How to tell if your hormone levels are off?
Short answer: Common signs include unexplained weight change, persistent fatigue, mood swings, irregular menstrual cycles or changes in libido, and hair or skin changes. These symptoms can point to imbalances in thyroid, sex, adrenal, or metabolic hormones but require clinical testing for confirmation.
Explanation
Hormones regulate metabolism, reproduction, stress response and energy. Thyroid hormone problems often cause weight change, cold/heat intolerance, hair thinning, constipation or palpitations. Sex hormone imbalances (estrogen, progesterone, testosterone) cause irregular or absent periods, reduced libido, hot flashes, acne or fertility issues. Cortisol/adrenal dysfunction can cause fatigue, sleep disturbance, blood pressure or blood sugar changes and central weight gain. Insulin resistance shows as increased hunger, weight gain and elevated blood glucose. Because many conditions share symptoms, definitive diagnosis relies on targeted history, physical exam and laboratory tests (eg, TSH/free T4, estradiol/progesterone/testosterone, FSH/LH, fasting glucose or HbA1c, cortisol, prolactin). Abnormal results should be interpreted by a clinician in the context of symptoms, medications and timing (for menstrual-cycle–dependent tests).
Tips
- Keep a symptom and cycle log (sleep, mood, weight, periods) for several weeks before testing.
- See a primary care physician or endocrinologist for targeted evaluation rather than self-diagnosing.
- Request baseline labs: TSH/free T4, fasting glucose or HbA1c, lipid panel, and relevant sex hormones; add cortisol or prolactin if indicated.
- Review current medications, supplements, recent illnesses and stressors with your clinician.
- Follow up on abnormal results and ask about treatment options and lifestyle interventions (diet, sleep, exercise).
