Many people here have or are experiencing stress and/or anxiety both of which are known to cause and be caused by hormone fluctuation. Even though some fluctuation is normal, as you said, levels can get out of whack. I went, early on, to an specialist on the recommendation of my GP but she said that blood tests and an exam can usually pick up serious hormone irregularities. However, current research is showing that abnormally high levels of cortisol (usually present and fluctuates like other hormones) in people and animals who are under stress and the findings have some interest to us bcfs/bfs-ers. Higher levels over longer times lower immunity and there are lots of little problems that also creep in like weight, control, and sleep problems. Cortisol is peaked during stress/exercise to help the body spring into action but our bodies and minds do not always know the different between stress (look out it's a saber tooth!) and stress (my job is threatened, I am worried abut my health, I'm anxious about a test/finances, etc). Some reading about 'stress hormones' is available in books and research by Sapolsky if you are interested. Oh, guys, one paper I just found said they discovered an inverse relationship of cortisol and testosterone levels.IMO we have to remember to see ourselves as not minds and bodies but a well-integrated unit. What you think affects your body and what you do physically affects your mind - it is how we are made even though we are not often aware of this integration. Only recently with the explosion of medical testing have the healers introduced this dichotomy of mind and/vs body rather than seeing individuals as a mind-body system. Some people are getting back to it or being forced back to it by research.Ladies, I know there used to be many that would try to ask us, while carrying children, to remain calm, eat well and relax, listen to certain music to affect a healthy child. I guess you'd have to go to a naturalist gyn to get this stuff now as it is all about ultrasounds etc. Is that your experience?What do you think? Is this something you can accept, or something that you think is hooey? What is the basis for your reasoning and how can this help you to heal from this syndrome? It seems many here do not accept this as it does require some taking of responsibility - even if it is a cascade effect that causes this syndrome it puts the individual in the driver's seat for healing. It can't be that it just happened to you like a lightening strike, or that you will go find a doctor that 'cures' you; if you accept this thinking you have more of a role to play.
