Health Tip: Recognize the Signs of Food Allergy

(HealthDay News) -- Food allergy reactions range from mild to life-threatening, depending on the person.

The Nemours Foundation says common warning signs of a milder allergic reaction to food may include:

• A tight feeling in the throat, or a hoarse voice.
• Coughing and wheezing.
• Nausea, vomiting or stomach pain.
• Diarrhea.
• Hives or skin rash.
• A tingling sensation on the lips or tongue.
• Runny nose.

In more serious cases, food allergy may cause a severe reaction called anaphylaxis, which may cause a person's breathing pathways to narrow, blood pressure to drop, and tongue to swell. This should be treated as a life-threatening medical emergency.
