Understanding Hyperglycemia and Hypoglycemia
Hyperglycemia, also known as high blood sugar, and hypoglycemia, or low blood sugar, are two conditions that can have serious consequences if left untreated. Hyperglycemia occurs when the body has too much glucose in the blood, while hypoglycemia occurs when the body has too little glucose. Both conditions are closely related to diabetes, a chronic disease that affects the way the body regulates blood glucose levels.
According to the American Diabetes Association, diabetes is a major cause of hyperglycemia and hypoglycemia. When the body is unable to produce enough insulin, a hormone that regulates blood glucose levels, glucose builds up in the blood, leading to hyperglycemia. On the other hand, when the body produces too much insulin, glucose levels drop, leading to hypoglycemia.
Blood glucose monitoring is crucial in recognizing the symptoms of hyperglycemia and hypoglycemia. By regularly checking blood glucose levels, individuals with diabetes can identify patterns and trends, and make adjustments to their diet, exercise, and medication to prevent complications. The Healthline website provides a wealth of information on blood glucose monitoring, including tips on how to use a glucose meter and how to interpret test results.
