Two and a Half Men Star Jenny McCarthy Opens Up About Her Two-Year Health Battle
Jenny McCarthy has never been one to keep her life private. But the TV personality, who played Courtney Leopold on Two and a Half Men, is now describing the past two years as some of the hardest of her life. That stretch involved repeated surgeries, stubborn infections and what her doctor eventually diagnosed as mycotoxin poisoning from mold.
McCarthy has been talking about the ordeal for months, and her story is once again making headlines as fans learn just how long she quietly struggled behind the scenes.
It Started With a Root Canal
According to McCarthy, the problems began with something many people go through: a root canal.
Speaking on Maria Menounos’ Heal Squad podcast earlier this year, McCarthy explained that the tooth became infected because it had not been fully cleaned out. Three weeks after treatment, she said, her face swelled up again. What followed, in her words, was six months of “living hell.”
The infection spread into her jawbone. McCarthy said doctors found three pockets of infection hidden beneath her wisdom teeth. She went through procedure after procedure, but the infections kept returning. Dental implants placed to replace damaged teeth were rejected by her body.
In a 2025 interview with People, McCarthy said her teeth and implants had been falling out. She said surgeons had to chip away at her jawbone, where they found a deep bone infection. She spent about a year on antibiotics and could eat only soft foods.
By her count, she underwent nine mouth surgeries in 2025 alone.
Strange Growths and Sleepless Nights
The dental problems were only part of it. McCarthy said she began developing painful, recurring growths on her eyelids. On the podcast, she described one in vivid detail as a pus-filled bump the size of a pencil eraser.
When she sought help, she said, she was told she simply needed to wash her eyes more. She didn’t accept that explanation. She had one growth removed, only for it to come back about four weeks later.
She also described severe leg cramps and insomnia as her body struggled to heal.
The Diagnosis
The turning point came when McCarthy’s doctor, whom outlets have described as a functional medicine practitioner, decided to look further. McCarthy recalled the doctor saying she was otherwise one of the healthiest patients in the practice, so something else had to be going on. They tested her for mold.
The results came back positive. Her doctor told her she had mycotoxin poisoning, a condition attributed to toxins produced by certain molds.
McCarthy said her doctor explained that most people with strong immune systems can handle mold exposure. People with weakened immune systems, or with other conditions she said she was already fighting, can be more vulnerable. She said she was told the mold had also made her infections resistant to antibiotics, which would explain why treatment after treatment had failed.
The most frightening moment, McCarthy said, came when her doctor warned that if the toxins crossed the blood-brain barrier, she could end up in the hospital with seizures.
She received the diagnosis in December and began what she calls a “heavy-duty mold protocol” in January, a treatment plan she expects to last up to a year. In the meantime, she has been focusing on diet and exercise to rebuild her strength.
What Doctors Say About “Mold Toxicity”
McCarthy’s account has drawn a lot of attention, and it is worth adding some medical context.
Mold exposure is real and can cause genuine health problems. It is well established that mold can trigger allergies, asthma attacks and respiratory symptoms, and that certain fungal infections can be serious, especially in people with weakened immune systems.
However, “chronic mold toxicity” as a diagnosis, particularly when it is based on urine tests for mycotoxins, is controversial. Many allergists and mainstream medical organizations say those tests have not been well validated and can produce misleading results. Treatment “protocols” for mold toxicity also vary widely between practitioners.
That does not mean McCarthy’s suffering wasn’t real. Her infections, surgeries and symptoms are well documented in her own words. But readers dealing with similar symptoms should talk to a board-certified physician, and ideally get more than one opinion, before starting any long-term treatment.
It is also worth noting that McCarthy has a long history of controversial health views. She was among the most prominent voices linking vaccines to autism, a claim that has been thoroughly debunked by scientific research.
A Familiar Face on Television
McCarthy first rose to fame in the 1990s as a model and MTV host before moving into acting and television. On Two and a Half Men, she played Courtney Leopold, a con artist who became romantically involved with Charlie Sheen’s character, Charlie Harper. The role introduced her to millions of sitcom viewers during the show’s peak years on CBS.
More recently, she has been a judge on Fox’s The Masked Singer and has hosted her own talk and radio shows. She has been married to actor and singer Donnie Wahlberg since 2014, and has credited him with supporting her throughout her illness.
The Show Keeps Making Headlines
McCarthy’s story comes during a busy month for Two and a Half Men nostalgia.
Co-creator Chuck Lorre’s new memoir, Sitcom, offers his account of Charlie Sheen’s erratic behavior and substance abuse during the show’s eighth season, which led to Sheen’s exit in 2011. Meanwhile, Holland Taylor, who played the Harper brothers’ mother Evelyn, recently revealed she stopped signing contracts after six years because she never received a raise, despite four Emmy nominations.
More than a decade after the series ended in 2015, it continues to attract new viewers on streaming, and its stars keep finding themselves back in the spotlight.
Looking Ahead
McCarthy says she is still in the middle of her recovery. She hasn’t given a firm date for when she expects to feel fully herself again, but she has said she is grateful to finally have answers after months of uncertainty.
For fans who remember her as the bubbly, fearless personality from her MTV and sitcom days, her candor about such a painful chapter has struck a chord. Whatever the eventual medical verdict on her diagnosis, her story is a reminder of how much a seemingly routine health problem can upend someone’s life, and how important it is to keep pushing for answers.
