Symptoms of Food Allergies
There is a wide range of symptoms that can occur with food allergies. Most reactions develop within 5-30 minutes
of eating it, although occasionally symptoms may not develop until 1-2 hours afterwards. Some individuals will be
very sensitive to foods and trace amounts will cause severe reactions, while others may be able to tolerate several bite
size pieces before having any reaction at all. It is important to note that foods are not the only cause of all of these
symptoms. For example, similar reactions can happen after a sting from a bee, exposure a latex product or a
cosmetic product, or taking a medication or supplement. It is thus important to tell your physician what you were
doing and what you may have ingested or been exposed to when you develop these symptoms so that he/she can have
a better idea of what may have happened.
Urticaria: One of the most common symptom of food allergies is a skin condition what called urticaria, commonly
called hives. Typically, hives look like a bunch of itchy raised blotchy red dots. The rash can show up just about
anywhere on the body.
Angioedema: This is a term used to denote swelling of certain parts of the body, such as the lips, tongue, throat, and
the area around the eyes. Swelling of the tongue and throat can be very dangerous and it can result in severe
difficulties breathing. Sometimes, the swelling can be inside the body. For example, the lining of the intestines can
swell, resulting in abdominal pain, and cramping.
Itching: This is also a common symptom of food allergies. Some people develop mild itching of the mouth or throat
after eating certain fresh fruits or vegetables, but no other symptoms. This is called the food-pollen syndrome.
However, itching of the palm of the hand, sole of the feet, eyes, ears or the whole body may signify a more serious
food allergy. Some women may develop vaginal itching after eating foods that are allergic to.

muscle spasms in the lungs. This may be more common in asthma patients. These symptoms can be very severe and
Abdominal problems: Vomiting and diarrhea are common symptoms, especially in infants and young children.
Abdominal pain can also happen after eating an allergic food. Women can develop abdominal cramps from spasms
of the uterus.

allergies. Some may also faint. These symptoms can be a sign of low blood pressure (called shock). This is a very
Metallic taste in the mouth: This is a rare phenomenon.
Impending Doom: A sensation that something very wrong and bad is going on.
It is important to note that food allergy is not the only medical condition that will cause these symptoms. Similar
reactions can happen with other allergies, such as insect, latex, and drug allergies. It is therefore important to tell
your physician what you were doing and what you may have ingested or been exposed to when you develop
symptoms so that he/she can have a better idea of what may have happened.
