screening for PMS

Overview

Premenstrual syndrome (PMS) is a group of physical and emotional symptoms that many people experience in the days before their period starts. These symptoms usually go away after the period begins. It’s not an illness you catch — it’s your body’s response to the natural hormone changes of your cycle.

Yes. Many people who menstruate have some PMS symptoms at times. It is most common in people in their 20s and 30s.

PMS affects people who are menstruating. It is more common in those with a history of anxiety or depression, or a family history of PMS.

Symptoms

Common symptoms

• Bloating and fluid retention
• Breast tenderness
• Fatigue and tiredness
• Mood swings or irritability
• Trouble sleeping
• Food cravings or changes in appetite
• Headaches
• Abdominal cramps

Causes

Main causes

• Hormone changes during the menstrual cycle
• Changes in brain chemicals (neurotransmitters) that affect mood and pain
• A higher sensitivity to normal hormone shifts

Risk factors

• Being in your late teens to early 40s
• A personal or family history of mood disorders
• High levels of stress
• Not getting enough regular exercise
• Poor sleep habits

When to see a doctor

See a doctor urgently if:

• If you have thoughts of harming yourself, call your local emergency number immediately.
• If you feel too distressed or overwhelmed to keep yourself safe, seek same-day urgent care.

Book a routine appointment if:

• If PMS symptoms regularly disrupt your work, study, or relationships
• If self-care steps have not helped after a few menstrual cycles
• If you want to check whether something else, like a thyroid condition or depression, could be causing your symptoms

Diagnosis

There is no single blood test or scan for PMS. A doctor usually makes the diagnosis by listening to your symptom history and asking you to keep a symptom diary for at least two months.

Tests that may be done

• Symptom diary to track when symptoms happen and how severe they are
• A physical exam to check for other possible causes
• Blood tests to rule out conditions like thyroid problems or anemia, if needed

What to expect at your appointment

Your doctor will ask you to describe symptoms, look at your diary, and may do a physical exam. They may also consider other conditions. The key pattern for PMS is symptoms in the week before your period that improve after it starts.

Treatment

Treatment for PMS focuses on easing symptoms and improving your quality of life. There is no one-size-fits-all approach. You and your healthcare provider can build a plan that fits your needs.

Self-care at home

• Keep a symptom diary to see patterns
• Practice stress-reducing techniques like deep breathing, meditation, or yoga
• Use a warm heat pack on your belly or lower back for cramps
• Try to get enough sleep each night
• Limit caffeine, alcohol, and salty foods in the week before your period
• Take gentle walks or other light exercise

Medical treatments

If self-care is not enough, your healthcare provider may talk with you about prescription medicines. Some medicines help steady mood, while others ease physical symptoms. Hormonal birth control may also be prescribed to reduce hormone swings. Pain relievers bought at a pharmacy can help with cramps and breast pain — ask your pharmacist which option is right for you. In some cases, doctors suggest vitamin or mineral supplements, but always ask before taking them.

When is surgery considered?

Surgery is not a treatment for PMS. Removing the uterus or ovaries is not recommended for PMS alone and would only be considered for other serious medical reasons.

Living with this condition

Track your cycle so you know when PMS symptoms are likely to appear. Plan lighter activities or easier meals for that time, and let close family or friends know you might need extra patience and support.

Lifestyle tips

• Use a period tracker or calendar to predict symptoms
• Build in relaxing activities in the days before your period
• Talk to your employer or school if symptoms make it hard to focus or work
• Stay connected with people who make you feel understood

Diet and exercise

Regular exercise of about 30 minutes a day can improve mood, reduce bloating, and boost energy. Eating balanced meals with vegetables, fruits, and whole grains helps keep your body steady. In the week before your period, try to limit salt, caffeine, and alcohol.

Mental health and emotional wellbeing

PMS can affect your mood, self-esteem, and relationships. You may feel irritable, tearful, or anxious for no clear reason. These feelings are real and manageable. If they feel overwhelming, or if you have thoughts of harming yourself, reach out for help right away.

Prevention

PMS cannot always be prevented, but you can reduce its impact with regular exercise, balanced eating, stress management, and good sleep habits.

Vaccines

There is no vaccine to prevent PMS.

Screening programmes

There is no routine screening test for PMS, like a blood test or scan. The best way to assess whether your symptoms follow a PMS pattern is to keep a detailed symptom diary over at least two months.

Complications

If left untreated

• Severe PMS can interfere with work, school, relationships, and quality of life.
• Some people develop premenstrual dysphoric disorder (PMDD), a much more severe form of PMS that can seriously affect mental health and needs medical support.

Long-term outlook

Most people with PMS can find relief with simple lifestyle changes and, if needed, professional care. Symptoms often become easier to manage over time. With the right support, you can feel more in control and enjoy your month without dreading that week.
