Millions of Americans havesleep apnea—a chronic disorder that causes you to stop breathing in your sleep. There are various risk factors that can lead to sleep apnea, including obesity and smoking, but genetics may also play a role.

In extremely rare cases, central sleep apnea can be linked to genetics, but genes are a much more common culprit in obstructive sleep apnea. Some studies estimate that nearly 75% of people with obstructive sleep apnea inherited the disorder in some way.

This article with explore the different types of sleep apnea, how genetics may be involved, and what to expect with a sleep apnea diagnosis.

What Is Sleep Apnea?

Sleep apnea is a chronic condition where your breathing is interrupted as you sleep. These disruptions can last for 10 seconds or more, and occur several times an hour. In severe cases of sleep apnea, your breathing could stop hundreds of times in a single night.

Central vs Obstructive Sleep ApneaThere are three types of sleep apnea—central sleep apnea, obstructive sleep apnea, and complex sleep apnea.Central sleep apneadevelops when the signals that your brain sends to your respiratory system are disrupted. This causes pauses in your breathing.Withobstructive sleep apnea, obesity or abnormal structures in the mouth or throat cause your airway to become partially or even completely blocked. When this happens, your breathing can stop.Complex sleep apneais a combination of both central and obstructive sleep apnea.

Symptoms

The main symptom of sleep apnea is a pause in your breathing during sleep. However, there are a number of other issues that can signal this disorder as well, including:

Diagnosis

A sleep apnea diagnosis is usually made with a sleep study. In this study, called apolysomnograph, you will need to spend several hours asleep in a lab while different measurements of your health are taken. Your heart rate, movements, and breathing patterns will all be observed, and your healthcare provider will use this information to diagnose and rate your level of sleep apnea.

These tests can also provide clues as to what type of sleep apnea you have. Testing your brain waves and nerve signals during your sleep study can identify central sleep apnea.

Is Sleep Apnea Hereditary?

Genetics can play a role in some types of sleep apnea. Central sleep apnea usually has non-genetic causes that are not hereditary. Obstructive sleep apnea, on the other hand, can be linked to genetics in several ways.

Obstructive Sleep Apnea

Unlike central sleep apnea, obstructive sleep apnea is linked togeneticsin several ways.

First, many of the risk factors that can lead to sleep apnea—like high blood pressure and heart disease—carry a hereditary component to them. If you have a family history of conditions that increase your risk for sleep apnea, you should talk to your healthcare provider about any symptoms you might be having.

On top of an increased risk from these inherited conditions, there are also specific genes that have been linked to the development of sleep apnea. These include:

Even though some cases of obstructive sleep apnea are hereditary, genetics are not the only cause. Other causes of sleep apnea include:

What Causes Mild Obstructive Sleep Apnea?

Even without a structural or genetic condition, there are other disorders or diseases that can increase your risk of developing sleep apnea. More than 80% of people with sleep apnea have other medical conditions like:

Lifestyle choices can also put you at risk of developing sleep apnea. Some of these include:

When to Talk to Your Healthcare Provider

There are some symptoms, though, that warrant quicker action. If you have symptoms like severe shortness of breath, confusion,blueish lips or nails, or you wake up with difficulty breathing, you should seekmedical helpright away.

Can Medication Cause Sleep Apnea?

While you can’t control the genetic predisposition to sleep apnea, you can make choices that can help you avoid developing conditions that increase your risk for obstructive sleep apnea (OSA), like obesity andhigh blood pressure.

Some of the things you can do to reduce your risk of developing sleep apnea include:
