Mushroom allergy is an immune system response to the proteins in mushrooms. The symptoms can range from mild to severe and can be life-threatening in some cases. Mild symptoms may include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. More severe symptoms can indicate an anaphylactic reaction, a life-threatening allergic response that requires immediate medical attention. These may include difficulty breathing, wheezing, dizziness, rapid heartbeat, severe abdominal pain, and a sudden drop in blood pressure. The overall extent of mushroom allergy is not known, but it is believed to be rare.

What You'll Learn
Mushroom allergy symptoms
Mild symptoms of a mushroom allergy may include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. These symptoms can be treated with over-the-counter antihistamines, vitamin C, aloe vera, and epinephrine.
More severe symptoms can indicate an anaphylactic reaction, which is life-threatening and requires immediate medical attention. These symptoms include difficulty breathing, wheezing, dizziness, rapid heartbeat, severe abdominal pain, coughing, vomiting, diarrhea, and a sudden drop in blood pressure. In such cases, an injection of epinephrine (adrenaline) is administered to reverse the effects of anaphylaxis.
It is important to note that the overall extent of mushroom allergies is not precisely known. Some studies suggest that it may be very slight (1%) in certain populations, while others indicate that it could be as prevalent as pollen and mould allergies (10-30%) in allergic populations.

Mushroom allergy diagnosis
Mushroom allergy is an immune system response to the proteins in mushrooms. The symptoms can range from mild to severe and can sometimes be life-threatening. The symptoms of a mushroom allergy include hives, swelling, coughing, wheezing, vomiting, and diarrhoea. In more severe cases, an allergic reaction to mushrooms can lead to anaphylaxis, which is characterised by a rapid drop in blood pressure, difficulty breathing, and loss of consciousness.
The overall extent of mushroom allergy is not known. It may be very slight (1%) from eating mushrooms, but it could also be as prevalent as pollen and mould allergies (10-30% of an allergic population).
Blood tests are another method used to diagnose mushroom allergies. These tests measure the amount of immunoglobulin E (IgE) antibodies in the blood. High levels of IgE antibodies suggest that the individual is allergic to mushrooms.
It is important to consult with a medical professional if you suspect you have a mushroom allergy. A physician will be able to perform a physical examination, review your medical history, and conduct the appropriate tests to determine the specific allergen causing the allergy.

Mushroom allergy treatment
Mushroom allergy symptoms can range from mild to severe and can even be life-threatening in some cases. Mild symptoms may include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. More severe symptoms can include coughing, wheezing, vomiting, diarrhea, swelling of the throat, tongue, mouth, or lips, breathing difficulties, and anaphylaxis.
The choice of treatment for a mushroom allergy typically depends on the severity of the allergy and the patient's overall health condition. Medications are often the first line of treatment. Over-the-counter (OTC) antihistamines can help alleviate mild symptoms. For severe symptoms, doctors may prescribe corticosteroids to reduce inflammation. In emergency cases, such as anaphylaxis, epinephrine (also known as adrenaline) is administered.
Allergy shots, also known as allergen immunotherapy, involve injecting small doses of the allergen into the body to help build up immunity. Over time, this can reduce the severity of allergic reactions. This treatment method is typically recommended for patients with severe allergies or those who don't respond well to medications. Sublingual immunotherapy is a newer treatment method that involves placing a tablet containing the allergen under the tongue.
The most effective way to prevent a mushroom allergy is to avoid exposure to mushrooms. This includes not only avoiding eating mushrooms but also avoiding areas where mushrooms are grown or processed. It is also important to read food labels carefully, as many processed foods may contain mushroom extracts or other fungal ingredients.

Mushroom allergy prevalence
The overall extent of mushroom allergy is unknown. It may be very slight (1%) from consuming mushrooms, but it could also be as prevalent as pollen and mould allergies (10-30% of an allergic population).
Mushrooms are widely consumed as a nutritious food worldwide. However, some individuals may experience an allergic reaction after consuming them. Mushroom allergy is an immune system response to the proteins in mushrooms. The symptoms can range from mild to severe and can sometimes be life-threatening.
The allergic reaction is caused either by eating mushrooms or inhaling their spores. Different species of mushrooms, from shiitake to button mushrooms, can cause various symptoms. Consuming mushrooms can trigger skin irritation, hives, rashes, and itching. Some people have also reported swelling of the lips, mouth, and throat due to mushrooms. Swelling of the throat can cause breathing difficulties. A severe allergic reaction or anaphylaxis can occur, which sets a chain reaction of symptoms, including a rapid drop in blood pressure, shortness of breath, and fainting, requiring immediate medical attention.
Inhalation of mushroom spores can inflame the upper respiratory tract and cause a runny nose and watery eyes. Wheezing, coughing, vomiting, and diarrhea may also occur.
The most effective treatment for mushroom allergy is avoidance. Individuals with a mushroom allergy should avoid all types of mushrooms and carefully read food labels and ingredient information in restaurants. Antihistamines can help relieve mild allergy symptoms but are ineffective in treating anaphylaxis.

Mushroom allergy and fungus
Mushrooms are widely consumed as a nutritious food worldwide. However, some individuals may experience an allergic reaction after consuming, inhaling, or touching them. The overall extent of mushroom allergies is unknown, but it is thought to be rare. It may be as low as 1% of the population, but it could be as high as 10-30%, similar to pollen and mould allergies.
A mushroom allergy is an immune system response to the proteins in mushrooms. The symptoms can range from mild to severe and can be life-threatening in some cases. Mild symptoms may include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. More severe symptoms can indicate anaphylaxis, a life-threatening allergic response that requires immediate medical attention. These may include difficulty breathing, wheezing, dizziness, rapid heartbeat, severe abdominal pain, coughing, vomiting, and a sudden drop in blood pressure.
If you suspect you have a mushroom allergy, you should consult a doctor or allergist. Skin prick tests and blood tests are the most common methods of diagnosing allergies. During a skin prick test, a small amount of mushroom extract is pricked or scratched into the skin. If a raised bump appears within 20 minutes, it indicates an allergy. Blood tests measure the amount of Immunoglobulin E (IgE) antibodies in the blood, with high levels indicating an allergy.
The only way to treat a mushroom allergy is to avoid consuming mushrooms and other fungus-related foods, such as mycoprotein and fermented foods. Medications are often the first line of treatment for mild symptoms, with over-the-counter antihistamines and vitamin C helping to alleviate itching and inflammation. For severe symptoms, doctors may prescribe corticosteroids to reduce inflammation. In emergency cases of anaphylaxis, epinephrine (adrenaline) is administered. Allergy shots are also an option, helping to desensitise the immune system to mushrooms over time.

Frequently asked questions
A mushroom allergy occurs when the immune system doesn't recognize the proteins found in mushrooms as safe and attacks them with immunoglobulin E (IgE) antibodies, which trigger mast cells to create histamine. This can cause an allergic reaction, with symptoms ranging from mild to severe and life-threatening.
Mild symptoms of a mushroom allergy may include a rash, itching, hives, sneezing, nasal congestion, and minor digestive issues such as stomach discomfort. More severe symptoms can indicate an anaphylactic reaction, a life-threatening allergic response that requires immediate medical attention. These may include difficulty breathing, wheezing, dizziness, rapid heartbeat, severe abdominal pain, and a sudden drop in blood pressure.
A mushroom allergy can be diagnosed through skin prick tests and blood tests. Skin prick tests involve exposing the skin to small amounts of mushroom allergens to see if an allergic reaction occurs. Blood tests measure the amount of IgE antibodies in the blood, with high levels indicating an allergy.
