Reactive hypoglycemi: Some people develop reactive hypoglycemia after eating sugar products as their body secretes too much insulin for them when their blood sugar rises and instead of bringing their blood sugar to normal, the sugar drops too low causing fatigue and at times weakness. A 4-6 hr glucose tolerance test Is diagnostic.
