PMS can be caused by many different factors. Stress is often a major and common contributing cause. Even for those who don’t feel stressed, stress can still exist in the form of poor diet, too much coffee or energy drinks, smoking, intense exercise, or emotional stress from difficult relationships or work life.
Caffeine creates stress in the body, and stress is actually one of the biggest reasons behind menstrual cycle problems — because the body wants to save energy when there is no calm or balance in life. That’s when issues with the cycle and hormone balance can quickly appear.
In addition to stress, there are other causes to consider. For example, whether we get enough vitamins and minerals from our food. PMS can be linked to vitamin deficiency, chemicals, unresolved trauma, or emotional aspects from childhood and growing up that create stress, or physical imbalances in our hormones and menstrual cycle.
