Tom Hanks is living with Type 2 diabetes.
The 57-year-old star of the new film "Captain Phillips" told David Lettterman on Monday evening that he received the news after a recent medical examination.
"I went to the doctor and he said, 'You know those high blood sugar numbers you've been dealing with since you were 36? Well, you've graduated. You've got Type 2 diabetes, young man," Hanks shared.
CBS medical contributor Holly Phillips suspects Hanks' acting career, for which he's put on and lost dramatic amounts of weight to play various character, may have had a role in setting him up for diabetes.
"In dramatic weight gain or dramatic weight loss, the equilibrium of the body is just completely off, so that might predispose him to developing Type 2 diabetes later," she said.
Going forward, Hanks will likely have to be very careful with how he transforms himself. According to the U.S. National Library of Medicine, the best way to manage Type 2 diabetes is through nutrition and exercise.
While Hanks' doctor did try to sell him on one avenue for a cure, the actor has already dismissed it as not possible.
"My doctor said, 'Look, if you can weigh as much as you weighed in high school, you will essentially be completely healthy. You will not have Type 2 diabetes.' And then I said to her, 'Well, then, I'm gonna have Type 2 diabetes, because there is no way I can weigh as much as I did in high school.' "
Hanks then revealed to Letterman, much to the amusement of the audience, that he weighed 96 pounds in high school.
