PMS screening test preparation

Overview

Premenstrual syndrome (PMS) is a set of physical and emotional symptoms that happen in the days before your menstrual period. A screening test helps doctors see if your symptoms are linked to your cycle, usually by tracking them over a few months.

Yes, PMS is very common. Many women experience at least a few symptoms regularly.

PMS affects women and people with menstrual cycles, most often between their late teens and mid-40s. It can also affect those with heavy or painful periods.

Symptoms

Common symptoms

• Mood swings or irritability
• Feeling sad or depressed
• Trouble sleeping
• Fatigue and low energy
• Bloating and water retention
• Breast tenderness
• Headaches
• Cravings for sweet or salty foods

Symptoms in children

• PMS can begin in teenagers after their first period. Symptoms may include more moodiness, acne, and stomach discomfort.

Symptoms in older adults

• During perimenopause (the years before menopause), PMS symptoms may become more intense or change pattern. Some women notice new or worsening symptoms until menopause.

Causes

Main causes

• The exact cause of PMS is not fully known, but it is linked to natural changes in hormones during your menstrual cycle.
• Changes in brain chemicals called neurotransmitters, especially serotonin, may also play a role.

Risk factors

• History of depression or mood disorders
• High levels of stress
• Lack of regular exercise
• Unhealthy diet (high in salt, sugar, and processed foods)
• Family history of PMS

When to see a doctor

See a doctor urgently if:

• If you have thoughts of self-harm or feel unable to control your emotions
• If symptoms suddenly become very severe

Book a routine appointment if:

• If PMS regularly interferes with your work, school, or relationships
• If you want to confirm a diagnosis and explore treatment options
• If your symptoms are not relieved by simple lifestyle changes

Diagnosis

There is no single blood test for PMS. Diagnosis is based on your symptoms and their timing. Your doctor will likely ask you to keep a daily diary of symptoms for at least two menstrual cycles.

Tests that may be done

• Symptom diary or chart to track physical and emotional changes
• Physical exam to rule out other conditions
• Blood tests (for example, to check thyroid function) if your doctor thinks other causes may be involved

What to expect at your appointment

Your doctor will explain how to record your symptoms each day. You may also have a pelvic exam if needed. After a few cycles, you will review the diary together to see if your symptoms follow a pattern linked to your period.

Treatment

PMS is managed by relieving symptoms. Many women feel better with healthy habits and support. For more bothersome symptoms, there are medical options your doctor can discuss with you.

Self-care at home

• Exercise regularly (like walking, swimming, or cycling) for at least 30 minutes most days
• Eat a balanced diet with plenty of fruits, vegetables, and whole grains
• Get 7 to 9 hours of sleep each night
• Try stress-reducing activities like deep breathing, yoga, or meditation
• Limit salt, caffeine, and alcohol, especially in the week before your period

Medical treatments

Your doctor may suggest over-the-counter pain relievers for cramps or headaches. Prescription options include medications that affect hormone levels (such as certain birth control pills) or antidepressants that adjust serotonin. Always talk to your doctor about what might be right for you.

When is surgery considered?

Surgery is not a common treatment for PMS. In very rare cases of severe PMDD (a more extreme form of PMS) that does not respond to other treatments, a doctor might discuss options like removing the ovaries, but this is only considered after careful evaluation.

Living with this condition

Living with PMS means knowing your cycle and planning ahead. Tracking your symptoms can help you predict when you might need extra rest or support. On symptom days, allow yourself gentle activities and self-care.

Lifestyle tips

• Keep a symptom diary to understand your pattern
• Schedule important tasks during the weeks you feel best
• Talk with family or close friends about how PMS affects you
• Maintain a consistent sleep and meal schedule

Diet and exercise

Eating small, frequent meals can help keep blood sugar steady. Include complex carbohydrates, protein, and healthy fats. Moderate exercise like brisk walking or swimming can boost your mood and energy.

Mental health and emotional wellbeing

PMS can make you feel irritable, anxious, or down. These feelings are real and can affect your wellbeing. If you have persistent sadness or worry, speak with your doctor. Counseling and support groups may also help.

Prevention

There is no sure way to prevent PMS, but living a healthy lifestyle may reduce how severe your symptoms are. Regular exercise, a balanced diet, and good stress management can all help.

Screening programmes

There is no routine screening test for PMS. Keeping a symptom diary is the best way to identify the condition and prepare for a discussion with your doctor.

Complications

If left untreated

• Severe PMS can lead to feelings of depression or anxiety
• May affect relationships, work, and daily activities
• Some women develop PMDD (premenstrual dysphoric disorder), a more serious form of PMS

Long-term outlook

With the right support and treatment, most women with PMS find their symptoms become much more manageable. Many women feel significantly better with lifestyle changes and medical help. PMS usually goes away after menopause, so it is a condition that can improve over time.
