When Should You See a Sleep Specialist?

What does sleep medicine cover?

Sleep medicine deals with problems involving sleep quality, sleep timing, breathing during sleep, nighttime movements and daytime alertness. Similar symptoms can arise from different causes, so assessment starts with a careful history rather than a standard test package. [1]

A primary care doctor can assess many common sleep concerns. Specialist input is particularly useful when symptoms persist, the diagnosis is unclear, breathing pauses are reported, or treatment has not helped.

Six reasons to arrange an assessment

1. Loud snoring with gasping or breathing pauses

A partner may notice pauses followed by a snort or gasp. These symptoms can suggest obstructive sleep apnea, in which the upper airway repeatedly narrows or closes during sleep. Snoring alone does not confirm the diagnosis, and body size alone does not rule it out. Read our obstructive sleep apnea guide . [2]

2. Sleepiness that interferes with daily life

Unintentionally dozing during conversations, work or other activities is different from simply feeling low in energy. Possible explanations include insufficient sleep, disrupted breathing, medicines, shift work or a less common sleep disorder. Tell your clinician about both your time in bed and the amount of sleep you actually obtain. [1,2]

3. Ongoing difficulty falling asleep or staying asleep

Difficulty sleeping despite having the opportunity to sleep may reflect insomnia. Pain, mood, medication, breathing problems and sleep timing can contribute. A sleep diary and clinical assessment are often more useful initially than an overnight study. [3]

4. Restless legs or movements that disrupt sleep

An uncomfortable urge to move your legs while resting, particularly in the evening, is worth discussing. Repeated kicking noticed by a partner can have different explanations. Your clinician will decide whether a history, blood tests or further investigation is appropriate. [1]

5. Sleep timing that does not fit daily life

Shift work or a body clock that runs much later than your required schedule can make it difficult to sleep at the intended time. Recording work hours, naps, caffeine and sleep times can help clarify the pattern. [1,3]

6. Unusual or potentially dangerous behavior at night

Sleepwalking, acting out dreams or episodes that cause injury need assessment. Some patients require an attended study, neurological evaluation or another specialist referral. A routine home breathing test may not answer this type of question. [1,4]

What happens at the first consultation?

Your doctor asks about bedtime and waking times, symptoms, daytime alertness, medical conditions and medicines. Observations from someone who shares your room can be valuable. Questionnaires may help organize the assessment, but they cannot diagnose sleep apnea on their own. [2,3]

• Bring a medication list and any previous sleep-study reports.
• If you use CPAP, bring your available device reports and describe mask or comfort problems.
• Keep a sleep diary for one to two weeks if practical: record sleep times, awakenings, naps and daytime sleepiness.
• Note whether the problem changes on weekends, holidays or different work shifts.

Will you need a sleep study?

That depends on the question being investigated. Polysomnography records sleep and several body signals overnight. Home tests differ in what they measure; a Level 2 home polysomnogram includes sleep-stage recording, whereas a simpler respiratory study may not. The clinician chooses an appropriate test and setting. [4]

Australian Polyclinic offers Level 2 home sleep studies for suitable patients. Visit the sleep laboratory page for practical information. Some medical conditions or unusual sleep events need a different investigation or an attended laboratory assessment.

Overnight oxygen monitoring provides more limited information. It does not measure sleep stages and cannot reliably exclude sleep apnea by itself. Read our overnight oximetry guide to understand its role.

If symptoms remain concerning after a negative or technically inadequate study, discuss the next step with your physician rather than assuming that every sleep disorder has been excluded.

What treatment might involve

Treatment follows the diagnosis. It may involve changes to sleep opportunity or timing, review of contributing conditions and medicines, or specific therapy for a sleep disorder.

For chronic insomnia, cognitive behavioral therapy for insomnia (CBT-I) is a recommended treatment. It is a structured therapy, not simply a list of sleep-hygiene tips. Access to an appropriate provider or referral can be discussed during assessment. [5]

For obstructive sleep apnea, options depend on the clinical findings and may include positive airway pressure and other approaches. If CPAP is prescribed, fitting the mask and arranging follow-up matter. Our first-month CPAP guide explains common early adjustment issues.

Common questions

Should I book a consultation or a sleep study first?

If you are unsure which test you need, start with a consultation. If you already have a referral, share it with the team so the requested study and suitability can be confirmed.

Can I have insomnia and sleep apnea together?

Yes. Difficulty sleeping does not exclude a breathing disorder. Mention snoring, gasping and witnessed pauses even if your main concern is insomnia.

Does every sleep problem require CPAP?

No. CPAP is used for particular breathing-related conditions; it is not a general treatment for every cause of poor sleep.

Patient information only; an individual assessment is needed for diagnosis and treatment. Do not change prescribed medication solely on the basis of this guide.
