What is PMS?
PMS (also known as PMT – Premenstrual Tension) happens in the 14 days preceding a woman’s monthly period. As well as having a physical impact upon the body, PMS can have an emotional one, too.

Severity of PMS symptoms can vary from one person to the next (and from one month to another), but most women agree that PMS can be difficult to cope with. It can also impact upon your relationship with your partner as well as your interpersonal relationships with friends and work colleagues, etc. The list of PMS symptoms in the next section will help to explain why.

Symptoms of PMS include:

A bloated feeling which is often accompanied by cramps, abdominal pain and pelvic pain

Breast tenderness

Increased heart rate

Muscle and joint pain

Lower back pain

Headache (and sometimes migraine)

Weight gain

Swollen ankles




Disturbed sleep

Diminished libido (lack of interest in sex)

A feeling of irritability and tension

Sudden mood swings

An inability to concentrate as well as you normally would

Anxiety, anger, and intense emotional upset


Also, due to PMS, many women develop depressive illness, as well as the aforementioned mood disorders. Please see contact details for the Depression Alliance at the Advice & Support section at the foot of this article.

Although the precise cause of PMS is as yet unknown (despite considerable worldwide research), it is suggested that there may be a number of possible causes. These include:

Hormonal changes – the onset of PMS generally occurs as a result of hormone level fluctuation at particular times each month

Neurochemical changes – the mood controlling chemicals in the brain (e.g., Serotonin) interact negatively with your hormonal changes and therefore impact upon your emotional state(s) during this time

Diet ¬– a poor diet which does not include sufficient quantities of certain vitamins and minerals can exacerbate symptoms

Treatments for PMS, which are intended to ease symptoms, include:

Hormone treatments – these can include the contraceptive pill or progestogen

Anti-depressants – to help boost Serotonin levels so that feelings of depression and anxiety may be significantly reduced

Self-help measures – things you can do to help you cope better with PMS each month can include: exercising (to boost ‘feel good’ endorphins and reduce aggressive mood swings); maintain a healthy diet with plenty of fruit and vegetables; and supplementing your diet with vitamins.
