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

Taylor Rousseau Grigg died Oct. 4 from complications of 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.

According to the Mayo Clinic, Addison's disease, also called adrenal insufficiency, is a rare chronic condition that occurs when the body does not produce enough certain hormones.

In people diagnosed with Addison's disease, the adrenal glands produce too little cortisol and often too little of another hormone called aldosterone.

Symptoms of Addison's disease may include 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 people experience acute adrenal failure, they may also experience symptoms such as severe weakness, confusion, pain in the lower back or legs, and impaired consciousness or delirium.

According to the Mayo Clinic, asthma, another condition Grigg was diagnosed with, causes a person's airways to narrow and swell, potentially producing extra mucus.

Asthma can make breathing difficult and can also cause coughing, wheezing and shortness of breath. In some cases, a life-threatening asthma attack can occur.
