Deepfake videos impersonating real doctors push false medical advice and treatments
Earlier this year, some of those followers alerted him to a video on another account featuring a man who looked exactly like him. The face was his. The voice was not.
"I just felt mostly scared," Bervell told CBS News. "It looked like me. It didn't sound like me... but it was promoting a product that I'd never promoted in the past, in a voice that wasn't mine."
It was a deepfake – one example of content that features fabricated medical professionals and is reaching a growing audience, according to cybersecurity experts. The video with Bervell's likeness appeared on multiple platforms – TikTok, Instagram, Facebook and YouTube, he said.
A CBS News investigation over the past month found dozens of accounts and more than 100 videos across social media sites in which fictitious doctors, some using the identities of real physicians, gave advice or tried to sell products, primarily related to beauty, wellness and weight loss. Most of them were found on TikTok and Instagram, and some of them were viewed millions of times.
Most videos reviewed by CBS News were trying to sell products, either through independent websites or well-known online marketplaces. They often made bold claims. One video touted a product "96% more effective than Ozempic."
Cybersecurity company ESET also recently investigated this kind of content. It spotted more than 20 accounts on TikTok and Instagram using AI-generated doctors to push products, according to Martina López, a security researcher at ESET.
"Whether it's due to some videos going viral or accounts gaining more followers, this type of content is reaching an increasingly wider audience," she said.
CBS News contacted TikTok and Meta, the parent company of Instagram, to get clarity on their policies. Both companies removed videos flagged by CBS News, saying they violated platform policies. CBS News also reached out to YouTube, which said its privacy request process "allows users to request the removal of AI-generated content that realistically simulates them without their permission."
YouTube said the videos provided by CBS News didn't violate its Community Guidelines and would remain on the platform. "Our policies prohibit content that poses a serious risk of egregious harm by spreading medical misinformation that contradicts local health authority (LHA) guidance about specific health conditions and substances," YouTube said.
TikTok says that between January and March, it proactively removed more than 94% of content that violated its policies on AI-generated content.
After CBS News contacted Meta, the company said it removed videos that violated its Advertising Standards and restricted other videos that violated its Health and Wellness policies, making them accessible to just those 18 and older.
Meta also said bad actors constantly evolve their tactics to attempt to evade enforcement.
Scammers are using readily available AI tools to significantly improve the quality of their content, and viewing videos on small devices makes it harder to detect visual inconsistencies, ESET's chief security evangelist, Tony Anscombe, said.
ESET said there are some red flags that can help someone detect AI-generated content, including glitches like flickering, blurred edges or strange distortions around a person's face. Beyond the visuals, a voice that sounds robotic or lacks natural human emotion is a possible indicator of AI.
Finally, viewers should be skeptical of the message itself and question overblown claims like "miracle cures" or "guaranteed results," which are common tactics in digital scams, Anscombe said.
"Trust nothing, verify everything," Anscombe said. "So if you see something and it's claiming that, you know, there's this miracle cure and this miracle cure comes from X, go and check X out ... and do it independently. Don't follow links. Actually go and browse for it, search for it and verify yourself."
Bervell said the deepfake videos featuring his likeness were taken down after he asked his followers to help report them.
He also said he's concerned videos like these will undermine public trust in medicine.
"When we have fiction out there, we have what are thought to be experts in a field saying something that may not be true," he said. "That distorts what fact is, and makes it harder for the public to believe anything that comes out of science, from a doctor, from the health care system overall."

