Itchy throat after eating mangoes may be caused by allergic reaction to food caused by mangoes. In the early stage, itchy throat may lead to congestion, edema and even choking as the condition develops. Therefore, it is recommended to seek medical attention and go to the emergency department of the hospital for anti-allergic treatment. You can infuse 10% glucose injection 250ml, add dexamethasone injection 10mg, then add calcium gluconate injection 10ml, and give it to the drip. At the same time, 30mg of fenagine injection should be given intramuscularly, and oral antihistamines such as cetirizine and loratadine can be taken. Patients who are allergic to mangoes are advised to eat with caution.
