Groundbreaking studies might reveal the trick to longevity in humans
Sleep apnea is a serious sleep condition that causes you to stop and start breathing while you sleep. If it goes untreated it can cause serious health problems.
People with sleep apnea, however, often snore much, much louder than normal. They may also gasp or choke, and they often sleep restlessly.
Research suggests sleep apnea is a lot more common than we might think: according to the American Academy of Sleep Medicine, it could affect up to 12% of US adults.
As many as 80% of sufferers go undiagnosed. Many people don’t know they have apnea, because it only occurs during sleep.
Obstructive sleep apnea occurs when your airways become blocked while you sleep, usually because the soft tissue at the back of your throat has collapsed.
While your airways are blocked, your diaphragm and chest muscles have to work extremely hard to open them. This can prompt loud gasps or jerking movements.
Central sleep apnea is more common in people with serious health conditions, in particular people who suffer from a neuromuscular disease, such as ALS.
The third type of apnea is complex sleep apnea, which is diagnosed when someone suffers from both obstructive sleep apnea and central sleep apnea.
Most people do not notice their first symptoms of sleep apnea, because they are asleep. More often it is their partner that alerts them to the symptoms.
People with central sleep apnea usually report waking up a lot during the night, otherwise known as insomnia. People with either type may choke themselves awake.
Symptoms may be less obvious in children, but they include sweating a lot at night, trouble swallowing, and sleepiness, which might be mistaken for laziness at school.
If there is no other obvious cause for your symptoms, the doctor will usually review your medical history and order tests to find out what is going on.
If you go to your doctor with symptoms of sleep apnea, they will normally try to rule out any other potential causes for your symptoms first.
If, on the basis of their findings, the doctor suspects you have sleep apnea, they may refer you to a sleep specialist for a sleep study.
The purpose of the sleep study, which can be done at home, is to determine, among other things, whether your breathing stops or slows down while you are asleep.
Based on the number of sleep apnea events you had in an hour of the study, the doctor may diagnose you with mild, moderate, or severe sleep apnea.
The doctor may also order further tests to determine whether you have an underlying health condition that could be causing your sleep apnea.
For people suffering with mild sleep apnea, it may be a sufficient treatment to lose weight, stop smoking, or find a treatment for nasal allergies.
In more serious cases, the doctor may prescribe a continuous positive airway pressure (CPAP) machine to help you regulate your breathing while you sleep.
If none of these treatments work, your doctor may recommend one of a number of possible surgeries, such as tissue removal, tissue shrinkage, or jaw repositioning.
If it goes untreated, sleep apnea can have serious complications. For starters, it causes daytime fatigue, which in turn makes it more likely for people to have accidents.
The drop in blood oxygen levels while you sleep also puts the cardiovascular system under stress. Sufferers are therefore at a higher risk of recurrent heart attacks or stroke.
Obstructive sleep apnea can cause people to have issues with certain medications or after major surgery because they are more likely to have trouble breathing.
Finally, sleep apnea has been shown to impact the results of liver function tests. Sleep apnea sufferers have livers that are more likely to show signs of scarring.

Common symptoms include snoring, restlessness while sleeping, and fatigue during the day. Sufferers may also experience headaches and mood disorders.
There are three different types of sleep apnea, and they all have slightly different symptoms. The most common type is obstructive sleep apnea.
When it comes to sleep conditions, there are some that we often hear about. Insomnia, for example, often finds its way into conversation, as does narcolepsy and even restless legs syndrome. A lesser-known condition is sleep apnea, which causes its sufferer to stop and start breathing while they sleep. The symptoms of sleep apnea vary from person to person, but the most common symptom is unusually loud snoring.
Of course, many people snore and it doesn't necessarily warrant a trip to the doctor. If left untreated, however, sleep apnea can have serious complications and can even be fatal.
