Sleep Apnea: Warning Signs, Sleep Quality, and When to Get Help
Snoring is often treated as a joke, but loud snoring with pauses in breathing can be a sign of obstructive sleep apnea, a common and treatable condition. It is worth knowing the warning signs because many people live with it for years without realising.
Key takeaways
- Obstructive sleep apnea means the airway repeatedly narrows or closes during sleep.
- Loud snoring, gasping and heavy daytime sleepiness are warning signs.
- Only a sleep study can diagnose it, and effective treatment is available.
What happens
In obstructive sleep apnea, the muscles at the back of the throat relax too much, and the airway partly or fully blocks. Breathing pauses, oxygen can dip and the brain briefly wakes you to restart breathing, often without you remembering. The result is broken sleep and a tired day.
Warning signs
- Loud, persistent snoring.
- Gasping, choking or pauses noticed by a partner.
- Waking with a dry mouth or morning headache.
- Heavy sleepiness, falling asleep while driving or at a desk.
- Difficulty concentrating and irritability.
Who is at risk
Risk rises with excess weight, a larger neck, older age, nasal obstruction, alcohol and certain medicines. It affects men more often, but it is common in women too, especially after menopause. Children can have it as well, often linked to enlarged tonsils.
Why it matters
Untreated sleep apnea is associated with high blood pressure, heart rhythm problems, type 2 diabetes and accidents caused by drowsiness. Treating it often improves energy, mood and blood pressure.
Diagnosis and treatment
A doctor may arrange a home sleep test or an overnight laboratory study. Treatments include continuous positive airway pressure (CPAP), oral appliances, weight loss, positional therapy, treating nasal problems and sometimes surgery. Avoiding alcohol close to bedtime helps. See alcohol and sleep.
Do not self-diagnose
Trackers and apps can raise a flag but cannot diagnose apnea. If you recognise these signs, speak to a doctor. If you are very sleepy while driving, treat it as urgent and avoid driving until it is assessed.
Frequently asked questions
Is snoring always sleep apnea?
No. Many people snore without apnea. Snoring combined with pauses in breathing and daytime sleepiness is more concerning.
Can sleep apnea be cured?
It can often be well controlled, and weight loss helps some people. Many need ongoing treatment such as CPAP.
