Young Nash diagnosed with Addison's disease

This is little Nash, a delightful Labrador puppy, who is making a fantastic recovery from a very serious illness. Nash was brought to the clinic early one morning after vomiting overnight. Even relatively minor tummy upsets can make young pups very unwell, and Nash's owner knew he was in trouble. Just 5 months old, he was so weak that he couldn't stand up.

Nash was suffering an event called an "Addisonian crisis", where sudden development of Addison's disease causes symptoms including vomiting, diarrhoea, weakness and shock, quickly progressing into life threatening disturbances of the circulation and heart irregularities. The condition occurs when the body's adrenal glands stop producing hormones which are essential for everyday cell functions. A lack of mineralocorticoids results in the kidneys failing to balance sodium, potassium, and water appropriately, eventually leading to shock and heart irregularities. Failure of glucocorticoid (cortisone) production typically causes gastrointestinal signs.

Thanks to the very prompt action of Nash's owners, Nash was given life saving supportive care whilst tests were run, diagnosing Addison's disease. Nash spent over 2 days on an intravenous drip in intensive care whilst his blood electrolytes were corrected and his heart and kidney function recovered. He will be on medication to supply the vital hormones for the rest of his life, and these will need some dose adjustments whilst he grows. The good news is that Nash is expected to lead a full and happy life!