Draft of White House Report Suggests Kennedy Won't Push Strict Pesticide Regulations
A highly anticipated White House report on the health of American children would stop short of proposing direct restrictions on ultraprocessed foods and pesticides, which the health secretary, Robert F. Kennedy Jr., has called major threats, according to a draft of the document that was reviewed by The New York Times. The report, if adopted, would be good news for the food and agriculture industries, which feared far more restrictive proposals than the ones outlined in the draft. Through his 'Make America Healthy Again' movement, Mr. Kennedy has sought to overhaul the nation's diet by pushing those industries to make major changes. The draft includes an array of policy proposals calling for research into topics like electromagnetic radiation, children's oral health, the role of the microbiome and the health effects of air quality and microplastics. It also recommends government action on a wide range of issues, including initiatives to increase breastfeeding rates, address infertility, promote physical activity and educate the public on the effects of vaping. Questions about a possible push for new pesticide regulations were raised in May when the White House released an initial report, from a presidential commission chaired by Mr. Kennedy, that raised strong concerns about possible links between pesticides and childhood diseases. It also linked the dominance of ultraprocessed foods in children's diets to a range of chronic diseases. Those findings touched off tensions between Mr. Kennedy's movement and Republican lawmakers who have traditionally drawn support from powerful agriculture, food and drug lobbyists. The Times obtained the draft of the new report from a former federal official. An industry official confirmed that it was nearly identical to a copy the administration had recently shown the official at the White House. Kush Desai, a White House spokesman, on Thursday would not verify the draft. At this stage, any draft would go through a number of revisions before it is finalized. The document The Times reviewed was labeled 'pre-decisional' and dated Aug. 6. Called the 'Make Our Children Healthy Again Strategy,' the report comes from the commission led by Mr. Kennedy, which includes cabinet secretaries and agency heads from across the government. The White House has not said when the report will be made public, though it was to have been presented to President Trump on Tuesday, the deadline set by Mr. Trump's executive order establishing the 'MAHA Commission.' The final report is expected to be released in the coming weeks. The draft report says that environmental regulators will work with 'food and agricultural stakeholders' to ensure that the public is aware of and confident in existing pesticide review procedures. It described those procedures as 'robust' and did not propose new restrictions. It also says the Trump administration will back research on technologies to try to help farmers reduce pesticide use and on the health effects of Americans' cumulative exposure to chemicals. After the first report was published in May, agriculture groups, including the American Soybean Association and the National Corn Growers Association, urged the Trump administration to listen to farmers as the commission prepared its follow-up report outlining a strategy. The draft reviewed by The Times does not mention how the proposed research and the new policy initiatives would be funded or how much money might be allocated to them. But it says that the Department of Health and Human Services will form a working group to evaluate 'overprescription trends' involving mental health medications, such as S.S.R.I.s and stimulants, for children. It reiterates Mr. Kennedy's pledge to study the 'root causes' of autism. Mr. Kennedy has spent much of his tenure as health secretary characterizing modern American childhood as a state of stress and sickness, with children mainly eating ultraprocessed food, which he has called 'poison,' tethered to screens and reliant on pills and shots. And he has railed against the pharmaceutical industry, which he says exerts undue influence over scientific research, all while the Trump administration has decimated funding for many academic research programs. Mr. Kennedy has also condemned scientific experts. In June, he fired all the members of an influential vaccine advisory panel. The first report, from May, reflected many of Mr. Kennedy's key talking points. It was heavily scrutinized. While some scientists applauded its focus on flaws within the American food system, many noted it misrepresented the scientific consensus on issues like vaccines. The report also cited studies that did not exist. In recent weeks, Mr. Kennedy's aides and allies have publicized what they described as the administration's most significant steps to improve American health. These include persuading some food makers to phase out petroleum-based food dyes, working with several states to remove soda and candy from their food stamp programs and trying to tighten oversight of food additives. The draft reiterates that the administration will continue these efforts. Some researchers have cautioned that such steps may not do much to improve the overall healthfulness of the American food supply. Ultraprocessed foods, which make up about 62 percent of the calories consumed by U.S. children, are explicitly mentioned in the draft of the second report only once, in a line