A spokesman for Burma's detained opposition leader Aung San Suu Kyi said Saturday that she is suffering from low blood pressure and dehydration.

Nyan Win, spokesman for the opposition National League for Democracy, said Aung San Suu Kyi's doctor, Pyone Mo Ei, who visited her Friday, put the Nobel Peace Laureate on an intravenous drip to treat her dehydration.

Nyan Win said the doctor has asked authorities for permission to visit Aung San Suu Kyi again.  He added: "We are worried about her health condition."

The Nobel Peace Laureate has been under house arrest for 13 of the past 19 years.

The current term of Aung San Suu Kyi's house arrest is due to expire at the end of this month.  

Earlier this week, Burma's military government rejected an appeal to free her, despite persistent calls for her release from opposition party leaders in Burma and the international community.
