Apnea and snoring went away for me when I quit sugar and carbs. Losing weight and particularly inflammation does wonders for snoring. Now I require a lot less sleep too.
Sleep quality is one of the big three life improvements I found from going low carb/high fat. The other two the end of acid reflux and blood pressure normalized.
Too bad more people can’t figure out the sugar and carbs are making them miserable and killing them. Of course drug companies couldn’t sell statins if people figured that out.
The VA is pretty focused on Sleep Apnea because it is more present proportionally in veterans than the general population.
A marker for Sleep Apnea is a build up of red blood cell count. The lessened oxygen during sleep forces the body to create more red blood cells to transport oxygen. This does thicken the blood and predispose for clots.
This study is looking for effects on the vessels themselves rather than on blood.
So CPAP is about more than improving sleep. It’s also reducing red blood cell count.
I also eat low carb and have for a decade or more. My cholesterol is now around 100 and other lipid profile measure are equally good. My A1C dropped from 6.2 to 5.2 and has stayed there. After a decade of success, my doctor still admonishes me for not eating a low cholesterol diet. She can’t explain medically why, only that it is the policy of the Hospital. She quietly admits what I’m doing works and recommends low carb eating, but won’t do it officially.
