My mother has had vertigo for about a month now, and I’m sure I know what is causing it. She has been a loud snorer for a long time, and recently discovered that if she tapes her mouth shut while sleeping, it stops her from snoring, and she even gets better rest. After a bit of research, I am convinced that this is the cause of her vertigo, as it could limit the level of oxygen in her bloodstream, and there are no other obvious answers to what could be causing it. I need a medical professional, to back up my theory that this could cause vertigo, so she will take me seriously. I’m very concerned for her, so please help me talk her into no longer taping her mouth shut while sleeping, thank you
