It could be and could not ,sugar headache and dizziness might be because of toxicity or dehydration event and while it might be an annoyance, it could also be the sign of something more dangerous like diabetes and other medical conditions .

If you get sugar headaches often, you might just be diabetic or pre-diabetic(meaning that you are at risk to have diabetes). The best way to find out if you are diabetic is to go and see your doctor and have them run some blood tests, but here are the typical symptoms of diabetes:
Excessive urination
Excessive thirst
Excessive hunger
>Diabetic condition characterized by having high blood sugar levels that can trigger a headache after eating something sweet. Eating sugary foods causes a sudden rise in blood sugar levels, which triggers the release of a hormone called insulin. Insulin increases the absorption of sugar into the cells, resulting in hypoglycemia or lowering of blood sugar levels. When large amounts of insulin are released in response to sugar intake, a "sugar crash" occurs and the brain does not receive enough sugar. This signals the body to send more blood flow to the brain. These changes lead to the expansion or dilation of blood vessels in the brain, which triggers a headache. The increase in blood flow to the brain can also cause the blood vessels to contract and dilate, resulting in increased blood pressure, also causing throbbing pains in the head.

>another cause might be migraine headaches ,where some food triggers a migraine attack ,watch what food is causing your headache and dizziness is it all sweets or just for example chocolate ,some fruits like straberries, bananas, meat, cheese may trigger it,or any specific sweet product containing additives .Migraine headaches may be accompanied by nausea and vomiting, lightheadedness and increased sensitivity to light,it is characterized by a throbbing sensation causing pain in the head. These may occur as a severe headache only on one side of one's head

other causes might be food allergy you may have glucose sensitivity or insuline resistance ,a metabolic disorder ,where after eating you may feel dizzy ,heartburn stomach upset and headache

other cause might be food intolerance for specific kind of food where you feel beside the symptoms you describe nausea and tiredness

GERD is another cause and might cause beside this heartburn ,cough,..

other cause is simply "dehydration "sugar can cause dehydration the major cause of headache and you may simply have headaches just because you aren't drinking enough water during the day, when you eat sugar your body has to dilute that sugar to keep it from harming your body. This means that water is pulled from all parts of your body to balance the large amount of sugar in your blood stream. While this water-pulling effect happens all over the body, it is your head that suffers the most and causes headache .

So there may be many causes depending on other symptoms associated with .
At the mean time try to eliminate the sugar that is causing this headache and write a dairy of what exact food are causing you headache and the quantity by which the effect of sugar cause a headache.
