What are food allergy symptoms and signs?

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, the gastrointestinal symptoms of food allergy 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 bloodstream. When they reach the skin, allergens can induce hives or eczema, and when they reach the airways, 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.

I seem to have trouble eating many types of fruits and vegetables together. For instance I made myself a 'green' drink, containing lettuce, cabbage, cucumber, a pear, also some ginger. I blended this together and drank it. Within half an hour I felt my face burning and my stomach was hurting and I felt very nauseous. Eventually about 2 hours later I did feel much better, however that evening I experienced extreme itching on my inner wrists, ankles and ribcage.

I had a heart attack. It started with a couple of days of off-and-on chest pain right in the center of chest. So I thought it was heartburn. I talked myself into thinking that for two days. On the third day I told myself if this kept up I had better go see a doctor. So I went all day with chest pains off and on. I was up watching TV at 3:00 am thinking my chest was hurting more than earlier in the day. So I tried to lie down when I felt this very bad pain in my chest, very tight feeling which then traveled up to my jaw. I also felt sweaty and sick. So I woke my husband and had him call 911. The paramedics were at my house very quickly, started an IV, and got my pain under control. I had 90 percent blockage and a stent was put in. My advice is, if you have chest pain go to hospital or call 911. I'm doing well now on maintenance medicine.
