Yeast intolerance is a condition that indicates the body's decreased ability to digest yeast, often causing gastrointestinal discomfort. This is different from a yeast allergy, which triggers an immune response and can result in more severe symptoms. People with yeast intolerance usually experience digestive problems after eating yeast or foods that contain yeast.

Yeast intolerance involves the digestive system’s inability to properly process yeast, resulting in discomfort and various symptoms. This is a non-immune response, unlike a yeast allergy, which is an immune reaction to proteins in yeast, potentially causing severe symptoms like hives, swelling, or anaphylaxis. Yeast intolerance generally leads to milder, primarily digestive-focused symptoms and does not involve the immune system.
If you consistently experience digestive discomfort such as bloating, abdominal pain, or diarrhea after consuming yeast or yeast-containing products, it may be wise to consider a test for yeast intolerance. This is particularly important if these symptoms disrupt your daily activities or if the specific cause of your discomfort is unclear, as it could be indicative of other dietary sensitivities or health issues.

Do you have hypersensitivity to certain foods? Symptoms of food intolerance, unlike instant allergic reactions, can occur hours to days later, making it difficult to connect symptoms with the foods you’ve eaten. GetTested’s Food Intolerance Test analyses IgG4 antibodies for 80 different foods commonly involved in hypersensitivity reactions.
For those concerned about coeliac disease, we offer a simple Coeliac/Gluten Intolerance Test, which is distinct from the gluten sensitivity measured in this test. Additionally, if you suspect lactose intolerance—specifically sensitivity to milk sugar—our Lactose Intolerance Test, an exhalation test that measures hydrogen and methane, may be appropriate.
