When you experience stress, your body releases cortisol and adrenaline - hormones that signal the liver to release stored glucose and reduce insulin sensitivity. This is the fight-or-flight response:
Acute stress (an exam, argument, or deadline) typically causes a sharp but temporary glucose rise lasting 30-90 minutes as cortisol clears.
Chronic stress (ongoing work pressure, relationship difficulties) sustains elevated cortisol over time - contributing to insulin resistance and gradually raising HbA1c by an estimated 0.1-0.3% per point on the severity scale.
Note: Individual stress responses vary considerably. Some people find their glucose drops under stress (parasympathetic dominant), while others see larger rises.
The cortisol-glucose connection is one of the most underestimated factors in diabetes management. The FOD Starter guide (Chapter 12) explores the science of stress and blood sugar, plus practical strategies for managing this invisible variable.
