Warning Signs of Food Allergy
If you have a food allergy, your immune system mistakenly regards a particular food as harmful and begins producing antibodies to that food. Each time you eat that food, your immune system releases various chemicals to protect your body. These chemicals produce symptoms that can affect your airways, skin, or intestinal tract. Symptoms of food allergy can include:
• skin reactions such as hives or rashes
• nasal congestion
• nausea, diarrhea, or gas
• shortness of breath, or asthma attacks in people who have asthma
If the reaction is severe, you may experience life-threatening symptoms within minutes of eating. A severe allergic reaction can rapidly cause difficulty breathing, lowered blood pressure, and loss of consciousness (see “Anaphylactic Shock,” post). If you or a person you are with has these symptoms, seek emergency medical help immediately.
