(CNN) -- New Jersey Gov. Chris Christie has been released from the hospital after having difficulty breathing Thursday morning.
Christie, who suffers from asthma, was admitted to Somerset Medical Center in Somerville, New Jersey, early Thursday after his inhaler did not give him "the kind of relief" he normally gets from using it, the governor said at a press conference after his release.
He decided to go to the hospital after experiencing lightheadedness and difficulty breathing air into his lungs. He said the feeling was similar to the last time his asthma landed him in the hospital, which was while he was attending law school.
Since then, his yearly doctor appointments have kept the condition in check, Christie said.
Hospital employees "ran a whole battery of tests, took a whole lot of blood," he said.
"Everything came back normal," he added.
When asked by reporters if he thought his weight contributed to the incident, he said that "the weight exacerbates everything."
Christie, who is working to lose weight, said he worked out with his trainer on Tuesday.
"The lighter I am, the healthier I will be," he said.
Christie said he plans to be back in the office on Friday morning.
