Can sugar cause migraines?

Yes, sugar is known to be a common trigger for migraines in some individuals. Consuming foods or drinks that are high in sugar can cause a rapid increase in blood sugar levels, which in turn can lead to a drop in blood sugar levels. This drop in blood sugar levels, also known as hypoglycemia, can trigger a migraine in some people. Additionally, some people may have an underlying sensitivity or intolerance to sugar, which can also trigger migraines. If you suspect that sugar may be a trigger for your migraines, it may be helpful to keep a food diary and track your symptoms to see if there is a correlation between your sugar intake and your migraines.
