Differentiating ‘normal menstrual changes’  from PMS (Premenstrual Syndrome) ‘symptoms’ is a big problem for patients, clinicians, and researchers . There is no biological test that can be used to diagnose PMS and most symptoms rely on patient description e.g. pain, metabolic, or mood-related changes .
In fact, the latest clinical guidelines on PMS focus on the timing and severity of (apparently) ‘any’ symptoms:
“It is the timing, rather than the types of symptoms, and the degree of impact on daily activity that supports a diagnosis of PMS. The character of symptoms in an individual patient does not influence the diagnosis… There is no limit on the type or number of symptoms experienced” .
However, without a list of the most common cyclical symptoms, or knowing how to differentiate between symptoms and ‘normal changes’, it’s possible for patients and clinicians to overlook the role that the menstrual cycle may play in their health…
So, here are some useful lists to help you and your doctor decide what’s going on !
The most common PMS ‘symptoms’
(Cyclical changes that are so severe that they disrupt daily life and/ or require medical support- affecting approx. 3–8% of the menstruating population only )
Normal ‘menstrual changes’
(Cyclical changes that do not disrupt daily life or typically require medical support)
- Mild forms of any of the ‘PMS symptoms’ listed above
- Restlessness/ pins and needles (Note- this can also be a sign of anaemia)
- Mild acne
- Water retention
- Tearfulness — happy and sad
- Libido changes — high and low
- Concentration level changes
- Mood changes — happy and sad
- Energy level changes — high and low
- Clumsiness — usually after poor sleep
- Body temperature changes
The most common menstrual cycle triggered/ worsened conditions
(Note: These are nearly all female-prevalent conditions)
- Irritable Bowel Syndrome (IBS) 
- Migraine 
- Sleep disorders e.g. insomnia (not enough) , or hypersomnia (too much) 
- Endometriosis 
- Asthma 
- Iron deficiency anaemia 
- Skin conditions e.g. acne , or eczema 
- PMDD (Premenstrual Dysphoric Disorder) 
- Anxiety 
- Depression 
- Diabetes Mellitus (type II) 
- Chronic Fatigue Syndrome (CFS)/ Myalgic Encephalomyelitis (ME) 
- Epilepsy 
- Auto-immune conditions e.g. Multiple Sclerosis (MS) , Systemic Lupus Erythematosus (SLE) , Rheumatoid Arthritis , or Fibromyalgia .

 ‘Menstrual Changes’ were first described by the late, great Mary Brown Parlee (1943–2018) in 1973, as a means to differentiate the positive and non-medical changes associated with the menstrual cycle, in an effort to counter the prevailing (incorrect) assumption that the cycle was a form of illness in itself… Which can still happen all too easily, these days!
