I've noticed the brain "buzzing" (a general headache that makes me think my brain is swelling) and the partial light-headedness is worse after I eat, and depends on meal size.
I started tracking blood sugar levels to see if this was related and it seems to be, but at much lower levels than are considered "diabetic."
For example I range from below 100mg/dL before eating and as much as 120mg/dL after eating. However, within 10-15 minutes of eating I feel the head-effects starting up.
As a "control check" Sunday I drank a bunch of fruit juice (V8-fusion Light ACAI Berry) over the course of a few hours and got my blood sugar level up to 150mg/dL and the headache and overall head malaise were intolerable.
The brain buzz doesn't seem to be 100% linked to eating, as it's always worse in the afternoons, but maybe blood glucose levels and tiredness have the most to do with it.
What other levels spike after a meal that might be related?
Any thoughts?
