Do you dread the two weeks before your period, feeling like a completely different person? If you experience intense mood swings, depression, or anxiety leading up to your period, you may be dealing with more than just PMS. You might have PMDD—Premenstrual Dysphoric Disorder.
Perhaps you know you have PMDD and you’ve noticed it is worse since moving into your 40s?
What is PMDD?
PMDD stands for Premenstrual Dysphoric Disorder. It is similar to PMS but much more severe, characterised by intense mood swings, emotional distress, and physical symptoms that can disrupt daily life. Symptoms typically begin around two weeks before your period and improve a few days after bleeding starts. However, for some women, PMDD symptoms worsen as they transition into perimenopause.
PMDD vs. PMS: What’s the Difference?
PMDD is often called “PMS on steroids” because it’s significantly more intense. While both PMS and PMDD symptoms disappear once the period arrives, PMDD lasts longer and is much more severe. In fact, PMDD is classified as an endocrinological disorder, meaning it is linked to hormone fluctuations.
What Causes PMDD?
Although there is no specific test for PMDD, research suggests that fluctuations in progesterone and oestradiol play a major role. When these hormones drop in the luteal phase (the two weeks before your period), symptoms intensify. PMDD is also believed to involve GABA receptor dysfunction in the brain. GABA is a neurotransmitter that promotes calmness, but in women with PMDD, the receptors that bind to GABA may not function properly, leading to heightened anxiety, depression, and mood swings.
PMDD Symptoms: Do You Have It?
To be diagnosed with PMDD, a woman must experience at least five of the following symptoms to a marked degree over the past 12 months, occurring in the luteal phase and improving after the period starts:
Emotional & Cognitive Symptoms
- Depressed mood – feelings of hopelessness, self-criticism
- Emotional instability – sudden mood swings, increased sensitivity
- Feeling overwhelmed or out of control
- Irritability and anger
- Poor concentration
- Tension and anxiety – feeling constantly on edge
- Increased interpersonal conflicts – picking fights where you normally wouldn’t
- Loss of interest in usual activities – withdrawing from social activities and hobbies
Physical & Behavioural Symptoms
- Changes in appetite – overeating or strong cravings
- Sleep disturbances – either insomnia or excessive sleep
- Extreme fatigue and lethargy
- Breast tenderness, joint or muscle pain, bloating, and weight gain
If these symptoms sound familiar and significantly impact your life, you may have PMDD. You can find the official diagnostic criteria by searching ICD-10 PMDD criteria (in the UK, which stands for International Classification of Diseases, Tenth Revision) or DSM-5 PMDD criteria (in the US, which stands for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition).
Why Does PMDD Feel Worse in Perimenopause?
For some women, PMDD symptoms worsen in their 40s and late 40s due to increased oestrogen fluctuations and declining progesterone levels. When oestrogen is higher in proportion to progesterone, it can raise histamine levels, leading to symptoms like:
- Sensitivity to alcohol, caffeine, or certain foods
- Racing heart after meals
- Increased appetite, cravings, and energy crashes
- Heightened stress and overwhelm
How to Manage PMDD Naturally
Conventional treatment includes oral contraceptive pills (OCP) or SSRIs (antidepressants), which can be lifesaving for some. However, whether or not you take medication, these natural strategies are essential:
Lifestyle Adjustments
- Manage stress in the luteal phase – Reduce commitments, practice self-care, and prioritise rest.
- Avoid alcohol and caffeine – These can worsen PMDD symptoms significantly.
- Increase protein intake – Aim for 100g+ per day to support hormone balance.
- Focus on healthy fats – Ditch refined carbs and sugar; opt for nutrient-dense options like dark chocolate and nut butters.
- Prioritise evening wind-down time – Gentle yoga, relaxing music, and sleep meditations can help regulate the nervous system.
- Get early morning daylight exposure – Helps regulate circadian rhythms and mood.
Supplement Support
- Magnesium glycinate – Supports relaxation and reduces PMS/PMDD symptoms.
- Vitamin B6 (P5P form) – Helps with mood and neurotransmitter function.
- Vitex (Chaste Tree or Agnus Castus) – Especially useful in early perimenopause, as it supports progesterone production and may help reduce PMDD severity. Vitex has been shown in some women to help in the brain. It can help reduce a hormone called prolactin, which can worsen PMDD if it’s too high.
- Body-identical progesterone – Talk to your doctor about bio or body identical progesterone rather than synthetic progestins.
Finding the Right Support
If you feel like PMDD is controlling your life, you’re not alone. Many women only realise they have PMDD after struggling for years with misdiagnosed mood disorders or extreme PMS. By tracking symptoms and making targeted lifestyle changes, you can regain control and start feeling like yourself again.
