Yep, its a blood thinner and too much of them and you tend to get leaky blood vessels.

You see there are two types of strokes those caused by clots and those caused by bleeding due to leakage.

In the clot type stuff accumulates on the walls of the vessel which becomes inflamed and blood begins to clump with the help of fibrin eventually forms a clot that either plugs or almost plugs up the vessel... then just like your pipes bursting in the winter pressure builds and then boom a blood explosion in your head, if you have high BP or are taking drugs that negatively affect BP this process is speed up and more likely to occur just ask rfarris.

In the leaky blood vessel type of stroke your blood gets so watery that it basically slips between the cracks of smaller vessels such as capillaries and spreads out into the surrounding tissues again with a high BP or BP increasing drugs this process is magnified and speeded up. Furthermore due to the fact that the blood is thinned the initial infiltration of blood into the tissue is not halted by a prompt clot so it continues to spread and the result is a stroke just like the explosive kind, maybe less dramatic but still very very bad.

Granted the second scenerio happening just because of fish oil is probably not very likely but if you are taking other blood thinners especially prescription ones then adding in things like Fish Oil, Gingko, Aspirin, Garlic and others might be a problem

Edward, what lab work would you want to see in order to reduce the likelihood of the leaky vessel type of stroke? Just some sort of basic clotting time? I'm guessing there's more sophisticated stuff... Of the two types of strokes, is one a lot more common than the other?

Isn't an ischemic stroke one in which there is a blockage? Seems one would expect more of the hemorrhagic variety with Omega 3. The Omega 3 could be causing irregular heartbeats, which can cause an ischemic stroke, right?

Wonder how taking low dose aspirin would affect those studies, whether it would ameliorate or eliminate the risk.

Apparently fish oils are protective of arrhythmias.

The detrimental effects of high fish intake and fish oils on
hemorrhagic strokes are understandable due to the blood
thinning effects, but I am still puzzled as to their adverse
effects on ischemic strokes as well.

I have written to the Spanish author, Caicoya, of the first study
above, but he no longer uses that mail.

You would want to look at (PT/INR) basically a test to see how long it takes for your blood to clot (PT time) then converts it to a standardized unit INR. You could get fancy tests for various clotting factors but the end result is the same thing and a simple PT/INR will give you the same results. http://www.labtestso...es/pt/test.html

Normal PT time is 11.0-13.0 seconds, normal INR is 0.9-1.2. If you are on anticoagulant therapy (such as post surgical to prevent clots) therapeutic INR is usually 2.0-3.0. An INR of 6.0 or greater is a critical value, meaning get yourself to a hospital but try not to exercise or get stressed out on the way or you might bleed.

Personally I would be ok walking around with an INR of 0.9-2.0 anything higher and I would be afraid to do high intensity exercise or take any sort of CNS stimulant.

high blood pressure (natural or caused by exercise, stress, exertion or drugs) + very thin blood = bad combo.... add in weak blood vessels, narrowed arteries or inflammation and the problems get worse.

edit: sorry for the late response I had forgotten about this thread
