It is reasonable to think that after a person has good blood sugar control, this means managing diabetes. But that's not the case.
People with type 1 diabetes can not make their insulin, so they will always need to take insulin shots every day.
The answer is not as clear for people with type 2 diabetes. Occasionally when people discover it for the first time, they start immediately on tablets or insulin. If a person works hard to control diabetes with diet and exercise, then he can reduce the need for medication and prevent it from taking it completely. Until the person is able to keep blood sugar levels normal with diet and exercise, medication is not needed.
However, type 2 diabetes changes over time. Changes can be fast or slow, but it does change. This means that even if a person stops taking the medicine for a while, then he has to start taking it in the future. If someone is taking medication to keep blood sugar normal, it is important to take it to reduce the chances of heart disease and other health problems.
