Tom Hanks Reveals Startling Health News On 'Late Show With David Letterman' (VIDEO)

While Tom Hanks was visiting "Late Show," he revealed some big news about his health. According to Hanks, he'd been dealing with high blood sugar numbers since he was 36 years old. He said that his doctor told him, "You’ve graduated. You’ve got type 2 diabetes, young man.”

“My doctor said, ‘Look, if you can weigh as much as you weighed in high school, you will essentially be completely healthy and not have type 2 diabetes,'" Hanks said. "And I said to her, 'Well, I’m gonna have type 2 diabetes.’”

Hanks shared this news after David Letterman commented on his weight -- he was looking noticeably trimmer. While Hanks is in better shape, and thinner than he's been, he said there's no way he could get back down to his high school weight. He joked that he was 98 pounds back then.

Type 2 diabetes is the most common form of diabetes, and Hanks isn't the only celebrity who has it. Patti LaBelle, Drew Carey, Sherri Shepherd and Paula Deen all have been diagnosed with it.

Meanwhile, Hanks isn't letting it slow him down any. He's getting early Oscar buzz for his latest project. He plays a captain of a ship taken over by pirates in the film "Captain Phillips," which is in theaters Friday.

CORRECTION: A previous version of this text misquoted Hanks as saying he has "high blood pressure numbers." He said he has "high blood sugar numbers." The text also stated Hanks plays a pirate in "Captain Phillips," when in fact he plays a captain whose ship gets taken over by pirates. The text has been amended to reflect both changes.
