It is worth asking what the claim would look like if it were false.

Adding the part of the answer the thread has not reached. The distinction that resolves most of these threads is between what is true on average and what is true for one person. Both are real; they answer different questions and get quoted as if they were the same one.

The figures, for anyone assembling their own picture. Worth stating the units and the reference range whenever you post a number here. A large fraction of the apparent disagreement in these threads is two people using different units and both being right.

Ask again with the specifics and you will get a better answer than this one.

Following on from LindaRN_retired — and this may be the naive question:

How would you tell the difference between that and the alternative explanation?

I read this differently from hank_denver, on substance rather than tone. Pushing back on the anecdote-stacking. Twenty people reporting the same thing is twenty samples from the same self-selected pool, not twenty independent confirmations.

No disagreement, though the timescale matters more than the mechanism here. Most of what looks like a difference in kind turns out to be a difference in how long somebody waited.
