Ariana Grande Postpones Tour Dates Due To Adult-Onset Allergy: How It Happened

Ariana Grande was in the middle of her "Sweetener World Tour" when she woke up feeling "incredibly sick" causing the "7 Rings" singer to head to a doctor. She shared the news on social media that her concerts scheduled for that night at Amelie Arena in Tampa, Florida, and Wednesday night at Amway Center in Orlando had been postponed.

The next day, Grande gave fans an update on her sickness. She posted an Instagram video captioned, "update: we discovered ..... that ..... i had an unfortunate allergic reaction to tomatoes and my throat pretty much closed."

She went on to let her fans know it "still feels like i’m swallowing a cactus but slowly making progress! thank u all for your love and understanding", before finishing, "p.s. there is NOTHING MORE UNFAIR THAN AN ITALIAN WOMAN DEVELOPING AN ALLERGY TO TOMATOES IN HER MID TWENTIES"

The "Thank You, Next" songwriter is able to continue the "Sweetener World Tour" without canceling any more tour dates at this moment. Live Nation Florida has confirmed the Tampa and Orlando shows have been rescheduled for Nov. 24 and 25, respectively.

Most people find out what they are allergic to early in life. But for some, like actress and singer Ariana Grande, allergies can also develop even once you've entered into adulthood. So how common is it to develop allergies later in life?

According to Prevention, it isn't unheard of. Apparently, the body can develop an allergy to something "even if you’ve had it for years with no problems". Purvi Parikh, MD, an allergist/immunologist with Allergy and Asthma Network, told the publication that, “Allergies develop over time with repeated exposure to a specific allergen until the immune system becomes hypersensitive to it and develops antibodies against it."

Don't confuse an allergy with an intolerance, though. Bruce Lanser, MD, allergist, and immunologist at National Jewish Health, told Prevention that if you have an allergy, it will be consistent. “If you only get a reaction when you eat an entire carton of tomatoes, for example, that often means you have an intolerance, not an allergy.”
