For many veterans, health challenges arise as a direct result of their time in service.
Among these challenges, respiratory issues, especially asthma, are commonly reported.
However, there’s another condition, obstructive sleep apnea (OSA), that’s gaining attention for its connection to asthma.
This link is not just vital for a veteran’s well-being but also plays a pivotal role in determining VA benefits.
This article aims to shed light on both asthma and OSA, exploring their connection and its significance for veterans, ensuring they’re equipped with knowledge and can access the benefits they rightfully deserve.
A Brief Overview of Asthma
Asthma is a respiratory condition that affects the airways in the lungs.
When someone has asthma, their airways can become inflamed and swollen, making it harder to breathe.
Here’s a closer look at this condition:
Definition and Impact on the Lungs
Asthma primarily affects the bronchial tubes, which are the passages that allow air to enter and exit the lungs.
Inflammation narrows these tubes, restricting airflow and leading to common asthma symptoms.
Symptoms
- Shortness of breath: This might be especially noticeable during physical activity or at night.
- Wheezing: A whistling or squeaky sound when breathing.
- Coughing: Often worse at night or early in the morning, making it hard to sleep.
- Tightness in the chest: It can feel like something is squeezing or sitting on your chest.
Daily Challenges Faced by Those with Asthma
Asthma can make certain jobs more difficult, especially if they involve physical activity or exposure to irritants.
Physical activities can trigger asthma symptoms for some people.
Even everyday activities, like climbing stairs or playing with children, can become challenges when asthma symptoms flare up.
For veterans, understanding asthma is crucial.
Many experience this condition due to exposures during their service, making it a significant concern when discussing VA benefits and overall health.
A Brief Overview of Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea, commonly referred to as OSA, is a sleep disorder where breathing repeatedly stops and starts during sleep.
This is due to a blockage of the airway, usually when the soft tissue at the back of the throat collapses and closes during sleep.
Here’s a deeper dive into OSA:
Definition and Impact on Breathing
OSA occurs when the muscles in the back of your throat fail to keep the airway open, despite the effort to breathe.
This interruption in breathing can happen several times a night, leading to a decrease in oxygen in the blood, which can have serious health implications if untreated.
Symptoms
- Loud snoring: While not everyone who snores has OSA, snoring is frequently associated with the condition.
- Abrupt awakenings: Often accompanied by gasping or choking.
- Morning headaches: Due to the lower levels of oxygen in the blood.
- Excessive daytime sleepiness: This happens because the sleep cycle is constantly interrupted.
- Difficulty concentrating during the day: A result of the lack of restful sleep.
- Mood changes: Such as depression or irritability, often due to sleep deprivation.
Challenges in Daily Life
Sleep deprivation can make driving or operating machinery dangerous.
Day-to-day tasks can become more challenging when you’re constantly tired.
Mood swings and fatigue can strain personal relationships.
The Relationship Between Asthma and Obstructive Sleep Apnea
There’s a growing body of evidence suggesting that asthma and obstructive sleep apnea (OSA) often coexist in the same individual.
While it might seem that the two are unrelated at first glance, several factors connect these conditions:
Shared Risk Factors
- Inflammation: Both asthma and OSA involve inflammation. For asthma, it’s the inflammation of the bronchial tubes, and for OSA, inflammation can cause the throat muscles to relax more than usual during sleep.
- Obesity: Being overweight can contribute to both asthma and OSA. Excess weight might intensify inflammation or increase the risk of airway obstructions.
- Respiratory Changes: People with asthma may experience changes in their airways, making them more susceptible to the disruptions in breathing seen in OSA.
Medical Findings
Research has shown that individuals with asthma face an almost 40% greater risk for sleep apnea than those without asthma.
Chronic or intermittent use of systemic steroids, common in asthma treatment, might increase the tendency for airway collapse during sleep, which is a hallmark of OSA.
Compounding Effects
OSA can worsen the symptoms of asthma, and vice versa. Poor sleep quality from OSA can lead to increased inflammation, making asthma symptoms more severe.
The presence of OSA might make it harder to manage asthma, as disrupted sleep can affect how the body responds to asthma medications.
Why is Obstructive Sleep Apnea Linked to Asthma?
While it’s established that there’s a connection between asthma and obstructive sleep apnea (OSA), it’s essential to dive deeper into the reasons behind this link.
Both conditions impact the respiratory system, but how exactly does one condition influence the other?
Medication Implications
- Bronchodilators: These are commonly prescribed for asthma to help open the airways. However, they can also relax the muscles around the throat. For someone predisposed to OSA, this relaxation can increase the risk of airway obstruction during sleep.
- Oral or Inhaled Steroids: These medications reduce inflammation in asthma patients. But long-term use may weaken the upper airway muscles, leading to increased chances of airway collapse during sleep.
- Physiological Triggers
- Airway Inflammation: Both asthma and OSA are characterized by inflammation. Asthmatic inflammation can make the airways more sensitive and reactive, which could increase the risk of nocturnal breathing disruptions.
- Reduced Lung Function: Over time, chronic asthma can lead to changes in lung function, making it easier for obstructions to occur, especially during the relaxed state of sleep.
- Respiratory Patterns:
- Breathing Disruptions: Asthma can cause irregular breathing patterns, and over time, these irregularities might predispose an individual to the stop-and-start breathing patterns characteristic of OSA.
- Environmental Factors:
- Allergens: Both asthma and OSA can be triggered or worsened by environmental allergens like dust mites or pet dander. These allergens can cause inflammation in both the lungs and the airways.
- Reflux: Gastroesophageal reflux disease (GERD), common in asthma patients, can exacerbate OSA symptoms. The reflux can cause direct irritation of the airway or lead to increased nighttime awakenings, which can then provoke asthma symptoms.

Understanding the intricate relationship between asthma and obstructive sleep apnea (OSA) isn’t just about connecting two medical conditions—it’s about recognizing the broader implications for the health and well-being of our nation’s veterans. For those who have served and sacrificed, the VA disability rating process can often be a path to validation and support, ensuring veterans receive the care and benefits they rightfully deserve.
