In February 1983, Hamroush graduated with a medical degree (MB BS) from Garyounis University and in December 1999 became a Fellow of the Royal College of Surgeons of Edinburgh.
Dr Hamroush opposed the Gaddafi regime and became a well-known and active member of Libyan opposition from 2008, where she collaborated with many members of the Libyan opposition abroad and inside Libya.
On the 26th of February 2011, she and her son, Abdullah Elneihum, founded the Irish Libyan Emergency Aid (ILEA), a humanitarian aid organisation to provide medical supplies to Libya during the revolution, which assisted in providing medical equipment and consumables during the revolution to almost all areas in Libya.
From November 2011 to November 2012, Dr Hamroush held the position of the Minister of Health in the Libyan Transitional Government. During her term, Dr Hamroush showed remarkable character and intolerance to corruption and, despite the difficult circumstances, she successfully formed foundations for national medical services for her successors.
Dr. Hamroush is also the Head of the Preparatory Committee for the Libyan National Dialogue; an initiative aims to start an inclusive conversation about reconciliation in Libya.
She gave a very impressive speech about the internally displaced people of Tawergha at the UN Refugee week conference at the House of Commons, pointing out fair and clear where we have failed them and what should be done to make the February 17 Revolution succesful.
