Mayim Bialik is opening up about what she described as a “nightmare” experience after trying a GLP-1 weight-loss drug. The “Big Bang Theory” star detailed the frightening side effects, revealing that after taking just one shot of the medication, she experienced severe symptoms that quickly spiraled into what she described as a medical ordeal. Mayim Bialik also shared that she experienced severe gastrointestinal distress.
“To say I had an adverse reaction would be somewhat of an understatement,” she wrote in a candid essay titled “My GLP-1 Nightmare” for The Free Press. “Cramping. Bloating. Full-body aching, as though I had the flu, and an inability to keep down even small sips of water without sprinting to the bathroom with yet more explosive diarrhea.”
Bialik admitted the situation became so severe that she was unable to make it to the bathroom multiple times. “More than three times, I didn’t make it,” she revealed.
The actress said the reaction reminded her of a previous medical experience. “What followed was closer to an allergic reaction, the kind I once had to an antibiotic for a sinus infection, which led me to soil myself without warning and cancel a camping trip to spend the weekend on the toilet,” she wrote. “This was that, but for three days.”
She also described additional side effects, including “sulfur burps so violent they left me afraid to open my mouth in public,” as well as repeated sneezing episodes while trying to eat or drink.
Why Bialik Tried The Drug
Bialik made it clear that her decision to try a GLP-1 medication was not rooted in pressure to lose weight, despite years of public scrutiny over her appearance. “I grew up in the limelight, with my appearance scrutinized weekly from the time I starred in my own NBC show at 14,” she wrote.
The actress reflected on how her relationship with body image shifted over time after being prescribed medication as a teenager to “manage my moods,” which she said contributed to weight gain. By her forties, Bialik said she had developed “a deep sense of shame around my body” and “felt obese” at a size six.
“By the time social media arrived, with its fixation on being thinner, more toned, more surgically perfected, that pressure tipped into a disordered relationship with food that I have spent years trying to untangle,” she explained.
Still, Bialik said weight loss was not the primary motivation behind trying the medication. Instead, she revealed that three different doctors encouraged her to consider the drug because of her ongoing health struggles.
Mayim Bialik Says Health Issues Prompted Decision
Bialik shared that she was diagnosed with Graves’ disease, an autoimmune disorder affecting the thyroid, at age 23. Over the years, she said she was later diagnosed with Sjögren’s syndrome, dysautonomia, connective tissue disease, and mast cell activation syndrome (MCAS), following years of symptoms that included “four unexplained hernias, full-body rashes and welts, severe histamine reactions to foods and smells, palpitations, hourly wake-ups for an entire year” and “crying jags alternating with crippling depression.”
According to Bialik, doctors suggested the medication not because of the “20 postmenopausal pounds” she had gained, but due to growing evidence that GLP-1 drugs may help reduce inflammation tied to autoimmune disorders. “I was exhausted from being sick, from the endless parade of specialists, from the diets, the protocols, and the promises. Maybe this could be the magic cure,” she wrote.
Bialik Says She Quit After One Shot
After experiencing the severe reaction, Bialik said her doctor and nurse told her that intense side effects are not uncommon with GLP-1 medications.
“This drug has a very long half-life; my prescribing doctor had told me to expect at least a week of this, if not more,” she wrote.
Mayim Bialik Was Told GLP-1 Drug ‘Did Not Meet That Bar’
Following the experience, Bialik visited a gastroenterologist, who reportedly warned that GLP-1 medications “are extremely disruptive to the body and should not be used outside of a specific, regulated set of serious medical reasons, namely, life-compromising obesity and its related health consequences” and that she “did not meet that bar.”
Despite the ordeal, Bialik ended her essay with an unexpected moment of reflection, admitting she noticed physical changes after stopping the medication. She recalled catching her reflection in a mirror and noticing that she “did not recoil” because her “second chin” had vanished and her skirt had started to sag.
Bialik is not the only celebrity to speak openly about difficult experiences with GLP-1 drugs. Kris Jenner previously admitted Ozempic made her “really sick” and “nauseous,” while Amy Schumer described her own experience as “horrible” after dealing with severe nausea and vomiting.
