Loud Snoring and Daytime Sleepiness: Is It Sleep Apnea?
In brief
H1: Loud snoring and daytime sleepiness: when to think of sleep apnea In brief
- Snoring is common, but loud snoring with pauses in breathing or gasping can mean obstructive sleep apnea.
- Sleep apnea lowers oxygen many times a night and raises BP and heart risk.
- Daytime sleepiness, morning headaches and poor concentration are common signs.
- A sleep study confirms it.
- Treatment, including weight loss and CPAP, often improves sleep, energy and BP.
Snoring or sleep apnea?
Snoring is the sound of air moving past relaxed tissues in the throat. Many people snore, especially after a tiring day, with a cold or after alcohol. On its own, it is often harmless.
Sleep apnea is different. The throat narrows so much that breathing stops or becomes very shallow for 10 seconds or more, many times every hour. Each time, oxygen drops and the brain wakes you briefly to restart breathing. You usually do not remember these awakenings, but your body feels them.
Signs to look out for
At night (often noticed by a partner):
- loud snoring most nights
- pauses in breathing, then a gasp or snort
- choking or waking up breathless
- restless sleep, getting up often to pass urine
During the day:
- feeling sleepy while reading, watching TV or travelling
- dozing off at work or while driving
- morning headache or dry mouth
- poor memory and concentration
- irritability or low mood
Why it matters for your heart and sugar
Every drop in oxygen sets off a stress response that raises heart rate and blood pressure. Over months and years, this contributes to:
- high BP, especially BP that stays high despite medicines
- irregular heart rhythm such as atrial fibrillation
- heart failure and stroke
- harder-to-control diabetes
- weight gain, which then worsens sleep apnea
Sleep apnea is one of the most common hidden causes of high BP that does not come down with medicines.
Who is at higher risk
- Extra weight, especially around the neck and waist
- Collar size above 16 to 17 inches
- High BP, diabetes, heart rhythm problems
- Men, and women after menopause
- Older age
- Blocked nose, large tonsils, or a small lower jaw
- Alcohol or sleeping pills at night
How it is tested
A sleep study records your breathing, oxygen level, pulse and position through the night. The key result is the number of breathing pauses or shallow breaths per hour. Dr. Das, who holds a Diploma in Obstructive Sleep Apnea, explains what the result means and the options.
What treatment involves
- Weight loss, if needed, which often reduces apnea
- Sleeping on your side if apnea happens mainly on your back
- Avoiding alcohol and sleeping pills at night
- Treating a blocked nose
- CPAP, a small machine that blows gentle air through a mask to keep the throat open; the most effective treatment for moderate or severe sleep apnea
- Dental devices or surgery for selected people, through referral
FAQs
Can thin people have sleep apnea?
Yes. Weight is a major risk factor, but thin people can have sleep apnea because of a narrow airway, a small jaw, large tonsils or a blocked nose. If you have the signs, get checked whatever your weight.
Is CPAP for life?
CPAP works while you use it, so most people with moderate or severe sleep apnea use it long term. If you lose a lot of weight or have other treatment, a repeat sleep study can show whether CPAP is still needed.
Can snoring harm my partner?
It can disturb their sleep and cause tiredness. More importantly, your partner is often the first to notice breathing pauses. If they have noticed you stop breathing or gasp at night, please get checked.
Will treating sleep apnea lower my BP?
In many people, yes, especially when BP has been hard to control. Treatment also improves energy, concentration and mood. BP medicines may still be needed, but often work better.
