Difficulty Breathing
This is where a person experiences shortness of breath or uneven breaths. The reaction might be so severe that it causes asthma-like symptoms such as wheezing and coughing.
Rash or Hives
This denotes the development of itchy, red, raised bumps on the skin. The rash can appear anywhere on the body and is one of the most common signs of an allergy.
Swelling
The person may notice swelling of the lips, face, tongue, or throat. This can impede breathing and is a sign that medical attention is needed immediately.
Tingling or Itching in the Mouth
This symptom showcases as a tingling or itching sensation inside the mouth, throat, or on the lips. The symptom may begin shortly after consuming the artificial flavoring.
Digestive Problems
This includes symptoms like stomach cramps, vomiting, diarrhea, or nausea. Digestive symptoms are common with food allergies and may occur quickly after ingesting artificial flavorings.
Anaphylaxis
In extreme cases, artificial flavoring allergies can lead to anaphylaxis, a severe and potentially life-threatening allergic reaction. Symptoms include difficulty breathing, sudden drop in blood pressure, rapid pulse, dizziness, or loss of consciousness.
