Addison's disease (or hypoadrenocorticism) is a sneaky endocrine disease that can be confusing as it often mimics other conditions. The disease is results in a reduction in corticosteroid and mineralocorticoid secretion from the adrenal gland.

Deficient production of both these hormones can produce a wide range of often vague symptoms including:

• Vomiting and diarrhoea
• Dehydration and weakness
• Lethargy
• Shaking
• Weight loss and lack of appetite

Patients will often present in an acute crisis and need critical care to save their life.

After they are stabilised, treatment involves daily medication as well as regular blood tests to ensure electrolyte levels are kept in check. Some animals will need additional medication during more stressful times (such as car trips). There is also an injection available that can be given every 25-28 days and many dogs respond very well to this.

Addison's disease is a perfect example of why regular check ups with us are important.

If you notice any changes in your pet (as subtle as you may think they are), it's always a good idea to mention them to us. Routine blood tests may be all that is needed to detect a disease and treatment can start to improve your pet's quality of life.
