What happened to Taylor Rousseau Grigg? Cause of death and diagnoses revealed

Taylor Rousseau Grigg died on Oct. 4 after suffering complications from asthma and Addison’s disease, a representative for her family told TODAY.com in a statement. TODAY.com has reached out to Cameron Grigg for comment.

Addison’s disease, also called adrenal insufficiency, is an uncommon chronic condition that occurs when the body doesn’t produce enough of certain hormones, according to the Mayo Clinic.

In people who have been diagnosed with Addison’s disease, the adrenal glands to make too little cortisol and, often, too little of another hormone called aldosterone.

Symptoms of Addison’s disease can included extreme fatigue, weight loss, loss of appetite, low blood pressure, low blood sugar or hypoglycemia, nausea, diarrhea, vomiting, abdominal pain, muscle and joint pain, irritability and depression.

When sufferers go into acute adrenal failure, they may also experience symptoms such as severe weakness, confusion, pain in the lower back or legs and reduced consciousness or delirium.

Asthma, another condition Grigg had been diagnosed with, causes a person’s airways to narrow and swell and may produce extra mucus, according to the Mayo Clinic.

Asthma can make breathing difficult and can also trigger coughing, wheezing and shortness of breath. In some cases, it can lead to a life-threatening asthma attack.

“It just sucks because I’m 24 years old, 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,” she said.
