Jalapeno peppers come in red and green varieties. Capsaicin, the structure found in jalapenos that make them spicy, can irritate the mucus membranes in your mouth, nose and eyes as well as irritate your skin. Many people choose to wear gloves to help avoid skin irritation while cooking with jalapenos. Most allergic reactions to jalapenos come from eating them uncooked, although it is possible to experience an allergic reaction to cooked jalapenos as well.
Loose stools and diarrhea can be a sign of an allergy to jalapenos.
If you begin to feel nauseous after eating a recipe containing jalapenos, you may be having an allergic reaction to them.
A jalapeno allergy may trigger migraines or headaches after consumption.
A more severe symptom of a jalapeno allergy is wheezing and difficulty breathing. Medical treatment may be necessary.
A scratchy throat can be a sign of an allergy to jalapenos.
If your face swells after consuming jalapenos, it may be a sign of anaphylaxis (a severe allergic reaction). Seek medical attention.
