Opposition leader Raila Odinga was on Wednesday treated at Karen Hospital for food poisoning.
Mr Odinga was rushed to the hospital in the morning after feeling unwell.
His spokesman Dennis Onyango confirmed to the Nation that Mr Odinga was treated and discharged.
Last week, Mr Odinga’s second-born daughter Rosemary Odinga was flown out to South Africa for further treatment.
She flew out in the company of her mother Ida Odinga and her younger sister Winnie.
Rosemary had been admitted at the Aga Khan University Hospital after complaining of persistent migraines that got worse.
