Opposition leader Daw Aung San Suu Kyi is reported to have called on hunger-striking students to call off their protest.
About a dozen detained students have joined a hunger strike calling for the release of all political prisoners in Myanmar, according to the All Burma Students Union on November 14.
One student, Ko Aung Hmine Sann, is being treated in hospital, according to his wife Ma Lai Lai Nwe, who spoke with Mizzima.
He is among dozens of students who were detained in the wake of student protests in Letpadan, following a police crackdown earlier in the year.
Myanmar still has about 100 political prisoners locked up, and hundreds of people facing what are considered by human rights groups to be political charges.
There had been hopes that the ruling government would have released the political prisoners ahead of the November 8 elections. This did not come to pass.
