Sleep apnea isn't caused by one single organ but by issues in the upper airway (throat), leading to collapse (obstructive) or the brain, failing to signal breathing muscles (central). Key culprits for obstructive apnea include the tongue, soft palate, tonsils, and throat tissues relaxing and blocking airflow, while central apnea stems from the brain's control system for breathing muscles failing, often linked to heart conditions or stroke.
Obstructive sleep apnea (OSA).
In this condition, the muscles in your throat relax while you're asleep, causing surrounding tissue to press on your windpipe. This blocks air movement.
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.
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.
If left unaddressed, the sleep disorder can trigger a host of health problems that can shorten your lifespan and diminish your quality of life. "Sleep apnea is closely linked to serious conditions like high blood pressure, heart disease, and even stroke. Untreated, it creates a lot of strain on the body.
Sinusitis. Because sinusitis causes inflammation throughout the human sinus cavity, this condition can mimic sleep apnea. Both conditions can cause snoring, gasping for air at night, breathing interruptions, and poor sleep quality.
Anyone at any age can have obstructive sleep apnea. But it's most common in middle-aged and older adults. Only about 1 in 50 children have obstructive sleep apnea. It's also more common in men than in women.
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.
Causes of sleep apnoea
obesity. having a large neck. getting older – although children and young adults can also get it. having other family members with sleep apnoea.
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.
Excess Weight
As a person gains weight, the tissue on their throat and chest places more and more pressure on their airway when they lay down to sleep, making stoppages in breathing stemming from sleep apnea more frequent.
Some common sleep apnea causes and risk factors include: Obesity – Obesity dramatically increases the risk of sleep apnea. Fat deposits around your upper airway can obstruct your breathing. Narrow Airways – You might have inherited a narrow throat.
Conclusions: White matter is extensively affected in OSA patients; the alterations include axons linking major structures within the limbic system, pons, frontal, temporal and parietal cortices, and projections to and from the cerebellum.
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.
Research has shown that even a small amount of weight loss can open up your throat and improve sleep apnea symptoms. In some cases, losing a significant amount of weight could even cure the condition. However, it's important to remember that everyone is different, and what works for one person may not work for another.
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.
You may have upper airway resistance syndrome (UARS). Upper airway resistance syndrome can be confused with sleep apnea, but they're not the same thing. Keep reading to discover why, if it's not sleep apnea, it could be upper airway resistance syndrome.
How Long to Expect for Noticeable Improvement? Within weeks, you will see improvement in sleep quality, reduced fatigue, and better focus. Within months, your cognitive recovery will be noticeable, and you will be at a reduced risk of heart problems.
However, there are still some common signs that should prompt you to get checked and seek treatment for sleep apnea:
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.
“Sleep on your side with your back mostly straight. This the best sleep position as it reduces apnea severity and snoring,” Dr. Knobbe said.
Sleep apnea rate significantly increases as we age. 10% of men age 30-49 are likely to have sleep apnea, while 3% of women in the same age range are likely to have sleep apnea. 17% of men and 9% of women age 50-70 are likely to have sleep apnea.
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.
In December 2024, FDA approved the first drug for sleep apnea: the injectable treatment tirzepatide (Zepbound), previously approved to treat obesity, which targets the glucagonlike peptide-1 receptor and another metabolism-related receptor.
