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

In a statement to Today On Oct. 11, Griggs’ family said the 25-year-old was suffering from complications from asthma and Addison’s disease before her death. The statement came days after her husband Cameron Grigg confirmed for the first time 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 certain hormones in sufficient quantities.” While symptoms tend to come on slowly, “stress such as illness or injury” can worsen the effects.

Symptoms include extreme fatigue, weight loss and loss of appetite, nausea, dark skin, low blood pressure, stomach pain, and hair loss on the body.

In some cases, symptoms of Addison’s disease may appear suddenly, also known as acute adrenal failure. This condition can cause severe weakness, confusion, pain in the lower back or legs, severe abdominal pain, and low blood pressure.

Ashama, another condition Grigg suffered from, occurs when “your airways narrow and swell, potentially producing extra mucus,” as the Mayo Clinic notes. While it can be a minor annoyance for some people, for others it can be a major problem, interfering with daily activities and potentially leading to a life-threatening asthma attack.

When Cameron announced his wife’s death last week, he initially did not provide any information about her health. However, he expressed that Grigg has “endured more pain and suffering in the past year than most people endure in a lifetime.”

“And yet she was still such a light 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 “circumstances she faced,” he then shared that her body was in the hospital in preparation for organ donation.

“I know she saved my life and many others out there. Her earthly body is still here and we are controlled by machines to keep her organs usable for donation,” his post continued. “More than anything, Taylor wants to know that she continues to save lives even after she is gone from this world. And even though her earthly body has failed her, her memory and her life will carry on forever.”

The lengthy caption ended with Cameron explaining that “they are not okay financially” because Taylor was constantly in and out of the hospital and had no insurance. He linked to a GoFundMe page where donations would be used to cover the cost of “a fundraiser in honor of Taylor, as she would love to see everyone who loved her celebrate her life,” it said Description of the page.

Grigg had previously discussed her health on social media, stating in a TikTok video posted on August 8 that she was “fighting for her life.”

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

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

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