6. Weight gain or obesity
Obesity and sleep apnea are linked. Sleep apnea sufferers are more likely to be overweight. This is because of fat depositions with the soft tissue of the mouth and neck. With sleep apnea, the soft tissue in the throat and mouth area blocks the airway. If you have more soft tissue, it is more likely this area will be blocked. Even if you are naturally predisposed to sleep apnea, being overweight will cause it to be more severe. Lacking a proper night of sleep is likely to make you gain weight. When sleepy, you are more likely to eat to try and stay awake or get energy. This may lead to a cycle of added weight gain.
