Pumpkin allergies are relatively rare, but may develop in children and adults. They are often linked to allergies to cucumber, melon, watermelon and zucchini, which are also members of the Cucurbitaceae family. You may also react to pollen, which contains similar proteins. Although there’s no cure, your doctor can prescribe medicines to relieve your symptoms.
Causes
If you’re allergic, your body overreacts to a protein found in pumpkins and other fruits. This stimulates production of Immunoglobulin E, an antibody and histamine. Some people may also develop an allergy to pumpkin seeds. Since similar proteins are found in ragweed pollen, symptoms are often worse during the pollen season in August and September. They are also more likely with raw, rather than cooked pumpkin.
Symptoms
Symptoms usually occur soon after eating pumpkins and are sometimes described as oral allergy syndrome. They include itching of the mouth, swelling of the lips and face, generalized itching, and shortness of breath. You may also have abdominal pain, nausea or vomiting. Serious reactions to fruit allergies are extremely rare. However, if you think you are having an anaphylactic reaction, which includes swelling of the throat, difficulty breathing and a weak, rapid pulse, call 911 immediately and go to the emergency room.
Tests and Diagnosis
If you suspect you have a pumpkin allergy, talk to your doctor and describe your symptoms. It can help to keep a food diary, noting any adverse reactions. You’ll usually be asked to take a skin test. This involves pricking your skin, and allowing a tiny amount of allergen below the surface. If you’re allergic, a rash will develop. This can also determine if you’re sensitive to other foods.
Treatment and Prevention
Your doctor can prescribe oral antihistamines to relieve symptoms such as itching and swelling. You can also buy these over the counter from drugstores. You can use hydrocortisone cream to treat a skin rash. If your allergy is related to pollen, allergy shots for hayfever may help. Of course the best way to avoid a reaction is to make sure you don’t eat any foods containing pumpkin. Check ingredient labels carefully, and ask detailed questions when you’re eating out. If you’re allergic to pumpkin seeds, remember they’re often used in breads and cakes, or sprinkled on salads, appetizers and main courses.
