Correct. When blood sugar drops too low, the body responds by releasing adrenaline, a hormone that signals an Emergency Situation [Fight or Flight System].
This surge of adrenaline is what causes many of the symptoms associated with hypoglycemia, such as a racing heart, tremors, sweating, anxiety, and nervousness. (Think of riding a big scary roller coaster, or seeing a bear in person!)
These symptoms serve as an alert to prompt you to take action and raise your blood sugar levels, essentially acting as the body's built-in alarm system. Your body will make a small amount of sugar due to adrenaline, but not enough to rely on! You need to act FAST!
