Sleep apnea is very common, affecting roughly 1 in 10 people, but varies by definition, with some studies showing 5-15% of the general population having it, while broader definitions (even mild cases) suggest it could be as high as 20-30% or more, especially in men, older adults, and those with obesity, with most cases (up to 90%) undiagnosed.
The National Sleep Foundation reported that sleep apnea likely affects as much as 20% of the population, and it's been found that around 85% of individuals with sleep apnea don't know they have it. Part of this may be because the symptoms of sleep apnea are somewhat general.
Highlights. Sleep hypopnea is defined as a drop of ≥30% in breathing amplitude and in oxygen saturation >3% (AASMedicine), or >4% (CMMS). This study reveals a systematic bias, with the 3% criterion consistently yielding higher apnea/hypopnea index values.
Pregnancy can trigger sleep apnea due to hormonal fluctuations, weight gain, and increased fluid retention. These changes can cause your airway to become more restricted, especially in the second and third trimesters. New snoring or nighttime breathing issues should be evaluated as early as possible.
This is commonly caused by obesity, large tonsils, nasal congestion, or drinking alcohol before falling asleep. Central sleep apnea is less common and occurs when the brain does not send the correct signals required to breathe. Common causes include heart failure, neuromuscular disorders, and chronic opioid use.
Sleep apnea can occur at any age, but is most common between ages 2 and 8 during the period of peak tonsil growth. Children with sleep apnea typically aren't overweight and are developmentally appropriate, explains Dr. Reddy. However, obesity is a risk factor for sleep apnea in children.
Also, while you have a higher risk of sleep apnea with obesity, anyone of any body size can develop this condition.
Sleep apnea warning signs include loud snoring, gasping or choking during sleep, pauses in breathing (noticed by a partner), excessive daytime sleepiness, morning headaches, irritability, and frequent nighttime urination, all stemming from disrupted, poor-quality sleep. These symptoms indicate breathing stops and starts, leading to fatigue and concentration issues during the day, so seeing a doctor is crucial for diagnosis and treatment.
Sleep apnea can be linked to miscarriages. It affects sleep and lowers oxygen levels, which can upset hormones and blood flow important for a healthy pregnancy. Early treatment of sleep apnea helps improve oxygen levels, balance hormones, and reduce risks of pregnancy complications.
Sleep apnea, cardiovascular risk and metabolism
Several studies have shown an association between sleep apnea and problems like type 2 diabetes , strokes , heart attacks and even a shortened lifespan, says Jun.
The amount of time that a sleep apnea patient stops breathing can be from 10 seconds to two minutes or more. These breathing "stoppages" can happen a few times per hour or, in more severe cases, 60-100 times per hour or to the point where someone spends more time NOT breathing than they are breathing.
Like many sufferers, Shaq was unaware that he had sleep apnea until his partner told him about his pattern of snoring and gasping for breath. After completing a sleep study and being diagnosed with moderate sleep apnea, Shaq was fitted with a CPAP mask to get a better night's rest.
Go to bed and get up at the same time every day, including weekends. Being consistent reinforces your body's sleep-wake cycle. If you don't fall asleep within about 20 minutes of going to bed, leave your bedroom and do something relaxing. Read or listen to soothing music.
In contrast, two-thirds of patients with mild and moderate disease, as assessed by the 3 nights of testing, would be accurately classified with 1 night of monitoring. The remaining one-third would be either underdiagnosed or overdiagnosed.
You wake up enough to take a few breaths, but not enough to remember it the next morning. This cycle repeats itself many times each night, making you feel tired or exhausted in the morning. When you have OSA, the apnea is caused by an obstruction or blockage.
“Sleep on your side with your back mostly straight. This the best sleep position as it reduces apnea severity and snoring,” Dr. Knobbe said. It can also help keep your spine in proper alignment, although it can put additional strain on your shoulders, hips and spine.
Yes—a thin person can absolutely have sleep apnea. While carrying excess weight increases risk, many people with normal or low body weight still experience this disorder.
Breathing / Medical Disorders That May Be Mistaken for Sleep...
The cardinal symptoms of sleep apnea include the "3 S 's": S noring, S leepiness, and S ignificant-other report of sleep apnea episodes.
Sleep apnea doesn't always announce itself with dramatic symptoms like gasping or choking. The quieter signs—morning headaches, mood changes, frequent urination, and fatigue—can be just as telling. If you've been struggling with any of these issues, don't wait to seek help.
Sleeping on your back often worsens apnea, while sleeping on your side may lesson episodes of apnea. When you are lying on your back, your tongue and soft palate tend to fall back to the throat, which can increase breathing difficulties.
A person with OSA has times during sleep in which air cannot flow normally into the lungs. The block in airflow (obstruction) is usually caused by the collapse of the soft tissues in the back of the throat (upper airway) and tongue during sleep.
Many people with sleep apnea experience loud and regular chronic snoring. Their airway partially collapses during sleep, making it difficult for air to flow smoothly. This results in vibrations in the throat, creating a deep, rumbling sound.
Studies show that individuals with obstructive sleep apnea often see remarkable improvements in sleep quality and overall health after losing weight. Even a modest weight loss of 10-15% can substantially reduce sleep apnea symptoms, including mild sleep apnea.
