Sleep apnea obstructive
Informed by recognized medical guidance
Overview
Obstructive sleep apnea is a condition where your breathing repeatedly stops and starts during sleep because your throat muscles relax and block your airway. This interrupts your sleep and lowers oxygen levels in your body, which can affect your health and how you feel during the day.
Key facts
- It is a common sleep disorder that can affect people of all ages, but it is more common in adults.
- The pauses in breathing can happen many times each night, even hundreds of times.
- Untreated sleep apnea increases the risk of high blood pressure, heart disease, and stroke.
Yes, obstructive sleep apnea is quite common. It is estimated that about 1 in 5 adults have mild sleep apnea, and about 1 in 15 have moderate to severe sleep apnea.
It can affect anyone, but it is more common in people who are overweight, over age 40, have a large neck circumference, or are male. However, women and children can also have sleep apnea.
Symptoms
- Having difficulty breathing while awake
- Chest pain or pressure
- Feeling like you are going to faint or passing out
- Sudden, severe headache or vision changes
- ⚠Witnessed breathing pauses that last more than 10 seconds and occur frequently
- ⚠Severe daytime sleepiness that makes driving or operating machinery dangerous
- ⚠Worsening symptoms despite using a CPAP machine (continuous positive airway pressure) if prescribed
Common symptoms
- Loud snoring, often with gasping or choking sounds
- Waking up feeling tired or with a headache
- Excessive daytime sleepiness, such as falling asleep while reading or driving
- Waking up frequently during the night to urinate
- Mood changes, irritability, or feeling depressed
Symptoms in children
- Snoring, but it may be quieter than in adults
- Restless sleep or sleeping in unusual positions
- Bedwetting
- Daytime sleepiness or trouble paying attention
- Behavioral problems, such as hyperactivity or poor school performance
Symptoms in older adults
- Sleepiness during the day may be less noticeable, but sleep quality is poor
- Frequent waking during the night
- Confusion or memory problems
- Increased risk of falls or accidents due to sleepiness
Causes
Main causes
- The muscles in the back of your throat relax too much during sleep, causing the soft tissue (such as the soft palate and tongue) to collapse and block the airway.
- This blockage reduces airflow and can stop breathing for 10 seconds or longer, until your brain senses the lack of oxygen and wakes you up briefly to reopen the airway.
Risk factors
- Excess weight or obesity, especially around the neck
- Being over age 40
- Being male
- Having a family history of sleep apnea
- Smoking or using alcohol or sedatives before bed
- Narrowed airway due to large tonsils, a thick neck, or a small jaw
When to see a doctor
See a doctor urgently if:
- If you or someone you witness stops breathing during sleep for more than 10 seconds while you are sleeping, and this happens many times
- If you feel excessively sleepy during the day and it affects your safety or ability to function
Book a routine appointment if:
- If you snore loudly most nights and wake up feeling tired
- If you have high blood pressure that is hard to control
- If your partner reports that you gasp, choke, or stop breathing during sleep
Diagnosis
A healthcare provider will ask about your symptoms, sleep history, and risk factors. They may also examine your mouth, nose, and throat. The most accurate way to diagnose sleep apnea is through a sleep study, which can be done at a sleep center or at home with a portable monitor.
Tests that may be done
- Home sleep apnea test (HSAT) – a simple device you wear overnight to measure your breathing, oxygen levels, and heart rate
- Polysomnography – a more detailed sleep study done in a sleep center, which monitors brain waves, eye movements, heart rate, breathing, and oxygen levels
What to expect at your appointment
If you have a home sleep test, you will be given instructions on how to use the device. It is non-invasive and you sleep in your own bed. For an in-lab study, you will spend a night in a comfortable room with sensors attached to your body. The results will help your doctor determine if you have sleep apnea and how severe it is.
Treatment
Treatment for sleep apnea aims to keep your airway open during sleep so you can breathe normally. The most common and effective treatment is a CPAP (continuous positive airway pressure) machine, which delivers a steady stream of air through a mask. Lifestyle changes and other treatments can also help.
Self-care at home
- Lose weight if you are overweight – even a 10% reduction can improve symptoms
- Sleep on your side instead of your back
- Avoid alcohol and sedatives before bed
- Treat nasal allergies if they block your nose
- Maintain a consistent sleep schedule
Medical treatments
Your doctor may prescribe a CPAP machine, which is the standard treatment for moderate to severe sleep apnea. Other options include oral appliances (mouthpieces) that reposition your jaw or tongue to keep the airway open. For mild cases, positional therapy or weight loss may be enough. Always follow your doctor’s advice regarding which treatment is right for you.
When is surgery considered?
Surgery may be considered if other treatments fail, or if there is a structural problem such as enlarged tonsils or a deviated septum. Types of surgery include removing extra tissue from the throat or repositioning the jaw. Surgery is not a first-line treatment and is only recommended after a full evaluation.
Living with this condition
Living with sleep apnea often means using a CPAP machine every night. Many people get used to it and feel much more rested and alert during the day. It may take a few weeks to adjust, but sticking with it is important for your health.
Lifestyle tips
- Use your CPAP machine every night, even during naps
- Keep your mask and machine clean to avoid infections
- Avoid alcohol and heavy meals before bedtime
- Exercise regularly to help with weight management and overall health
Diet and exercise
A balanced diet and regular physical activity can help with weight loss, which may reduce the severity of sleep apnea. Even moderate exercise, like walking for 30 minutes most days, can improve your sleep quality and energy levels.
Mental health and emotional wellbeing
Sleep apnea can cause mood changes, irritability, and depression because poor sleep affects your brain. With treatment, these symptoms often improve. If you feel overwhelmed or sad, talk to your healthcare provider or a counselor. You are not alone.
Prevention
While you cannot always prevent sleep apnea, you can reduce your risk by maintaining a healthy weight, avoiding smoking, and limiting alcohol. If you have mild symptoms, these steps may also keep it from getting worse.
Vaccines
Sleep apnea is not prevented by vaccines.
Complications
If left untreated
- High blood pressure (hypertension)
- Heart disease, including heart attack or stroke
- Type 2 diabetes
- Daytime sleepiness, which can lead to accidents
- Worsening of existing conditions like asthma or atrial fibrillation
Long-term outlook
With proper treatment, most people with sleep apnea can reduce their symptoms, improve their sleep quality, and lower their risk of complications. Many people feel more energetic, happier, and healthier. It is a condition that can be managed well, so there is good reason to be hopeful.
