PMS risk reduction

Overview

Premenstrual syndrome, or PMS, is a group of physical and emotional symptoms that many people experience in the days before their period starts. It usually goes away once the period begins or shortly after. PMS is linked to the natural changes in hormone levels during the monthly cycle.

Yes, PMS is very common. Most people who have periods experience at least some mild symptoms before their period. For some, the symptoms are strong enough to affect daily life.

PMS typically affects people in their 20s to 40s who are having regular menstrual cycles. It can also affect teenagers after their periods start. Symptoms usually stop after menopause.

Symptoms

Common symptoms

• Bloating or feeling puffy
• Breast tenderness or swelling
• Headaches
• Tiredness or low energy
• Irritability or mood swings
• Feelings of anxiety or sadness
• Difficulty sleeping
• Food cravings or changes in appetite
• Cramps or pelvic discomfort

Causes

Main causes

• Changing levels of hormones, such as oestrogen and progesterone, during the monthly cycle
• Changes in brain chemicals that affect mood and emotions
• The body's response to normal hormone changes, which can cause inflammation and fluid retention

Risk factors

• High levels of stress
• Family history of PMS or severe premenstrual symptoms
• Being in your 20s to 30s
• Smoking
• Poor sleep or low physical activity
• A history of depression or anxiety

When to see a doctor

See a doctor urgently if:

• If you have thoughts of harming yourself or feel hopeless, get help immediately.
• If your symptoms are so severe that you cannot do basic daily tasks or keep yourself safe.

Book a routine appointment if:

• If PMS regularly disrupts work, school, or relationships
• If you have kept a symptom diary and notice a clear pattern but want help managing it
• If you are considering treatment options and want advice from a healthcare professional

Diagnosis

A healthcare provider usually diagnoses PMS by asking about your symptoms and asking you to keep a symptom diary for at least two full menstrual cycles. There is no single test for PMS.

Tests that may be done

• A symptom diary to track physical and emotional symptoms day by day
• A review of your medical history and menstrual history
• A physical examination if needed to rule out other conditions
• Sometimes blood tests to check for other causes such as thyroid problems or anaemia

What to expect at your appointment

During the appointment, your provider will ask when symptoms happen, how long they last, and how they change after your period starts. They may ask about your daily routines, stress, and mental health. This information helps you both make a plan that fits your situation.

Treatment

Treatment for PMS focuses on easing symptoms and improving quality of life. It usually starts with self-care and lifestyle changes. If these are not enough, a healthcare professional can suggest other approaches based on your needs and health history.

Self-care at home

• Track your cycle with a diary or app to learn your pattern
• Limit caffeine, alcohol, salty foods, and sugary foods before your period
• Try stress-reducing activities such as deep breathing, meditation, or gentle stretching
• Prioritise sleep by going to bed and waking up at regular times
• Use a warm bath or heat pack for cramps and muscle tension

Medical treatments

Some people benefit from cognitive behavioural therapy, or CBT, which helps change how you think about and cope with symptoms. Others find help from certain hormonal contraceptives, nutritional supplements, or anti-inflammatory pain relief. A doctor or pharmacist can recommend options that are safe for you. These are general approaches, not specific products.

When is surgery considered?

Surgery is not a treatment for PMS in almost all cases. It is considered only in extremely rare situations and only after careful discussion with a specialist.

Living with this condition

Living with PMS is about learning your own cycle and planning ahead. If you know your lower-mood days tend to come a week before your period, you can build in extra rest and avoid scheduling stressful events for those days.

Lifestyle tips

• Keep a regular sleep schedule
• Get 30 minutes of moderate movement most days
• Take short breaks during the day to breathe or stretch
• Share your needs with people you trust

Diet and exercise

A balanced diet with regular meals helps keep blood sugar steady, which may reduce PMS symptoms. Cutting back on salty foods, caffeine, and sugar close to your period can help with bloating and mood. Regular exercise, even walking, can lift your mood and ease cramps.

Mental health and emotional wellbeing

PMS can affect how you feel emotionally, especially if it is severe. It is not weakness or 'all in your head'; it is a physical and emotional response to hormonal changes. If you feel anxious, tearful, or irritable each cycle, talk to a healthcare professional.

Prevention

PMS cannot always be prevented because it is linked to your natural hormone cycle. But many people can reduce how intense their symptoms feel by focusing on regular sleep, balanced meals, movement, and stress management.

Vaccines

There is no vaccine for PMS.

Screening programmes

There is no routine screening test for PMS, but keeping a symptom diary can help you and your healthcare provider spot patterns and decide what support you need.

Complications

If left untreated

• Severe PMS can make it hard to keep up with work, school, or relationships
• It can increase feelings of anxiety or depression
• It may stop people from enjoying activities or socialising each month

Long-term outlook

The outlook for PMS is good. With the right support and self-care, most people see their symptoms become more manageable. Even if symptoms are severe for a while, talking to a healthcare professional and building a plan can make a real difference.
