Dave Coulier said on Thursday that dave coulier has lost 45 pounds while undergoing cancer treatment that has kept him from eating solid food for months. He also said the radiation he received in his throat has affected the way he speaks.
Coulier’s 45-Pound Drop
"I haven't posted in quite a while, and the last time I did some of you said that I look differently and I sound differently, and I do," he said on social media. "What you're seeing is the side effects of extensive radiation that I went through carcinoma in my throat."
"I haven't been able to eat solid food in months, and so I've lost 45 pounds," Coulier said. "That's what you're seeing, and it's affected my ability to speak." Those are the kinds of changes viewers noticed in his recent appearance, and he addressed them directly rather than letting the speculation stand.
December Radiation
35 rounds of targeted radiation in December followed a cancer history that already included stage 3 non-Hodgkin lymphoma in 2024 and HPV-related oropharyngeal tongue cancer a year later. At a six-month checkup after his first diagnosis, doctors found an enlarged tumor during PET scans, and Coulier said that tumor was later found to be unrelated to his lymphoma.
In February, he said he was in remission after battling two cancer diagnoses in the last two years. That matters because the new weight loss is not presented as a standalone health update; it lands against a record of repeated treatment and follow-up testing that has already shifted his diagnosis once.
PET Scan Results
"But just to recap, a year and a half ago I had non-Hodgkin's lymphoma and I went through chemotherapy, and my hair is kind of growing back. And we got our PET scans back, and the prognosis looks good for both the carcinoma in my throat and the lymphoma. So we're very pleased with all of that," he said.
For Coulier, the immediate takeaway is plain: the treatment has taken a physical toll, but the scan results gave him a better read on both cancers. The next issue is how quickly he can regain strength and normal eating after months without solid food, because the weight loss is now part of the story he is publicly managing.
