Thyroid and Hormone Balance: The Overlooked Connection
Fatigue, brain fog, mood changes, and weight shifts can be perimenopause, andropause, or thyroid — and often more than one at once.
Overlapping symptoms
Hypothyroidism and menopause both cause fatigue, weight gain, mood changes, and cognitive slowing. Hyperthyroidism can mimic vasomotor symptoms with sweating, palpitations, and sleep disturbance. TSH belongs in every hormonal workup, regardless of the suspected axis.
Interactions during hormone therapy
Oral estrogen raises thyroxine-binding globulin, which can lower free T4 and raise the required levothyroxine dose. Patients on thyroid replacement starting oral estrogen should have TSH rechecked at 6–12 weeks.
