PMS specialist tests overview

Overview

Premenstrual syndrome (PMS) is a common set of physical and emotional symptoms that happen in the days before your period starts. It usually goes away once your period begins.

Yes, PMS is very common. Most people who menstruate have experienced some PMS symptoms at some point in their lives.

PMS affects people of reproductive age who have menstrual cycles. It can occur in teenagers and continue until menopause.

Symptoms

Common symptoms

• Bloating and water retention
• Breast tenderness
• Mood swings, irritability, or anxiety
• Feeling unusually tired (fatigue)
• Food cravings (especially for sweet or salty foods)
• Difficulty sleeping
• Headaches or muscle aches

Symptoms in children

• Adolescents may experience similar symptoms to adults, such as mood changes, bloating, and cramps.

Symptoms in older adults

• PMS symptoms typically improve after menopause, but perimenopause (the years leading up to menopause) can bring similar symptoms due to changing hormone levels.

Causes

Main causes

• The exact cause is not known, but it is linked to changes in hormone levels during the menstrual cycle.
• Brain chemicals called neurotransmitters (such as serotonin) may also play a role.

Risk factors

• High stress levels
• A family history of PMS
• Being overweight or obese
• Lack of regular exercise
• A diet high in salt, sugar, or caffeine

When to see a doctor

See a doctor urgently if:

• If you have thoughts of harming yourself or others
• If your symptoms are so severe that you cannot function normally

Book a routine appointment if:

• If your PMS symptoms are affecting your daily life despite trying self-care steps
• If you want help managing your symptoms or are unsure what they mean

Diagnosis

There is no single test for PMS. Your doctor will diagnose it by talking with you about your symptoms and when they happen. They may ask you to keep a symptom diary for a few months.

Tests that may be done

• A symptom diary or calendar to track your feelings and physical changes each day
• A physical exam, including a pelvic exam, to rule out other causes
• Blood tests to check for other conditions like thyroid problems or anemia

What to expect at your appointment

Your doctor will ask about your symptoms, when they start, and how they affect your life. They may also rule out other health issues. You might leave with a diary to fill out and a plan to come back after a few months.

Treatment

Treatment for PMS focuses on relieving symptoms and helping you feel better. Many people start with lifestyle changes. If symptoms are severe, your doctor may suggest medications or other therapies.

Self-care at home

• Exercise regularly (even a daily walk can help)
• Eat a balanced diet with plenty of fruits, vegetables, and whole grains
• Reduce salt, sugar, caffeine, and alcohol in the days before your period
• Get enough sleep (aim for 7–9 hours per night)
• Try stress-reducing techniques like yoga, meditation, or deep breathing

Medical treatments

Your doctor may recommend over-the-counter pain relievers, hormonal birth control (like the pill), or antidepressant medications to help with mood symptoms. Always talk to your healthcare provider before starting any new medication or supplement. They can help you find a treatment that is safe and effective for you.

Living with this condition

Keeping a symptom diary can help you predict when your symptoms will start and plan ahead. For example, you might schedule important tasks for after your period or give yourself extra rest during tough days.

Lifestyle tips

• Stay active with regular exercise
• Practice good sleep habits
• Manage stress with activities you enjoy
• Talk to friends or family about how you feel

Diet and exercise

Eating small, frequent meals can help keep your blood sugar stable. Choose complex carbohydrates like oatmeal, brown rice, and beans. Include calcium-rich foods like yogurt, milk, and leafy greens. Even 30 minutes of moderate activity most days can improve your energy and mood.

Mental health and emotional wellbeing

PMS can affect your mood, causing irritability, anxiety, or sadness. These feelings are real and can be hard to handle. If they become overwhelming or last beyond your period, talk to your doctor. You are not alone, and support is available.

Prevention

There is no known way to prevent PMS entirely, but a healthy lifestyle — including regular exercise, a balanced diet, and stress management — may reduce how severe your symptoms are.

Complications

If left untreated

• Severe PMS can make it hard to work, go to school, or maintain relationships.
• Some people may develop a more severe form called premenstrual dysphoric disorder (PMDD), which requires medical attention.

Long-term outlook

With the right approach, most people can manage PMS well and live a full, active life. Symptoms often improve with age and usually stop after menopause. If you are struggling, help is available — talk to your healthcare provider.
