In brief: Hypoglycemia

Low blood sugar may cause palpitations or fast heart rate, and causes a weak, shaky feeling.
Blood pressure may go up (due to heart working harder with stress) or down (due to overall weakness effect) or remain normal. If someone feels like sugar is low and unable to test right away, it's safe to eat/drink extra to bring sugar up than to wait and risk passing out, etc.
