Sleep apnea contributes to AFib.
And if you are overweight, odds are you do have sleep apnea.
Look into getting a cpap machine.
My wife has used a CPAP for a long time. She probably would die without it.
Undiagnosed sleep apnea is a silent killer.
If you wake up more than twice a month with dull headache, pounding heart, feeling like you hardly slept when it’s been six or more hours... ANY of these by itself may indicate you should see a pulmonologist, and maybe campaign for an in-clinic sleep study.
I had a coworker in his thirties diagnosed with heart disease that later traced to apnea he’d never known about. He got a hanle on that, but damage had already been done.
I woke one morning with AFib out of the clear blue sky and five hours later the cardiologist was just going to put me on statins and add me to his roster. A friend in respiratory medicine said, “Hold off on the drugs; go see a pulmonologist, first; you might be an apnea case.” I did. I am. Second worst in the doctor’s practice, and my physiology gave zero hints.
