PMS & PMDD support:
when hormones affect more than your period

If you find yourself becoming a completely different person in the days before your period, you're not imagining it — and you're not alone. Support is available.

Real conditions that affect every area of life

PMS and PMDD are not personality flaws. They are real, recognised health conditions that can significantly affect relationships, work, confidence and daily wellbeing.

As a NIMH-registered Medical Herbalist specialising in women's hormone health, I take a whole-person approach to understanding why symptoms occur and how herbal medicine may help support your physical and emotional wellbeing throughout your cycle.

"Perhaps your confidence disappears overnight. Or perhaps you're experiencing intense emotional symptoms that leave you wondering why your cycle has such a powerful impact on your life."

These experiences are valid. And they deserve proper support — not dismissal.

Symptoms typically improve once menstruation begins, which is why tracking your cycle is often the first step toward understanding your unique pattern.

PMS and PMDD: what's the difference?

Both conditions involve premenstrual symptoms, but their severity and impact on daily life can differ significantly.

PMS

Premenstrual Syndrome describes a collection of physical and emotional symptoms that occur before menstruation. Symptoms can range from mild to moderate and are experienced by many women at some point in their lives.

PMDD

Premenstrual Dysphoric Disorder is a more severe condition that can significantly impact daily functioning, relationships and quality of life. It is a recognised health condition that warrants proper support and assessment.

Common signs of PMS & PMDD

Symptoms vary from person to person and may change across different life stages. You may experience some, several, or all of the following in the days before your period:

Anxiety
Low mood
Irritability
Rage or anger
Tearfulness
Sleep disturbances
Brain fog
Fatigue
Breast tenderness
Bloating
Food cravings
Headaches

Symptoms typically improve once menstruation begins. Tracking your cycle over several months can help identify patterns.

It's not "just hormones"

While hormonal fluctuations play an important role, PMS and PMDD are often influenced by multiple interconnected factors. This is why support should extend beyond symptom management alone.

Sleep

You shouldn't have to just put up with it.

Many women have been told PMS is simply something they must manage on their own. Others feel embarrassed discussing the emotional impact their cycle has on work, relationships and everyday life.

Been told that what you're experiencing is a normal part of being a woman and something you simply have to put up with.

Felt embarrassed discussing the emotional impact your cycle has on relationships, work and daily life.

Wondered whether the person you become before your period is "the real you" — and felt confused or ashamed by that.

Struggled to get a PMDD diagnosis recognised or taken seriously by healthcare providers.

Severe PMS and PMDD are not character flaws. They are health concerns that deserve understanding and support.

How herbal medicine may help

Every herbal prescription is individually tailored to the person, not just the diagnosis.

Working alongside conventional healthcare

Herbal medicine works best as part of a collaborative approach. Where appropriate, I work alongside GPs, specialists and existing treatment plans to ensure your care remains safe, joined-up and supportive.

If you are currently taking antidepressants, hormonal contraception or other medications, these will be reviewed carefully before any recommendations are made.

"I believe herbal medicine and conventional medicine are most powerful when they work together — not in opposition."

Frequently asked questions

What's the difference between PMS and PMDD?

PMS involves physical and emotional symptoms before menstruation. PMDD is more severe, causing significant mood changes, emotional distress and disruption to daily functioning.

Why do I feel like a different person before my period?

Hormonal changes can affect neurotransmitters, mood regulation, sleep, energy and emotional resilience. Many women with PMS or PMDD describe feeling unlike themselves in the luteal phase.

Can PMS cause anxiety?

Yes. Anxiety is a common symptom of PMS due to hormonal fluctuations throughout the cycle. Some women notice mild anxiety; others experience symptoms that significantly affect daily life.

Can PMDD get worse during perimenopause?

For some women, PMDD symptoms may worsen during perimenopause due to increased hormonal fluctuations, resulting in more noticeable emotional and physical symptoms throughout the cycle.

How do I know if I have PMDD?

If your symptoms are severe, consistently occur during the luteal phase and significantly affect work, relationships or quality of life, it may be worth discussing PMDD with your GP and tracking symptoms over several cycles.

Can I take herbal medicine alongside antidepressants?

Potential interactions must always be assessed individually. During your consultation, all medications and supplements will be reviewed before any recommendations are made.

Can I work with you online?

Yes. Consultations are available online throughout the UK, so you can access support from wherever you are.

How long does support usually take?

This varies depending on symptom severity, health history and individual goals. We discuss realistic timelines from the outset of working together.
