Sleep apnea is a sleep-related breathing disorder in which breathing repeatedly stops and starts during sleep. Because these interruptions can happen while a person is unconscious, many people do not realize anything is wrong until a partner, family member, or doctor notices the signs.
The most common type is obstructive sleep apnea (OSA), which occurs when the upper airway becomes narrowed or blocked during sleep. Another type, central sleep apnea, occurs when the brain does not send the signals needed to control breathing properly.
Recognizing the symptoms can be an important first step toward getting an appropriate medical evaluation.
1. Loud or Persistent Snoring
Loud, frequent snoring is one of the symptoms commonly associated with obstructive sleep apnea. However, snoring by itself does not mean someone has sleep apnea. Many people snore without having the condition.
More concerning patterns include loud snoring followed by periods of silence, snorting, choking, or gasping. These changes may occur when airflow becomes restricted during sleep.
If a partner regularly notices unusual breathing patterns along with loud snoring, it is worth discussing the symptoms with a healthcare professional.
2. Pauses in Breathing During Sleep
One of the more recognizable signs of sleep apnea is when breathing appears to stop temporarily during sleep.
The person experiencing it may not know that it is happening. A bed partner may notice that the person becomes very quiet for several seconds and then suddenly starts breathing again, sometimes with a gasp or snort.
These repeated interruptions can occur throughout the night and may prevent normal restorative sleep.
3. Gasping, Choking or Snorting at Night
Some people with sleep apnea wake briefly because they are struggling to breathe. They may wake up gasping, choking, or taking a deep breath before quickly falling asleep again.
These awakenings can be so brief that the person does not remember them the next morning. As a result, someone may believe they slept continuously even though their sleep was repeatedly disrupted.
4. Excessive Daytime Sleepiness
Feeling unusually sleepy during the day is another important symptom.
A person may feel tired even after spending enough time in bed. They might struggle to remain alert while reading, watching television, working, studying, or sitting quietly.
Severe daytime sleepiness can also affect concentration, reaction time and daily activities. If someone regularly feels as though they could fall asleep during the day, it should not simply be assumed to be a lack of motivation or an ordinary busy schedule.
5. Waking With a Dry Mouth or Sore Throat
Some people with sleep apnea wake up with a dry mouth or sore throat.
This can occur particularly when breathing through the mouth during sleep. A dry mouth in the morning is not specific to sleep apnea, but when it occurs alongside loud snoring, nighttime breathing interruptions or daytime sleepiness, it may be worth discussing with a healthcare professional.
6. Morning Headaches
Morning headaches are another symptom reported with sleep apnea.
A headache after waking does not automatically mean that someone has sleep apnea because headaches have many possible causes. However, recurring morning headaches combined with other symptoms—such as snoring, gasping during sleep or excessive daytime sleepiness—can be a reason to seek further evaluation.
7. Difficulty Concentrating
Poor-quality sleep can affect how a person feels and functions during the day.
People with sleep apnea may experience difficulty concentrating, problems staying focused, or changes in alertness. Some may notice that tasks requiring sustained attention become harder than usual.
These symptoms can have many possible causes, so they should be considered alongside other sleep-related symptoms rather than used to diagnose sleep apnea on their own.
8. Irritability or Mood Changes
Sleep disruption can also affect mood. Some people with sleep apnea experience irritability, mood changes or feeling unusually frustrated during the day.
When sleep is repeatedly interrupted, the person may not feel refreshed after waking. Over time, persistent poor sleep can affect everyday wellbeing and concentration.
9. Frequently Waking During the Night
Repeated nighttime awakenings can occur with sleep apnea. A person may wake several times without understanding why.
Some people may also wake up feeling short of breath or notice difficulty returning to sleep. Frequent nighttime urination can also occur in people with sleep apnea.
10. Decreased Interest in Sex
Changes in sexual interest can occur among people experiencing sleep apnea. Reduced libido is listed among the possible symptoms associated with the condition.
However, reduced sexual interest can have many causes, including stress, medications, hormonal changes and other health conditions. It should therefore not be considered a standalone sign of sleep apnea.
Can You Have Sleep Apnea Without Snoring?
Yes. Not everyone with sleep apnea snores.
Snoring is common with obstructive sleep apnea, but its absence does not rule out the condition. Other symptoms, particularly witnessed breathing pauses, gasping during sleep and excessive daytime sleepiness, can also be important.
This is one reason why relying on snoring alone is not a reliable way to determine whether someone has sleep apnea.
When Should You Talk to a Doctor?
Consider speaking with a healthcare professional if you regularly experience symptoms such as:
- Loud or disruptive snoring
- Pauses in breathing during sleep
- Gasping or choking at night
- Excessive daytime sleepiness
- Repeated nighttime awakenings
- Morning headaches
- Dry mouth or sore throat after waking
- Difficulty concentrating or persistent irritability
A healthcare professional can review your symptoms, medical history and sleep habits and determine whether further testing is appropriate.
How Is Sleep Apnea Diagnosed?
Symptoms alone cannot confirm sleep apnea. Depending on the situation, a healthcare professional may recommend a sleep study, also called polysomnography, or an appropriate home sleep apnea test.
These tests can monitor breathing and other body functions during sleep. The American Academy of Sleep Medicine recommends objective sleep testing when obstructive sleep apnea is suspected rather than relying only on questionnaires or symptoms to make a diagnosis.
Final Thoughts
Sleep apnea can be difficult to recognize because many of its most important symptoms occur while a person is asleep. Loud snoring, breathing pauses, nighttime gasping and excessive daytime sleepiness are among the signs that deserve attention.
At the same time, individual symptoms can have other explanations. Having one or more of these signs does not automatically mean that you have sleep apnea. A proper medical evaluation and, when appropriate, sleep testing can help determine the cause of ongoing sleep problems.
If you regularly feel excessively sleepy during the day, wake up gasping, or someone notices that your breathing repeatedly stops while you sleep, consider discussing these symptoms with a qualified healthcare professional.
