YANGON, September 14, 2008 (AFP) - Myanmar's detained democracy leader Aung San Suu Kyi met for several hours with her physician Sunday, witnesses said, amid worries for her health after her party said she was not accepting food.

Doctor Tin Myo Win arrived around 2:00 pm (0730 GMT) at the lakeside home where the Nobel peace laureate has been confined for most of the last 19 years, the witnesses said, speaking on condition of anonymity.

He left four-and-a-half hours later and went to the home affairs ministry, they added.

Aung San Suu Kyi's last medical check-up by the doctor was in mid-August, before her National League for Democracy (NLD) party said September 5 that she had refused most of her food rations for the last three weeks.

Concerns over Aung San Suu Kyi have grown after she refused to meet with visiting UN envoy Ibrahim Gambari and the junta's liaison officer.

The regime says she is not staging a hunger strike, and the NLD has stopped short of using the term.

But the party has said that her refusal of food supplies was 'to denounce her continuing detention, which is unfair under the law.'

The 63-year-old has no other source of food aside from the daily supplies provided by the military regime.

Her party won a landslide victory in a 1990 election but the junta never allowed it to take office. The military has ruled Myanmar since 1962.
