What are the signs and symptoms of a yeast allergy?

According to HealthLine.com, the symptoms of a yeast allergy include abdominal swelling, dizziness and difficulty breathing, and joint pain. Fatigue after consuming a yeast product also signals an allergy. MD-Health.com indicates that diarrhea, constipation, indigestion and heartburn are early signs of a yeast allergy.

MD-Health states that yeast allergies are usually caused by consuming foods containing yeast, such as bread, cheese, beer or wine, tomato sauce, nuts, mushrooms and some condiments. MD-Health recommends consulting a doctor if symptoms occur often or repeatedly, as a yeast allergy can signal a weak immune system or diabetes. Additional symptoms including abnormal vaginal discharge, sinusitis, chronic cough and sore throat, nervousness and insomnia are signs of yeast overgrowth.
