Sam Milby has revealed that he has been diagnosed with latent autoimmune diabetes in adults (LADA)—a condition often referred to as Type 1.5 diabetes.
The actor shared the update about his health in an exclusive interview with MJ Felipe of ABS-CBN News during the 20th anniversary celebration of his talent agency, Cornerstone Entertainment, on Wednesday, October 29, 2025.
Months earlier, Sam shared that he had Type 2 diabetes. But after a general medical checkup in Singapore, doctors confirmed that his condition was actually Type 1.5.
"There was a fan who messaged, made a comment na, ‘Maybe you’re not Type 2, maybe you’re Type 1.5,’" Sam recalled.
"So I did my research also and I asked my endo [endocrinologist]. I had my check-up in Singapore and the two doctors said that they’ll do a blood test to make sure—and it was confirmed.
"It’s called LADA—it’s an autoimmune disease, and it means that I am diagnosed as Type 2, but eventually magiging Type 1 ako."

When asked about the seriousness of his condition, Sam was candid.
"It’s bad. Type 1 is the worst. Tito Gary [Valenciano] has Type 1. It means that your pancreas does not produce insulin at all.
"So I may have to start insulin shots eventually. Ganun talaga," the actor said.
Despite the diagnosis, Sam remains positive and grounded.
He said, "It’s part of my life. I have discipline naman sa pagkain, but it was a bit surprising kasi para sa akin, healthy naman akong tao.
"Nakaka-sad, but it’s a part of my life."

Sam practices a healthier lifestyle
To manage his condition, Sam shared that he plans to be more physically active and maintain a balanced diet.
"I am trying to be more physically active. During the pandemic, hindi masyado, e. I would do some push-ups and sit-ups pero cardio kulang. Hindi ako mahilig sa treadmill, e.
"Well, I do pickleball now. I’ve been playing pickleball on and off for two years. That’s my cardio. Sometimes I run.
"Also, eating habits—I’m pretty strict on my diet. The one thing that helps also is shiratake rice and shiratake pasta, okay siya, masarap siya. That’s a big help."
What is LADA?
According to the Mayo Clinic, latent autoimmune diabetes in adults (LADA) is a type of diabetes that starts in adulthood and slowly gets worse over time.
Like Type 1 diabetes, LADA happens when the pancreas stops producing insulin because an autoimmune process attacks the insulin-making cells.
But unlike Type 1, the process happens gradually—so people with LADA often don’t need insulin right away.

Earlier diagnosis
It was in June 2024 when Sam publicly revealed that he had been diagnosed with Type 2 Diabetes Mellitus (T2DM).
In his Instagram post, he shared his shock given his lifestyle and family history.
“I don’t have a sweet tooth, bihira din mag junk food, pero last year I found out na may Type 2 diabetes na ako.”
Despite not having any genetic predisposition, Sam emphasized the importance of early detection.
“My parents and grandparents never had it. I just wish I got checked up earlier nung pre-diabetes pa.”
With that, he urged his followers to listen to their bodies and get tested regularly, especially if experiencing symptoms like excessive thirst and frequent urination.
