Donald Manford fell ill and collapsed while counting of votes continued on Thursday. The newly re-elected councillor said the “shock of the result” overwhelmed him and his health took a hit.
The Barra and South Uist candidate however received treatment from Paramedics who were called to the Stornoway counting centre.
The SNP councillor is understood to have suffered chest pain. He has since been released from Western Isles Hospital.
Mr Manford said: “Prognoses led medical staff to conclude it was the shock of the volume of support that knocked me over.”
A Scottish Ambulance Service spokesman said: “We received a call at 11.15am on Friday to attend an incident at an address on Springfield Road, Stornoway.
“We sent one ambulance to the scene. One male patient in his sixties was taken to the Western Isles Hospital.”
