Chrissy Teigen rarely shies away from sharing updates about her personal life on social media—and over the weekend she let her followers know about the reaction she suffered after flying from Los Angeles to Utah for the wedding of her friends Meghan Mackenzie and Luke Dillon. In a series of tweets, Teigen explained the condition is called angioedema, which she believes is due to altitude sickness. Not only did it cause her mouth to feel like it was "about to explode," but photos show her bottom lip swollen to almost twice the normal size.

According to the Mayo Clinic, angioedema causes the deeper layers in your skin to swell as a result of an accumulation of fluid and usually affects loose tissue areas like the eyes and mouth.
