Many women suffer from a condition called
premenstrual syndrome or PMS. This is commonly
known as PMT (premenstrual tension) because of
the anxiety and bad temper often associated with
it. However, there are many other symptoms that
occur with PMS including depression, bloating and
breast tenderness. It is not just your symptoms
that decide whether you have PMS but the time at
which they are at their worst.
PMS is characterised by the symptoms that occur
during the days leading up to your period and are
then completely relieved by menstruation. The
cause of PMS is not completely understood but it
is believed to be related to the hormonal changes
that occur during the monthly cycle. Many
women obtain relief from their symptoms when
their hormonal balance is altered with a medicine
prescribed by their doctor.
Many mothers experience short-term periods of
mild depression following the birth of their baby.
This is a common condition, usually occurring
three or four days after delivery, affecting at least
half of all new mothers who may feel tearful,
overwhelmed and irritable during this time.
Support, reassurance and rest can help these
feelings to pass within a few days.
However, if the anxiety does not improve, the
mother may be developing postnatal depression.
Up to 15 per cent of new mothers develop more
severe symptoms within 12 months of their child’s
birth. Postnatal depression (PND) is characterised
by marked low mood for a more prolonged period
Though it may take several weeks or months
until a full recovery is reached, PND is a treatable
condition from which the mother will get better.
Speak to your midwife, health visitor or doctor if
you have any further questions.
