I've got to say that I have personally been told in the past by medical 'authorities' that this or that problem was idiopathic. One example was about about eight years ago when I was treated for a prolactinoma. I was told at the time that about 20% of the population has this problem and no one knows why. I'm sorry but that's pathetic. Ironically, after discovering the work of Peat it all made perfect sense. I also experienced melasma (a pigment disorder) around the same time as well as PCOS and endometriosis resulting in a partial hysterectomy all by the age of 36! As an aside I noticed that while on bromocriptine for the prolactinoma the pigment disorder resolved. This all probably could have been prevented or minimized had I not followed conventional wisdom. It's really a shame that peoples lives are being effected to varying degrees and when they seek help from medical authorities (conventional or alternative) they are often told that the problems origin is unknown! If you start reading Peats work it soon becomes obvious that this human body isn't so mysterious after all! I can't believe people accept that type of explanation and I was one of them. Thanks for letting me RANT. I feel so much better now. :2cents
