Answer:
Addison's
Step-by-step explanation:
A person diagnosed with Addison's disease cannot produce the required amount of adrenaline in the body. The adrenal glands do not produce the required amount of cortisol.
The treatment of this disease is to replace the hormones that are missing. When a person experiences acute adrenal insufficiency the symptoms of Addison's disease suddenly appear and can be life threatening.
Hence, the statement is referring to Addison's disease.
