She looked great at the party! She had a good time.” John Salangsang/Shutterstock Sources told The Blast that Kendall, 22, briefly checked into Cedars Sinai Medical Center in Los Angeles last weekend, when she was treated for the reaction and released a short time later. But a source tells PEOPLE that Kendall may have been experiencing anxiety, something she’s been open about on Keeping Up with the Kardashians.

Benett/Dave Benett/Getty Various vitamin IV drip treatments have risen in popularity among celebrities as part of red carpet prep. Special medical centers like The IV Doc, which treats tens of thousands of patients in 20 cities from Los Angeles to London, have opened, and the vitamin-packed intravenous treatments are said to provide beauty benefits such as fighting acne, weight loss and hair growth. “The primary benefit of treatments can be summed up in one word — balance, ” IV Doc CEO and board-certified physician Adam Nadelson told PEOPLE this week. “Our bodies are constantly striving to find peak physical and hormonal balance and our customized vitamin cocktails provide a streamlined path to achieve that. Our treatments provide immediate hydration and are supplemented with specific vitamin combinations to ensure you reach a perfectly balanced state.” Nadelson — whose center did not treat Kendall — noted that “like any medical treatment, there are always risks,” but extreme reactions like the one Kendall went through are “extremely rare.” This isn’t the first health issue Kendall has dealt with in recent months. The model has been candid about her struggles with anxiety and sleep paralysis due to her high stress job and very public life.
