Well, this is VERY interesting.
Since going gluten free, my periods have become irregulars - either 20 days, or 35/38 -. Since I was 47 when DX, and 49 now, I thought "perimenopause" and tried to live with it.
Now I think there are all sort of links between hormones and gluten. There is at least one study about celiac disease and hormones which I heard...
this topic is extremely interesting. In the last couple of weeks I've been drinking for breakfast - at home - a tea of the brand KUSMI TEA (French), "Anastasia" wich has bergamot, orange and lemon flavourings. Approx, I've been having light diarroeha and stomach cramps for the same period. Notice that I've been gluten-free and lactose free three months now...
