Lara was taken to the Global Hospital in Parel, Mumbai at 8am (BST) today.
No further details have been released but a statement is expected in due course.
Lara is in India as a broadcaster for Star Sports, covering the cricket World Cup.
The 50-year-old is considered one of the greatest batsmen of the modern era and holds the record of highest individual Test total of 400.
Tragically, Lara lost his father, Bunty, to a heart-attack and he paid tribute to him after being added to the Halle Of Fame in 2012.
“This person you see today before you accepting this Hall of Fame honour is someone [my father] moulded,” Lara said.
“He ensured that I had everything I needed to succeed as a cricketer and in life, even in trying times.
“He made a special effort to make sure everything was there. I had to work hard… but I knew I had strong support.
“My biggest pain was that he did not see me play a Test match, but having the West Indies team in Trinidad at his funeral was a special tribute to the man who made sure I was given the tools to play this glorious game and make such a lasting contribution.”
Lara made his Test debut in 1990 against Pakistan, his first of 131 Tests and 299 ODIs.
He scored a total of 11,953 and 10,405 runs respectively.
The West Indies star was also the face of the Brian Lara series video game. The final release was in 2007 titled ‘Brian Lara Pressure Play’ and was only available on PSP.