about the administration's effort to define them. The near-omission of ultraprocessed foods from the draft report raises questions about the administration's appetite for regulation, which the food industry is likely to vehemently oppose. The draft does describe prioritizing 'whole, healthy' foods in federal programs like those providing meals in schools. It suggests offering these foods in 'MAHA boxes' for food stamp recipients. The draft touches on a number of other topics, including vaccines, a focus of Mr. Kennedy's. It says the health department will develop a framework for 'Ensuring America has the Best Childhood Vaccine Schedule.' Mr. Kennedy, one of the nation's most prominent vaccine skeptics, recently pledged to overhaul the nation's system to compensate people harmed by vaccines. Earlier this month, he canceled nearly $500 million in contracts for mRNA vaccines. The draft report also suggests that the government will consider developing guidelines that would limit marketing of unhealthy foods directly to children and will more vigorously enforce restrictions around direct-to-consumer drug advertising. It says the Centers for Disease Control and Prevention will update its recommendations on fluoride in water. On Tuesday, Calley Means, a senior adviser to Mr. Kennedy, spoke at a Heritage Foundation event on the role of agriculture in public health, presenting farmers as key players in American health care. 'We are not going to win if the soybean farmers and the corn growers are our enemy,' he said. There are signs that the report, as drafted, could land with a thud among Mr. Kennedy's followers. In July, 500 people, including leaders of advocacy groups aligned with Mr. Kennedy's movement, sent a letter to Mr. Kennedy and other members of the White House commission urging them to ban pesticides like glyphosate. Hundreds of people tied to the MAHA movement, including Vani Hari, a prominent food activist and MAHA influencer, also sent a letter addressed to Mr. Trump on Monday urging him to take action against protections for pesticide manufacturers. Over the first six months of his presidency, Mr. Trump has largely supported Mr. Kennedy's decisions, after urging him during the campaign to 'go wild' on health. This month, though, after Mr. Kennedy canceled the contracts for mRNA vaccines, Mr. Trump told reporters that the mRNA coronavirus vaccine development initiative from his first term, Project Warp Speed, was 'one of the most incredible things ever done in this country.' He said he had scheduled a meeting with Mr. Kennedy to discuss the cancellations. While Mr. Trump convened the commission, and put Mr. Kennedy at the helm, he does not have to follow its guidance. 'Unlike other administrations, we will not be silenced or intimidated by the corporate lobbyists or special interests,' Mr. Trump said in May during an event celebrating the release of the commission's first report. 'I want this group to do what they have to do.' 'In some cases, it won't be nice, or it won't be pretty,' he added, 'but we have to do it.'

Bindi Irwin reveals major health update: 'Felt utterly ashamed'
Bindi Irwin has shared a major health update in her long battle with endometriosis. Taking to Instagram, the Wildlife Warrior shared a selfie, revealing she was "finally" feeling better after undergoing two major surgeries. "13 years of fighting for answers. 51 endometriosis lesions, a chocolate cyst, and my appendix were all removed across two surgeries with [Dr. Seckin]," she began her lengthy caption. "My hernia from giving birth that was unzipping - was taken care of. I can FINALLY say that I'm feeling better. Genuinely healing. I can function in everyday life without wanting to throw up or pass out from the pain. Slowly, slowly gaining my strength back." She continued, "I cannot express the gravity of my emotions as I am beginning to recognise myself again. I felt utterly ashamed as a teenager and young adult being told that my pain was just part of being a woman. I felt lesser. I felt hurt. I felt weak. That is not ok. "Young girls and women shouldn't feel alone with pain in the driver's seat of their lives. We need to take away the stigma of talking about women's health. It's time to have open discussions and make change on a global scale."

View this post on Instagram A post shared by Not Gonna Lie with Kylie Kelce (@nglwithkylie) What is endometriosis "Endometriosis is a disease in which tissue similar to the lining of the uterus grows outside the uterus," according to the World Health Organisation. "It can cause severe pain in the pelvis and make it harder to get pregnant. "Endometriosis can start at a person's first menstrual period and last until menopause. With endometriosis, tissue similar to the lining of the uterus grows outside the uterus. This leads to inflammation and scar tissue forming in the pelvic region and (rarely) elsewhere in the body." The cause of endometriosis is unknown, and unfortunately, there is no way to prevent it. There is also no cure, and it can only be treated with medication or surgery. Some people will not experience symptoms, but for those who do, it's often pain in the lower part of the belly.

Pain can also be noticeable during a period, during or after sex, or when going to the toilet. Some people also experience: chronic pelvic pain heavy bleeding during periods or between periods trouble getting pregnant bloating or nausea fatigue depression or anxiety Symptoms can improve after menopause, but not always.
