PMS procedure preparation

Overview

Premenstrual syndrome (PMS) is a common condition that causes physical, emotional, and behavioral symptoms in the days before your period. This article explains what PMS is, and it helps you know what to expect if your doctor suggests a procedure—such as a pelvic exam, ultrasound, or blood test—to investigate your symptoms or prepare for treatment.

Yes, PMS is very common. Up to 3 in 4 women experience some premenstrual symptoms, but only about 5–8% have symptoms severe enough to disrupt their daily life.

PMS affects women and people with menstrual cycles, most often between their late 20s and early 40s. It can be more bothersome if you have high stress, a family history of PMS, or a history of depression or anxiety.

Symptoms

Common symptoms

• Mood swings, irritability, or crying easily
• Tender or swollen breasts
• Bloating, gas, or a feeling of heaviness
• Headaches or tiredness
• Acne breakouts
• Food cravings or changes in appetite
• Trouble sleeping or restlessness
• Difficulty concentrating or remembering

Causes

Main causes

• Natural changes in hormone levels during the menstrual cycle, especially the drop in progesterone before your period
• Brain chemical changes, such as low serotonin, which can affect mood and energy
• Sensitivity to hormonal changes, which can trigger physical and emotional symptoms
• Nutritional factors, such as low calcium or magnesium, may play a role

Risk factors

• Age between the late 20s and 40s
• Chronic stress
• History of depression, anxiety, or bipolar disorder
• Family history of PMS
• Smoking, poor sleep, or heavy alcohol intake

When to see a doctor

See a doctor urgently if:

• If you have any emergency symptoms, call emergency services immediately.
• If you have thoughts of self-harm, seek urgent help right away.

Book a routine appointment if:

• If PMS symptoms regularly disrupt your work, studies, or relationships
• If your periods are very heavy, irregular, or you have bleeding between periods
• If you have not had a gynecological check-up for a while and you have concerns about your cycle

Diagnosis

There is no single test for PMS. Your doctor will talk with you about your symptoms and their timing. They may ask you to keep a symptom diary for two months to see if the symptoms follow a clear pattern. They may also do a pelvic exam, blood tests, or an ultrasound to rule out other conditions.

Tests that may be done

• Symptom diary kept over two menstrual cycles
• Pelvic exam (an internal examination)
• Blood tests to check hormone levels, thyroid function, or for anemia
• Ultrasound scan of the ovaries and uterus

What to expect at your appointment

Your doctor will ask about your cycle, medical history, and family history. A pelvic exam may feel a little uncomfortable but is usually quick. You can ask for a female doctor or a chaperone to help you feel at ease. If you are asked to keep a symptom diary, be as honest and detailed as you can—it helps with an accurate diagnosis.

Treatment

Treatment for PMS focuses on reducing symptoms and improving your quality of life. For many people, lifestyle changes come first. If those are not enough, your doctor may suggest medication or other approaches. Very rarely, surgery may be considered for severe and disabling symptoms that do not respond to other treatments.

Self-care at home

• Keep a symptom diary to predict when symptoms start and plan around them.
• Exercise regularly—brisk walking, swimming, or cycling all help.
• Try stress relief techniques like deep breathing, mindfulness, or yoga.
• Reduce salt, caffeine, and alcohol in the week before your period.
• Get enough sleep, and keep a regular sleep-wake schedule.
• Use a heat pad or take a warm bath to ease cramps or muscle aches.

Medical treatments

If lifestyle changes are not enough, your doctor may offer a range of options. These can include hormonal contraceptives (such as the pill or a hormonal coil) to help regulate your cycle, non-hormonal pain relievers (always used safely and as directed), and sometimes medicines that affect brain chemicals like serotonin. Your doctor will discuss the benefits and risks and help you choose what is right for you. Treatment is often reviewed after a few months.

When is surgery considered?

Surgery is only considered in extremely rare and severe cases of PMS that do not improve with any other treatment. Procedures such as removing the ovaries may be discussed, but they are major surgery with lasting effects. This decision is never taken lightly and requires specialist assessment.

Living with this condition

Living with PMS can be challenging, but you can take steps to make each month easier. Know your cycle and plan ahead for your 'symptom week'—for example, schedule lighter tasks at work or prepare your heat pad in advance. Being honest with family, friends, and your employer about what you need can also help.

Lifestyle tips

• Stay active for at least 30 minutes most days.
• Eat a balanced diet with whole grains, fruits, vegetables, and lean protein.
• Limit highly processed, salty, and sugary foods before your period.
• Practice good sleep hygiene: dark, quiet, cool room; no screens before bed.
• Try mindfulness or meditation to manage stress.

Diet and exercise

Regular exercise can improve mood, reduce bloating, and ease cramps. Aim for moderate activity like brisk walking or swimming on most days. Eating healthy carbohydrates at regular intervals can help steady your energy and blood sugar. Some studies suggest calcium and vitamin B6 might help, but always ask your doctor before starting any supplement.

Mental health and emotional wellbeing

PMS can cause real mood changes, irritability, and anxiety. These are not 'in your head'—they are symptoms of a physical cycle. If you feel low, anxious, or unable to cope, please talk to your doctor. A mental health professional can help you build coping skills, and sometimes medication is part of the plan. Remember, you deserve support, and seeking it is a sign of strength.

Prevention

PMS cannot be completely prevented, but you can help reduce how intense your symptoms feel. Keeping a menstrual diary, staying active, eating well, and managing stress can all make a difference. Planning ahead also helps you cope better when symptoms appear.

Vaccines

There is no vaccine that prevents PMS. Staying up to date with recommended general health vaccines is always wise, but they do not affect PMS.

Screening programmes

Routine gynecological screening, such as cervical screening (smear tests), is recommended according to national guidelines. These tests do not prevent PMS, but they help detect other health issues early. Follow the advice of your local health service.

Complications

If left untreated

• Severe PMS can affect your work, education, and relationships.
• It can contribute to anxiety or depression, especially if not managed.
• A more severe condition called premenstrual dysphoric disorder (PMDD) can develop and needs professional care.

Long-term outlook

Most people who experience PMS can find ways to manage their symptoms and improve their quality of life. With the right support—whether from lifestyle changes, medication, or emotional care—symptoms can become much more manageable. Be patient with yourself, and work closely with your healthcare team to find the approach that helps you best.
