Addison’s disease forms

Adrenal insufficiency is a condition characterized by inadequate production of the adrenal hormones cortisol and aldosterone. Genetic continuity between dogs and humans helps to explain the occurrence of addison’s disease in both species.
The polyendocrine deficiency syndrome is classified into two separate forms, referred to as type I and type II.
Type I occurs in children, and adrenal insufficiency may be accompanied by: underactive parathyroid glands, slow sexual development, pernicious anemia, chronic candida infections, chronic active hepatitis, hair loss (in very rare cases).
Type II, often called Schmidt’s syndrome, usually afflicts young adults. Features of type II may include: an underactive thyroid gland, slow sexual development, diabetes, vitiligo, loss of pigment on areas of the skin.
