PMDD symptoms can be severe, distressing and disruptive to everyday life. While many women experience mild premenstrual symptoms before their period, Premenstrual Dysphoric Disorder (PMDD) is a much more significant condition that affects mood, behaviour and physical wellbeing.
PMDD is a recognised medical disorder in which symptoms occur during the luteal phase of the menstrual cycle (the one to two weeks before menstruation) and improve shortly after a period begins.
Although only around 3–8% of menstruating women are thought to experience PMDD, the condition is often underdiagnosed. Many people struggle for years before recognising that their symptoms follow a cyclical hormonal pattern.
What Is Premenstrual Dysphoric Disorder?
Premenstrual Dysphoric Disorder is considered a severe form of premenstrual syndrome (PMS), but the psychological symptoms are far more intense.
Unlike typical PMS, PMDD symptoms significantly affect daily functioning, relationships and work.
The key feature of PMDD is its cyclical pattern:
- Symptoms appear after ovulation
- Symptoms worsen in the days before a period
- Symptoms resolve soon after menstruation begins
- There is usually a symptom-free phase after the period
Tracking this pattern is crucial in diagnosing PMDD.
Why PMDD Symptoms Occur
Interestingly, PMDD symptoms are not caused by abnormal hormone levels.
Instead, research suggests that people with PMDD have an increased sensitivity to normal hormonal changes during the menstrual cycle.
After ovulation, progesterone levels rise and the body produces a hormone metabolite called allopregnanolone. This chemical interacts with receptors in the brain that regulate mood and anxiety.
In individuals with PMDD, the brain appears to respond differently to these hormonal signals, affecting neurotransmitters such as serotonin.
As a result, even normal hormonal changes can trigger significant mood and behavioural symptoms.
Why PMDD Symptoms Can Worsen in Perimenopause
Many women notice that PMDD symptoms worsen during perimenopause.
Perimenopause is the stage leading up to menopause and is characterised by more unpredictable hormone fluctuations.
Common hormonal changes during this stage include:
- irregular ovulation
- fluctuating oestrogen levels
- inconsistent progesterone production
These changes can amplify the brain’s response to hormonal shifts, making PMDD symptoms more noticeable or more severe.
Some women report experiencing PMDD symptoms for the first time in their 40s, when hormonal variability becomes more pronounced.
Risk Factors for Developing PMDD
Not everyone develops PMDD, and certain factors appear to increase the risk.
These include:
- personal history of depression or anxiety
- previous postnatal depression
- family history of mood disorders
- history of PMS
- high levels of stress
- genetic susceptibility
However, PMDD symptoms can occur even in individuals with no previous mental health concerns.
Common PMDD Symptoms
PMDD symptoms typically occur in the week or two before menstruation and improve shortly after the period begins.
The most prominent symptoms tend to be emotional or psychological.
Emotional PMDD Symptoms
- severe irritability or anger
- sudden mood swings
- feelings of depression
- anxiety or tension
- feeling overwhelmed
- loss of interest in usual activities
- difficulty concentrating
Many patients describe feeling like “a completely different person” during this phase of the cycle.
Physical PMDD Symptoms
In addition to emotional symptoms, people may experience:
- fatigue
- breast tenderness
- headaches
- bloating
- joint or muscle pain
- sleep disturbance
- changes in appetite
For a diagnosis of PMDD, these symptoms must significantly interfere with daily functioning.
How PMDD Symptoms Are Diagnosed
Diagnosing PMDD usually involves tracking symptoms over at least two menstrual cycles.
This helps confirm:
- the cyclical nature of symptoms
- their timing in relation to ovulation
- improvement after menstruation
One of the most commonly used tools to diagnose PMDD is the Daily Record of Severity of Problems (DRSP). This validated questionnaire allows patients to track symptoms daily across at least two menstrual cycles to confirm the cyclical pattern typical of PMDD.
Symptom tracking can also help differentiate PMDD from other mood disorders.
Treatment Options for PMDD Symptoms
Fortunately, there are several treatments available for managing PMDD symptoms. Treatment will depend on symptom severity and individual preference.
Often, a combination approach works best.
