I used to suffer very badly from PMS. My cycle was so erratic that I seemed to have symptoms three out of four weeks. I got to a point of desperation and rang a service run at the time by Dr Maryon Stewart here in the UK. She has written a few books on PMS, menopause and women's health in general. I paid for phone consultations with her. She put me on a strict diet that was essentially gluten free and no caffeine. She also told me to eat more oily fish, prescribed a cartload of supplements and told me to up my game on the exercise front. I was desperate at that time. She explained that my symptoms stemmed from an intolerance to wheat and eventually I reintroduced rye, barley and oats back into my diet. I felt better and most symptoms subsided over the next few months. I lost weight and had more energy but this was to be expected because I had stopped eating junk and increased my physical activity. I eventually reintroduced wheat and 20 years on eat bread etc but try not to go overboard. It's just common sense. So is getting as much exercise as possible.
I absolutely sailed through menopause even though I had previously feared I would have a tough time due to my PMS history. By this point I was aware of the mind body connection.
In hindsight I feel that it was my erratic life that caused the hormonal imbalance and subsequent irregular cycle. Once I had been through the above programme, my cycle was pretty much bang on regular. Was the diet thing a placebo? I think so. Can't prove it but here was this leading expert on women's health, a published author, telling me she could cure me and so she did. I had less felt less trepidation and fear so was more relaxed. That was what put paid to the symptoms.
There were to be a few more incidents that provided proof there was a definite link between my mental state and my hormones. The most recent one was following my daughter's car accident I was in such a state of shock that 14 months post menopause, I had a period. It was approximately 3 weeks after the accident. I'm not one to consult Dr Google but I had a peek on this occasion. Having a period 6 month or more post menopause may be a cause for concern and it was suggested to see a doctor. However, I noted that at the top of the list of known causes was 'non-gynochological trauma'. I certainly qualified for that so didn't give it another thought. Never happened a second time.
