Finance Minister Arun Jaitley today said he is being treated for "kidney related problems and certain infections" and is currently working from "controlled environment" at home.

Earlier today, reports said Jaitley may have to undergo a surgery soon and has cancelled a visit to London next week for annual economic talks.

In a tweet on Thursday, Jaitley said, the future course of the treatment would be determined by the doctors treating him.

"I am being treated for kidney related problems & certain infections that I have contracted. I am therefore currently working from controlled environment at home. The future course of my treatment would be determined by the doctors treating me," he said on Twitter.

Arun Jaitley, 65, is undergoing diagnostic tests and doctors have so far indicated that it was a kidney-related ailment, sources close to Jaitley said. . The minister, however, has not yet been hospitalised but has been advised to avoid going out in public for fear of infection, they said.

He has not been attending office since Monday and even skipped taking oath after being re-elected as Rajya Sabha MP from Uttar Pradesh. His term as a Rajya Sabha MP from Gujarat ended on April 2.

As many as 55 out of the 58 newly-elected or re-elected Members of Parliament (MPs) took oath of office since April 3. Jaitley was one of the three members who haven't taken oath.

His ill-health has led to cancellation of domestic public appearances as well as foreign visits. While he did not appear at at least two public events in the past one week where he was listed as a speaker, Jaitley's visit to London next week has been cancelled, they said.

The minister, who last month skipped a meeting of finance ministers from the group of 20 countries in Argentina, was to attend the 10th UK-India Economic And Financial Dialogue in London next week. He was scheduled to deliver a talk on 'Looking Ahead to 2022: India's Global Vision' at Chatham House, a policy think tank, on April 12. The talk has been cancelled.

Sources said Jaitley's present condition may be a fallout of the bariatric surgery he had undergone soon after the BJP government came to power at the Centre in 2014.

He underwent the surgery to treat weight gain that he suffered because of a long-standing diabetic condition.

That surgery was first performed at Max Hospital, but he then had to be shifted to AIIMS because of complications.

Sources said doctors from AIIMS are attending to Jaitley at his residence now. A final call is yet to be taken on whether a kidney transplant is required or not, they said.

Depending on doctors advice, he may be admitted to the Cardio-Neuro Tower at the All India Institute of Medical Sciences (AIIMS) here. The centre is housed in a separate building and is equipped with state-of-the-art equipment.

Though he has not been attending office since Monday, he is clearing files from his residence, they said.

The minister, who suffers from chronic diabetes, had heart surgery several years ago. He is a key member of the Prime Minister Narendra Modi's cabinet and presented his fifth and the present NDA government's final full budget on February 1.

The Budget was last month approved by the Lok Sabha without a discussion and it is not listed to be taken up in Rajya Sabha before the current session of Parliament ends tomorrow, thereby not requiring his presence for a reply.
