Obstructive sleep apnoea (OSA) is a condition in which the muscles in the throat relax too much during sleep, causing the airway to narrow or close repeatedly. This interrupts breathing, often dozens of times a night, and disturbs sleep quality even if you don't fully wake up.

What is Obstructive sleep apnoea?
Obstructive sleep apnoea (OSA) is a condition in which the muscles in the throat relax too much during sleep, causing the airway to narrow or close repeatedly. This interrupts breathing, often dozens of times a night, and disturbs sleep quality even if you don't fully wake up.
Common symptoms include loud snoring, gasping or choking during sleep, excessive daytime tiredness, and morning headaches. Risk factors include excess weight, a narrow airway, smoking, alcohol use, and sleeping on your back.
02 · Understand
Clinical context
Self-care advice
A sleep study, which can often be done at home, is used to diagnose sleep apnoea and assess its severity.
03 · Act
When to see a doctor
- 1You or your partner notice loud snoring with pauses in breathing during sleep
- 2You feel excessively sleepy during the day despite a full night's sleep
- 3You wake up gasping, choking, or with a dry mouth and headache
- 4Daytime sleepiness is affecting your ability to drive or work safely
- 5You have high blood pressure that isn't responding well to treatment, which can sometimes be linked to undiagnosed OSA

Practical steps
Take these self-care steps
These measures can help ease symptoms, support recovery, and reduce the chance of things worsening — but they don't replace medical advice if symptoms are severe or persistent.
- 1Maintain a healthy weight.Excess weight around the neck can narrow the airway, so weight loss where relevant can significantly reduce symptoms.
- 2Avoid alcohol and sedatives before bed.These relax throat muscles further and can worsen apnoea episodes.
- 3Try sleeping on your side.Sleeping on your back allows the tongue and soft tissues to fall backward more easily, worsening airway blockage.
- 4Use prescribed treatment consistently.If a CPAP machine or dental device is recommended, using it every night gives the most benefit.
- 5Address nasal congestion.Treating a blocked nose can make breathing during sleep easier and improve treatment effectiveness.

BarnMD Bottom Line
Sleep apnoea is very treatable once diagnosed, and addressing it can dramatically improve energy, mood, and long-term heart health.
Untreated sleep apnoea increases the risk of high blood pressure and heart problems, so getting assessed is worthwhile if you have symptoms.
