Hypoglycemia is a term meaning low blood sugar. It can be a symptom of various diseases. Hypoglycemia can be easily misdiagnosed. Most of us have low blood sugar at certain times, for example, when we awake in the morning. However, a nutritious breakfast supplies the energy needed to bring the blood sugar level back to normal. People who have hypoglycemia may produce too much insulin in response to high blood glucose. This results in low blood sugar levels. As a result, people with hypoglycemia may have to modify their intake of sugars. A physician or registered dietitian will be able to develop a hypoglycemic diet that is right for you.
