What Is Premenstrual Syndrome?

Premenstrual syndrome (PMS), previously referred to as premenstrual tension (PMT), describes a range of emotional, physical, and behavioural symptoms that occur during the luteal phase of the menstrual cycle—the time between ovulation and the start of your period. Symptoms typically resolve once your period begins.

Approximately 90% of women experience some form of PMS, with 35% reporting significant interference with their daily lives. Symptoms often worsen in the mid-thirties and may be influenced by stress, genetics, diet, and chronic health conditions. For some women, severe symptoms may indicate Premenstrual Dysphoric Disorder (PMDD), a more intense form of PMS that requires specialised care.

Common Symptoms of PMS

PMS is associated with over 200 symptoms, but the most common include:

  • Irritability, mood swings, and depression.
  • Breast tenderness (mastalgia) and bloating.
  • Backache, changes in appetite, and food cravings.
  • Fatigue and difficulty concentrating.


For women with severe symptoms, PMS can significantly disrupt relationships, work, and daily routines. Recognising the impact of PMS is the first step toward finding relief.

Is PMS Impacting Your Life?

If PMS is impacting your quality of life, relationships, or ability to function, it’s time to seek support. Start by tracking your symptoms over 2–3 cycles to identify patterns. Keeping a diary or using a symptom questionnaire (available from organisations like the National Association for Premenstrual Syndrome) can provide valuable insights.

Consulting with a GP or a specialist like Dr. Orla Conlon at Marble Arch Health ensures a thorough diagnosis and access to effective treatments tailored to your needs.

Lifestyle Changes to Manage PMS

Simple Changes, Big Impact

Lifestyle adjustments can play a significant role in reducing PMS symptoms:

  • Diet: While no single diet cures PMS, eating complex carbohydrates with a low glycaemic index (e.g., whole grains, legumes) may help. Reducing salt, caffeine, and fat intake can also alleviate bloating, tension, and irritability.
  • Exercise: Regular physical activity can improve mood and reduce fatigue. Women with active lifestyles often report milder symptoms.
  • Counselling: Emotional support through counselling or therapy can help you manage stress and the behavioural impact of PMS.

Medical Treatments for PMS

Effective Medical Options

When lifestyle changes aren’t enough, medical treatments can help regulate your cycle and reduce symptoms:

  • The Combined Oral Contraceptive Pill: This prevents ovulation and stabilises hormonal fluctuations, easing symptoms in the second half of your cycle.
  • Oestrogen Patch and Progesterone Tablets: Used during the luteal phase, these hormonal therapies can balance fluctuations and reduce symptoms.
  • Antidepressants: Selective serotonin reuptake inhibitors (SSRIs) may be prescribed during the luteal phase for women experiencing severe depression or anxiety.
  • Hormonal Injections: GnRH analogues induce temporary menopause to alleviate symptoms. These are typically paired with hormone replacement therapy (HRT) to manage menopausal side effects like hot flushes.
  • Surgical Options: For women with severe symptoms, particularly those with PMDD, removing both ovaries (bilateral oophorectomy) may provide lasting relief. A hysterectomy may also be considered in specific cases, with careful evaluation and preparation.

Complementary and Nutritional Support

Additional Treatment Options

Some women find relief through vitamins, minerals, and herbal supplements. While results vary, options to consider include:

  • Vitamin E (400 IU/day): Reduces breast tenderness.
  • Magnesium (250–400 mg/day): Alleviates fluid retention, though high doses may cause diarrhoea.
  • Calcium (1,000 mg/day): Supports overall health and may help with PMS symptoms.
  • Agnus Castus (Chasteberry): Clinically proven to reduce PMS symptoms in some women.


It’s important to consult with a healthcare provider before trying supplements, as some herbal products can interfere with medications or cause side effects.

Your PMS Questions Answered

PMS symptoms are typically milder and manageable, whereas PMDD causes intense emotional and physical symptoms that significantly interfere with daily life. Tracking your symptoms and their severity over several cycles can help distinguish between the two. If your symptoms feel overwhelming, consult a specialist for evaluation.

Lifestyle factors like diet, exercise, and stress management can significantly influence PMS symptoms. Incorporating regular physical activity, reducing caffeine and salt intake, and seeking counselling can all help alleviate symptoms.
