Hormonal changes: signs, tests, and what you can do now

Sudden mood swings, tiredness that won’t quit, irregular periods, or unexplained weight shifts — sound familiar? Those are common signs your hormones might be out of balance. Hormones affect energy, mood, sleep, weight, and sex drive. The good news: you don’t have to just live with it. Small steps and the right tests can point the way forward.

Common causes and typical symptoms

Hormone shifts happen for many reasons. Pregnancy, postpartum recovery, puberty, perimenopause and menopause are natural life stages that change hormone levels. Other causes include thyroid problems, polycystic ovary syndrome (PCOS), stress (high cortisol), rapid weight change, some medications, and certain medical conditions.

Symptoms vary but watch for: changes to your period (heavy, light, missed), hair loss or extra hair growth, acne, hot flashes or night sweats, persistent fatigue, low libido, anxiety or depression, and unexpected weight gain or loss. If you notice multiple signs at once, that’s a stronger clue a hormone issue may be involved.

What tests and checks help

If you see a doctor, they’ll often start with a few blood tests. Common ones are TSH and free T4 for your thyroid; LH, FSH, and estradiol for ovarian function; total testosterone; prolactin; fasting glucose or HbA1c for blood sugar; and sometimes morning cortisol. For suspected PCOS, doctors look at testosterone, menstrual pattern, and an ultrasound. Use results plus symptoms — labs alone don’t tell the full story.

While you wait for an appointment or results, try these practical steps:

- Track symptoms for 1–3 months. Use an app or a simple diary: note sleep, mood, period details, energy, and diet. Patterns make diagnosis easier. - Prioritize sleep. Aim for 7–9 hours and a consistent bedtime. Poor sleep disrupts hormones like cortisol and insulin. - Move regularly. Strength training twice a week plus 30 minutes of walking can improve insulin sensitivity and hormonal health. - Cut back on high-sugar, highly processed foods that spike insulin. Focus on whole foods, lean protein, fiber, and healthy fats. - Manage stress with 5–15 minutes of breathing, short walks, or whatever relaxes you. Chronic stress keeps cortisol high and throws off other hormones.

Some supplements can help, but evidence varies. Vitamin D deficiency is common and often worth replacing after testing. Magnesium and omega-3s can support sleep and mood for some people. Don’t start supplements without checking with your doctor, especially if you take other medications.

When to see a doctor now: missed periods for 3+ months, sudden heavy bleeding, severe hair loss, sudden weight change of 10+ pounds without reason, chest pain, fainting, or suicidal thoughts. If you’re trying to get pregnant and cycles are irregular, see a clinician earlier.
