The family of TikTok star Taylor Rousseau Grigg has revealed her cause of death.

In a statement issued to Today on Oct. 11, Grigg’s family said the 25-year-old was experiencing complications from asthma and Addison’s disease before her death. The statement came days after her husband, Cameron Grigg, first confirmed on Instagram that his wife’s death was “sudden and unexpected.”

According to the Mayo Clinic, Addison’s disease is a rare disease that “occurs when the body does not produce enough of certain hormones.” Although the symptoms come on slowly, ‘stress, such as illness or injury’ can worsen their effects.

Some of the symptoms include extreme fatigue, weight loss and loss of appetite, nausea, dark skin, low blood pressure, abdominal pain and loss of body hair.

In some cases, the symptoms of Addison’s disease can occur suddenly, known as acute adrenal failure. When they have this condition, people may experience severe weakness, confusion, pain in the lower back or legs, severe abdominal pain, and low blood pressure.

Ashama, another condition Grigg had, occurs when “your airways narrow and swell and may produce extra mucus,” as noted by the Mayo Clinic. While it may be a minor nuisance for some people, for others it can be a major problem that interferes with daily activities, potentially leading to a life-threatening asthma attack.

When Cameron announced his wife’s death last week, he initially did not indicate her health condition. However, he did say that Grigg has “had to deal with more pain and suffering in the past year than most people do in a lifetime.”

“And despite that, she has still been so light-hearted and always brought joy to everyone around her,” he added in his statement on Instagram.

After describing the TikToker as “brave” and “strong” despite the “circumstance she faced,” he went on to share that her body was in the hospital in preparation for organ donation.

“I know she saved my life and so many others. Her earthly body is still here and we are being controlled by machines to keep her organs viable for donation,” his post continued. “More than anything, Taylor would want to know that she continues to save lives even after she is gone from this world. And though her earthly body may have failed her, her memory and life will continue forever.”

The lengthy caption ended with Cameron explaining that “they don’t have anything in order financially” because Taylor was constantly in and out of the hospital and had no insurance. He linked to a GoFundMe page, with donations used to cover the costs of “holding a benefit in Taylor’s honor as she would like everyone who loved her to celebrate her life,” according to the description of the page.

Grigg previously opened up about her health on social media, explaining that she was “fighting for her life” in a TikTok video posted on August 8.

“If I didn’t necessarily know what was happening to me, I would lay in bed in pain and just wish I was dead, because I just wanted it to end, and I don’t necessarily feel that way now like that,” she said.

Although Grigg didn’t share her exact diagnosis at the time, she acknowledged that keeping her health issues private “leaves room for people to make suggestions and tell me what to do.”

Grigg has 1.5 million followers on TikTok. Her death comes a few weeks after she celebrated her 25th birthday, according to a TikTok video she posted on September 9.
