Low Blood Glucose (Hypoglycemia) is more risky, CGM is a game changer

Hypoglycemia (low blood sugar) can be more dangerous than hyperglycemia (high blood sugar), especially because it can lead to immediate and life-threatening situations. While high sugar levels over time can damage organs and increase the risk of complications, a sudden drop in glucose can impair brain function, cause unconsciousness, seizures, stroke and even be fatal if not treated promptly. This is where Continuous Glucose Monitoring (CGM) systems have become a game-changer. Although traditional glucometers are still widely used, especially by individuals who take insulin three to four times a day, CGMs offer a more convenient and accurate option. Many people on insulin therapy are advised to check their blood sugar at least three times daily — which isn’t always easy. CGMs solve this by offering real-time tracking and alerts via your smartphone. Worn on the arm or abdomen, CGMs can be programmed to alert you when your glucose levels begin to drop. For instance, if you set an alert at 90 mg/dL, the device might warn you at 88 mg/dL, giving you enough time to take action. This is especially beneficial for those with hypoglycemia unawareness, where symptoms are no longer felt even at dangerously low levels. It is also important to know that if someone has one episode of hypoglycemia, his risk of developing 2nd episode of hypo is higher and during this 2nd / 3rd hypo, the threshold for symptoms of recognition may go further low, this is known as Hypoglycemia-Associated Autonomic Failure (HAAF), can worsen with repeated episodes. Thus, we should avoid recurrent hypoglycemia episodes. To stay safe, especially for those new to diabetes care, never go more than 3.5 to 4 hours without eating. Even if you're not hungry, regular small meals are essential. Prioritize your health — and don’t hesitate to communicate your needs at work or school.
