A local sleep specialist is a healthcare professional who specializes in diagnosing and treating sleep disorders. Research shows that sleep apnea is about 70% more prevalent in people with type 2 diabetes. Often, this is due to obesity. Other sleep disorders a local sleep specialist may treat include insomnia, restless leg syndrome, snoring and sleepwalking. Depending on your condition, a local sleep specialist may want to perform a sleep test, which involves attaching electrodes to your body to monitor heart rate, brain waves and eye movement while you sleep. Or, they may prescribe medication or refer you to a psychologist or psychiatrist if they feel that would be beneficial.
