A few days before your period, you may notice that you feel different physically or emotionally. For some people, these changes are mild and pass without much disruption. For others, they can interfere with everyday activities.
When symptoms follow a recurring pattern before your period and improve after it begins, they may be related to premenstrual syndrome (PMS). Understanding when your symptoms occur, how they affect you and whether the pattern repeats across menstrual cycles can help you recognise PMS and decide whether you need additional support.

Premenstrual syndrome, commonly called PMS, refers to a group of physical, emotional and behavioural symptoms that occur during the time before a menstrual period.
The symptoms typically follow a cyclical pattern, appearing before menstruation and improving after the period begins. However, the type, severity and timing of symptoms can differ from person to person and may also vary from one cycle to another.
Premenstrual syndrome symptoms can affect both physical and emotional well-being. When looking at PMS symptoms that women experience, the type and intensity can vary, with some noticing only mild changes and others experiencing more noticeable symptoms.
Common physical symptoms may include:
● Bloating
● Breast tenderness
● Headaches
● Tiredness or low energy
● Muscle or joint aches
● Changes in appetite
These may include:
● Irritability
● Mood changes
● Feeling anxious or low
● Difficulty concentrating
● Changes in sleep
● Feeling more emotional than usual
The presence of one or more of these symptoms does not necessarily mean you have PMS. The timing and recurring pattern of symptoms in relation to your menstrual cycle are important in identifying PMS.

The exact cause of PMS is not fully understood. It is thought to be related to the hormonal changes that naturally occur during the menstrual cycle and how the body and brain respond to them.
People may respond differently to these hormonal changes, which may explain why some experience noticeable PMS symptoms while others have few or none.
PMS is therefore not simply a sign of a “hormonal imbalance”. Symptoms can occur as the body responds to the normal hormonal fluctuations of the menstrual cycle.
The pattern of your symptoms can be just as important as the symptoms themselves. PMS symptoms typically:
● Develop in the days or weeks before a period.
● Follow a similar pattern across menstrual cycles.
● Improve after the period begins.
Keeping a record of your symptoms and when they occur over a few menstrual cycles can help you identify whether a recurring premenstrual pattern exists. You can also note how much the symptoms affect your work, sleep, relationships or usual activities.
Symptoms such as headaches, tiredness, mood changes or bloating can occur for many reasons. If they do not follow a clear pattern around your periods, your doctor may consider whether another condition could be contributing.
PMS can affect people differently. For some, symptoms are noticeable but manageable. For others, they may make it harder to concentrate at work or studies, sleep well, exercise, manage everyday responsibilities or interact comfortably with others.
What matters is not simply how many symptoms you experience, but how much they interfere with your usual life. If premenstrual symptoms are consistently having a significant impact, discussing them with a gynaecologist can help determine whether further assessment or treatment may be useful.
A small number of people experience severe premenstrual symptoms that substantially affect daily functioning. This may be associated with premenstrual dysphoric disorder (PMDD), which requires medical assessment rather than being considered simply a more uncomfortable period.
No single approach works for everyone with PMS. PMS symptom management depends on which symptoms you experience, how severe they are and how much they affect your daily life.

Certain lifestyle measures may help reduce or manage symptoms for some people. These include:
● Staying physically active with regular exercise
● Getting adequate and consistent sleep
● Eating balanced meals regularly
● Finding practical ways to manage stress
It can be useful to observe whether particular habits seem to make your symptoms better or worse.
If symptoms continue despite lifestyle measures or become difficult to manage, a doctor may discuss PMS treatment options based on your individual symptoms and needs.
Treatment may include medicines to relieve particular physical symptoms, hormonal treatment or medicines that help manage significant mood-related symptoms. The appropriate approach depends on the symptoms involved, their severity, your medical history and whether pregnancy is being planned.
Consider speaking to a gynaecologist if your premenstrual symptoms:
● Regularly interfere with work, studies, sleep, relationships or everyday activities
● Are becoming more difficult to manage
● Do not improve despite self-care measures
● Do not follow a clear premenstrual pattern
A medical assessment can help establish whether your symptoms are related to PMS or whether another condition may be contributing. This can also help determine the right management approach for you.
PMS does not look the same for everyone, and the support you need will depend on your symptoms and how they affect you. Recognising a recurring premenstrual pattern can make it easier to discuss your concerns with your gynaecologist and identify an appropriate approach to managing them.
Lifestyle measures may be sufficient for some people, while others may benefit from medical guidance or treatment. If symptoms persist or significantly affect your everyday life, discussing them with a gynaecologist can help you find an approach suited to your needs.

Common PMS symptoms may include bloating, breast tenderness, headaches, tiredness, mood changes, irritability, difficulty concentrating and changes in sleep or appetite. Symptoms vary from person to person and may also differ between menstrual cycles.
The exact cause of PMS is not fully understood. It is thought to involve hormonal changes during the menstrual cycle and individual sensitivity to those changes. Changes in brain chemicals involved in mood regulation, such as serotonin, may also play a role.
Regular physical activity, adequate sleep, balanced eating habits and stress management may help manage PMS symptoms for some people. Tracking symptoms across menstrual cycles can also help identify patterns and understand what may make them better or worse.
Lifestyle changes may reduce the frequency or severity of PMS symptoms for some people, although their effects vary. If symptoms continue despite these measures or significantly affect daily life, discuss them with a gynaecologist.
