The Key Hormones: What They Are, What They Do and What Happens When They’re Unbalanced Part I

Estrogen

WHAT IT DOES: Responsible for female characteristics and sexual functions. Also present in men, but at much lower levels.

WHEN UNBALANCED: Low estrogen levels are the primary culprit in hot flashes, night sweating, dryness, loss of sex drive, and mood swings associated with menopause. Low levels can also increase the risk of heart disease, stroke, and bone fractures.

Progesterone

WHAT IT DOES: Important for ovulation and menstruation.

WHEN UNBALANCED: Low progesterone levels can lead to insomnia, foggy thinking, mood changes, joint and muscle pain, and weight gain.

Testosterone

WHAT IT DOES: Responsible for male characteristics and sex drive. Also found in low levels in women.

WHEN UNBALANCED: Lower sex drive, decreased muscle mass, increased risk of heart disease. Lethargy and weight gain can also accompany low levels.
