After i drink something sweet i get a headache but not after i eay something sweet could this be diabetes?i have no other symptoms of diabetes

Sweet foods: The symptoms of diabetes are typically fatigue, excessive urination and thirst, and many others, perhaps including headache, but not a headache when drinking sweets. If you have diabetes, your sugar is high all the time, not just after drinking a soda. See your doctor and get your sugar checked, if you wish, but this does not sound like diabetes.
