How to Recognize and Treat Hypoglycemia and Hyperglycemia


Effective diabetes management involves maintaining blood sugar levels within a target range. Deviations from this range can lead to hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar), each with distinct symptoms and risks. Understanding how to recognize and promptly treat these conditions is crucial to prevent complications and maintain health. This detailed blog, backed by’s commitment to comprehensive health education, explores the signs, causes, and treatments of hypoglycemia and hyperglycemia, providing essential knowledge for individuals with diabetes and their caregivers.
