### High Blood Sugar Without Diabetes Yes, you can have high blood sugar levels even if you don’t have diabetes. This often happens after eating foods that are high in sugar or carbohydrates. For people without diabetes, a normal fasting blood glucose level is between 70 and 100 milligrams per deciliter (mg/dL). After eating, it can rise to about 140 mg/dL within two hours. #### Why Does This Happen? When you eat, your body breaks down the food into glucose, which is a primary source of energy. This glucose enters your bloodstream and is transported to your organs and tissues. After a meal, it’s normal for your blood glucose levels to spike as your body processes the new supply of energy. #### Symptoms of High Blood Sugar Even without diabetes, you might feel the effects of high blood sugar, sometimes referred to as a “sugar rush.” Symptoms can include increased energy or alertness, but this feeling is usually short-lived. You might also experience a “crash” about an hour after eating, leading to tiredness or a lack of energy. #### When to Be Concerned If you frequently experience symptoms of high blood sugar after meals, it’s a good idea to talk to a healthcare professional. This could indicate a risk of diabetes or other issues with blood glucose regulation. Additionally, other factors like stress, anxiety, and certain medical conditions can also affect your blood sugar levels. #### Conclusion High blood sugar isn’t exclusive to people with diabetes. It’s a normal response to eating, especially sugary or carb-heavy foods. However, if you notice frequent or severe symptoms, it’s important to seek medical advice to rule out any underlying conditions.
