Allergies or reflux?: It could be allergies, but with stomach issues it is very likely "laryngopharyngeal reflux" is playing a role. Throat clearing, feeling of mucous or tickle in the throat that won't go away, nighttime cough, sore throat, bad taste in mouth, hoarse, wet burps... Sound familiar? If so it's likely reflux.

Can you tell if nausea after a food is a food allergy?

Skin testing: Skin testing can reveal a food allergy, but will be negative if the nausea represents an intolerance. If you're able to identify the food that is causing the nausea, there is no need for skin testing, because there is no specific treatment for specific food allergies. Whether the nausea represents a true allergy or an intolerance, the treatment is the same - just avoid the food. ...Read more
