Hi,I'm wondering if the lightheadedness is partly an oxygen delivery problem. I was over on the "Memory" board here and they are talking about gingko biloba, etc.. This is an anticoagulant that helps with oxygen delivery to the brain.
I have experienced this, and dizziness, and a feeling like I'm shutting down, and for me it's been a hypercoagulation problem. I've been tested for it and am currently on prescription anticoagulants until my blood is normal, but even so, if I become ill or experience undue stress, I'll have to go get tested again because this tends to cause the blood to thicken for me - I have a genetic defect with coagulation. FYI, 15% of the caucasian North American population likely has a coagulation defect, but it isn't going to be catastrophic for most (as it nearly was for me). In most cases there will be a slow accumulation of thickened deposits in the blood, appearing to be part of the aging process. If anyone is interested in where I got this test done, email me.
My understanding is that estrogen can increase the clotting cascade, so I wonder if an imbalance here can cause a person to be afflicted this way.
Nonprescription anticoagulants that I'm aware of are:grape seed extract (a bioflavinoid)garlicbromelain(don't use if allergic to bee stings)gingko bilobaaspirin (use with care - too much can make your blood too thin - or irritate the stomach - there are smaller tablets available)
Vasodilators can help too - relaxing the vascular system so more blood can move around:grape seed extractniacin (not the no flush kind - it's hard on your liver - and start with a low dose - a niacin flush is warm and itchy and probably would be horrendous if it happened at the same time as a hot flash! On the "Ask Dr. Weil" website he says "The niacin flush is the result of dilation of blood vessels in the skin due to the vitamin's effect on arteries and the nerves that regulate them. It is a harmless reaction and may even be of benefit in some people with problems of blood circulation. "
There is an OTC available in Europe, Piracetam, that helps the brain better use available oxygen. I get it from a friend in Europe (legally, there is an FDA pilot program that allows this if it's an OTC medication and if it's just for your own use)
