Your cycle is run by a finely tuned conversation between hormones — chiefly oestrogen and progesterone, alongside the brain signals FSH and LH, plus thyroid hormones, insulin, and cortisol. When that conversation is disrupted, you feel it in your periods, mood, skin, sleep, and energy.
Signs of hormonal imbalance
- Irregular, very heavy, or absent periods
- Persistent acne, especially along the jaw
- Unexplained weight changes, fatigue, or hair changes
- Mood swings, anxiety, or low mood that tracks with your cycle
- Sleep problems and low libido
What disrupts hormones
Conditions like PCOS and thyroid disorders, chronic stress (cortisol), under-eating or over-exercising, poor sleep, and certain medications can all shift the balance. Life stages — puberty, pregnancy, and perimenopause — naturally do too.
Supporting balance
There’s no magic fix, but the fundamentals are powerful: adequate protein and fibre, stable blood sugar, strength training, good sleep, and stress management. Persistent symptoms deserve proper investigation — blood tests and a clinician — rather than guesswork or unregulated supplements. Tracking symptoms against your cycle helps reveal what’s hormonal.
