These conditions can often be confused, but there are a few differences between a food allergy and a sensitivity that you should be aware of. Here are some indications to help differentiate between the two conditions:
Food Allergy Symptoms
- Appear immediately
- Involve an immune system response
- Small amounts of a food can trigger a big reaction
- A reaction occurs every time a specific food is eaten
- The situation may become life-threatening if the response is severe.
Food allergies can present very serious, sometimes life-threatening symptoms. The following symptoms can turn serious very quickly if left unattended,
- A rash, or hives may appear that causes the area to itch
- Shortness of breath due to swelling of the bronchial tissue in the lungs
- Difficulty swallowing caused by a swollen larynx
- A swollen tongue
- Chest pain accompanied by a change in blood pressure
When and if an individual in Ottawa begins to feel chest pain, difficulty in breathing and/or swallowing, call 911 immediately.
Food Intolerance Symptoms
- Appear gradually
- Involve a digestive system response, but can also involve other body systems
- Takes place when large servings are eaten
- The reaction will never be life-threatening
For people with a food sensitivity or intolerance, the body is unable to process or digest the food correctly. The following symptoms may occur:
- Heartburn
- Cramps, bloating, or gas
- Headaches
- Nervousness, or Irritability
Shared Symptoms of both Intolerance and Allergy May Include:
- Abdominal discomfort
- Vomiting
- Diarrhoea
- Nausea
