TSH (Thyroid Stimulating Hormone) testing measures pituitary TSH to evaluate whether a woman's thyroid is underactive (hypothyroid) or overactive (hyperthyroid). Abnormal TSH levels are a leading cause of fatigue, unexplained weight changes, menstrual irregularities, infertility, hair loss, and mood swings in women.
Next steps depend on whether your TSH is low, normal, or high, and may include free T4 and T3 testing, thyroid antibody panels, ultrasound imaging, endocrinology referral, and targeted treatment such as levothyroxine for hypothyroidism or anti-thyroid medications for hyperthyroidism. See below for details on interpreting your results.
Because thyroid symptoms overlap with many other conditions—including perimenopause, anemia, and depression—self-diagnosis is unreliable. Before assuming TSH is the answer, take a free, instant, online symptom check to clarify what's driving how you feel and identify the right tests and next steps for your specific situation.
