Answer 2

What are the symptoms of food allergy?

The complex process of digestion affects the timing, location, and particular symptoms of an allergic reaction to food. All of the symptoms of food allergy occur within a few minutes to an hour of eating. A food allergy can initially be experienced as an itching in the mouth and difficulty swallowing and breathing. Then, during digestion of the food in the stomach and intestines, symptoms such as nausea, vomiting, diarrhea, and abdominal pain can start. Incidentally, gastrointestinal symptoms are those that are most often confused with the symptoms of different types of food intolerance.

As mentioned previously, the allergens are absorbed and enter the blood stream. When they reach the skin, allergens can induce hives or eczema, and when they reach the lungs, they can cause asthma. As the allergens travel through the blood vessels, they can cause lightheadedness, weakness, and anaphylaxis, which is a sudden drop in blood pressure. Anaphylactic reactions are severe even when they start off with mild symptoms, such as a tingling in the mouth and throat or discomfort in the abdomen. They can be fatal if not treated quickly.

Food allergy or food intolerance affects nearly everyone at some point. When people have an unpleasant reaction to something they ate, they often think that they have an allergy to the food. In fact, one out of three people say that some member of their family has an allergy to food that has necessitated a change in their diet. Actually, however, only about 1% of adults and 3% of children have clinically proven allergic reactions to food.

This difference between the prevalence of clinically proven food allergy and the public's perception of the problem is due primarily to misinterpreting food intolerance as food allergy. Food allergy is an abnormal response to food that is triggered by a specific reaction in the immune system and expressed by certain, often characteristic, symptoms. Food intolerance also is an abnormal response to food, and its symptoms can resemble those of food allergy. Food intolerance, however, is far more prevalent, occurs in a variety of diseases, and is triggered by several different mechanisms that are distinct from the immunological reaction responsible for food allergy.

People who have food allergies must identify and prevent them because, although usually mild and not severe, these reactions can cause devastating illness and, in rare instances, be fatal.

Patients present with skin symptoms, throat tightness, shortness of breath, lightheadedness and/or stomach symptoms. The symptoms usually develop within half an hour of ingesting the allergen.
Rarely, food allergy can lead to anaphylactic shock: hypotension (low blood pressure) and loss of consciousness. This is a medical emergency. Allergens commonly associated with this type of reaction are peanuts, nuts, milk, egg and seafoods. Latex products can induce similar reactions.
Food allergy is thought to develop more easily in patients with the atopic syndrome, a very common combination of diseases: allergic rhinitis and conjunctivitis, eczema and asthma. The syndrome has a strong inherited component; a family history of these diseases can be indicative of the atopic syndrome.

Answer 4

I get a weird feeling in my throat if I eat some foods I'm allergic to. Hives, rash, fever, digestive issues, swelling of the throat and face are also some symptoms, but there are many and they can be completely specific to you. I get hard painful bumps on my fingertips if I take certain medications. It just depends on you.

Answer 5

It is easy to confuse a food intolerance with an allergy because both conditions can have similar symptoms. If you have a food intolerance you can usually eat a small amount of the offending food without it causing a problem. However, those who suffer severely from food allergies can experience symptoms after the smallest amount of food comes into contact with their lips or even their hands if touched. Symptoms typically occur, within minutes to 2 hours after the person has eaten the food to which they are allergic.

Symptoms of food intolerances can include:
-Diarrhea and flatulence.
-Stomach pain.
-Nausea and vomiting.
-Fatigue.
-Migraines.
-Sleeplessness.

Symptoms of a food allergy may include:
-Swelling of the lips, face, tongue or throat - this may lead to suffocation .
-A tingling/itchy sensation in the mouth and lips.
-Stomach cramps.
-Feeling of weakness - caused by a drop in blood pressure.
-Vomiting and diarrhea.
-Blotchy, itchy skin rashes.
-Headaches.

It is important that if you experience any kind of allergic reaction after eating (especially peanuts, nuts and seeds) that you contact your doctor for further advice and avoid that food until then. Even if the symptoms are mild this time, like a tingling lip, the next time you eat that food you might suffer a severe allergic reaction (anaphylaxis).

I hope this helps you!
