I'll re-post this here for those interested with a little bit of an edit. I've been yapping for some time now about
the hormone side of things...
You might find this a good read for those interested in IBS and hormones... Far more women have IBS then men etc
www.weillcornell.org/pdf/ibs/Frissora_-_Practical_GastroHORMONES.pdf It's about
Hormones and GI Disorders in Women.
Here is an excerpt from it:
------
Hormonal Influences on the Gastrointestinal Tract and Irritable Bowel Syndrome
Recent research has uncovered a potential role for abnormal serotonin expression and/or signaling in IBS and other GI disorders. The potential effect of sex hormones such as estrogen and progesterone on serotonin remains to be elucidated. However, the importance of serotonin and its receptors, as well as serotonin polymorphisms, in predicting response to treatment is an area of interest.
-------
Also, this is important: during pregnancy the dominant type of estrogen is estriol circulating -estriol is 80% less potent than estridiol (which is dominant during reproductive years).
Because estriol is less potent, it obviously has the potential to effect or cause abnormal serotonin signaling once a female becomes pregnant - hence the sudden on-set of symptoms.
There is much information stating the effects of Estrogen on Serotonin/Dopamine etc. And there are three types of Estrogen in women - estrone, estradiol and estriol. At certain times in female bodies one type is more dominant than than the others (i.e during menstrual cycle, after menopause etc). So things can get screwy when one type is more dominant than the other.
For sure there is something to the Hormonal side and the effects/symptoms. I came across this all a loooong time ago when looking at some other autoimmune diseases and the effects that air pollution has on them for my line of work (air quality). I had to make a power point presentation on it.
Statistically women are as much as 80% more likely to come down with one or more autoimmune conditions and as many as 1 in 4 will in fact most likely after menopause. There's a very strong very link suggested between air pollution and autoimmune disease (Arthritis, Lupus etc) - and wonky hormones perhaps explain why the dominance in women.
Also when you think about
Prednisone... Almost Everyone responds to their initial Pred course, but then after tapering or after multiple courses it stops working... After time one (dopamine) can start to further deplete the other (serotonin) and visa-versa. Pred is a full on hormonal drug. It mimics the effects of hormones in your body.
Males are also effected by hormones -just as women, but to a lesser extent in some cases in regards to estrogen etc.
Anyway - there's lots and lots of information pointing to wonky hormones at the root.
