In women, imbalance often shows up around cycles and life stages: heavy or irregular periods, PMS that’s getting worse, perimenopause sleep and mood changes, or the higher androgens and insulin resistance of PCOS. A slow thyroid can sit underneath any of these.
In men, it more often looks like fading energy, drive, and strength, more belly fat, and lower libido — frequently tied to low testosterone, insulin resistance, poor sleep, or stress. In both, the answer starts with testing the whole system rather than one hormone at a time.
