What is Addison's Disease
Addison’s disease in dogs—also called hypoadrenocorticism—is a rare but serious condition that affects hormone production in the adrenal glands. At Animal Care Centers, we help Cincinnati pet parents recognize the early warning signs, understand the causes, and navigate diagnosis and treatment. With locations in Forest Park, Fairfield, Blue Ash, and Anderson, our experienced veterinary team is here to provide expert care for dogs living with Addison’s disease.
What Are The Adrenal Glands & What Do They Do?
The adrenal glands are paired glands next to the kidneys. Each gland essentially consists of an outer cortex and an inner medulla. The glands produce several vital substances which regulate a variety of body functions and are necessary to sustain life. The most widely known of these substances is cortisol, commonly called cortisone, produced by the outer part of the adrenal cortex. Also produced by the cortex and equally important is aldosterone, which is a mineralocorticoid hormone. This hormone regulates the electrolyte and water balance of the body and is involved in the excretion of potassium and retention of sodium.
Deficiency of this hormone together with cortisol is referred to as Addison’s Disease.
What causes Addison's Disease in Dogs?
Signs and Symptoms of Addison's Disease
Signs are usually vague and non-specific. They are often seen in animals with more common medical disorders such as chronic gastroenteritis or renal diseases. There may be vomiting and weight loss. A waxing and waning course with diarrhea, increased thirst and urination is not unusual. Intermittent shaking episodes are also characteristic.
These animals will often improve with non-specific medical treatment. For example, the administration of fluids or corticosteroids appears to help temporarily, but the signs soon return.
What is an Addisonian Crisis?
Sometimes the condition takes on a much more serious form. There is sudden weakness, vomiting, diarrhea and sometimes collapse. This is an Addisonian crisis. Under these circumstances urgent hospitalization will be necessary.
Diagnosing Addison's Disease in Dogs
Treatment & Long-Term Management
Once diagnosis has been positively established, most dogs can be successfully treated with oral medications. Your dog’s diet and activity levels can often remain unchanged. The majority of dogs resume normal lives, ever after a crisis.
It will be necessary to monitor progress carefully, particularly at the start of treatment. This may involve occasionally hospitalization for monitoring and follow-up testing.
It must be emphasized that lifelong replacement of both the glucocorticoids and mineralocorticoids may be necessary. Some of these medications may have to be increased during periods of stress, such as when travelling or if the dog is boarded or has to undergo surgery. In addition we will have to see your pet at fairly frequent intervals to check that stabilization is satisfactory. This may involve further blood tests.
If you wish to discuss long-term costs, please do not hesitate to contact us.
Prognosis for Dogs With Addison's Disease
The vast majority of patients with Addison’s Disease have a good to excellent prognosis once the diagnosis has been established and they have been stabilized with the appropriate drugs. Please do not hesitate to contact us if you have any questions or concerns.
