Answer:
I would explain that Dan has no symptoms because his diabetes is not in an advanced and uncontrolled state.
Step-by-step explanation:
Type 2 diabetes is usually a silent disease, which does not allow people to experience any symptoms unless it is already very advanced and uncontrolled. Dan did not feel any symptoms, because the disease is still starting in his body, which facilitates treatment and control. This type of obesity develops from incorrect diet and physical inactivity, but it is possible to control it and live normally with it, mainly in cases like Dan's, which are starting.
