Can I suffer from headache by eating wheat?

If the individual develops a headache after eating wheat or products that contain wheat, it is most likely connected to nasal congestion from wheat allergy. An individual who is allergic to wheat will have an elevated level of histamine in the sinus cavity which can lead to irritation that leads to swelling and inflammation. Take note that the swelling of the sinuses will add pressure on various regions of the head, resulting to headaches.

In case the individual develops other symptoms after eating wheat and foods that contain wheat, it is best to consult a doctor for further assessment. The headaches might not be connected to wheat and can indicate a symptom of a serious health condition.

What is wheat allergy?

Wheat allergy basically affects individuals below three years old but can affect any individual at any age. Always bear in mind that wheat allergy develops once the immune system mistakenly identifies the proteins present in wheat as a threat to the body. As a result, the immune system establishes a defense system that attacks the proteins with antibodies and histamine. These chemicals are responsible for triggering the common symptoms during an allergic reaction.

One of the usual symptoms of wheat allergy is congestion of the nasal passages.

One of the usual symptoms of wheat allergy is congestion of the nasal passages. The histamine that was generated in the sinuses can trigger the swelling of the nasal passages, thus disrupting the capability to drain out the mucus or allow the individual to breathe via the nose. Excessive amount of mucus ends up trapped in the sinuses and presses on the eyes, cheek bones, upper teeth, inner ear and forehead. Mild to severe pain can occur within minutes of eating wheat if the individual is sensitive to it.


An effective way to prevent headaches from wheat is to eliminate wheat from the diet. At the present, all pre-packed foods must clearly reveal on the label the presence of wheat in the product. Take note that some ingredients are not quite apparent such as in spelt, cereal extract and couscous.


You can manage sinus headaches caused by wheat allergy by providing the individual with antihistamines, pain relievers and decongestants. Antihistamines can help minimize the amount of histamine present in the sinuses by limiting the mast cells from generating the hormone. Decongestants are given in order to minimize the inflammation in the sinuses by slowing down the flow of blood into the sinuses. Pain relievers are used in order to alleviate the sinus pressure pain or headaches. You have to consult a doctor regarding the appropriate medications that are suitable for the condition of the individual.

In case the individual develops swelling in the forehead, area surrounding the eyes or in the throat, you have to consult a doctor right away since this can indicate a serious condition. Take note that a severe allergic reaction to wheat can result to death. The usual symptoms include anxiety, hives, difficulty breathing and elevated heart rate. You have to call for emergency assistance if these symptoms occur. If you want to learn how to manage a severe allergic reaction, read here.
