Peres thanked well-wishers Tuesday after checking out of Tel Hashomer hospital near Tel Aviv. He said he was "happy to return to work and excited to serve the country."
Peres completed his seven-year term as president in 2014 but remains in the public eye. He is still active through his non-governmental Peres Center for Peace, which promotes coexistence between Arabs and Jews and peace and development in the Middle East.
In a seven-decade political career, Peres also served three brief stints as prime minister.
