Watermelon allergy is a type of food allergy that is caused by an immune system reaction to proteins found in watermelon. These proteins are called allergens. When someone with a watermelon allergy eats watermelon, their immune system mistakenly identifies the allergens as harmful and produces antibodies to fight them. These antibodies bind to the allergens and trigger a cascade of events that lead to allergy symptoms.

Skin prick test: This test involves pricking the skin with a needle and placing a small amount of watermelon extract on the prick. If you are allergic to watermelon, you will develop a raised, itchy bump at the test site.
Blood test: This test measures the level of antibodies in your blood that are specific to watermelon allergens. A high level of antibodies may indicate an allergy.
Treatment for Watermelon Allergy
There is no cure for watermelon allergy, but there are treatments that can help to manage the symptoms. These treatments include:
Avoiding watermelon: The most effective way to manage watermelon allergy is to avoid eating watermelon. This means reading food labels carefully and avoiding any foods that contain watermelon or watermelon extract.
Antihistamines: Antihistamines can help to relieve mild allergy symptoms, such as itching, sneezing, and runny nose.
Epinephrine: Epinephrine is a medication that is used to treat severe allergy symptoms, such as difficulty breathing and wheezing. Epinephrine is available in an auto-injector that is easy to use.
