Rosie O’Donnell says a prescription medication for weight loss turned her life around after decades of carrying grief, body shame and slow, steady weight gain. The comedian and actress credits the GLP-1 drug Mounjaro with helping her shed pounds and regain energy she felt she had lost long ago.
Why Rosie calls Mounjaro a lifesaver
O’Donnell told People that since starting Mounjaro she’s been losing weight at a steady pace. “I lost a pound or two a month for three years,” she said, noting the change has had deep physical and emotional effects. She described feeling “much healthier and more powerful” in her body.

The 64-year-old also voiced a wish that drugmakers would make the treatment more affordable. She joked she’d rather see the price fall than earn money promoting the drug. That comment underlined a wider frustration around access to GLP-1 medications.
Family grief, scarce groceries and the roots of weight gain
O’Donnell traced part of her weight struggles back to childhood trauma. After her mother’s death in 1973, she recalled how grief affected her household and eating habits.
She described a time when her father handed each child a $100 bill to buy groceries. Shopping on that budget for five people meant choosing cheap, filling options. Entenmann’s pastries and sugary cereals became staples. When the bill crept too high, they left protein behind.
Those choices, she said, were born of sorrow and necessity. “Everyone got heavy,” she reflected, describing a family coping with loss and long-term emotional impact.
Body image, late-night TV and ongoing pressure
O’Donnell spoke about how public life magnified her focus on appearance. Even in moments of success, she said, her first thought was whether she looked “fat.”
She remembered worrying about blazers and camera shots rather than the quality of an interview or performance. The pressure of on-camera scrutiny shaped her relationship with food and self-worth.
Other stars’ experiences with GLP-1 drugs — mixed results
As GLP-1 medications become household names, celebrities share widely different reactions. Some, like O’Donnell, describe steady benefits. Others report disruptive side effects.
Mayim Bialik’s severe GI reaction
Actress Mayim Bialik published a detailed account of her troubles after trying a GLP-1 drug. She described intense gastrointestinal symptoms, including “explosive, uncontrollable diarrhea”, sneezing attacks tied to eating, cramping, bloating and full-body aches.
Jenny Mollen’s bleeding scare and hospital trip
Writer and podcast guest Jenny Mollen said she experienced heavy bleeding and fainting spells while using a GLP-1 in smaller doses combined with other peptides. She recalls a dramatic scene at home before being taken to the hospital. Mollen later suggested hormonal disruption may have played a role.
- Reported side effects across public accounts include:
- Nausea and digestive upset
- Severe diarrhea and cramping
- Unexpected bleeding or heavy periods
- Fatigue, dizziness and fainting in some cases
Why reactions differ and the continuing debate
Doctors note that individual responses to GLP-1 drugs vary. Factors include underlying health issues, other medications, hormonal status and how a person starts or stops the treatment.
Some patients tolerate these drugs well and report substantial weight loss and improved metabolic markers. Others face side effects that force them to stop.
What patients and viewers should know
The growing popularity of drugs like Mounjaro has sparked public conversations on benefits, costs and risks. Celebrities add visibility but their personal stories are not universal.
- Medication effects can be highly individual.
- Stopping and restarting a drug may change how it affects the body.
- Hormonal changes, such as perimenopause, can complicate side effects.
- Cost and access remain major barriers for many people.
For some, like O’Donnell, the medication has brought relief and a regained sense of strength. For others, the road has been rocky, with symptoms that prompted medical visits. Many patients and clinicians say more research and clearer guidance are still needed to understand long-term outcomes and safety.
Voices from those affected and unanswered questions
Public accounts highlight how personally different outcomes can be. Mollen, who suffered heavy bleeding, acknowledged uncertainty about the exact cause. She said she suspected hormones may have played a role, and that cycling on and off the drug probably complicated her experience.
The debate over safety, affordability and best practices continues, and celebrity stories keep the conversation in the headlines as more people weigh the pros and cons of GLP-1 treatments.
