The "Heart Attack" singer was rushed to an emergency room after having trouble breathing, her rep confirms to ET. Prior to going to the hospital, Lovato had been feeling sick for several days with flu-like symptoms.
Lovato has been keeping her health a top priority -- especially after admitting to Fitness magazine this past December that she almost went back to rehab over her issues with food. "I was obsessing over food and terrified of it at the same time," she recalled. "I was done being afraid of food and so tired of overeating and not knowing why I did it. Now I'm on a structured meal plan. I eat four small meals and two snacks a day. It's teaching me portion control."
The "Skyscraper" singer added, "I've learned to appreciate my body for what it is. It helps to remind myself how far I've come."
