Sugar is a vital component of the body’s chemistry. Too much or too little sugar can cause problems, including headaches.
This is because sugar has a direct effect on the brain and the nervous system.
It is vital for a person to maintain a proper level of sugar in their diet as it may prevent future headaches.
The Migraine Trust added: “Headaches produced from going without food are often quite severe and accompanied by mild nausea.
“There is also a similarity between some of the symptoms of missing a meal and the early warnings of a migraine attack such as yawning, pallor, sweating and craving for sweet things.”
