Selena Gomez was admitted to hospital after suffering from "malnourishment."
The 18-year-old singer-and-actress—who was hospitalized on Friday (June 10) when she fell ill with nausea and a severe headache—has vowed to take better care of herself in the future after learning her symptoms stemmed from dehydration and an iron deficiency.
She said: "I was very malnourished. I was dehydrated and very low on iron. So, I just gotta take care of myself."
Selena—who has been dating 17-year-old singer Justin Bieber since the beginning of this year—is feeling "much better" following the scare, but was disappointed to have missed out on promoting her new movie Monte Carlo in Santa Monica, California, last week.
She told 'Access Hollywood': "I'm doing great, much better. I was very disappointed I couldn't be here, but I'm here now."
After being admitted to hospital late last week, the brunette beauty reportedly underwent tests for blood pressure problems, and boyfriend Justin was quick to tweet his support for the star.
He wrote: "getwellselena. (sic)"
