Why do i breathe fast when i'm asleep?

Question

According to my boyfriend i breathe very fast when i'm sleeping. When i'm awake, i breathe kind of slow. Why is this?

Answer 1

There are several possibilities for what could be causing this such as a problem with the thyroid (an example only) or something like an issue with the lungs and heart (another example only).

The only way to find out for sure is to see your doctor for further evaluation of the situation to see what they think could be going on.
