When insulin sensitivity decreases, it sends a signal to your ovaries to produce more androgens. This creates hormone imbalances that affect everything from cycle regularity to weight distribution, skin quality, and metabolism. Blood tests reveal both the hormone pattern and the underlying insulin issue driving it.
LH (Luteinizing Hormone) and FSH (Follicle-Stimulating Hormone) are produced by your pituitary gland to regulate your menstrual cycle. Normally, they work in balanced coordination. But when insulin resistance develops, it disrupts this balance. LH rises while FSH stays relatively normal, creating an elevated LH:FSH ratio. This imbalance triggers your ovaries to produce excess testosterone and DHEA-S instead of progressing through normal ovulation.
When the LH:FSH ratio climbs, it reveals ovarian signaling has gone chaotic. Your ovaries are receiving conflicting messages. Meanwhile, elevated insulin and low SHBG (sex hormone binding globulin) mean more free testosterone circulates in your blood. This drives acne, excess hair growth, and makes weight loss harder. Your period shows up unpredictably or not at all because ovulation isn't happening consistently.
Key insight: Irregular cycles aren't just a hormone problem. They're often driven by insulin resistance creating hormone chaos. The weight gain, acne, and irregular periods are all connected through the same metabolic disruption.
Bottom line: Cycle irregularity reveals how insulin sensitivity, ovarian hormone production, and metabolic balance interact. At Lucis, we measure testosterone, DHEA-S, LH, LH:FSH ratio, SHBG, and insulin. Not just whether your hormones are abnormal, but whether the pattern reveals the root cause driving your symptoms.
