Sleep Apnea in Older Adults: Symptoms, CPAP, and When to See a Doctor

Sleep Apnea in Older Adults: Symptoms, CPAP, and When to See a Doctor

This page does not sell or recommend brands of CPAP machines or masks. Treatment choices belong to you and your clinician. In an emergency (severe chest pain, stroke signs, or trouble breathing while awake), call 911.

Key takeaways

• Sleep apnea means breathing stops and restarts many times during sleep, which can cut oxygen and fragment sleep.[1]
• Risk increases with age. Loud snoring, gasping, witnessed pauses, daytime sleepiness, morning headaches, and frequent nighttime urination are common clues — a bed partner often notices first.[2][3]
• Untreated sleep apnea may raise risk for hard-to-control high blood pressure, stroke, heart attack, AFib, type 2 diabetes, and dementia in older adults, among other problems.[4]
• A sleep study is often used to diagnose it. CPAP (or other PAP) is the most common treatment; lifestyle changes, oral devices, and (in selected cases) surgery are options.[1][5]
• Use PAP every time you sleep, including naps, if prescribed. Adjustments for mask fit and side effects are common — ask your clinician rather than quitting on your own.[4][6]

What sleep apnea is

NHLBI describes two main types:[1]

• Obstructive sleep apnea (OSA): the upper airway becomes blocked repeatedly (most common).
• Central sleep apnea: the brain does not send the right signals to breathe.

About 50 to 70 million Americans have a sleep disorder (broader than apnea alone).[1]

Symptoms that warrant a conversation

While asleep (often reported by someone else):[2]

• Breathing that starts and stops
• Frequent loud snoring (more common in men)
• Gasping for air

While awake:[2]

• Daytime sleepiness and tiredness (can affect learning, focus, and reaction time)
• Dry mouth
• Fatigue, headache, or insomnia (NHLBI notes these as more common in women)
• Waking often at night to urinate
• Decreased libido

Talk with your healthcare provider. You may need a sleep study.[2]

Why it matters more with age

Age raises risk as fatty tissue can build up in the neck and tongue.[3] Other risk factors include obesity, large tonsils/neck/tongue, hormone-related conditions, heart or kidney failure, alcohol, smoking, family history, and (for central apnea) conditions that affect brain control of breathing, including heart failure and stroke.[3]

Untreated apnea can contribute to:[4]

• Heart and vessel problems (including AFib, difficult-to-control high blood pressure, heart attack, heart failure, stroke)
• Type 2 diabetes
• Dementia in older adults
• Daytime sleepiness that impairs driving — NHLBI advises not driving if you feel tired or sleepy[4]

Diagnosis and when to seek care

Ask for evaluation if you snore loudly, gasp, have witnessed pauses, or feel excessively sleepy by day.[1][2] Diagnosis often involves a sleep study ordered by your clinician.[1]

Also tell surgeons and clinicians you have sleep apnea before procedures or when taking sedating pain medicines — NHLBI notes extra airway precautions may be needed.[4]

Treatment overview (education only)

Lifestyle (often first-line support)

NHLBI recommends regular physical activity, healthy sleep habits, healthy weight, limiting alcohol and caffeine, quitting smoking, and often side sleeping rather than back sleeping.[5]

Positive airway pressure (PAP / CPAP)

A PAP machine uses mild air pressure through a mask to keep airways open.[5][6]

Benefits may include better sleep quality, less snoring, less daytime sleepiness, help preventing or controlling high blood pressure, lower stroke risk, and better memory/cognitive function.[6]

Side effects can include congestion, runny nose, dry mouth or eyes, nosebleeds, or mask irritation. Stop and call your clinician right away if you have stomach discomfort or bloating.[5][6]

Insurance often works with a device supplier after a prescription; clinicians and insurers may check usage data.[4][6]

Other options

Oral (dental) devices, orofacial therapy, FDA-noted weight-loss medicine in selected people with obesity and moderate–severe apnea, and various surgeries (including hypoglossal nerve stimulation) may be considered when PAP is not tolerated or not enough.[5]

Getting used to CPAP (practical tips from NHLBI)

• Use it for all sleep, including naps and travel.[4][6]
• Practice wearing the mask while awake (for example watching TV).[4]
• Ask about humidifier settings, ramp features, or a different mask if you feel claustrophobic or leak air.[4]
• Clean the mask and tube as instructed; replace supplies on schedule.[4][6]

FAQ

Do I need CPAP forever? Many people need long-term treatment. Your clinician may repeat a sleep study after major weight change. Decisions are individualized.[4][5]

Is snoring always sleep apnea? No. Snoring is a clue, especially with pauses or daytime sleepiness, but only testing can diagnose apnea.[1][2]

Can I drive with untreated sleep apnea? Daytime sleepiness from untreated apnea can impair attention and raise crash risk. Do not drive when sleepy.[4]

Will Medicare or insurance cover CPAP? NHLBI states that after a prescription, insurance typically works with a medical device company. Coverage rules and usage requirements vary — ask your plan and supplier; this site does not process equipment sales.[6]
