Yes, hypochochondria can be related to anxiety, in fact it is a sort of anxiety. I was the diagonosed 3 years ago with hypochochondria, after thinking for 6 months that I had some sort of dangerous nerve disease. After getting a cat scan done as well as blood tests and found out that I had absolutly nothing wrong with me, I decided to somewhat cure my hypochochondria alone. To tell you the truth it wasn't easy, but try reading, spending alot of time with the people you love, anything that will get your mind off "health problems". Helped for me
Anyways hope it works for you as well.
