The condition of former Prime Minister Atal Bihari Vajpayee has shown significant improvement in the last 48 hours, doctors treating him at the All India Institute of Medical Sciences (AIIMS) said on Wednesday.

Addressing the media two days after 93-year-old Vajpayee was admitted to the hospital for urinary problems, AIIMS Director Dr Randeep Guleria said, “His kidney function is back to normal, heart rate, respiratory rate and BP are also normal, they’re being maintained without support.”

“As his urine output was low, a slow dialysis was done,” said Dr Guleria.

The hospital said Vajpayee was expected to make full recovery in the next few days.

“Overall his health is good,” said Dr Guleria, who is supervising the team of doctors treating Vajpayee.

Vajpayee was admitted to AIIMS on 11 June with kidney tract infection, chest congestion and his urine output was on the lower side when he was admitted.

AIIMS had on Monday said the illustrious Bharatiya Janata Party (BJP) leader had been admitted “for examination and management”. On 12 June, AIIMS said the former PM was responding well to treatment.

While Congress president Rahul Gandhi was among the first few visitors on Monday, BJP leaders Vijay Goel and JP Nadda rushed to the hospital to check on Vajpayee’s health, followed by BJP president Amit Shah.

A host of political leaders, including Prime Minister Narendra Modi, RSS chief Mohan Bhagwat and former PMs Manmohan Singh and HD Deve Gowda have visited the ailing leader over the past two days.

Honoured with the Bharat Ratna in 2015, Vajpayee’s health issues began from the time he was the Prime Minister of India, a stroke in 2009 impaired his speech.

Hardly seen in public anymore ever since, Vajpayee has been confined to a wheelchair and reportedly has difficulty in recognising people.

A parliamentarian for over four decades, Vajpayee has been elected to the Lok Sabha (the lower house of Parliament of India) ten times, and twice to the Rajya Sabha (upper house).

Vajpayee was Prime Minister briefly in 1996 and then from 1998 to 2004. He is the first and the only non-Congress leader till date who completed his full term as Prime Minister.

Born on 25 December 1924 in Gwalior, Vajpayee entered politics during the Quit India movement in 1942. He was also the first external affairs minister to deliver a speech in the UN Assembly in Hindi.
