India's opposition leader Sonia Gandhi admitted to hospital again

India's main opposition Congress party chief Sonia Gandhi has again been admitted to a hospital in the national capital.

The 69-year-old was admitted to Sir Ganga Ram Hospital, a leading private hospital in Delhi, Thursday afternoon and she will be there for a couple of days for treatment, doctors said Friday.

"Gandhi is undergoing physiotherapy and rehabilitation in the hospital. Although she is doing well, we will keep her under watch for a few days," a doctor said, on condition of anonymity.

The Congress president was discharged from the same hospital Sunday, more than 10 days after she was admitted there with fever, dehydration and shoulder injury.

Gandhi had been shifted there on August 3 from Army Hospital, a day after she fell ill during a roadshow in Indian Prime Minister Narendra Modi's parliamentary constituency of Varanasi.

She had reportedly sustained a shoulder fracture during the roadshow in the northern state of Uttar Pradesh and also underwent a surgery on her left shoulder at the same hospital.

In 2014, Gandhi was admitted to a Delhi hospital for treatment of an infection. And in 2013, she was taken to a hospital for a few hours after she fell ill in the Indian Parliament.

In 2011, she went to the United States to get surgery for an undisclosed medical condition. Neither the then Congress government nor the party had released any details of her operation.

Gandhi is the widow of former Indian Prime Minister Rajiv Gandhi. She is also the head of Congress-led United Progressive Alliance that lost the general elections in 2014 to Modi's Bharatiya Janata Party. Endit
