With an estimated 25 million US adults aged 30 to 70 living with obstructive sleep apnea, the “simple snoring” label stops making sense fast. The untreated risk jump is stark, with severe OSA raising all cause mortality about 3 fold and driving stroke risk 2.3 times higher, while even common outcomes like depression, diabetes, and motor vehicle crashes show measurable increases. By the end, you will see how one night of breathing disruption can echo through the heart, brain, and everyday work and family life.
Key Takeaways

- OSA patients have 2.3-fold higher risk of stroke
- Severe OSA triples coronary heart disease risk
