That's definitely a word for it. Particularly because if you ever want to scare yourself, try googling symptoms. (Though I did describe it to a friend in order to ask "How do I even do a search for this as a symptom?" and her response was "YOU DON'T. YOU GO TO A DAMN DOCTOR.")

It's more confusing than anything else. If it were a weight issue, why wasn't it happening thirty pounds ago? And because I am rather overweight, I just know that I'm going to have a hard time getting a doctor to look into other reasons and not just stop at the weight as the culprit.
