Al-Tamimi was detained from her family home in Ramallah, and sentenced to life on charges of transferring a suicide bomber to Jerusalem.
She heads the Hamas female detainees group in prison, and is currently in isolation at Hasharon prison after she delivered a speech to detainees during Eid al-Fitr.
Al-Tamimi, who studied journalism, is married to Nizar al-Tamimi who received a life sentence in Israeli jail in 1993.
The ministry said al-Tamimi now suffers from severe backache as a result of her detention.
