It can be an indicator, but you don’t have to snore to have it. I think if you fit any of these:

- male

- overweight

- tired in the daytime

you should go for a sleep study! I got diagnosed with obstructive sleep apnea. It almost ruined my life, causing me to drop out of my engineering course. I would fall asleep in lectures and do no work, with no energy to push myself. I was diagnosed a couple of years ago, had sinus surgery to remove obstructions, am losing weight and I’m using a cpap machine. I’m feeling better and now I’m 1 year away from getting my degree. Go and get the study done!!!
