For instance, eating simple sugar, such as white sugar, will raise the blood sugar quickly, and then insulin will overproduce, which is the rapid decrease in blood sugar.

Both types of hypoglycemia can potentially cause migraines and headaches. A headache that is dull and throbbing the temples is a type of migraine and headache. Many people also tend to feel nauseous with a migraine and headache that happens due to hypoglycemia.


It is known as a high blood sugar headache. This condition is caused by having a blood sugar that is too high in level.

Sugar can also be addictive, which may cause brain activity changes that are similar to addictive drugs. Consuming less sugar than usual can trigger the headache in the form of withdrawal symptoms. It can potentially happen on the initial day of the diet, such as removing sugar or cutting on candy from the diet.

According to a study, when a body gets excessive sucrose, the brain will produce a high amount of dopamine. The same study also noted the decrease in dopamine in rats when the sucrose withdrawal happened.
