Food allergy is caused by proteins contained in the food we consume. In most cases, the allergic reactions start showing up while consuming food or immediately after consuming food. In other instances, it may show up a few hours after eating the food. In people who are highly sensitive to these proteins, the body will react allergically, even on touching the food item. Therefore, it is important to know food allergy symptoms and be able to identify them. Given below is a list of symptoms of food allergy noticed in most people.
* Tingling sensation in the mouth, lips, throat
This can start immediately or within a few minutes.
* Itching or swelling of the lips, mouth, eyes and the rest of the face
These food allergy symptoms can start immediately or within a few minutes of eating. The limbs can also swell as a result of the allergic reaction.
* Swollen tongue and difficulty in swallowing (angioedema)
This is due to swollen tongue, which is an allergy caused by the proteins in the food.
* Stomach cramps and abdominal pain
This is due to an allergic reaction in the stomach
* Nausea and vomiting
This is an allergic reaction to some proteins during the digestion of food.
* Difficulty breathing and wheezing
An allergic reaction will cause the swelling of the breathing tract, which makes breathing difficult.
* Nose block or runny nose
This is a common allergic symptom and occurs due to an allergic reaction.
This is due to the gastrointestinal distress caused by the allergic reaction to certain proteins.
* Low or irregular blood pressure
This is caused as the heart is affected by dilation or constriction of the blood vessels as a result of the allergic reaction to proteins in the food consumed.
* Dizziness or fainting
This is a severe form of food allergy.
* Rash or hives on the skin
Reddish or pinkish bumps appear on the skin, which will be highly itchy. Otherwise, several patches, pink or red in color will appear on the skin.
These are the general symptoms and their severity will depend on the person’s ability to tolerate the allergy. However, sometimes the body will react severely to the presence of some proteins. This kind of reaction is called Anaphylaxis or anaphylactic shock. This occurs almost all of a sudden. The person will lose consciousness and may even die due to complications caused by allergy.
Several symptoms occur almost at the same time, which does not allow the body time to adjust and accommodate. The person’s heartbeat becomes irregular due to disturbances in the blood vessels surrounding the heart. The person suffers from diarrhea and vomiting due to the contraction of the digestive tract. The airway also becomes constricted causing breathing difficulties. Rashes and hives appear on the skin accompanied by swelling and the person will feel itchy.
Anaphylaxis can occur either immediately or within a few hours of consumption of food. The person must be administered epinephrine to help stabilize the body and he must be immediately hospitalized. Mild food allergy symptoms do not necessitate a hospitalization and the person is usually able to tolerate the condition. However long terms effects should be considered and the person must be examined for allergic reactions.
