( CNN ) -- The human rights activist who entered the 55th day of a hunger strike in Bahrain on Tuesday may not survive the ordeal , his daughter told CNN . Abdulhadi al-Khawaja `` is entering a critical phase , where his life is at stake , '' his daughter , Maryam al-Khawaja said . She said two doctors accompanied her father at all times Monday night , and he was being moved Tuesday to a different prison that has medical equipment he needs . The move is because of fears that he may go into a coma at any time , as his blood sugar and blood pressure have further dropped , she said . On Tuesday , the attending physician at the Correction and Rehabilitation Center recommended that he be transferred to the Public Security Fort for constant medical observation and care , a spokeswoman for the government 's Information Affairs Authority said . The Interior Ministry 's general inspector said Tuesday that `` all policies and procedures of the prison facilities in Bahrain meet international human rights standards and all detainees have consistent and reliable access to professional medical care , '' according to a statement from Maj. Gen. Tariq H. Al Hasan , a spokesman for the ministry . Al Khawaja 's medical condition `` is under constant surveillance '' and he is provided with daily medical care , al-Hasan said in the statement . On 30 March , he was found to have low blood pressure and was taken to Bahrain Defense Force Hospital , where he was treated and returned to Jau Prison the following day , it said . Records showed that Al Khawaja had lost about 10 kilograms ( 22 pounds ) and had a low hemoglobin level , though not critically low . It said he was taking fluids , mineral supplements , glucose and juice on a daily basis . The activist , who was arrested last April for his role in anti-government demonstrations that swept through his country in February and March , has been on a hunger strike for eight weeks to protest his life prison term . In June , al-Khawaja and seven other Shiite opposition activists were found guilty of plotting to overthrow the country 's Sunni royal family . They were sentenced to life in prison . The Bahrain Center for Human Rights , a nonprofit human rights group started by al-Khawaja and for which his daughter works , has appealed for his immediate release on humanitarian grounds . His life is in danger , Maryam al-Khawaja said , `` and getting to a situation where there might be an unrepairable damage to his physical well-being , if he survives . '' Maryam al-Khawaja said he and 13 other detained leaders had their cases taken Monday to the Court of Cassation , where lawyers requested that they be released pending a court decision . The judge refused the request and announced that the decision will be read on April 23 , she said . `` We urge the government to take into consideration the deteriorating health condition of Abdulhadi Al-Khawaja that can not wait until the court 's decision , '' she said . `` Any damage to the health of Abdulhadi Al-Khawaja is the responsibility of the Bahraini government . '' UK Foreign Office Minister Alistair Burt met with officials in Bahrain on Tuesday to discuss progress on reform and human rights issues , the Foreign Office said in a statement . `` We hope that the steps taken so far by the Bahraini government will provide the basis for further reform and will help prevent future abuses from being committed , '' Burt said . `` Reports of ongoing violence and street protests in Bahrain make clear this is ( a ) long-term process and more needs to be done . '' Rights group Amnesty International called Friday for al-Khawaja 's immediate and unconditional release . Phillip Luther , its Middle East and North Africa director , said in a statement : `` The Bahraini authorities have made pledges that they would release people who were imprisoned for exercising their right to freedom of expression , but the continued imprisonment of Abdulhadi al-Khawaja demonstrates that they are not serious about fulfilling such promises . '' The rights group considers al-Khawaja a `` prisoner of conscience , detained solely for exercising his right to freedom of expression , '' and says he began his hunger strike in February to protest his sentence . Last week , the United Nations issued a statement expressing concern about `` the health of human rights defenders who are on hunger strikes in protest against their imprisonment for participating in last year 's mass demonstrations . '' The state-run Bahrain News Agency published a statement Tuesday from the Ministry of Human Rights and Social Development in response to a critical report by another rights group , Human Rights Watch , that said Bahrain had not lived up to its commitments on reform . The ministry dismissed the criticism as rash , saying that the Human Rights Watch report `` had ignored the positive developments in the country and the continuation of the reform process , '' and that it was committed to the protection of human rights . Demonstrations in Bahrain failed to gain the traction of other Arab Spring uprisings after a crackdown by authorities in the island state , backed by troops from nearby Saudi Arabia and the United Arab Emirates . In November of last year , Bahrain 's Independent Commission of Inquiry issued a report critical of authorities ' reactions to the protests , which began in February 2011 , spurred by uprisings in Tunisia and Egypt . The independent commission , set up by Bahrain 's King Hamad bin Isa al-Khalifa , found that between February and April of last year , 35 people were killed in unrest there . Demonstrators and Bahraini authorities have continued to clash in recent months , with the opposition accusing the government of using heavy-handed tactics . CNN 's Samira Said and Mohammed Jamjoom contributed to this report .
