Dr Oz: Are Your Hormones Out of Whack?

The Clues
In the years preceding menopause, a woman may suffer from decreased testosterone as her ovaries and adrenal glands slow the production of sex hormones. This may explain why many women experience a drop in libido during this period of their lives. Excess testosterone, however, may be the result of a condition called polycystic ovary syndrome (PCOS); possible symptoms include irregular periods, male-pattern baldness, a deepening voice, and excess body hair.

What You Can Do
If you're concerned about low libido, try incorporating more zinc-rich foods—like oysters and sesame seeds—into your diet (zinc appears to be linked to an increase in testosterone levels), and ask your doctor about testosterone supplementation. To treat PCOS, your doctor might recommend taking birth control pills containing synthetic hormones that reduce the production of testosterone. It's also important to avoid refined sugars and other carbohydrates in your diet (insulin resistance is linked to a boost in testosterone production) and to eat more fiber (which counteracts blood sugar spikes and promotes the excretion of excess sugars from the body).
