Thanks for your question on Healthcare Magic.
I can understand your concern.
Sleep apnea is systemic disease. If don't treat it, it will damage all organs of the body.
So if your N3 sleep is not proper, you are at risk of
hypertension,
diabetes, stroke, coronary artery disease,
respiratory failure,
dyslipidemia, chronic headache, mood changes etc.
So better to start treatment for sleep apnea as soon as possible.
BiPAP machine with proper titration is the treatment of choice.
Weight reduction is also-ran very important.
So consult your sleep specialist and start treatment.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
