What does a sleep specialist do that your primary care doctor cannot? It is a fair question, and one worth answering before you spend another year telling yourself the exhaustion is just stress. A sleep specialist is a physician or advanced practice provider with dedicated training in the disorders that disrupt sleep and the physiology behind them. At uNITE Sleep Institute, that means evaluating why you are not sleeping well, ordering and interpreting the right diagnostic testing, and managing treatment until your nights improve. Below is a clear look at what the role involves, when it makes sense to see one, and how the process works at our locations across Nevada and Arizona.
What Does a Sleep Specialist Do, Exactly
The short version is that a sleep specialist diagnoses and treats disorders of sleep and breathing during sleep. The longer version is more interesting, because the work spans several disciplines at once.
A sleep specialist takes a detailed history covering your sleep schedule, bedtime habits, medications, caffeine and alcohol use, mood, weight, and what your bed partner has observed. They perform a physical exam that pays particular attention to the airway, nasal passages, neck circumference, and cardiovascular signs. They decide whether a sleep study is warranted and, if so, which type. They interpret the resulting data, which for an in-lab study can run to hundreds of pages of brain wave, breathing, oxygen, and limb movement recordings. Then they build and adjust a treatment plan and follow you over time to confirm it is working.
That last part is where people are often surprised. What does a sleep specialist do after the diagnosis is delivered? A great deal, as it turns out. Diagnosis is the beginning of the relationship at uNITE Sleep Institute, not the end of it.
The Training Behind the Title
Sleep medicine is a subspecialty, which means physicians arrive at it after completing residency in another field first, commonly pulmonology, neurology, psychiatry, internal medicine, or cardiology. They then complete additional fellowship training in sleep medicine and sit for board certification. Advanced practice providers who specialize in sleep bring their own certification and years of focused clinical experience.
The result is a team that sees the same symptom from different angles. Our clinical team at uNITE Sleep Institute reflects that on purpose. Dr. Alan D. Steljes is a cardiologist and sleep medicine specialist who integrates cardiovascular health into sleep diagnostics. Dr. Haramandeep Singh is board certified in sleep medicine with experience across a wide range of disorders. Dr. Gregory Tirdel is a pulmonologist focused on complex respiratory-related sleep issues. Sarah Teixeira, DNP, has more than fourteen years of clinical experience and specializes in sleep apnea management, pressure therapy compliance, and sleep hygiene. Sarah Patterson-Hunold, DNP, is double board certified in sleep medicine and weight management. Licensed respiratory therapists and registered polysomnographic technologists support every study.
Conditions a Sleep Specialist Evaluates
Sleep apnea is the condition most people associate with the field, and for good reason, but it is only part of the picture. A sleep specialist evaluates obstructive sleep apnea, central sleep apnea, insomnia, restless legs syndrome, circadian rhythm disorders tied to shift work or travel, excessive daytime sleepiness including narcolepsy, and parasomnias such as sleepwalking, night terrors, and REM sleep behavior disorder. Many patients arrive with more than one of these overlapping, and untangling which is driving the others is a large part of what does a sleep specialist do differently from general practice.
The stakes go well beyond feeling tired. Untreated sleep apnea is associated with high blood pressure, atrial fibrillation, stroke, type 2 diabetes, and depression. Chronic insomnia carries its own cardiovascular and mental health burden. Part of what a sleep specialist does is connect the symptom you noticed to the risk you did not.
How Testing Works
Ask what a sleep specialist does with the information from your visit, and testing is usually the next step. At uNITE Sleep Institute, you have two paths.
Home Sleep Testing
A small FDA-cleared device is provided to you and worn for one night in your own bed. It records breathing patterns, oxygen levels, and other vital data. It is convenient, comfortable, and appropriate for straightforward suspected obstructive sleep apnea. Most patients receive results and a personalized plan within forty-eight hours.
In-Lab Sleep Studies
Conducted overnight in a private, hotel-style suite at one of our accredited centers, with technologists monitoring in real time. An in-lab study captures far more, including sleep stages, limb movements, cardiac rhythm, and body position. It is the right choice for complex cases, suspected central apnea, parasomnias, seizures during sleep, or when a home test comes back inconclusive.
Every study is interpreted by a board-certified physician. No algorithm hands you a diagnosis at uNITE Sleep Institute, and no result goes out without a physician reviewing the raw data behind it.
Treatment and Ongoing Management
Once a diagnosis is confirmed, what does a sleep specialist do next depend entirely on what the testing showed. For obstructive sleep apnea, that may mean CPAP therapy with setup, mask fitting, and pressure adjustment, or an oral appliance for patients who cannot tolerate pressure therapy. For insomnia, treatment often centers on cognitive and behavioral approaches rather than medication, delivered through a structured insomnia management program. For restless legs syndrome, it may involve laboratory work to check iron stores and targeted medication. For circadian disorders, it may mean light timing, schedule restructuring, and coaching.
Follow-up is not optional. What does a sleep specialist do in those return visits? They review adherence data, troubleshoots mask leaks and pressure discomfort, adjusts therapy, and repeats testing when clinically indicated. At uNITE Sleep Institute, we also address weight management where it is a contributing factor, because treating the airway without addressing what is narrowing it is only half the work.
When to See a Sleep Specialist
Consider making an appointment if you snore loudly, gasp or choke during sleep, or have been told you stop breathing at night. The same applies if you wake unrefreshed despite adequate hours in bed, fall asleep during meetings or while driving, take more than thirty minutes to fall asleep on most nights, wake repeatedly and cannot return to sleep, experience restless or tingling legs in the evening, or act out dreams. Morning headaches, a dry mouth on waking, high blood pressure that resists treatment, and unexplained daytime fatigue are all worth mentioning.
You generally do not need a referral to begin. Most patients can self-refer, and our team verifies insurance benefits and handles authorizations before your first visit.
