RORY: Can brains hurt?
LORELAI: Yes, it’s hypochondria hour.
Hypochondria is a condition where a person is overly worried about having a serious illness, and become extremely concerned about even mild symptoms in the fear that they are a sign of a life-threatening condition. In many cases, their anxiety about their health actually produces the symptoms they are worried about, such as headaches, stomach pains, dizziness, weight loss, or fatigue. It is now called “illness anxiety disorder”.
