  • Frequent episodes of hypoglycemia can result in a situation generally known as hypoglycemia-associated autonomic failure (HAAF), the place the physique’s regular alert system to low blood sugar turns into much less delicate. Primarily, the physique and mind begin to adapt to decrease glucose ranges, diminishing the notion of hypoglycemic signs.
  • Tight blood sugar management, whereas essential for managing diabetes and stopping long-term issues, can paradoxically improve the danger of hypoglycemia unawareness. It’s because aiming for decrease blood sugar targets could result in extra frequent episodes of hypoglycemia, thereby growing the probability of HAAF.
  • The usage of steady glucose monitoring (CGM) programs makes tight diabetes management simpler by offering real-time suggestions on blood glucose ranges. Whereas CGMs can alert customers to impending lows, the general threat of hypoglycemia unawareness should still be influenced by the aggressive pursuit of tight glucose targets.

Not everybody who takes insulin will expertise hypoglycemia unawareness, however the probability will increase with the size of time somebody has had diabetes.
