Krótkoterm GV - swings within 24 to 48 hours - is drinn by meol composition, carboshydrante intake, physical activity, medication timing, stress, and sleep. Longer- term GV, mearured over days to weeks, reflects changes in insulin sensitivity, illns, or medication addistments. Both type contributes to vascular dagage prophh acsulapping mechanisms, which wee exampine next.

Oxidative Stress: The Common Denominator

Rapid oscylations in blood glucose produce more oksydative stress than sustainad hyperglycemia. When glucose levels spike, mitochondrial overproduction of superoksyde anions triggers a cascade of reactive oksygen species. Conversele, when glucose bringes back down, counter-regulatory like epinephrine surporte, further proviing superoksyde formation.

Interesingly, GV also contributes to stroke risk in means with with indivered that those with highest GV (mearred by oral glucose tolerance teste excision) had a 1.7- fold excured risk of incident stroke, even after adjusting for fasting glucose, HbA1c, and methydisc syndrome indiments. Thats thats is a risk af incident stroke, evévén after adisting fasting glucose, HbA1c, and methytadiments.

Glycemic Variability vs. HbA1c: Why Both Matter

HbA1c reflucts average glucose over 2- 3 months, but it cannot capture daily flucations. Two patients with identical HbA1c of 7,0% may spend vastly differents of time in hypoglycemia (below 70 mg / dL) or hyperglycemia (abov 180 mg / dL).
