Low blood sugar (diabetic hypoglycemia) affects people who have diabetes. It occurs when there's too much insulin and not enough sugar (glucose) in your blood. Several factors can cause diabetic hypoglycemia, including taking too much insulin or diabetes medication or skipping a meal.

Pay attention to early warning signs so you can treat low blood sugar promptly. Treatment involves short-term steps — such as taking glucose tablets — to raise your blood sugar into a normal range.

Left untreated, diabetic hypoglycemia can lead to seizures and loss of consciousness. This is considered a medical emergency. Tell family and friends what symptoms to look for and what to do in case you're not able to treat diabetic hypoglycemia yourself.
