Understanding Blood Sugar Levels
Blood sugar levels are a critical aspect of our overall health, and maintaining normal levels is essential for preventing complications. Hyperglycemia, or high blood sugar, and hypoglycemia, or low blood sugar, are two conditions that can have significant effects on the body. Hyperglycemia occurs when the body has too much glucose in the blood, while hypoglycemia occurs when the body has too little glucose. Both conditions can be caused by various factors, including diabetes, certain medications, and lifestyle choices.
A blood sugar level chart can help individuals understand what's normal, low, and high. Normal blood sugar levels typically range from 70 to 140 mg/dL, while high blood sugar levels can exceed 180 mg/dL. Low blood sugar levels, on the other hand, can be below 70 mg/dL. It's essential to note that abnormal sweating can be a symptom of both hyperglycemia and hypoglycemia, and individuals with diabetes should be aware of this connection.
