Flour allergy: What are the signs?

Individuals with flour allergy might experience minor to severe symptoms. Some individuals end up with sensitivities to one or several substances present in wheat and some develop health issues after ingestion.

The allergic reactions to proteins and other compounds present in wheat can trigger minor to dangerous allergy symptoms. In some cases, using aspirin or engaging in exercise worsens the symptoms of flour allergy to a systemic or whole-body degree.



Once the body digests the food, diarrhea and intestinal cramps can occur.

Itchiness might arise from allergic reactions via direct skin exposure with flour or ingestion of foods containing flour.

Directly handling of white or whole-wheat flour can trigger eczema-like symptoms. It is characterized as itching and redness on the hands or other areas of contact with an elevated, bumpy rash called as hives. The individual might also have itchy mouth, lips, eyes, throat and tongue right after consuming foods that include wheat.

Breathing issues

During a reaction, the presence of histamine in the bloodstream can trigger an inflammatory response. Aside from the itchiness, the membranes in the mouth and nose become swollen which partly blocks the airways.

The allergy symptoms such as runny or stuffed nose might be like the flu or cold but linked to a flour allergy. If there is difficulty swallowing or breathing that occurs after consuming wheat-based foods, this link is likely.

Digestive issues

Flour allergy can trigger issues in the GI tract after an hour or more after consuming foods that contain wheat.

The timing might be affected by the amount ingested and other foods eaten. The sensation of nausea might arise first and followed by stomach pain or vomiting. Once the body digests the food, diarrhea and intestinal cramps can occur.

Risk for anaphylaxis

Anaphylaxis is a severe reaction that can occur if an individual has flour allergy. It develops rapidly than the digestive allergy symptoms, oftentimes moments after ingesting foods that include wheat.

Call for emergency assistance if anaphylaxis is suspected. The usual signs such as a rapid drop in the blood pressure can lead to confusion and weakness. Breathing issues might worsen which lowers the amount of oxygen that reaches the brain and heart. In addition, wheezing and an erratic pulse might arise before fainting and in extreme cases, death can occur.
