Further Information:
Premenstrual Syndrome
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.
Further information about PMS can be obtained from:
Post-Natal Depression
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 of time.
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.
