Final answer:
For a diabetic person, good blood glucose level means maintaining controlled blood sugar within a specific target range through lifestyle, diet, and possibly medication or insulin. Abnormally high or low blood sugar levels can have serious health consequences.
Step-by-step explanation:
If you are already diagnosed as diabetic, the goal is to have controlled blood sugar levels. Normal or good blood glucose levels for a diabetic person are generally between 70 and 130 mg/dL before meals, and less than 180 mg/dL two hours after starting a meal. Diabetes is diagnosed when fasting blood glucose levels are 126 mg/dL or higher on two separate tests. For managing type 2 diabetes, treatment typically includes lifestyle modifications, monitoring blood sugar, and possibly medication or insulin injections. It's essential to maintain glucose levels within a target range to prevent complications associated with high blood sugar (hyperglycemia) and low blood sugar (hypoglycemia).
