Yes, because medicine is ultimately a customer-serving profession, there will be plenty of people saying the things that people want to hear because they are paid to retain customers and people elevate things that are similar to what they want to hear.
People are very uncomfortable with the mental, hence it is now popular to hear very mechanistic explanations of why someone is depressed, etc. about 'brain chemical imbalance' because it makes someone feel less like it is something wrong with who they are as a person (the mind-body dualism is still very present for most people in Western cultures). Of course, ultimately everything (including the functioning of our mind) is mechanistic, but people seem to be more comfortable with very mechanistically couched explanations as compared to 'something is wrong with my mind!' even when the implications aren't all so different.
1) damaged endothelium with possible microclots clogging up small vessels
2) spike protein reservoir likely causing cellular-level iron deficit (anemia)
3) mitochondrial dysfunction
Some recent research even shows brain hypoperfusion and different levels of oxygen in each hemisphere!
Now ignoring these factors is in my opinion lazy science and a convenient way for medical professionals to state "it's not my problem, go somewhere else, I just want my regular routine without any complications. Go see a shrink".
I'm going to suggest that with this intense pace this might have happened one way or another. Take it from someone who has been there.
When we push too hard for too long, and ignore our bodies and minds pleas for rest, at some point the body is going to put the brakes on us.
I don't think this is necessarily COVID specific, my speculation is that long COVID is the kernel around which the fatigue episode crystallised, and thatif it hadn't been COVID it would have been something else.
I later felt that this focus on this 'replace lost nutrients' approach, while it might have had some merit in the acute phase, also kept some people in denial of the factors which led them to their health crises.
Any nutrient you take to excess will be downregulated by one of these thousands of processes shown here: https://external-preview.redd.it/Yepk20IXyppuST6erisGCPg716V...
