What is PMS?

You may experience physical and emotional symptoms about one week before your period. This is called ‘premenstrual syndrome’ or ‘PMS’.

Most women have one or two symptoms that can be easily managed. Symptoms usually stop after your period starts.

PMS symptoms can be worse in teenage years and in the lead-up to menopause (perimenopause), which may be due to changing hormone levels.

PMS is different to premenstrual dysphoric disorder (PMDD), which is a condition that causes severe emotional and psychological distress.

What are the symptoms of PMS?

Everyone is different. Some people have no symptoms and others experience emotional and physical symptoms every month. Symptoms can also vary from one cycle to the next.

Emotional symptoms

Common emotional symptoms include:

  • irritability
  • anxiety
  • lower ability to cope
  • difficulty concentrating
  • mood changes
  • sadness.

Physical symptoms

Common physical symptoms include:

  • cramping in the pelvic area
  • bloating around the belly (abdomen)
  • breast swelling and tenderness
  • fluid retention (swollen fingers or ankles)
  • skin problems such as acne.

You may also experience:

  • headaches
  • tiredness, lethargy, insomnia
  • constipation, diarrhoea or both
  • food cravings
  • aches and pains.

What causes PMS?

It’s not clear why some people have PMS. It may be associated with the hormone progesterone interacting with certain chemicals in the brain. Other factors can influence symptoms, including stress levels, physical and emotional health and lifestyle.

Managing PMS

There are many ways to manage PMS symptoms.

Healthy lifestyle

A healthy lifestyle can help reduce PMS symptoms.

Physical activity increases 'feel-good' hormones (endorphins), which help you feel more relaxed. Aim to do 30 minutes of moderate-intensity activity most days, especially when symptoms are at their worst.

You can reduce stress levels by taking time to relax and do things you enjoy. You can also try different relaxation techniques such as yoga and meditation.

Quality sleep can also help to reduce stress.

Eat a well-balanced diet, including plenty of vegetables, fruit, protein and whole grains. Also, drink lots of water (up to 2 litres each day) and cut back on sugary, caffeinated and alcoholic drinks.

If you smoke, try to quit. For help, call Quitline on 13 7848 or visit www.quit.org.au

Complementary therapies

Some people find complementary therapies such as acupuncture, naturopathy and herbs help to relieve emotional and physical symptoms of PMS. But more research is needed to understand the effectiveness of these therapies.

Vitamins, minerals and herbs

Common supplements include:

  • chaste tree – to reduce mood swings and irritability
  • vitamin B6
  • magnesium – to improve mood
  • calcium – about 600 mg twice a day
  • evening primrose oil – for breast swelling and pain.

Tell your doctor if you take any supplements, as they can affect other medicines.

Hormonal treatments

Hormonal treatments (e.g. the Pill) suppress ovulation and reduce hormone levels during your menstrual cycle, which can help with symptoms.

Medicines

Some medicines may help reduce PMS symptoms. For example, certain antidepressants and anti-inflammatories. Ask your doctor for more information.

Practical ideas

If you have tender, painful breasts before your period, try wearing a soft cotton or bamboo bra on those days.

Many people find using a heat pack on their belly or lower back eases cramping pain. You could also try relaxing in a warm bath.

When to see your doctor

It's not normal to have premenstrual symptoms that stop you from doing everyday activities. If you experience severe symptoms, see your doctor. They will investigate possible causes and recommend treatments that will help relieve symptoms.
