Many symptoms of sleep apnea happen at night, so you may not even notice them. However, you may notice that you have symptoms that occur during the day, such as excessive drowsiness and confusion. If for any reason you suspect you have sleep apnea, you should talk to a professional like Dr. Aluning who can refer you to a specialist. Dr. Aluning can also help detect signs of sleep apnea such as abnormally large tissues in the throat or blockage in the airways during a dental exam.
