If you have concerns about your health and breathing, then you should always seek the help of a medical professional, or your doctor. Your doctor can then help to diagnose your condition based on symptoms, tests or examination. If you feel that you may have obstructive sleep apnea, then you will be referred to a specialist, or for a sleep study for further tests.
Once you have these tests, you may also have your throat, mouth, and nose inspected in case there are any abnormalities or extra tissue. Once all examinations have taken place, then you will be given a diagnosis, and offered the best type of treatment for your condition. Depending on the severity of the obstructive sleep apnea, you may be offered a CPAP machine.
