| Sounds like a really bad explanation that has 0 root in physiology. I have CFS and I had a cardiac stress test and my VO2 max is 20, despite only being 33 years old. It's literally half of what it should be for my age. That's worse than having heart failure. I have a severely impaired lactate threshold and severe exercise intolerance. The other people I know are similar. Autonomic dysfunction has roots in chronic mitochondrial dysfunction. My urine malondialdehyde levels are off the charts high. All this excessive oxidative stress and cellular respiration starts shutting down everywhere. I have been walking miles per day for a long time now trying to alleviate it and I still cannot run or do any intense exercise. Toxic insults, genetic vulnerabilities, antibiotics that induce mitochondrial dysfunction, and many other things cause these insults. I've talked with others that had their mitochondria tested via mass spectroscopy and there's loss of ATP compared to healthy controls and blocked active sites. Our toxic environment and lifestyles and drugs are ruining everyone's physiology. It's really depressing seeing doctors just not remember anything from their schooling and come up with really ignorant and patient-harmful perspectives on chronic disease processes ruining society in 2023. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2680051/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4136529/ https://pubmed.ncbi.nlm.nih.gov/23825301/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6182158/ https://www.sciencedaily.com/releases/2018/10/181001101943.h... |
