Sleep apnea affects an estimated 1 billion people worldwide — and most of them don’t know they have it. It’s one of the most underdiagnosed conditions in medicine, and one of the most damaging to your health.
Here’s how to know if you have sleep apnea, and what to do about it.
What Is Sleep Apnea?
Sleep apnea is a condition where your breathing repeatedly stops and starts during sleep. Each pause (called an apnea) can last anywhere from a few seconds to over a minute — and can happen hundreds of times per night.
There are three types:
- Obstructive Sleep Apnea (OSA): The most common type. The throat muscles relax and block the airway.
- Central Sleep Apnea: The brain fails to send proper signals to the breathing muscles.
- Complex Sleep Apnea: A combination of both types.
Why Sleep Apnea Is Dangerous
Each time your breathing stops, your brain partially wakes you up to restart it. You don’t remember these awakenings — but they fragment your sleep and deprive your body of oxygen hundreds of times per night.
Long-term untreated sleep apnea is linked to:
- High blood pressure
- Heart disease and stroke
- Type 2 diabetes
- Depression and anxiety
- Memory problems and cognitive decline
- Increased risk of accidents
The 10 Most Common Sleep Apnea Symptoms
1. Loud, Chronic Snoring
The most well-known symptom. Not everyone who snores has sleep apnea, but most people with sleep apnea snore — often loudly enough to wake their partner.
2. Witnessed Breathing Pauses
Your partner notices you stop breathing during sleep. This is one of the clearest warning signs of sleep apnea.
3. Waking Up Gasping or Choking
You suddenly wake up with a sensation of gasping, choking, or being unable to breathe. This happens when your brain forces you awake to restart breathing.
4. Excessive Daytime Sleepiness
Feeling exhausted and unable to stay awake during the day — even after what seems like a full night’s sleep. This is caused by the constant sleep fragmentation.
5. Morning Headaches
Waking up with a headache almost every morning. This is caused by low oxygen levels and elevated carbon dioxide during sleep.
6. Dry Mouth or Sore Throat Upon Waking
You wake up with a dry mouth or sore throat — a sign you’ve been sleeping with your mouth open, often due to airway obstruction.
7. Difficulty Concentrating
Brain fog, poor memory, and difficulty focusing during the day. Your brain isn’t getting the restorative sleep it needs.
8. Mood Changes
Irritability, depression, or anxiety that seems out of proportion. Sleep deprivation caused by apnea disrupts emotional regulation.
9. Frequent Nighttime Urination (Nocturia)
Waking up multiple times to urinate. Sleep apnea increases pressure in the chest, which triggers hormones that increase urine production.
10. High Blood Pressure That’s Hard to Control
Untreated sleep apnea is one of the most common causes of resistant hypertension — blood pressure that doesn’t respond well to medication.
Risk Factors for Sleep Apnea
You’re more likely to have sleep apnea if you:
- Are overweight or obese
- Have a large neck circumference (over 17 inches for men, 16 inches for women)
- Are male (men are twice as likely to have OSA)
- Are over 40
- Have a family history of sleep apnea
- Smoke or drink alcohol regularly
- Have nasal congestion or a deviated septum
How Is Sleep Apnea Diagnosed?
The gold standard is a polysomnography — an overnight sleep study done in a sleep clinic. However, home sleep tests are now widely available and accepted for diagnosing OSA.
If you suspect sleep apnea, talk to your doctor. They can order a sleep test and refer you to a sleep specialist.
Treatment Options
CPAP Therapy
The most effective treatment for moderate to severe OSA. A machine delivers continuous air pressure through a mask, keeping your airway open all night.
Oral Appliances
A mouthguard-like device that repositions the jaw to keep the airway open. Good for mild to moderate OSA.
Lifestyle Changes
- Losing weight (even 10% weight loss can significantly reduce apnea severity)
- Sleeping on your side instead of your back
- Avoiding alcohol and sedatives before bed
- Treating nasal congestion
Surgery
In some cases, surgical procedures to remove tissue or reposition the jaw can help.
What to Do If You Suspect Sleep Apnea
- Talk to your doctor and describe your symptoms
- Ask for a sleep study referral
- In the meantime, sleep on your side and avoid alcohol
- If your partner reports breathing pauses, take it seriously — this is urgent
The Bottom Line
Sleep apnea is serious, common, and very treatable. The biggest problem is that most people don’t know they have it.
If you recognize yourself in several of these symptoms, see a doctor. A proper diagnosis and treatment can literally change — and possibly save — your life.
