I have been able to significantly reduce my flu-like feelings. They are very mild compared to a year ago. I did it through treating dysbiosis, leaky gut and mitochondrial dysfunction.
Those are the only changes I've made in the last year. I also learned, just in the last 2-3 weeks, that high dose coq10 (4-500mg a day) has either stopped or greatly reduced my flu-like flares. They felt just like the flu but were not and would last 4-5 days, often putting me in bed for those days.
I use to feel the flu-like feelings most of the day, to varying degrees. Now I feel them mildly a couple of times a day and they don't last very long.
It seems to me it's the mitochondrial dysfunction that causes my flu-like flares and probably my off and on mild flu-like symptoms now.
That's why the coq10 stopped the flares. I believe it's my gut though, that is causing the mitochondrial dysfunction through immune system activation and oxidative stress.
I feel like I am slowly getting my life back!
