Why do I get a headache after I eat sugar?

Various causes of a headache after eating sugar result in multiple forms of pain levels. Some of the major causes of headaches due to sugar are :

Hypoglycemia 

Hypoglycemia is characterized by insufficient blood sugar levels. When your blood sugar levels fall below 70 mg/dL, you experience hypoglycemia. Skipping a meal and having sugar instead or going for a long time without eating may trigger hypoglycemia. Production of excessive insulin by the body after having sugar is the cause of headaches. 

Hyperglycemia

Consumption of sugar also triggers hyperglycemia which may result in headaches. Hyperglycemia is brought on by having a very high blood sugar level. When insulin cannot effectively break down glucose in your body, this occurs. Your blood sugar can exceed 180–200 mg/dL. A headache could be an early sign that you have very high blood sugar.

Sugar hangover

Your blood glucose levels could change quickly if you consume a lot of sugar in a short period and then do not consume any. That may result in a sugar hangover. In moderation, sugar shouldn’t give someone a headache, but too much or too little sugar can cause a sudden change in blood sugar levels.

Sugar withdrawal

Sugar has the potential to become addictive. This brings similar changes in brain activity as when someone becomes a drug addict.

A “sugar withdrawal” headache can also be brought on by eating less sugar than usual. This might occur, for instance, on the first day of a new diet or after reducing your intake of sweet candies or sugary beverages.
