What is the relationship between fluctuations in my blood sugar and hypoglycemia and occurrence of a headache?
As one’s blood sugar drops too rapidly, it can trigger a headache of a migraine type. In addition, a person with an abnormal blood sugar metabolism can trigger a headache by missing even a single meal. So it is better to eat regularly, at the same time in the day, and regulate medications around meal times as well. Headaches that occur after sleeping longer than usual or headaches that occur during the night or upon awakening may reflect hypoglycemia, although many other explanations are possible.
