Hi there Bec.
I guess it is really important fo ryou to just concentrate on living the healthy life you have and try not to focus too much on what might happen. But taking hte proactive approach will definately help you reduce risk, definately.
I have Endo. Had it burnt off very early on 8-9 years ago. Didn't know the true effect of havin git gone for a while as i was recovering form the laporotomy and cyct removal. PCOS and Endo are quite strongly linked but like the others girls have said we all seem to have different symptoms and severity.
I agree with Bellmarks, and the Estrogen, Insulin and Progesterone links. There seems to be an absense or lack of these diseases and syndromes in Countries where woman are pregnant more and therefore have fewer cycles subject to estrogen and more pregnancies and progesterone.
I do now that they have linked Endo to having similar characteristics to Auto Immune diseases where the body is attacking itself to some extent.
Some of the things we need to avoid...with not a lot of solid proof, just research and gut instinct that unrefined and unadulterated is always best....are
High sugar diets, i like you do have a love for sugar.
We need to eat regualrly allowing our insulin to stay more balanced.(every 2 hours min)

And i try to avoid the estrogen enhancing foods and substances.
Some of these are
-Soya Products
-Dioxins..produced in the manufacturing and burning of plastics...so keep plastic out of the microwave, actually keep away from the microwave itself! No cling film( Glad wrap for the aussies)
-Fragrances have an estrogen effect on the body, so get rid of heavily perfumed detergents and airfreshners etc etc
A really good book to read is called...Hormone Disrupters. If you need the author let me know and i can get it for you.
As for pain relief, i don't cope too well. I try to keep as natural as possible but lately i have gone back to using Naprogesic (got a huge supply when last home) to just help. It is a bit taxing dealing wiht that along side not falling pregnant. But usually it is time off and hot water bottles, baths.

Mum got me onto a Chinese Herb that i am about to try which has had amazing results for some woman with both conditions. It is called Peony. I have yet to try it. Othere chinese meds that have been good are Poria and Licorice and Cinnamon. I have not reacted well to Cramp bark and Wild Yam. A bit halucinogenic for me,,was not pleasant.

Hope this helps. There are also a lot of emotion links to these conditions. Excercise is so important too as good circulation helps your body heal itself better and faster.

Sorry Bec, i do go on. By the way the Moon cup is goign really well. Thanks
Hippy Mum
