Understanding DHEA and its function
Dehydroepiandrosterone (DHEA) is a steroid hormone produced by the adrenal glands, with smaller amounts made in the ovaries and testes. It serves as a precursor to androgens (male sex hormones) and estrogens (female sex hormones). Natural DHEA levels peak in your early 20s and decline gradually with age.
Because of this natural decline, DHEA supplements are marketed for various purposes, including anti-aging and boosting athletic performance. However, these over-the-counter supplements are not regulated by the FDA, and there is limited scientific evidence to support many of their claimed benefits. Taking too much DHEA can disrupt the body's delicate hormonal balance, leading to a range of mild to severe symptoms.
Symptoms of too much DHEA in women
For women, excess DHEA can lead to a state of hyperandrogenism (excess male hormones), causing a number of noticeable and often distressing symptoms.
-
Skin and hair changes
- Acne: Oily skin and severe breakouts, especially on the face, chest, and back, are common.
- Hirsutism: The growth of excessive facial and body hair in a male-like pattern is a classic sign.
- Hair loss: Women may experience male-pattern baldness, with hair thinning at the top of the head.
-
Menstrual cycle irregularities
- Amenorrhea: Missed or irregular menstrual periods are frequent, and can even lead to sterility.
-
Voice and physical changes
- Deepening of the voice: Increased androgens can cause the vocal cords to lengthen, resulting in a deeper voice.
- Increased muscle mass: Women may notice an increase in muscularity and changes in body composition.
- Clitoral enlargement: In severe cases, high androgen levels can lead to enlargement of the clitoris.
-
Other symptoms
- Breast tenderness: Pain or tenderness in the breasts can occur due to hormonal shifts.
Symptoms of too much DHEA in men
Men have naturally higher levels of androgens, so some symptoms of excess DHEA may be less obvious. However, excessive amounts can still cause problematic side effects, often due to the conversion of DHEA into estrogen.
-
Physical symptoms
- Gynecomastia: The development or enlargement of breast tissue is a key symptom of excess estrogen.
- Testicular shrinkage: Reduced sperm production and testicular atrophy can occur.
- Acne: As with women, oily skin and acne can be a side effect.
- Hair loss: Male-pattern baldness can be exacerbated by high androgen levels.
-
Metabolic and mood changes
- Mood swings: Increased irritability, mood swings, and aggression, sometimes called "roid rage," are possible.
- Fatigue: Paradoxically, hormone imbalances can sometimes lead to feelings of fatigue and low energy.
Common symptoms for both sexes
Some side effects of high DHEA levels are non-gender-specific and can impact anyone taking too much of the supplement.
-
Cardiovascular and metabolic effects
- High blood pressure: Excessive DHEA can elevate blood pressure.
- Lower HDL cholesterol: It may decrease levels of "good" HDL cholesterol, increasing cardiovascular risk.
- Insulin resistance: High DHEA is associated with insulin resistance, which can contribute to weight gain and increase the risk of type 2 diabetes.
-
Psychological and neurological effects
- Mood changes: Irritability, hostility, and mood swings are frequently reported side effects.
- Insomnia: Difficulty sleeping or maintaining a regular sleep pattern can occur.
-
Liver problems: High doses, especially over a prolonged period, can be toxic to the liver and may cause dysfunction.
Comparison of high DHEA symptoms in women vs. men
| Feature | Symptoms in Women | Symptoms in Men |
|---|---|---|
| Hirsutism | Common (facial/body hair) | Less common, but can include oily skin and acne |
| Voice | Deepening of the voice | Typically not affected, or less noticeable |
| Breast changes | Tenderness or pain | Gynecomastia (breast enlargement) |
| Hair loss | Male-pattern baldness | Exacerbation of male-pattern baldness |
| Menstrual cycle | Irregularities or amenorrhea | No effect; can cause reduced sperm production |
| Fertility | Potential infertility | Reduced sperm production; testicular shrinkage |
| Muscularity | Increased muscle mass | Can increase aggression (psychological) |
| Cholesterol | Lower HDL levels | Lower HDL levels |
Potential causes of excessively high DHEA levels
Elevated DHEA levels are not always caused by supplementation. Several underlying medical conditions can be the root cause and require professional diagnosis and treatment.
- Adrenal tumors: Benign or malignant tumors on the adrenal glands can overproduce DHEA.
- Congenital Adrenal Hyperplasia (CAH): This is a genetic disorder that affects the adrenal glands, leading to an overproduction of male hormones.
- Polycystic Ovary Syndrome (PCOS): A common endocrine disorder in women of reproductive age, PCOS is often associated with high androgen levels, including DHEA.
- Over-supplementation: Taking excessive doses of DHEA supplements is a direct and common cause of high levels.
- Medication interactions: Certain medications can alter DHEA levels, so it is important to disclose all medications to your doctor.
What to do if you suspect too much DHEA
If you are experiencing any of these symptoms, it is essential to consult a healthcare provider. The process for diagnosis and treatment typically involves these steps:
- Cease supplementation: If you are taking DHEA supplements, stop immediately and inform your doctor.
- Get tested: A blood test, usually for DHEA-sulfate (DHEA-S), is required to determine your hormone levels.
- Investigate the root cause: Your doctor will need to run tests to identify the underlying reason for your elevated DHEA, whether it is supplementation, an adrenal issue, or another condition.
- Follow a treatment plan: Based on the diagnosis, treatment may involve stopping the supplement, using targeted medications to balance hormones, or addressing an underlying condition like PCOS.
- Monitor progress: Regular follow-up appointments and blood tests will be necessary to ensure your DHEA levels return to a healthy range.
Conclusion
Understanding what are the symptoms of too much DHEA is crucial for anyone taking, or considering taking, this unregulated supplement. Excessively high levels can lead to a wide array of physical, hormonal, and psychological side effects that vary between men and women. Conditions such as PCOS, adrenal tumors, and over-supplementation are common causes. Given the potential health risks, including serious issues like liver toxicity and increased cancer risk, it is vital to consult a healthcare professional if you suspect elevated DHEA levels. Self-diagnosing and self-treating with unregulated supplements is dangerous and can lead to serious complications. For the safest approach, discuss all hormone-related concerns with a doctor to get a proper diagnosis and an appropriate, professionally monitored treatment plan.
