###Human: Why do I get hives and swellings on eating mangoes? ###Assistant: Hello. You need to identify which part of the mango are you allergic to and avoid it. Is it the juice or for the peal? Also, any particular variety of mango needs to be identified like banganapalli, alphonso, etc. If recurring with all the variety of mangoes then try to avoid all mango varieties. Keep antihistamines tablet ready if you get an attack of the hive while having mangoes again. Also, the age-dependent development of allergy is difficult to explain. It might be you have become symptomatic after the period.
