There's a wide variety of different types of physicians out there who will treat Sleep Apnea. I go to a "Sleep Specialist," but I'm not sure how common that is. I hear some people go to pulmonologists, others to ENTs, some to dentists, some to primary care physicians, etc.
First off, sleep medicine is a SUB-specialty. It is NOT a specialty in and of itself - yet. MOST accredited "sleep specialists" are Pulmonologists, Neurologists, and ENTs, but individuals from other specialties are also eligible for accrediation w/training. Fortunately, there are Pediatricians who have been accredited in sleep medicine.
My first sleep specialist was a neurologist specializing in sleep medicine. Since she elected to diddle around w/medications, etc., I managed to talk my way into a consultation at a local hospital sleep lab where I saw a pulmonologist/critical care doctor w/a sub-specialty in sleep medicine. There were two other sleep pulmos and a sleep neuro w/the hospital's sleep lab.When I was ready for another sleep study that sleep pulmo had moved to a new sleep lab in our area and I followed him there. This new sleep lab had two other sleep pulmos. When I went to Mayo Clinic's sleep lab I saw a sleep pulmo there, most likely because I also have COPD, not my choice and I wasn't at all impressed or pleased w/him. If I were to go back there at any time for sleep I would INSIST on another doctor and REFUSE to consult w/this one. If he were still there. He was NOT the calibre of doctor worthy of Mayo. The sleep techs were great! And it was a comfortable, attractive sleep lab.
