Obstructive sleep apnea (OSA) means the upper airway repeatedly collapses during sleep, cutting oxygen and fragmenting rest. It affects millions of adults—and many cases remain undiagnosed because partners notice snoring before patients connect the dots.
Symptoms and partner observations
- Loud snoring, choking or gasping during sleep
- Daytime sleepiness, morning headaches, poor focus
- High blood pressure resistant to treatment
- Waking with dry mouth; restless sleep
Why it matters for long-term health
Untreated OSA is linked to hypertension, atrial fibrillation, stroke risk, type 2 diabetes, and motor vehicle accidents from sleepiness. Treatment can improve quality of life and cardiovascular markers.
Diagnosis
Sleep studies (in-lab polysomnography or validated home devices) measure breathing, oxygen, and sleep stages. Screening questionnaires help prioritise who needs testing.
Treatment options
- CPAP—positive airway pressure; gold standard for moderate–severe OSA
- Weight loss where appropriate, side-sleeping, avoiding alcohol before bed
- Oral appliances from dental sleep specialists for mild–moderate cases
- Surgery or hypoglossal nerve stimulation in selected patients
Questions to ask your doctor
- Should I have a sleep study based on my symptoms?
- Is a home test accurate enough for me?
- What CPAP mask types are easiest to tolerate?
- Could sleep apnea explain my resistant blood pressure?
- When is it unsafe to drive until treated?
