Sleep apnea is a condition that affects your breathing while you sleep, causing you to stop breathing entirely. This can be due to a blockage of your airway (obstructive sleep apnea) or because your brain doesn't control your breathing as expected (central sleep apnea). Sleep apnea can be treated with a CPAP machine, which pumps air into a mask worn over the nose or mouth to keep the airway open. Lifestyle changes, such as losing weight, reducing alcohol intake, and avoiding sleep-inducing medications before bed, can also help manage the condition. In some cases, surgery may be recommended to remove tissue blockages or create a new airway.

What You'll Learn
Obstructive sleep apnea (OSA)
The "gold standard" treatment for OSA is Continuous Positive Airway Pressure (CPAP) therapy, which uses a machine to pneumatically stabilize the upper airways and improve breathing during sleep. CPAP has proven efficacy and potential cost savings due to decreased health complications and motor-vehicle crashes associated with OSA. However, some patients may find CPAP intolerable due to side effects, and adherence can be as low as 50% in certain populations.
Other non-surgical treatments for OSA include positional therapy, oral appliances, nasal resistors, oropharyngeal exercises, and behavioral measures. Oral appliances, such as mandibular advancement devices, can stabilize the tongue, advance the mandible, or lift the soft palate to increase the volume of the upper airways and prevent collapse. Positional therapy involves adjusting your sleeping position to improve breathing. Nasal resistors are devices that fit inside the nostrils and work by creating resistance and increasing muscle activity in the upper airway, which helps to keep the airway open during sleep. Oropharyngeal exercises can also help to strengthen the muscles in the throat and improve airflow.
Behavioral measures, such as weight loss, frequent physical exercise, and avoiding alcohol and sedative medication before bedtime, can also help manage OSA. Losing weight can reduce the amount of tissue pressing on the windpipe, improving airflow. Regular physical exercise can improve overall health and breathing, while avoiding alcohol and sedatives before sleep can prevent muscle relaxation and airway obstruction.
In some cases, surgery may be considered as part of a comprehensive treatment approach for OSA. Surgical techniques can help to increase the size of the airway, reducing the likelihood of collapse during sleep and improving breathing.

Central sleep apnea (CSA)
CSA can manifest in different forms, including narcotic-induced CSA, where opioid medications disrupt breathing patterns, and high-altitude periodic breathing, which occurs at elevations above 2,500 meters (8,000 feet). Treatment-emergent CSA can develop as a result of positive airway pressure treatment for OSA, while medical condition-induced CSA can be caused by heart failure, Parkinson's disease, stroke, kidney failure, or other neurological disorders. Idiopathic CSA refers to cases where there is no clear cause.
CSA is estimated to affect approximately 0.9% of individuals over 40 years of age in the United States, with a higher prevalence in older adults, especially those over 65. Men are at a higher risk of developing CSA, and certain conditions, such as neurological diseases and brainstem injuries, may increase the likelihood of CSA.
The symptoms of CSA include excessive daytime sleepiness, restless or poor-quality sleep, abnormal breathing patterns, and nighttime chest discomfort. CSA can lead to fragmented sleep, resulting in daytime drowsiness, cognitive impairments, and an increased risk of accidents.
Treatment options for CSA depend on the underlying cause. In cases where CSA is medication-induced, reducing the dosage or discontinuing the medication may improve CSA. The remedē System, a pacemaker-like implantable device, has been approved by the FDA for moderate to severe CSA. This device stimulates the phrenic nerve, which controls the diaphragm, helping to restore normal breathing patterns during sleep. Continuous positive airway pressure (CPAP) therapy can also be beneficial for individuals with CSA, particularly when caused by heart failure. Additionally, general sleep apnea treatments, such as maintaining a healthy weight, avoiding alcohol and sleeping pills, and sleeping on the side, can be recommended.

