As the name suggests, OHS usually affects people who are overweight or obese. Hypoventilation means that breathing is too shallow or too slow. Because your body needs to work harder to breathe, your respiratory system* becomes exhausted and you end up with carbon dioxide levels that are too high and oxygen levels that are too low. If you have OHS you might be experiencing: - shortness of breath - Excessive Daytime Sleepiness (EDS) - morning headaches - depression. *Your respiratory system is made up of all the organs in your body that help you to breathe. ## Share [Share via Email ](mailto:?subject=What+is++Obesity+hypoventilation+syndrome%28OHS%29%3F+%7C+ResMed&body=https%3A%2F%2Fwww.resmed.asia%2Fen-bn%2Fconsumer%2Fdiagnosis-and-treatment%2Frespiratory-care%2Fohs%2Fwhat-is-ohs) [![](https://www.resmed.asia/hubfs/Res-Med%20B2C%202019/Social%20Icons/icon-social-print1.png) ](https://www.resmed.asia/en-bn/consumer/diagnosis-and-treatment/respiratory-care/ohs/what-is-ohs#) [Share via Facebook ](https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.resmed.asia%2Fen-bn%2Fconsumer%2Fdiagnosis-and-treatment%2Frespiratory-care%2Fohs%2Fwhat-is-ohs) [Share via Twitter ](https://twitter.com/intent/tweet?url=https%3A%2F%2Fwww.resmed.asia%2Fen-bn%2Fconsumer%2Fdiagnosis-and-treatment%2Frespiratory-care%2Fohs%2Fwhat-is-ohs&text=What+is++Obesity+hypoventilation+syndrome%28OHS%29%3F+%7C+ResMed) [Share via LinkedIn ](https://www.linkedin.com/shareArticle?mini=true&url=https%3A%2F%2Fwww.resmed.asia%2Fen-bn%2Fconsumer%2Fdiagnosis-and-treatment%2Frespiratory-care%2Fohs%2Fwhat-is-ohs&title=What+is++Obesity+hypoventilation+syndrome%28OHS%29%3F+%7C+ResMed&summary=+Obesity+hypoventilation+syndrome) [Share via Pinterest ](https://www.pinterest.com/pin/create/button/?url=https%3A%2F%2Fwww.resmed.asia%2Fen-bn%2Fconsumer%2Fdiagnosis-and-treatment%2Frespiratory-care%2Fohs%2Fwhat-is-ohs) ## More OHS [ Why is treatment important? ** ](https://www.resmed.asia/en-bn/consumer/diagnosis-and-treatment/respiratory-care/ohs/why-is-treatment-important) OHS places a lot of strain on your organs and can affect your ability to do some of the ...
