Question

what is long term disease ???

Answer 1

A chronic disease is one that (a) sticks with you for a VERY long time, or (b) keeps coming back. So if someone has chronic bronchitis, it means they have bronchitis for more than a week or two or they'll have it for a while and then they'll get it again a few weeks later, then it'll go away again, then it'll come back a few weeks later -- get the idea?

The major problem with a chronic disease is treatment. In many cases it involves changing medication every few months, but it could also involve surgery or other unpleasant treatments like steroids or chemotherapy. Not fun...
