When people hear about Obstructive Sleep Apnea (OSA), they often associate it with being overweight. While excess weight is an important risk factor, you can have obstructive sleep apnea even if you are not overweight.
OSA occurs when the upper airway becomes partially or completely blocked during sleep, repeatedly interrupting normal breathing. Body weight is only one factor that can contribute to this airway obstruction.
Why Can Non-Overweight People Develop Sleep Apnea?
Several factors can increase the risk of OSA even in people with a normal body weight.
Airway anatomy:
Some people naturally have a narrower upper airway or anatomical features that make the airway more likely to collapse during sleep.
Jaw structure:
A smaller or recessed jaw can reduce the space available for the tongue and other tissues, potentially increasing airway obstruction.
Nasal blockage:
Conditions that make nasal breathing difficult may contribute to or worsen sleep-disordered breathing.
Sleeping position:
Some people experience more airway obstruction when sleeping on their back. This is known as positional sleep apnea.
Age and genetics:
Changes in airway muscle tone with age and individual genetic or anatomical characteristics can also influence OSA risk.
Can You Have Sleep Apnea with a Normal BMI?
Yes. A normal BMI does not rule out obstructive sleep apnea.
This is important because people who are not overweight may overlook symptoms such as loud snoring, witnessed pauses in breathing, unrefreshing sleep or excessive daytime tiredness, assuming that sleep apnea cannot affect them.
If these symptoms are present, an evaluation by an obstructive sleep apnea doctor may be appropriate regardless of body weight.
How is OSA Diagnosed?
If your doctor suspects sleep apnea, a sleep study or polysomnography may be recommended. During this test, several parameters such as breathing, oxygen levels, heart activity and brain activity are monitored while you sleep.
A sleep study can help determine whether you have OSA and assess its severity.

When Should You See a Sleep Specialist?
If you regularly snore, wake up feeling unrefreshed, experience excessive daytime sleepiness, or someone notices pauses in your breathing during sleep, don’t assume that your weight rules out sleep apnea.
A pulmonologist and sleep specialist can evaluate your symptoms and determine whether a sleep study or further assessment is needed.
For comprehensive evaluation and management of sleep disorders, patients can also visit a Comprehensive Sleep Center in Salem.

Wrapping up…
Yes, obstructive sleep apnea can affect people who are not overweight. Weight is only one of several risk factors. Airway anatomy, jaw structure, nasal problems, sleeping position, age and other factors can also contribute to OSA.
If you have symptoms suggestive of sleep apnea, consider getting evaluated rather than assuming that your normal weight protects you from the condition.
