Blood sugar, or blood glucose, refers to the amount of glucose in your bloodstream. Glucose is a type of sugar that your body uses for energy.
Normal blood sugar ranges can vary depending on several factors, including age, overall health, and time of day.
The American Diabetes Association (ADA) recommends a target range of 70-130 mg/dL for fasting blood sugar levels (measured after 8 hours of not eating) and less than 180 mg/dL after meals.
People without diabetes typically have blood sugar levels that stay within this target range throughout the day.
Blood sugar levels that are consistently too high or too low can be a sign of an underlying health problem, such as diabetes.
Symptoms of high blood sugar levels can include frequent urination, increased thirst, and blurry vision, while symptoms of low blood sugar levels can include shakiness, dizziness, and confusion.
Regular monitoring of blood sugar levels is important for people with diabetes, as it can help them adjust their medication or lifestyle habits as needed to maintain healthy levels.
A healthy lifestyle that includes diet, exercise, and other factors can lower the risk of developing diabetes and other health issues related to high blood sugar.
