Supermodel Gigi Hadid has sparked plenty of trends. She rocks crop tops, miniskirts and athletic-wear like few others. Her latest must-have headline maker? Hashimoto’s disease.

The exotically named thyroid condition — known to cause hair loss, skin flaking and weight gain — is treated with medication that wound up making Hadid look even thinner than usual in late 2016.

Celebrity illnesses such as this one can raise awareness of a particular disease and make the malady almost fashionable. Genetic testing referrals for breast cancer spiked after Angelina Jolie underwent a double mastectomy. When Katie Couric aired her colonoscopy live on the “Today” show in March 2000, a 20 percent jump in people undergoing the odious procedure followed.

Now, some in the medical community are girding for patients fearing that they may have Hashimoto’s.

“When a disease is in the headlines, people become sure that they have it,” says Dr. Barron Lerner, a medical historian with NYU Langone Medical Center and author of “When Illness Goes Public.”

And because the symptoms of Hashimoto’s are vague, people can easily guess that they’re afflicted.

“I have patients who are prone to wonder why I am not doing the tests that, say, Gigi Hadid had,” says Lerner. “Sometimes I say it’s ridiculous. Other times I think it’s worth doing the tests.”

“It sounds frivolous to get your health information from celebrities, but people pay attention,” Lerner adds. “They feel a connection and believe that celebrities have resources to see the best doctors and get the best advice.”

Far more troubling is the concern that young women will actually desire the slim physique flaunted by Hadid and be cognizant of how she got it.

“Nobody wants an illness but some may want the effects of the illness,” says Dr. Guido K.W. Frank, author of “What Causes Eating Disorders, and What Do They Cause?” and a professor at University of Colorado.

According to Dr. Ovidio Bermudez, chief clinical officer at Eating Recovery Center, people who already have Hashimoto’s may do what they can to turn the disease into a diet plan. “The bigger fear is that people getting diagnosed with Hashimoto’s will overuse the medication to bring on weight loss.”

Although social media and the 24/7 news cycle goose all of this along, the celebrity effect, and the fashionableness that comes with it, is nothing new.

In the early 1800s, the British poet Lord Byron mused that he would like to die of consumption.

When asked why, he responded, “The ladies would all say, ‘Look at that poor Byron, how interesting he looks in dying.’”

According to Dr. Daniel Williams, a special lecturer at Columbia University and a psychosomatic disease specialist, it’s human nature to relate to famous people.

“We respond to dramatic medical stories with curiosity, interest, anxiety and possibly misguided information,” says Williams. “We live in an age where a lot of things get publicized and they can have unintended consequences.”

Such was the case after Charlie Sheen publicly admitted having contracted HIV. Some in the HIV community felt that Sheen’s wild ways added to the stigma of living with the condition. But one beneficiary of Sheen’s confession was the HIV testing site STDcheck.com.

“We had a 50 percent surge as soon as the news came out,” says Fiyyaz Pirani, the site’s CEO.

Where Hashimoto’s is concerned, there’s a sense that Hadid will be an effective representative of the disease and a help to those with it.

“Overall, it is good [for Hadid to have come out],” says Maggie May Ethridge, a 42-year-old writer based in San Diego who has Hashimoto’s. “She brings a common disease into public awareness and gets people talking about it.”

Paola Mata, a 35-year-old software engineer from Brooklyn, who also has the disease, agrees that the awareness of her condition and the destruction it brings need to be elevated.

“I told a guy I was dating that I have Hashimoto’s, and he just started laughing,” she says. “He thought it sounded like a martial-arts move.”
