Premenstrual tension (PMT) — sometimes called PMS — is something many women are familiar with, yet it’s still frequently dismissed or misunderstood. The good news? There’s a lot you can do about it.
PMT refers to a collection of physical and emotional symptoms that tend to appear in the one to two weeks before your period, typically easing off once your period arrives — and usually completely gone within a day or two of bleeding starting. By the middle of your cycle, most women feel back to themselves.
Importantly, PMT is not a sign that something is “wrong” with your hormones. It’s more about how sensitive your body and brain are to the natural hormonal shifts that happen every month — and that sensitivity is something we can work with.
What does PMT actually feel like?
PMT can show up both emotionally and physically. You might notice just a handful of these, or a mix of both — everyone’s experience is a little different.
Emotional & Mental
- Irritability or angry outbursts
- Anxiety or feelings of tension
- Brain fog or difficulty concentrating
- Low or flat mood
- Emotional sensitivity / mood swings
- Withdrawing from social situations
Physical
- Abdominal bloating
- Breast tenderness or swelling
- Headaches
- Joint or muscle aches
- Swelling of the hands or feet
- Fluid retention / weight gain
If you notice these symptoms cycling predictably each month and settling when your period arrives, that’s a strong sign PMT is at play. Keeping a simple diary for a couple of months can be really helpful in spotting the pattern.
What’s actually driving it?
PMT is driven by more than just hormones — there are several interconnected factors at play. Understanding these helps explain why a whole-body approach to diet and lifestyle makes such a difference.
Sensitivity to hormonal fluctuations The core issue isn’t usually having too many or too few hormones — it’s that the brain becomes more reactive to the normal hormonal shifts of the cycle. Think of it like a sensitivity dial being turned up in the weeks before your period.
Mood neurotransmitters (especially serotonin) Shifts in oestrogen and progesterone affect serotonin — your feel-good neurotransmitter. This directly contributes to mood changes, anxiety and low mood in the premenstrual phase. Supporting serotonin through diet, sleep, movement and light exposure can genuinely help.
Stress and the nervous system Chronic or ongoing stress interacts directly with reproductive hormones and is strongly linked to more severe PMT symptoms. If your PMT always feels worse during stressful periods of life, this is why.
Gut health and oestrogen metabolism Your gut microbiome plays a role in how well your body processes and clears oestrogen, and it’s also where the vast majority of serotonin is produced. A fibre-rich, varied diet supports both.
Inflammation Low-grade inflammation can amplify all of the above — worsening hormonal sensitivity, disrupting neurotransmitter balance, and increasing pain and bloating. This is one of the key reasons an anti-inflammatory diet has such a broad, meaningful impact on PMT.
Diet & lifestyle: what makes it better or worse
Research consistently shows that what you eat and how you live has a real, measurable effect on PMT severity. Here’s a practical overview:
Can worsen symptoms
- Ultra-processed foods (high in refined carbs, saturated fat, additives)
- A Western-style diet — research links this to significantly higher odds of PMT
- Low intake of omega-3 fats
- Blood sugar instability (skipping meals, high sugar intake)
- Low B vitamins, including thiamine and riboflavin
- Alcohol and excess caffeine
- High sodium / very salty foods (worsens bloating and fluid retention)
- Elevated BMI
- Sedentary lifestyle
- Chronic stress
- Poor sleep
Can reduce symptoms
- Mediterranean-style eating: oily fish, colourful vegetables, olive oil, nuts and seeds
- Low-GI foods and adequate protein at every meal to stabilise blood sugar
- Oily fish 2–3x per week; also walnuts, flaxseed and chia seeds for omega-3
- B vitamins and Vitamin D — found in wholegrains, eggs, dairy and sunlight
- Calcium — dairy, fortified plant milks, leafy greens
- Magnesium — seeds, dark leafy greens, dark chocolate
- Zinc — shellfish, meat, seeds
- Turmeric and ginger — natural anti-inflammatory support
- Regular movement — even gentle daily walking makes a difference
- Prioritising sleep and stress recovery
Want to know what’s right for you?
While these foundations are a great starting point, PMT is highly individual — what’s driving your symptoms may be quite different from someone else’s. Working one-to-one means we can look at your full picture: your cycle, your diet, your stress load, your sleep, and any underlying factors that might be contributing.
