Food Allergy, or Something Else?
Articles On Food Allergy
It’s pretty common to have a reaction to a certain food, but in most cases it’s an intolerance rather than a true allergy. Why does it matter? Although they may have similar symptoms, a food allergy can be more serious.
These clues can help you figure out if it is an allergy or intolerance. A doctor can help you know for sure.

Different Symptoms
When a food irritates your stomach or your body can't properly digest it, that’s an intolerance. You may have these symptoms:
A food allergy happens when your immune system mistakes something in food as harmful and attacks it. It can affect your whole body, not just your stomach. Symptoms may include:
- Rash, hives, or itchy skin
- Shortness of breath
- Chest pain
- Sudden drop in blood pressure, trouble swallowing or breathing -- this is life-threatening. Call 911 immediately.
Common Food Allergies and Intolerances
These triggers cause about 90% of food allergies:
The most common food intolerance is lactose intolerance. It happens when people can’t digest lactose, a sugar found in milk and dairy. Another kind of intolerance is being sensitive to sulfites or other food additives. Sulfites can trigger asthma attacks in some people.

What about a gluten allergy? While celiac disease -- a long-lasting digestive condition that’s triggered by eating gluten -- does involve the immune system, it doesn’t cause life-threatening symptoms.
Treatment for Food Allergy
Your doctor can find out if you have an allergy or intolerance. These things may help:
- Keep a diary of the foods you eat and the symptoms you have.
- Stop eating some foods to help figure out which one is causing symptoms.
- Have allergy tests done.
If you have a food allergy, you'll need to stop eating the food altogether. If you have a food intolerance, you’ll need to avoid or cut back on that food in your diet. For lactose intolerance, you can look for lactose-free milk or take a lactase enzyme supplement.
