Addison's Disease is the common name for Hypoadrenocorticism, which is a rare but serious disorder in which the adrenal glands secrete an insufficient amount of adrenal hormones. Basically, pets with Addison's are unable to produce one or two hormones, so they need to be artificially supplemented.
There are different kinds of Addison's Disease in dogs, Primary/Typical, Primary/Atypical, and Secondary. Medications and treatment will vary depending on what kind of diagnosis you are given.
The most common symptoms of Addison's Disease can be vague at best, and easily confused with symptoms of other health issues. Some of the signs to look for are gastrointestinal disturbances such as vomiting, diarrhea, and poor appetite. Other physical signs may include muscle pain, overall weakness or hind-end weakness and shivering.
When a dog with Addison's Disease is stressed or when their potassium levels are high enough to interfere with the heart, more severe symptoms can be seen. This is referred to as Addisonian Crisis, and involves severe shock, heart arrythmias, and heart stoppage, all of which can be fatal. In some cases (Primary/Atypical or Secondary), there are no changes in the electrolyte balance.
The medications commonly prescribed for Addison's Disease include Florinef (fludrocortisone acetate) and Percorten-V (desoxycorticosterone pivalate or DOCP).
Dogs with Addison's Disease will need medication and monitoring for the rest of their years, however, with proper care they will be able to enjoy a fulfilling, active and happy life!
