Premenstrual Tension and Irritability
Premenstrual tension (PMT) means irritability, anger, anxiety, low mood or feeling on edge in the 1 to 2 weeks before a period, easing within a few days after bleeding starts. Mild premenstrual mood changes affect most people who menstruate. When symptoms disrupt work or relationships, it is premenstrual syndrome (PMS), and severe, disabling mood symptoms are premenstrual dysphoric disorder (PMDD). Exercise, sleep, cutting caffeine and alcohol, and treatments such as SSRIs or hormonal contraception can help a great deal.
Also called: PMT, PMS mood symptoms, premenstrual irritability, premenstrual mood swings, PMDD

PMS vs PMDD
| Premenstrual symptoms (normal) | PMS | PMDD | |
|---|---|---|---|
| Severity | Mild | Moderate, disruptive | Severe, disabling |
| Impact on life | Minimal | Affects work, home or relationships | Major impact; relationships, work, safety |
| Main symptoms | Mixed physical and mood | Mixed | Mood symptoms dominate: anger, depression, anxiety |
| Diagnosis | Not a disorder | Clinical, with symptom diary | DSM-5 criteria, confirmed over 2 cycles |
PMDD is recognized as a depressive disorder. It requires at least 5 symptoms, at least one of them a core mood symptom (marked irritability or anger, depressed mood, anxiety or tension, or mood swings), present in most cycles over the past year. Suicidal thoughts can occur in PMDD and should be taken seriously. See premenstrual syndrome for the wider condition.
Why premenstrual irritability happens
Hormone levels are usually normal in people with PMS and PMDD. The problem is the brain's response to the normal rise and fall of estrogen and progesterone after ovulation. A breakdown product of progesterone (allopregnanolone) affects calming GABA receptors, and estrogen changes affect serotonin. Some people are genetically more sensitive to these shifts.
Factors that can make symptoms worse:
- stress and poor sleep
- caffeine and alcohol
- low physical activity
- smoking
- a history of depression, anxiety or trauma
Conditions that can look like PMS
Symptoms that are present all month are not PMS, even if they worsen before periods. This premenstrual exacerbation is common in:
- depression and anxiety disorders
- bipolar disorder
- ADHD
- migraine
- thyroid disorders
Perimenopause can also cause new or more intense premenstrual mood symptoms because hormone swings become larger.
How it is diagnosed
There is no blood test for PMS or PMDD. The key is a daily symptom diary for at least 2 menstrual cycles, rating each symptom and noting your period days. Free apps and printable charts exist, including the Daily Record of Severity of Problems (DRSP). The diagnosis depends on a clear symptom-free week after the period. Your doctor may check thyroid function or screen for depression and anxiety.
How to ease premenstrual tension
Lifestyle steps
- Exercise: 30 minutes of aerobic activity most days reduces mood and physical symptoms.
- Sleep: keep regular sleep and wake times, especially in the luteal phase.
- Cut caffeine and alcohol in the two weeks before your period.
- Eat regularly: small, frequent meals with complex carbohydrates can steady mood and cravings.
- Reduce salt if bloating is a problem.
- Plan ahead: use your tracking to schedule demanding tasks outside the luteal phase where possible, and let close people know.
- Stress management: mindfulness, yoga and breathing exercises.
Supplements
Calcium (1,000 to 1,200 mg a day from diet and supplements) has the best evidence for reducing PMS symptoms. Vitamin B6 and chasteberry (Vitex) have some evidence, but quality varies. Check with a pharmacist or doctor before starting, especially if pregnant or on other medicines.
Therapy
Cognitive behavioral therapy (CBT) helps you manage irritability, anxiety and negative thoughts, and works well alongside other treatments.
Medicines
- SSRIs (such as fluoxetine, sertraline, escitalopram) are the first-line medical treatment for severe PMS and PMDD. They work within days, so many people take them only in the 2 weeks before a period.
- Combined hormonal contraceptives, particularly continuous use or pills containing drospirenone, can reduce symptoms by stopping ovulation.
- Pain relievers such as ibuprofen or naproxen help cramps, headaches and breast pain. Follow the label dose.
- For severe, treatment-resistant PMDD: GnRH analogues to suppress the cycle, with add-back hormone therapy, under specialist care. Surgery to remove the ovaries is a last resort.
Frequently asked questions
Why do I get so angry before my period?
Premenstrual anger is caused by the brain's sensitivity to the normal fall in estrogen and progesterone after ovulation, which affects serotonin and calming GABA signals. Stress, poor sleep, caffeine and alcohol make it worse. If anger is severe or damaging relationships, it may be PMDD, which is treatable.
What is the difference between PMS and PMDD?
PMS includes physical and emotional symptoms that are bothersome but manageable. PMDD is a severe form in which mood symptoms such as rage, depression, anxiety or hopelessness significantly disrupt work, relationships and daily life. PMDD is diagnosed using specific criteria confirmed by symptom tracking over 2 cycles.
How long does premenstrual irritability last?
It usually starts 5 to 14 days before your period and eases within 2 to 3 days after bleeding begins. If mood symptoms last through the week after your period or all month, another condition such as depression or anxiety may be involved.
What helps PMS mood swings naturally?
Regular aerobic exercise, consistent sleep, cutting caffeine and alcohol, eating regular balanced meals, and stress management all help. Calcium supplements have good evidence. Tracking your cycle lets you plan around difficult days. If symptoms remain disruptive, see a doctor about SSRIs or hormonal treatment.
Can PMS cause suicidal thoughts?
Yes, particularly in PMDD. Suicidal thoughts that appear before periods are a medical concern, not something to wait out. Call or text 988 in the US if you are in crisis, and talk to your doctor, as effective treatments are available.
