silicon

A grey-black, non-metallic semiconducting element (atomic number 14; atomic weight 28.09) that occurs in nature as silica and silicates, which is present in whole grains and in organ meats. Silicon is integral to semiconductors and solar batteries, and is essential for normal growth and skeletal development in rats and chickens; a silicon deficiency state is not known to exist in humans.

Patient discussion about silicon

Q. Do any of you with FM have silicone breast implants, or have you ever had them? How about saline? My silicone implants expired on the surgeon's shelf before they went in my body. Both implants ruptured and disintegrated within 5 years of implantation. I was diagnosed with FM shortly after 2 surgeries to remove silicone goo. Just wondering if anyone else has made the connection. Thank you!

A. As far as I know several studies failed to prove there is a connection between rupture of breast implants and fibromyalgia, as did the FDA conclude. Indeed I heard about one study that found this connection, but it seemed like a very problematic one.
