From Indiana, USA:
What happens when your blood sugar gets too low?
Too low a level of glucose (sugar) in the blood (generally below 60 mg/dl) can occur when a person with diabetes has injected too much insulin, eaten too little food, or has exercised without extra food. A person with hypoglycemia may feel dizzy, nervous, shaky, weak, or sweaty, and have a headache, blurred vision, lightheaded sensation, hunger and find it very difficult to concentrate. This is a consequence of the release of the counterregulatory hormones (such as epinephrine and norepinephrine, growth hormone and cortisol) which are produced as a response of the body towards increasingly lower blood sugar levels. In fact, glucose is vital for our brain cells to survive and this is one of the reason why we have plenty of counterregulatory hormones (i.e. to keep our blood sugar from falling below critical levels) while there is only one hypoglycemic hormone, that is, insulin.
Taking small amounts of sugar, sweet juice, or food with sugar will usually help the person feel better within 10-15 minutes.
