DHEA, or dehydroepiandrosterone, is an important hormone that is produced naturally in the body. DHEA is considered a "prohormone" because it can be converted into other hormones in the body like testosterone and estrogen.
Some key points about DHEA:
- DHEA levels peak around age 25 and then decline with age. By age 75-80, DHEA levels are only about 20% of what they were at their peak.
- DHEA is made from cholesterol mainly in the adrenal glands near the kidneys. It's also produced in smaller amounts in the testes, ovaries, and brain.
- DHEA helps produce other important hormones and plays a role in important processes like bone growth, libido, and fat metabolism.
- DHEA levels that are too high or too low can cause health issues. That's why there's a normal range.
Now, you may be wondering: What causes
low DHEA levels? There are a few potential culprits:
- Aging - As mentioned earlier, DHEA declines naturally as we get older.
- Adrenal insufficiency - The adrenal glands produce less DHEA.
- Stress - Chronic stress takes a toll on adrenal gland function.
Some
signs and symptoms of low DHEA:
- Low libido
- Loss of muscle mass
- Decreased bone density
- Depression
- Fatigue
If lab tests confirm abnormally low DHEA for your age, your doctor may recommend DHEA
supplements to bring your levels back to an optimal range. Start with the smallest dose possible and have your levels retested in a few months. Too much DHEA from supplements can cause side effects like oily skin, fatigue, mood changes, and uneven heartbeats.
The takeaway? DHEA is a vital hormone that starts high in early adulthood and declines with age. Low levels may cause symptoms that can be bothersome.
Blood tests can determine if your DHEA is low. Supplements may help, but don't overdo it. Staying active and managing stress can help keep DHEA at healthy levels as you get older too.
