I have obstructive sleep apnea and now I have flu is this dangerous and should I see my doctor.

FLU-SLEEP APNEA NG. Sleep apnea itself is a disease that can have deadly consequences. So can the flu. Don't self diagnose. Have an MD see you immediately to conclude you have the flu and get it treated. If you have been diagnosed with sleep apnea and are not being treated, stop procrastinating.
Seasonal flu + OSA. is very common viral infection. Usually the condition resolves on its own with home care. Drink water and get a good rest. NSAIDs (e.g. Aleve, Advil) or Tylenol (acetaminophen) are also recommended every 6 hours. An untreated obstructive sleep apnea (OSA) can have a significant impact on your personal health. If concerned, see your PCP for examination.
