Premenstrual syndrome (PMS) refers to a range of physical and emotional symptoms that occur in the days leading up to a woman’s period. Its severity varies considerably from one woman to another and can change over the course of a woman’s life. The most common symptoms include:
When emotional symptoms become severe enough to significantly disrupt daily functioning, the condition is referred to as premenstrual dysphoric disorder (PMDD), a more intense form of PMS requiring specialized care.
The exact mechanisms remain only partially understood, but hormonal fluctuations during the menstrual cycle play a central role. The drop in progesterone and estrogen during the second phase of the cycle affects brain neurotransmitters, particularly serotonin, which is involved in regulating mood, sleep, and appetite. Individual hormonal sensitivity, a deficiency in magnesium or vitamin B6, and a predisposition to anxiety can amplify the symptoms. Lifestyle factors such as chronic stress, lack of sleep, and a diet high in refined sugars also exacerbate the symptoms. Thyroid disorders can mimic certain signs of PMS and must be ruled out during the initial evaluation. Keeping a menstrual diary for two to three cycles facilitates diagnosis by helping to identify recurring patterns.
Several micronutrients have been shown to be effective in reducing symptoms:
These supplements are part of a holistic approach and are not a substitute for medical advice when symptoms are severe or debilitating.
Chasteberry (Vitex agnus-castus) is the most well-documented herb for PMS. It acts on the pituitary axis and helps rebalance the progesterone-to-estrogen ratio, notably reducing breast tenderness and mood swings. It must be used over several cycles to achieve a lasting effect. Other adaptogenic herbs can support emotional balance during the premenstrual period, always under the guidance of a healthcare professional. It is important to note that chasteberry is contraindicated during pregnancy, while breastfeeding, and when taking hormonal or dopaminergic treatments.
Diet directly influences the severity of PMS. Here are some practical adjustments:
Regular physical activity releases endorphins that naturally counteract the effects of hormonal fluctuations on mood.
For some women, PMS improves with age and disappears after menopause, when hormonal fluctuations cease. For others, it may intensify during perimenopause. Monitoring the progression of your symptoms over several cycles and recording them in a journal helps you adjust your management strategies and identify when medical follow-up is necessary.
