Congress President Sonia Gandhi, who had gone abroad for a routine medical check-up, returned home Wednesday morning.
Sources said she reached Delhi early morning.
Accompanied by daughter Priyanka, Gandhi had on September 2 left for the US for medical check-up.
66-year-old Gandhi, who had undergone a surgery in the US for an undisclosed ailment on August 5, 2011, had flown there for a check-up in February and again on September 2 last year.
She was admitted to AIIMS in August after she complained of chest pain and exhaustion in the Lok Sabha during a discussion on Food Security Bill when it was in the last stages of adoption.
She was discharged from the hospital after she spent five hours undergoing various tests. Gandhi, who had cough and headache, had felt uneasy in Parliament after taking medicines.
