Myanmar, May 9: Even as Burma’s detained opposition leader, Aung San Suu Kyi, is facing eating difficulty and has been surviving on intravenous fluid injections, the military government is not allowing a doctor to see the Nobel laureate, her party claims.

Authorities arrested Suu Kyi''s primary physician on Thursday after an American was detained after allegedly sneaking into her closely guarded home and staying there for more than two days.

Another doctor was permitted on Friday to see the 63-year-old Suu Kyi, but his request for a follow-up visit on Saturday was rejected, said a spokesman for Suu Kyi''s National League for Democracy.

“We are worried about Daw Suu''s health. Authorities should allow free access of her doctor to give Daw Suu the required medical treatment,” said Spokesman Nyan Win. "Daw" is an honorific used for older women.

According to the doctor, Suu Kyi had lost her appetite and had not eaten properly for three or four days. He did not specify her illness, the Telegraph reports.

Suu Kyi, whose nonviolent advocacy for democracy won her the Nobel Peace Prize, is one of the world''s most prominent political prisoners. The United Nations and many Western nations have sought her release for long.

Her party won Burma''s last elections in 1990, but the result was not recognized by the military, which has ruled the country since 1962.

On Thursday, Suu Kyi''s primary doctor, Tin Myo Win went to her home to give her a routine monthly check up, but was barred from entering by the police, who increased security there after an American man was arrested after allegedly swimming across a lake to reach Suu Kyi''s compound and sneaking inside

Suu Kyi – who has spent more than 13 of the last 19 years, including the past six, in detention without trial – is allowed virtually no visitors aside from her doctor.

Her home is tightly guarded by police checkpoints and barbed-wire barricades. Sometimes, she is allowed to leave under tight guard to meet with fellow party leaders and visiting UN representatives. (ANI)
