firewatcher Posted January 17, 2009 Report Share Posted January 17, 2009 Just found this:http://www.circ.ahajournals.org/cgi/content/full/109/18/e217Dr Cheng is quite right in his comments on our article1 aboutthe value of simple measures in syncope. It is remarkable howsimple lifestyle changes can elicit such dramatic effects inautonomic disorders and especially in autonomic failure.2 Standingmay lower blood pressure more than 50 mm Hg in suchpatients, whereas lying down may take a patient?s blood pressureup into the hypertensive range. The ingestion of food may lowerblood pressure 30 mm Hg while the ingestion of 16 ounces of tapwater may raise blood pressure by 40 mm Hg.3 Hyperventilationmay lower blood pressure by 30 mm Hg, whereas hypoventilationmay raise pressure 25 mm Hg.4 Exercise and straining, suchas the Valsalva maneuver, significantly lower blood pressure,whereas immersion in water and the use of abdominal bindingare pressor.5 Another remarkable effect is that conditions thatelicit fever in normal individuals may more prominently lowerblood pressure in autonomic failure patients and have less effecton temperature elevation. These observations indicate that patientswith autonomic disorders have a large armamentarium oftherapeutic maneuvers at their disposal. Careful application ofthese maneuvers can greatly enhance their ability to tolerate theirillness.Chih-Cherng Lu, MDChe-Se Tung, MD, PhDNational Defense Medical CenterTaipei, Taiwan, ROCAndr?

janiedelite Posted January 18, 2009 Report Share Posted January 18, 2009 Wow Firewatcher, you come up with great research. Thanks for posting! Janie Quote Link to comment Share on other sites More sharing options...
jjpots Posted January 18, 2009 Report Share Posted January 18, 2009 O.k., maybe I have a little brain fog but is that saying that people with autonomic dysfunction my not get a fever as easily???Jen Quote Link to comment Share on other sites More sharing options...
firewatcher Posted January 18, 2009 Author Report Share Posted January 18, 2009 O.k., maybe I have a little brain fog but is that saying that people with autonomic dysfunction my not get a fever as easily???JenThat's how I read it also. It would explain why I never had a fever even when I test positive for strep. Quote Link to comment Share on other sites More sharing options...
Rachel Posted January 18, 2009 Report Share Posted January 18, 2009 It actually says autonomic failure, which is different from autonomic dysfunction. Isn't autonomic failure the same as or similar to pure autonomic failure? PAF is progressive, but autonomic dysfunction isn't. POTS and NCS aren't life threatening, but PAF is.Rachel Quote Link to comment Share on other sites More sharing options...

Katja Posted January 19, 2009 Report Share Posted January 19, 2009 since they don't cite it, I'd guess that it's one of their own observations. Quote Link to comment Share on other sites More sharing options...
jjb Posted January 19, 2009 Report Share Posted January 19, 2009 Can any of you figure out which article that little gem of information is from? I can't find it in the reference articles. Came from this article:Simple Self-Help Maneuvers Are Effective in Aborting Vasovagal SyncopeInteresting about the temp issue. I am the opposite and in fact nutty fevers are part of my dysautonomia.I went a long time w/ having daily fevers ave 101 to 102 and as high as 105. I'd seen many docs but no one could figure it out. years later of course I'd find it it is just another one of my autonomic quirks.W/ illness, I get fevers easily.
