Obstructive Sleep Apnea (OSA)
Heavy snoring and daytime sleepiness aren't normal — they're treatable.
Obstructive Sleep Apnea (OSA) is a condition in which the upper airway repeatedly collapses during sleep, dropping oxygen levels and fragmenting sleep. It doubles the risk of high blood pressure, atrial fibrillation, stroke and road traffic accidents.
Confirmed OSA is one of the most rewarding diagnoses in pulmonology — most patients on CPAP feel noticeably better within a week.
Symptoms we look out for
- Loud habitual snoring with witnessed pauses or gasps
- Daytime sleepiness — falling asleep at red lights, in meetings or while reading
- Morning headaches or dry mouth
- Resistant high blood pressure on 2+ medications
- Nocturia (waking multiple times to pass urine)
Diagnostics we offer
Our treatment approach
- CPAP therapy with personalised titration — the gold-standard treatment
- Weight management — even 5–10% loss can meaningfully reduce AHI
- Positional therapy and oral appliances in selected mild cases
- ENT referral for surgical options when CPAP cannot be tolerated
Common questions
Is CPAP for life?
CPAP is for as long as OSA is present. Significant weight loss or bariatric surgery can reduce or eliminate the need; a repeat sleep study confirms this.
Can a home sleep test replace a full polysomnography?
For most patients with high pre-test probability and no major heart or lung disease, yes. We choose the right test for your situation.
