Hormones & Metabolism
Why are your mood or cycle changing?
Many women experience mood swings, low energy, poor sleep, or changes in their cycle. These symptoms can be signs of hormonal imbalances, e.g. related to PMS, or may point to the onset of perimenopause.
Why does your body feel out of balance?
When your body feels different and you suddenly experience mood swings, sleep problems, or cycle irregularities, it is often not a coincidence. Many women experience these changes in the context of PMS or on the path to menopause.
Hormones regulate key functions like mood, sleep, energy, and reproductive health. Even small changes in oestrogen and progesterone can noticeably affect how you feel day to day.
For some women, these symptoms can also point to conditions such as PCOS (polycystic ovary syndrome), where hormonal imbalance affects the menstrual cycle, energy levels, and overall wellbeing.
Up to 70% of women with PCOS remain undiagnosed worldwide and experience symptoms like hormonal imbalances and irregular cycles without knowing why.

You may have a hormonal imbalance if you experience these symptoms.
Hormonal changes can be subtle but persistent. Your body may be signalling imbalance if you notice:
Unexplained weight gain or difficulty losing weight
Changes in your hormonal balance can affect your metabolism and make it easier for your body to store weight - even when diet and exercise have not changed.
PMS or cycle irregularities
Hormone fluctuations can affect your menstrual cycle and lead to irregular or missed periods as well as stronger PMS symptoms.
Low libido or reduced motivation
Hormonal imbalances and chronic stress can affect both your libido and your drive.
Trouble falling or staying asleep
Imbalances in stress and sleep hormones can make it harder to wind down, stay asleep, or wake refreshed.
Energy swings across the day
Blood sugar swings, stress, or hormonal shifts can cause highs and lows instead of steady energy.
Your symptoms are not random.
Many people try to treat individual symptoms in isolation – such as weight, sleep, or mood. In fact, these signals are often connected through the hormonal system. Hormones function as a network: when one part falls out of balance, it can affect multiple areas at once. Understanding this interplay is essential to moving beyond short-term fixes.
What can contribute to hormonal imbalance?
The symptoms above are common and often early signs of deeper imbalances. Hormonal changes are usually the result of multiple underlying physiological processes rather than just one single factor. Common causes include:
- General hormonal imbalance (e.g. oestrogen, progesterone, testosterone)
- PCOS or perimenopause / menopause transitions
- Thyroid disorders affecting metabolism and energy
- Chronic stress disrupting cortisol regulation
- Nutrient gaps that affect hormone production
These factors influence how your body regulates your metabolism, energy levels, sleep, and overall wellbeing.

Hormones influence your whole body
Hormones regulate how food becomes energy and how fat is stored. Disruption can contribute to weight change, difficulty losing weight, or uneven energy through the day.
Hormones like cortisol and melatonin regulate your sleep-wake cycle. When this balance is disrupted, it can become harder to fall asleep, stay asleep, or feel rested in the morning.
Hormones coordinate repair, immune function, and recovery after stress. When recovery is strained, you may notice longer rebound times or persistent tiredness.
Hormonal shifts can affect concentration, irritability, and emotional stability — often alongside stress and sleep.
Oestrogen, progesterone, and related hormones shape your cycle, period symptoms, and reproductive health. Imbalance may appear as irregular cycles or missed periods.
How can hormonal imbalance be identified?
Understanding hormonal health takes targeted testing rather than guesswork. Typical approaches include:
- Hormone panels (e.g. oestrogen, progesterone, testosterone, DHEA)
- Thyroid tests (TSH, T3, T4)
- Cortisol assessments to understand stress response
- Blood testing (e.g. iron, B vitamins, magnesium, micronutrients)
These tests help clarify what may be driving your symptoms at a deeper level.
What may improve when hormones are more balanced?
When underlying causes are addressed, your body can feel more stable and predictable. You may notice:
- More stable weight and metabolism
- Better sleep quality
- More even energy through the day
- Fewer PMS- or cycle-related complaints
- Greater overall wellbeing and balanced mood
