The simplest meaning of “dysfunctional” is “doesn’t work right.” Dysfunction comes in differing degrees. Some dysfunctional things or people grate on one’s nerves just a little bit—like a squeaky door. But when a situation involves people who must relate to each other or when circumstances are perceived as intolerable, you must do one of two things. You can modify this situation—at least partially—or remove yourself. For example, when a dysfunctional organ or system of your body results in disease, you had better see a doctor sooner rather than later if you want to survive.
