Normal Blood Sugar Levels and Variations
Normal blood sugar levels typically range from 70 to 140 milligrams per deciliter (mg/dL) after eating, and less than 100 mg/dL when fasting. However, these levels can fluctuate throughout the day due to various factors such as meals, physical activity, and sleep. For instance, blood sugar levels usually peak after meals, especially those high in carbohydrates, and can also be affected by stress, certain medications, and hormonal changes.
Hyperglycemia, or high blood sugar, occurs when the body has too much glucose in the bloodstream. This can happen when the body is unable to produce enough insulin, a hormone that regulates blood sugar levels, or when the body becomes resistant to insulin. Fasting hyperglycemia, which occurs when blood sugar levels are high after an overnight fast, can be a sign of an underlying medical condition such as type 2 diabetes.
Blood glucose levels can also be affected by physical activity, with levels typically decreasing after exercise. However, levels can also rise after intense or prolonged physical activity, especially if the body is not able to produce enough insulin to meet the increased glucose demands.
Factors Affecting Blood Sugar Levels
Type 2 diabetes is a medical condition that affects the way the body regulates blood sugar levels. People with type 2 diabetes are often unable to produce enough insulin, or their bodies become resistant to insulin, leading to high blood sugar levels. Other factors that can affect blood sugar levels include certain medications, such as steroids and certain psychiatric medications, as well as hormonal changes, such as those that occur during pregnancy or menopause.
