Burma's police chief has confirmed reports from opposition groups that pro-democracy leader Aung San Suu Kyi has been sick.
Major General Khin Yi said Saturday Aung San Suu Kyi is suffering stomach problems but denied she was hospitalized for treatment.
The U.S. State Department has expressed concern about the reports and urged her immediate treatment and release from house arrest.
Burma's military junta confirmed Friday that Aung San Suu Kyi's house arrest was extended in May for another year. The government said the leader of National League for Democracy remains a threat to the state.
She has been in prison or under house arrest for 10 of the past 17 years.
Her party, the National League for Democracy, won elections in 1990 by a landslide, but the military did not recognize the results and has refused to hand over power.
The U.S. is seeking a UN resolution to pressure Burma to change its policies. But Burmese officials say such a resolution is unacceptable because what is happening in their country poses no threat to the international community.
