Depends what the issue is Focus, but with health matters that have a serious effect on quality of life, I find I need to know as much as I can, as only that way can I be sure I'm managing it as well as possible. I also feel a responsibility to gen up so I can get involved in decisions about my care. I think doing that can also help us understand the challenges medics face when treating us. Patients knowing about side effects & risks, that some conditions are very difficult to manage & treatments inadequate, takes some of the pressure off them & can make for a more productive partnership & I think & better progress, with less time wasted going to & fro when what may otherwise be unrealistic expectations are not met.
With long-term conditions there can be so much to learn, not only as regards what received wisdom & research is out there, but from strategies other people adopt. Insights to be gained too, from being vigilant & inquisitive about the way our own body reacts to treatments & to external demands etc.
Medics, especially GPs who have to be jacks of all trades, are just like the rest of us, busy, imperfect, fallible human beings who have bad days & can't be expected to know every detail. So relying on them to sort out every aspect of our health seems unrealistic, when there's also the matter of individual body chemistry in the mix.
But I also realise that many people don't have the time to research exhaustively & there's a real danger of turning up all manner of misleading & erroneous info on the web. It can also be frightening learning about something you've recently been diagnosed with, especially as worst case scenarios are inevitably out there that may never apply to the majority of us. I sometimes have to ease myself in gradually & avoid googling something that might turn up results I'm not ready for! So I understand why some people prefer to hand their care over to the experts & trust in them completely, as my Mum always did.
I do think we can miss out by not being well informed though & that's one of the most valuable things about a forum like this, where so many lovely women are willing to share their experience & knowledge on frustratingly taboo issues in an open, generous way.
