Hormones & Periods

Sourced guides to hormonal health and periods: hormonal imbalance symptoms, fatigue and other everyday symptoms, and when to see a doctor.

Your hormones shape your cycle, your energy and your mood. When periods become irregular, very painful or heavy, or when PMS starts to take over part of every month, it is worth understanding why.

These guides cover hormonal imbalance symptoms, irregular and missing periods, period pain and heavy bleeding, PMS and PMDD, and which hormone tests can help, with clear advice on when to see a doctor.

Hormone Testing

Hormone testing can help explain irregular cycles, fatigue, low mood, and fertility concerns — but only if you test the right hormones at the right point in your cycle.

Irregular & Missing Periods

Irregular or missing periods are one of the most common reasons women see a doctor, and the causes range from stress and thyroid problems to PCOS and perimenopause.

PMS & PMDD

PMS affects most menstruating women, but PMDD is a more severe, diagnosable condition that needs targeted treatment.
