What Causes My Hypercapnia?


Recently I’ve had a couple of times waking up all of a sudden midnight. I woke up, feeling kind of hot and irritable and uneasy. I wanted to take deep breath and even I wanted to open the window. I tried to calm down, and in like twenty minutes I feel much better, and went to sleep again. I think I was lack of oxygen, that’s why I woke up. But I’m a healthy young woman, I don’t have lung problem, how come I got lack of oxygen?


When you wake up because of being short of air, we’ll suggest you have a checkup by your doctor. There’re a few underlying diseases that may cause hypercapnia condition, let’s first make sure you are ok with your lung and bronchus.

Aside from lung or bronchus disease, there are other conditions that can lead to high levels of carbon dioxide and low level of oxygen in the blood during sleep.

  • Drug overdose, like with an opioid or benzodiazepine
  • Brainstem stroke
  • Hypothermia
  • Certain metabolic disorders (for example, low phosphate and magnesium levels in the bloodstream)
  • Certain muscle or nervous system disorders like encephalitis, muscular dystrophy, ALS, or myasthenia gravis

Some tests will help to diagnose.
