Sleep apnea is like knee pain in that loosing significant weight either makes a huge difference, or does nothing. Unfortunately, if it doesn’t work for you people will still constantly bring it up.
As someone who struggles with weight and chronic conditions.
There are low hanging fruit.
Dropping weight, removing processed foods, exercise are your bare minimum of what everyone should try for solving Medical problems.
Now a lot of problems can be solved this way. Just not everything.
I suffered exercise intolerance for decades. No mater how hard I tried I would need two weeks of recovery after any work out.
Turned out I had underlying problems that none of the what I mentioned above were going to fix.
However I still feel strongly that if I’m going to complain to a doctor, I should be doing my part with diet and exercise.
