Obstructive sleep apnea (OSA) is a potentially serious disorder that affects millions of people worldwide. OSA is characterized by repetitive pauses in breathing during sleep due to the partial or complete blockage of the airway. If left untreated, OSA can lead to a host of health issues, including excessive daytime sleepiness, fatigue, and depression. But what is the primary cause of OSA?

The Primary Cause: Anatomical Obstruction

When it comes to the primary cause of OSA, the answer lies in anatomical obstruction. The airway can be blocked by a variety of factors, including excess soft tissue or enlarged tonsils or adenoids, foreign objects, or structural abnormalities of the jaw and palate. The most common cause of OSA is an excess soft tissue in the back of the throat that relaxes during sleep and collapses against the airway, blocking airflow.

Other Factors That May Contribute to OSA

In addition to anatomical obstruction, several other factors may contribute to OSA.

1. Being overweight

2. Age

3. Smoking

4. Alcohol

Treatments for OSA

Fortunately, there are a variety of treatments available for OSA. These include lifestyle changes (such as avoiding alcohol and smoking) and various medical devices that help keep the airway open. In severe cases, surgery may be necessary to remove excess tissue or correct structural abnormalities in the airway. As with any medical procedure, it is important to talk to a doctor about the risks and benefits of each option.
