What is PMDD?
Premenstrual Dysphoric Disorder (PMDD) is a severe form of premenstrual syndrome (PMS). It causes significant emotional and physical symptoms in the week or two before your period starts and usually improves once your period begins.
Unlike typical PMS, PMDD symptoms are more intense and can seriously affect your daily life, relationships, and mental health.
What are the symptoms of PMDD?
Emotional symptoms may include:
- Severe mood swings
- Irritability or anger
- Anxiety or panic attacks
- Feeling very low or hopeless
- Trouble concentrating
- Feeling overwhelmed or out of control
Physical symptoms may include:
- Bloating
- Breast tenderness
- Headaches
- Fatigue
- Sleep problems
- Joint or muscle pain
- Appetite changes or food cravings
These symptoms typically appear after ovulation (mid-cycle) and ease within a few days after your period starts.
What causes PMDD?
The exact cause isn’t fully understood, but PMDD is thought to be related to an abnormal reaction to hormonal changes, particularly sensitivity to progesterone after ovulation. It’s not caused by a hormone imbalance, but by how your brain responds to normal hormonal fluctuations.
Some people with PMDD may also be more prone to mood disorders like depression or anxiety.
How is PMDD diagnosed?
Diagnosis usually involves:
- Tracking your symptoms daily for at least two menstrual cycles using a symptom diary or app
- Confirming that symptoms are present only during the premenstrual phase and improve after your period starts
There’s no specific blood test for PMDD.
How is PMDD treated?
Treatment depends on how severe your symptoms are and may include:
Lifestyle changes:
- Regular exercise
- Balanced diet and reducing caffeine, sugar, and alcohol
- Good sleep habits
- Stress management (e.g., mindfulness, yoga)
Medications:
- SSRIs (Selective Serotonin Reuptake Inhibitors): Antidepressants that can be taken daily or only during the second half of the cycle
- Hormonal treatments: Like the contraceptive pill, GnRH analogues, or hormonal IUDs to stop ovulation
- Pain relief: For physical symptoms like cramps or breast pain
Other options:
- Cognitive behavioural therapy (CBT)
- Supplements (e.g., calcium, vitamin B6 – talk to a doctor first)
In very severe cases where other treatments haven’t worked, surgical options (like removing the ovaries) may be considered – though this is rare.
When should I seek help?
You should talk to your healthcare provider if:
- Your mood or physical symptoms feel overwhelming
- PMDD is affecting your work, relationships, or quality of life
- You have thoughts of self-harm or feel unable to cope