Lifestyle changes
Sleep apnea is a condition that affects your breathing while you sleep. It can cause unusual breathing patterns, such as fast breathing that gets deeper, then shallower, until breathing stops before starting again. This condition can lead to serious complications and affect your physical and mental health. Lifestyle changes can help manage the symptoms of sleep apnea and include the following:
Weight loss
Sleep apnea is associated with obesity, and weight loss can help reduce the narrowing or blockage of airways.
Avoid alcohol and certain medications
Alcohol and certain medications, such as opioids and other drugs, can make the symptoms of sleep apnea worse. It is important to consult with a healthcare provider to review any medications that may be contributing to sleep apnea.
Smoking cessation
Quitting smoking can improve overall respiratory health and reduce inflammation, which may help alleviate sleep apnea symptoms.
Sleep position
Sleeping on your back can worsen sleep apnea. Sleeping on your side or elevating your head with extra pillows may help improve breathing during sleep.
Dental devices
Oral appliances, such as a sleep mouth guard or tongue-retaining device, can help keep the throat open and improve breathing during sleep. These devices can be recommended by a dentist or a healthcare provider specialising in sleep disorders.
It is important to note that while lifestyle changes can help manage mild sleep apnea, more severe cases may require additional treatments, such as positive airway pressure machines (CPAP) or surgery. Seeking advice from a healthcare professional is essential to determine the best course of action for managing sleep apnea.

Oral appliances
Sleep apnea is a condition that affects your breathing while you sleep. It can cause you to stop breathing momentarily and prevent you from getting restful sleep. This can lead to serious health complications over time, including high blood pressure, stroke, and atrial fibrillation. Obstructive sleep apnea (OSA) occurs when the muscles in your throat relax, causing the surrounding tissue to press on your windpipe and block air movement. Central sleep apnea (CSA), on the other hand, is caused by the brain failing to signal the body to breathe.
While oral appliances can be effective for some people, they may not be suitable for everyone. For example, those with severe OSA or very low blood oxygen levels may require more immediate and effective treatments such as CPAP therapy. Additionally, oral appliances should not be used by individuals with certain dental conditions, such as jaw joint issues, periodontal disease, or those wearing teeth realignment devices. It's important to consult with a healthcare provider to determine the best treatment option for your specific needs.
There are also other types of oral appliances, such as tongue-retaining devices (TRDs) and rapid maxillary expansion (RME) devices, which are used specifically for children with sleep apnea. A new oral appliance called a tongue muscle stimulation device has been approved by the FDA for treating snoring and mild sleep apnea. This device sends small electric signals to the tongue to strengthen muscle tone and keep the airway open.

Surgery
Sleep apnea is a condition that affects your breathing while you sleep, causing you to periodically stop breathing. This prevents you from getting restful sleep, which can impact your physical and mental health. Typically, sleep specialists will first recommend non-invasive treatments for sleep apnea, such as continuous positive airway pressure (CPAP) therapy or oral devices. However, if these treatments are unsuccessful, surgery may be considered as an option.
The type of surgery recommended will depend on the type of sleep apnea and the patient's unique anatomy. Surgeries for obstructive sleep apnea (OSA) involve reducing physical blockages, such as by removing tissue or adjusting the placement of the jaw or tongue. One such surgery is UPPP, which involves removing or shrinking parts of the tonsils, uvula, and soft palate. Maxillomandibular advancement, which involves dividing the chin bone into two parts to allow the tongue to move forward, is another option. This procedure has a shorter recovery time but is usually less effective. Genioglossus advancement, which tightens the tendons at the front of the tongue to prevent it from interfering with breathing, is often done alongside other procedures.
For patients with OSA, there are also two nerve stimulation surgeries available. Hypoglossal nerve stimulation (HNS) involves implanting a device that feeds an electrical current to the tongue, causing it to stiffen or move forward and clear the airway. This procedure can be done as an outpatient surgery, and the voltage can be adjusted to the patient's needs. The other option is Inspire surgery, which involves a small implantable pacemaker-like device that stabilizes the throat by providing gentle stimulation to the throat muscles, allowing the airway to remain open.
There is only one surgical procedure available for central sleep apnea (CSA), where breathing lapses are caused by problems with signals from the brain stem rather than physical blockages. This procedure involves electrically stimulating a nerve that leads past the lungs to the diaphragm.
All surgeries carry risks, and patients with sleep apnea may be at a higher risk of certain complications, especially those related to anesthesia. Therefore, it is important to consult with a doctor to explore all available treatments and risks before considering surgery.
