Why my head hurts when I eat sugar - here's the answer

To finish clarifying this issue, in we have prepared this article in which we answer your question about “why does my head hurt when I eat sugar?”.

Why Eating Sugar Gives a Headache

If you have ever wondered why my head hurts when I eat chocolate, ice cream or sweet in general you will be interested to know that, although a few decades ago the relationship was not very clear, it is currently known that there is a headache for having high sugar or hyperglycemia, in fact depending on the situation there may be a slight pain, headaches or even migraines, which last for hours or a few days, and there may also be dizziness.

What exactly happens is that when eating sugar, which is a simple carbohydrate, the blood glucose level rises, but if the body cannot perform well the necessary processes to use this glucose, it stays in excess in the blood producing a hyperglycemia or high blood glucose level and various derived problems, among them dizziness and headache.

Specifically, the headache occurs because excess glucose in the blood causes the erythrocytes or red blood cells to release some of the water they contain to compensate for the situation and dilute the hypertonic plasma, that is, loaded with glucose, and help return to the normal state. This results in dehydration of the cells, poor circulation and lack of oxygen in the cells. It is especially noticeable in the head because the cranial arteries are especially sensitive to blood saturation.

Therefore, this problem has several basic causes, so it can occur in people who have:

  • Diabetes.
  • Insulin resistance.
  • With other problems in the pancreas and liver.
  • A regular diet with few sugars.
  • Someone who eats a lot of sugars only once, without having to have any of the above situations.

How to Remove the Headache from Eating Sugar

If you are one of the people who have a headache after eating sugar, the first thing you need is to know what the exact cause is in your case. Thus, the first thing will be that the doctor tells you if you are diabetic or insulin resistant or not and, if you are, you will need to follow the treatment indicated and stop eating sweets and sugar as you did until now, reducing it to the guidelines given by the specialist. It is important to make it clear that people who suffer from these diseases should not stop eating sugar or carbohydrates completely, as it is a common mistake and that only leads to hypoglycemia and other problems, but they have to learn to manage blood glucose and insulin levels.

On the other hand, it will be different if the headache is due to eating excess sugars or, if it is because you usually eat little or only complex carbohydrates and one day you eat more amount or simple carbohydrates, which are those that convert more quickly into blood glucose and therefore accumulate more easily. In these cases what should be done is to be aware that this happens to you, especially if it has happened to you several times, and avoid eating a lot of food with a high level of simple carbohydrates at once.

If you thought you had to give up sugar because it causes a headache, remember that it is not about quitting altogether. You should not stop eating sugars and other carbohydrates, but you will have to reduce the simple ones as much as possible and eat basically the complex ones. Therefore, forget about eating industrial pastries, cakes, cakes, soft drinks and other foods with lots of simple carbohydrates.

Anyway, the best way to do it is with the help of an endocrine, who is the specialist who will know if your hormone production is correct, there is a problem or if you simply need more than one type of nutrient or another and can help you have the most appropriate diet for you.

The above implies changing habits, so it is a long-term solution and not to solve the problem or discomfort at the moment, that is, in the middle of the crisis.

In such a case, if it has just happened to you and you want to improve you will have to think again about the cause. If you are diabetic use insulin in the necessary dose, but if it has been due to excess and you do not have problems with insulin production and assimilation, then it is best to help your body burn the excess accumulated glucose. Even if your head hurts, do some gentle exercise, such as walking. If the pains become strong headaches or migraines, in such a case it is best to rest in low light or without and try to sleep.
