months. If you’re trying to lower your DHEA, check any supplements you’re currently taking. DHEA is sometimes included in “anti-aging” or “adrenal support” formulas, and stopping these products is an obvious first step. Some herbal supplements marketed for energy or hormonal balance may also influence adrenal function in ways that aren’t well characterized, so review your full supplement list with a healthcare provider.
