Hormonales

Addison's disease (hypoadrenocorticism)

The adrenal glands produce too little hormone. It is known as "the great imitator" because its symptoms are vague and intermittent. An acute crisis is a life-threatening emergency.

Severe🐕 Dogs

This may be a veterinary emergency

URGENT if there is collapse or extreme weakness. On a non-urgent basis, suspect Addison's if your dog has repeated episodes of lethargy and digestive problems that "come and go".

Symptoms to watch for

  • • Lethargy and weakness that come and go
  • • Intermittent vomiting and diarrhoea
  • • Loss of appetite, weight loss
  • • Trembling
  • • Worsening under stress
  • • Acute crisis: collapse, shock (life-threatening emergency)

Causes

Destruction of the adrenal glands, almost always by an immune-mediated process. It mainly affects young to adult dogs. There is a breed predisposition.

Diagnosis

Blood tests (characteristic electrolyte disturbances) plus a specific hormonal test (ACTH stimulation test) that confirms the diagnosis.

Treatment

Lifelong treatment with the missing hormones. When well controlled, the dog leads a completely normal life. An Addisonian crisis is an emergency requiring hospitalisation.

Prevention

Not preventable. Early clinical suspicion prevents progression to an acute crisis.

When should you see the vet?

URGENT if there is collapse or extreme weakness. On a non-urgent basis, suspect Addison's if your dog has repeated episodes of lethargy and digestive problems that "come and go".