Hormonal Treatments for PMDD Symptoms
Hormonal treatments aim to stabilise hormonal fluctuations or suppress ovulation.
Options may include:
Combined Oral Contraceptive Pill
Some combined contraceptive pills can help reduce PMDD symptoms by suppressing ovulation and stabilising hormone levels.
Continuous pill use (skipping pill-free intervals) may also help some individuals.
Hormone Therapy in Perimenopause
For women experiencing PMDD during perimenopause, stabilising hormones with transdermal oestrogen and progesterone therapy may help improve symptoms.
Ovulation Suppression
In severe cases, specialist treatments that suppress ovulation completely may be considered.
Non-Hormonal Treatments for PMDD Symptoms
Antidepressant Medication (SSRIs)
Selective serotonin reuptake inhibitors (SSRIs) are considered first-line treatment for moderate to severe PMDD symptoms.
Interestingly, SSRIs can be taken either:
- continuously
- or only during the luteal phase of the cycle
Both approaches can be effective.
Cognitive Behavioural Therapy (CBT)
Psychological therapies can help individuals develop strategies for managing mood changes and emotional distress associated with PMDD.
CBT may be particularly helpful alongside medical treatment.
Lifestyle Measures
Lifestyle changes alone rarely eliminate symptoms completely, but can help support overall wellbeing.
Helpful measures may include:
- stress management techniques
- regular exercise
- good sleep hygiene
- reducing alcohol intake

When to Seek Medical Advice
You should consider seeking medical advice if:
- symptoms significantly affect daily life
- symptoms feel severe or overwhelming
- symptoms worsen during perimenopause
- you suspect PMDD but have never been assessed
Accurate diagnosis and appropriate treatment can make a substantial difference to quality of life.
In Summary
PMDD symptoms are caused by an increased sensitivity to normal hormonal changes during the menstrual cycle. For some individuals, these symptoms can significantly impact emotional wellbeing, relationships and day-to-day functioning.
Although PMDD can be challenging, effective treatments are available. Understanding the cyclical pattern of symptoms and seeking appropriate support can help individuals regain control and improve their overall wellbeing.
Frequently Asked Questions About PMDD
1. How are PMDD symptoms different from PMS?
PMDD symptoms are much more severe than typical premenstrual syndrome (PMS). While PMS may cause mild irritability or bloating, PMDD symptoms often include significant mood changes such as depression, anxiety, anger or feeling overwhelmed. These symptoms can interfere with work, relationships and daily life, and they usually follow a clear cyclical pattern linked to the menstrual cycle.
2. When do PMDD symptoms usually occur?
PMDD symptoms typically occur during the luteal phase of the menstrual cycle, which is the one to two weeks before a period begins. Symptoms usually improve or resolve shortly after menstruation starts, and many people experience a symptom-free period in the weeks after their period.
3. Can PMDD symptoms start during perimenopause?
Yes, some people notice PMDD symptoms for the first time during perimenopause. This stage of life is characterised by more unpredictable hormonal fluctuations, which can increase sensitivity to hormonal changes and trigger symptoms similar to PMDD or worsen existing symptoms.
4. What treatments help manage PMDD symptoms?
Several treatments can help manage PMDD symptoms, depending on severity. These may include hormonal treatments such as certain contraceptive pills or hormone therapy, as well as non-hormonal treatments like selective serotonin reuptake inhibitors (SSRIs). Psychological therapies such as cognitive behavioural therapy (CBT) and lifestyle measures can also be helpful as part of a broader treatment plan.
5. How can I track PMDD symptoms?
Tracking PMDD symptoms over several menstrual cycles is often recommended to confirm the diagnosis. Many people use menstrual cycle tracking apps to monitor mood changes, physical symptoms and cycle timing. This information can help identify patterns and support discussions with a healthcare professional.
6. Can PMDD be cured?
PMDD cannot always be permanently cured, but it can often be managed very effectively with the right treatment and support. Many people find that their symptoms improve significantly with hormone treatment, SSRIs, lifestyle adjustments, or a combination approach. For some, symptoms also settle once periods stop after menopause. The most important step is getting the diagnosis right and finding a treatment plan that is tailored to your symptoms and stage of life.
