Understanding Blood Sugar Levels
Blood sugar levels refer to the amount of glucose present in the blood at any given time. Glucose is a type of sugar that serves as the primary source of energy for the body's cells. Maintaining a healthy balance of blood sugar levels is crucial for overall health and well-being. The body regulates blood sugar levels through a complex process involving the pancreas, liver, and other organs.
The normal blood sugar range is typically between 70 and 140 milligrams per deciliter (mg/dL). Levels below 70 mg/dL are considered low blood sugar, or hypoglycemia, while levels above 140 mg/dL are considered high blood sugar, or hyperglycemia. Factors such as diet, exercise, and medication can affect blood sugar levels, making it essential to monitor and manage them regularly.
For instance, consuming a meal high in carbohydrates can cause a spike in blood sugar levels, while engaging in physical activity can help lower them. Certain medications, such as insulin and oral hypoglycemic agents, can also impact blood sugar levels. Understanding how these factors interact with blood sugar levels is vital for maintaining a healthy balance.
