Waving Georgian flags and chanting Saakashvili's name, protesters gathered on Saturday evening outside the prison in Georgia's southeastern city of Rustavi, where the former president is held.
Georgia's president from 2004-2013, Saakashvili was arrested on October 1 upon his return from exile in Ukraine. He has refused food for 37 days to protest his imprisonment, which he says is politically motivated.
The jailing of the country's foremost opposition leader has further fuelled a protracted political crisis that gripped Georgia last year after the opposition denounced fraud in parliamentary elections won narrowly by the ruling Georgian Dream party.
The protesters have vowed round-the-clock permanent protests until Saakashvili is transferred to a hospital, as recommended by medics.
"Saakashvili's life must be saved," Nika Melia, the chairman of his United National Movement -- the country's main opposition party -- told the crowd.
"We give the government 24 hours to transfer him to a civilian hospital.
"If the demand is not met, all of Georgia will gather on Monday in (Tbilisi's) Freedom Square," he said.
"Our struggle will be unrelenting, peaceful."
'Serious complications looming'
In a statement released through his lawyers, Saakashvili said Saturday that his "health condition has significantly worsened and serious complications are looming."
Doctors have said Saakashvili faces an imminent risk of death as he has an underlying blood disorder that makes his hunger strike particularly dangerous.
But Georgia's health ministry has rejected their recommendation to hospitalise him.
Prime Minister Irakli Garibashvili has said the former president will be transferred "if need be" to a prison medical facility. According to the country's rights ombudsperson such a facility fails to meet hospitalisation criteria defined by medics.
Garibashvili sparked an uproar recently by saying that Saakashvili "has the right to commit suicide" and that the government had been forced to arrest him because he refused to quit politics.
In the largest anti-government demonstration in a decade, tens of thousands rallied last month in Tbilisi to demand Saakashvili's release.
Mass pro-Saakashvili rallies were also held in several major cities across Georgia.
Critics have accused Georgian Dream of using criminal prosecutions to punish political opponents and journalists.
