Hormone imbalance: easy signs, tests you can ask for, and what to do next

Feeling off but not sure why? Hormones control sleep, mood, energy, weight, sex drive, and more. When they’re out of balance you may notice tiredness that rest doesn’t fix, sudden weight changes, mood swings, irregular periods, low libido, hair loss, or brain fog. Those symptoms sound vague because they are—so a clear plan helps you and your doctor find the cause faster.

Quick checklist: common causes and signs

Start with a short checklist: are you dealing with extreme tiredness, hot flashes, missed periods, erectile issues, or rapid weight gain? Thyroid problems often cause fatigue, cold intolerance, weight gain, and constipation. Estrogen imbalance shows up as irregular periods, hot flashes, and mood swings. Low testosterone can bring low energy, reduced libido, and muscle loss. Medications, stress, poor sleep, and certain supplements can also shift your hormones.

Write down when symptoms started, any recent meds or life changes, and how they affect daily life. This record makes tests and treatment choices clearer.

Tests to ask for and what they tell you

Tell your clinician you want basic hormone checks. Common tests include TSH, free T4 and free T3 for thyroid; estradiol, FSH, and LH for ovarian function; total and free testosterone for men and women; and sometimes cortisol or prolactin. Timing matters—test estradiol or progesterone based on your cycle, and check testosterone in the morning. Labs give you a starting point; your doctor will match results to your symptoms, not just numbers.

If results are unclear, ask about repeat tests, referral to an endocrinologist, or imaging for suspected issues like nodules or tumors. Don’t accept “normal” lab words if your symptoms persist—numbers can sit in the normal range while you still feel unwell.

Treatment depends on the cause. For thyroid issues, levothyroxine (Synthroid alternatives are covered on our site) or other replacements may help. For estrogen-related symptoms, options range from lifestyle changes and supplements like indole-3-carbinol to prescribed hormone therapy such as Premarin when appropriate. Low testosterone has replacement choices too, but each carries benefits and risks. Always review side effects and interaction details with your clinician.

Want to save on meds? Use trusted online pharmacy reviews, compare prices, and ask your prescriber about generic options. Our site has guides on safe online pharmacies and cost-saving tips. Be careful with supplements—some help, some interfere with prescriptions.

If you have sudden, severe symptoms—chest pain, fainting, severe breathing trouble, or very heavy bleeding—seek emergency care. For most other hormone concerns, start with symptom tracking, a set of basic labs, and a calm conversation with your primary care provider. You’ll get faster answers and better treatment when you bring clear notes and the right tests to the visit.
