Adults who are 20 years or older will have blood sugar levels that range between less than 100-180 mg/dL over the course of a day. When you wake up in the morning, your fasting blood sugar should be at its lowest because you haven’t consumed food for about eight hours. If you’re an adult and struggling with glucose control, your healthcare provider can help you develop a treatment plan to manage your blood sugar better.
Blood glucose levels outside the ranges listed above are categorized as either high or low blood sugar. Blood sugar levels are considered high if they’re over 130 mg/dL before a meal or 180 mg/dL within one to two hours after a meal
