TikToker Taylor Rousseau Grigg's Cause of Death Revealed

Taylor Rousseau Grigg's cause of death has been determined.

The TikToker died on Oct. 4 at age 25 after suffering complications from asthma and Addison’s disease, a spokesperson for her family told TODAY.com.

Addison's disease is an uncommon chronic condition that occurs when the body doesn’t produce enough of the cortisol and aldosterone hormones, according to the Mayo Clinic. The illness is also known as adrenal insufficiency, as it affects the adrenal glands of the kidneys. It can be fatal if left untreated, per the NHS. 

Prior to her death, Taylor was open about her health journey as well as her life as a self-described "asthmatic." In an Instagram post shared in March, the Texas-based influencer shared several photos from a hostpital bed, including a snapshot of herself hooked into what appeared to be a breathing machine.

"My good days may look different than yours," she wrote in the caption, "but my bad days remind me how precious the good ones of mine truly are."

Taylor later shared that she had received a "forever diagnosis," but did not specify her exact illness.

"It just sucks," she said in an Aug. 8 TikTok. "I should be in my prime. I should be able to carry my suitcase up the stairs. I should be able to walk to the mailbox—or run—and those are just things that I can’t really do right now." 

According to the Taylor, she "got sick" shortly after her 2023 wedding to husband Cameron Grigg.

In the wake of her passing, Cameron praised Taylor for her enduring spirit despite being "dealt with more pain and suffering than most people do in a lifetime."

“No one ever expects to have to deal with this kind of pain and heartbreak, especially at our age," he wrote in an Oct. 5 Instagram post. "She is the most brave and strong woman I know, and her confidence in the Lord outweighed every other circumstance she's faced, even in her darkest hours. I know she’s saved my life and so many others out there."

The 24-year-old added, "And even though her earthly body may have failed her, her memory and life will be carried on forever."
