In women, too much testosterone can promote insulin resistance and visceral fat.
That’s why androgen excess is the primary driver of weight gain with polycystic ovary syndrome (PCOS), some types of birth control, and perimenopause.
PCOS
PCOS is defined as a set of symptoms including androgen excess and anovulatory cycles. In simplest terms, PCOS is the condition of androgen excess when all other causes of androgen excess have been ruled out. It’s an umbrella diagnosis which can be caused by different underlying drivers or functional types. The four functional types of PCOS are insulin-resistant PCOS, post-pill PCOS, inflammatory PCOS, and adrenal PCOS.
How Science Got It Wrong About Progesterone
Progesterone has been both ignored and wrongly blamed for side effects it does not cause. How did that happen?
For one thing, progesterone was discovered shortly after estrogen. Thus missing the opportunity to be part of the tidy hormone dichotomy of “testosterone for men and estrogen for women.” Also, progesterone could not (at first) be made into an oral medication, so was replaced by progestins.
Decoding Hypoglycemia: Is It Insulin Resistance or Dysautonomia?
Is your low blood sugar a symptom of insulin resistance or mild dysfunction of the autonomic nervous system?
In episode 16 of my podcast, I return to the topic of hypoglycemia to discuss the difference between insulin resistance and dysautonomia, why unstable blood sugar does not automatically mean insulin resistance, and my concerns about continuous glucose monitoring.
The Secret Powers of Ovulation (It’s Not Just to Make a Baby)
The ovarian hormones estradiol and progesterone are beneficial for general health. That means natural ovulatory menstrual cycles are beneficial because ovulation is how women make those hormones.
