Adrenal Gland Disease is a common hormonal disease found in pet ferrets, especially those living in North America. Some research suggests as many as 70% of household ferrets suffer from AGD at some point in their life .

In a ferret with AGD, one or both of the glands grow abnormally, or the ferret develops one or more tumors on the gland, which then secretes excess amounts of sexual hormones such as estrogen, testosterone and androgens. The imbalance that is created by these elevated hormone levels is responsible for the onset of symptoms.
