What Causes Low Oxygen Levels At Night
Depends on cause...: Most often, this is related to obstructive sleep apnea. This is when your airway becomes "floppy" while sleeping. The airway closes and no air can pass into the lungs.

Particularly if treating the low with food, this counter regulatory response to hypoglycemia can make blood sugar high afterwards. It can happen to some degree even without food. Over treating the low is usually the reason for very high sugars after a low. ...Read more
