When someone is newly diagnosed with type 1 diabetes, one of the first questions they ask is: what should my blood sugar levels be? What counts as normal, high, or low? Blood sugar levels vary from person to person because each body is unique. Factors such as age, personal health history, food intake, medication, activity levels, and even stress can influence how your body processes glucose.While health organizations provide general guidelines for people without diabetes, target blood sugar levels for someone with type 1 diabetes are individualized. Your healthcare provider will help set goals that fit your lifestyle, age, and overall health needs, making management safer and more effective.What Is Blood Sugar?When we eat, the carbohydrates in our food are broken down into glucose, the body’s primary energy source. Glucose enters the bloodstream, and the hormone insulin helps move it into cells, providing fuel for muscles and organs. When this process works well, your blood sugar remains in a healthy range, giving your body enough energy without leaving excess sugar circulating in the blood.For people with type 1 diabetes, the body doesn’t produce enough insulin naturally, so glucose can build up in the bloodstream. This makes regular monitoring of blood sugar levels essential.What Is a Normal Blood Sugar Reading for Type 1 Diabetes?Health organizations like the American Diabetes Association (ADA) and the Centers for Disease Control and Prevention (CDC) provide guidance:Before meals (fasting):80–130 mg/dL (4.4–7.2 mmol/L) for teens and adults100–180 mg/dL (5.5–10.0 mmol/L) for children 6–12 years100–180 mg/dL (5.5–10.0 mmol/L) for children under 6Two hours after a meal:Less than 180 mg/dL (10 mmol/L)These ranges are general guidelines. Your healthcare provider may adjust your targets based on your age, other health conditions, pregnancy, or lifestyle. Understanding these numbers and how they respond to food, activity, and medication is key to staying healthy.When and How Should I Check My Blood Glucose?Most people with type 1 diabetes check their blood glucose multiple times a day to ensure their levels stay within their target range. How often you check depends on your treatment plan and daily routine.Common methods include:Blood glucose meter: Measures glucose from a small finger-prick blood sample. This method is quick and widely used at home.Continuous Glucose Monitoring (CGM): A tiny sensor under the skin tracks glucose levels every few minutes, providing real-time readings throughout the day and night. CGM is especially useful for people on insulin or who have frequent low blood sugar episodes.A1C test: A lab test that measures your average blood glucose over the past three months. Most people with diabetes take this test at least twice a year, but your provider may recommend it more often if you are not meeting your treatment goals.Tips for Tracking Blood SugarKeep a log: Note your blood sugar readings, meal times, and physical activity to spot patterns.Check before and after meals: This helps understand how different foods affect your glucose.Monitor trends: Don’t focus only on single readings—look at patterns over days or weeks.Work closely with your healthcare team: They can help adjust insulin doses or other treatments based on your tracking.Regular monitoring and understanding your numbers can help prevent complications, manage symptoms, and improve your quality of life. Tracking blood sugar is not just about numbers, it’s about learning how your body responds and making informed choices every day.
