Why did Dr. Oz get canceled?
What led to the end of The Dr. Oz Show?
- The show ended after 13 seasons, with the final episode airing January 14, 2022 (Los Angeles Times).
- Sony Pictures Television said the show concluded because Oz was focusing on his Pennsylvania Senate campaign (The Hollywood Reporter).
- The show was pulled from some Pennsylvania TV stations after Oz announced his Senate bid (New York Post).
Controversies surrounding Dr. Oz’s medical claims
- In 2014, Oz testified before a Senate subcommittee over his promotion of weight-loss products on the show (The New York Times).
- Medical professionals criticised Oz for unsubstantiated health advice, with some calling his claims “dangerous”.
The show’s cancellation wasn’t purely a ratings move—it was triggered by Oz’s political ambitions, which in turn were fueled by the national platform his TV career had built.
The pattern: Oz’s media platform became the launchpad for his political aspirations, even as it generated the controversies that would follow him.
What is the relationship between Dr. Oz and Trump?
Dr. Oz’s role in the Trump administration
- Trump appointed Oz to lead the Centers for Medicare & Medicaid Services in the second Trump administration (The New York Times).
- Oz was confirmed on April 3, 2025, by a 53-45 vote (Healthcare Dive).
- He was sworn in on April 18, 2025, at the Oval Office (Healthcare Dive).
Dr. Oz’s political campaign and endorsements
- Oz ran for U.S. Senate in Pennsylvania in 2022, losing to John Fetterman.
- Trump endorsed Oz during the Republican primary, calling him “a great doctor”.
Oz’s relationship with Trump is transactional: Trump gave Oz a second political life, and Oz now oversees the health programs Trump promised to reform.
What this means: Oz’s confirmation was a party-line vote, cementing his role as a key executor of the Trump health agenda.
Does Oprah still have a relationship with Dr. Oz?
Origin of Dr. Oz’s television career with Oprah
- Oz appeared on The Oprah Winfrey Show more than 55 times, and Oprah served as an executive producer for the first season of The Dr. Oz Show.
- Oprah’s endorsement was critical to Oz’s early success in television.
Current status of their personal and professional relationship
- Oprah publicly distanced herself from Oz in later years, especially after the controversy over his medical advice.
- Private status of their relationship remains unclear.
“I think he’s a good doctor, but I don’t always agree with him.”
— Oprah Winfrey, in a 2014 interview cited by The New York Times
Is Dr. Oz a Turkish citizen?
Dr. Oz’s dual citizenship status
- Oz was born in Cleveland, Ohio, to Turkish immigrant parents.
- He holds both U.S. and Turkish citizenship (The New York Times).
- Claims that he renounced U.S. citizenship are false.
Dr. Oz’s family background and Turkish ties
- His father was a surgeon who emigrated from Turkey.
- Oz served in the Turkish military? He was drafted but exempted from service.
Oz’s dual citizenship became a political liability during his Senate campaign, yet it also connects him to a key NATO ally at a time of global health cooperation.
The implication: The dual-citizenship issue is unlikely to fade, but it has not prevented his rise to a senior health policy role.

Dr. Oz now sits at the helm of the largest health payer in the United States. For the 160 million Americans covered by Medicare, Medicaid, and CHIP, the implications are direct: his decisions on price transparency, chronic disease management, and fraud reduction will shape their out-of-pocket costs and access to care. For the healthcare industry, the choice is clear: adapt to a regulator who knows the media playbook, or face tougher enforcement.
