Sleep Apnea & Diagnosis
What Is Sleep Apnea? Symptoms, Causes, Risks and CPAP Treatment Explained
Jun
Sleep apnea is a common sleep disorder in the United States. Many people have it and do not realize it.
It happens when breathing repeatedly stops and starts during sleep. These pauses reduce oxygen levels and disturb normal sleep.
This guide explains sleep apnea, common symptoms, possible causes, risks, and how CPAP therapy is used to treat it.
What Is Sleep Apnea?
Sleep apnea is a breathing disorder that occurs during sleep.
The most common type is Obstructive Sleep Apnea, also called OSA. It happens when the throat muscles relax too much and block the airway.
These breathing pauses can last several seconds and may happen many times each night.
Common Symptoms of Sleep Apnea
You may have sleep apnea if you notice:
- Loud snoring
- Gasping or choking during sleep
- Pauses in breathing
- Daytime fatigue
- Morning headaches
- Trouble concentrating
- Mood changes
If these symptoms are present, a medical evaluation may be helpful.
What Causes Sleep Apnea?
Sleep apnea often occurs when the airway collapses during sleep.
Risk factors may include:
- Excess weight
- Larger neck size
- Family history
- Smoking
- Alcohol use
- Nasal congestion
Why Untreated Sleep Apnea Can Be Serious
When breathing stops repeatedly at night, oxygen levels drop. Over time, untreated sleep apnea may be linked to:
- High blood pressure
- Heart disease
- Stroke
- Type 2 diabetes
- Chronic fatigue
- Reduced focus
A healthcare provider can determine if further testing is needed.
How Is Sleep Apnea Diagnosed?
Sleep apnea is diagnosed through a sleep study.
This may be done in a sleep lab or through a physician prescribed home sleep test.
The test measures breathing, oxygen levels, heart rate, and sleep patterns.
What Is CPAP Therapy?
CPAP stands for Continuous Positive Airway Pressure.
A CPAP machine sends a steady flow of air through a mask to help keep the airway open while you sleep.
Types of machines include:
- Standard CPAP
- Auto CPAP
- BiPAP
Mask styles include nasal masks, full face masks, and nasal pillow masks.
Is CPAP Therapy Effective?
When used correctly and consistently, CPAP therapy can reduce breathing interruptions and improve sleep quality.
Comfort and proper mask fit are important for successful therapy.
Do You Need a Prescription for a CPAP Machine in the U.S.?
Yes. CPAP, APAP, and BiPAP machines require a valid prescription from a licensed healthcare provider in the United States.
CPAP masks and replacement parts do not require a prescription.
When Should You Speak With a Doctor?
If you feel constantly tired, snore loudly, or experience breathing pauses during sleep, speak with a qualified healthcare professional.
Early diagnosis and treatment can improve sleep and overall health.
