Recognizing the Symptoms of High Blood Sugar vs Low: A Comprehensive Guide | symptoms of high blood sugar vs low
Blood sugar regulation is a critical aspect of overall health, and recognizing the symptoms of high and low blood sugar levels is essential for timely intervention and proper treatment. Hyperglycemia, or high blood sugar, and hypoglycemia, or low blood sugar, can have serious consequences if left uncontrolled.

Understanding Hyperglycemia and Hypoglycemia
Hyperglycemia occurs when the body has too much glucose in the blood, while hypoglycemia occurs when the body has too little glucose.

In individuals with diabetes, the body either cannot produce enough insulin (type 1 diabetes) or cannot effectively use the insulin it produces (type 2 diabetes). Other conditions, such as pancreatitis and pancreatic cancer, can also affect blood sugar levels.
