When blood sugar rises fast and crashes hard, the body reads that as stress.
And one of the hormones that steps in to help manage that stress response?
Cortisol.
This is one reason blood sugar instability can show up in people dealing with:
• fatigue
• anxiety
• hormone imbalance
• thyroid symptoms
• hair shedding
And blood sugar stress is not just about sweets.
It can come from:
• not eating enough protein
• eating carbs without balance
• skipping meals
• too much caffeine
• chronic stress
• poor sleep
• inflammation affecting metabolic health
There is also another layer: glycation.
That is what happens when excess sugar binds to proteins in the body, creating damage and more inflammatory stress over time.
So yes, blood sugar swings can be dietary.
And they can also be part of hidden inflammation.
