FAQ
Frequently asked questions
What are the symptoms of a potato allergy?
Symptoms can vary but may include hives, itching, swelling, digestive issues like nausea or vomiting, and in severe cases, difficulty breathing. Onset can be immediate or delayed.
Can children have a potato allergy?
Yes, children can develop allergies to potatoes, just as they can to other foods. Symptoms in infants and young children may include fussiness, rash, or digestive upset after eating potatoes.
How is a potato allergy different from a sensitivity?
An allergy involves an immune system response, specifically IgE antibodies, which can cause rapid and potentially severe reactions. A sensitivity is typically a digestive issue and does not involve the immune system in the same way.
If I have a positive test, does it mean I must avoid potatoes forever?
A positive test indicates sensitization, but it doesn't always mean you will have a reaction every time you eat potatoes. Your doctor will interpret these results along with your symptoms and medical history to guide dietary recommendations.
