D.C. Councilman Marion Barry was admitted to the hospital Tuesday after suffering from a bout of low blood sugar.
The veteran lawmaker -- and the city's longest-serving mayor -- said in a statement posted to his Twitter account that paramedics had taken him to a local hospital. He was expected to remain overnight for observation.
"I'm a 20 year diabetic," Barry posted. "Today, my sugar dipped below normal, and I was taken to the hospital."
Barry said his condition wasn't life-threatening.
Reached by telephone, Barry referred a reporter to his Twitter statements. A spokeswoman for the Ward 8 legislator did not immediately respond to a request for comment.
Barry's personal health has long been a subject of public discussion.
He underwent a kidney transplant four years ago. And while attending a conference in Las Vegas last year as a part of a delegation of D.C. government leaders, Barry was hospitalized with a blood clot.
Barry is also a prostate cancer survivor, has had hypertension for more than two decades and has battled with a drug addiction that a federal judge once characterized as "compulsive."
In a February 2012 interview with The Washington Examiner, Barry said he was in "beyond good health" and that his "greatest deficiency is not enough exercise."
Barry, who served four terms as mayor, won re-election to his council seat in November.
