At Omega Veterinary Group in San Mateo, we often encounter pet owners who are unfamiliar with Addison’s disease, a serious condition that affects a dog’s adrenal glands. Also known as hypoadrenocorticism, Addison’s disease can be life-threatening if left untreated, but with early detection and appropriate management, affected dogs can lead happy, healthy lives.

What Is Addison’s Disease?

Addison’s disease occurs when a dog’s adrenal glands fail to produce sufficient amounts of the hormones cortisol and aldosterone. These hormones are crucial for maintaining normal body function, especially in response to stress and electrolyte balance in the body. A deficiency can cause a wide range of symptoms that vary from mild to severe, making diagnosis challenging.

Common Symptoms of Addison’s Disease

Because Addison’s disease can mimic other health issues, it is often called “the great pretender.” The symptoms may come and go or become more severe over time. Key signs to watch for include:

  • Lethargy or Weakness: Dogs may appear unusually tired or unwilling to engage in physical activity.
  • Vomiting and Diarrhea: Gastrointestinal issues are common, with recurrent bouts of vomiting or diarrhea.
  • Weight Loss: Despite normal eating habits, dogs with Addison’s disease may lose weight.
  • Increased Thirst and Urination: Frequent drinking and urination may be a sign of hormonal imbalances.
  • Shaking or Trembling: Dogs with Addison’s may experience muscle tremors or generalized shaking.
  • Collapsing or Fainting: In severe cases, dogs can experience acute collapse or shock, known as an Addisonian crisis, which is a medical emergency.

If your dog is exhibiting any of these symptoms, it’s important to schedule a check-up. Our team of experienced veterinarians at Omega Veterinary Group can help diagnose and manage your pet’s condition.

Diagnosis of Addison’s Disease

Diagnosing Addison’s disease requires a combination of clinical signs and diagnostic tests. At Omega Veterinary Group, we perform several tests to confirm the presence of the disease:

  • Blood Tests: Low levels of sodium and elevated potassium are common markers of Addison’s disease.
  • ACTH Stimulation Test: This test assesses how well the adrenal glands are responding to signals to produce its hormones. It is considered the gold standard for diagnosing Addison’s disease.
  • Electrolyte Panels: Imbalances in electrolytes, such as low sodium and high potassium levels, are often indicative of adrenal insufficiency.

Prompt diagnosis is key to preventing more severe symptoms. 

Treatment and Management

Once diagnosed, Addison’s disease is manageable with lifelong treatment. The primary goal is to replace the missing hormones and maintain stable electrolyte levels. Treatment options include:

  • Hormone Replacement Therapy: Your dog will likely need daily or monthly hormone supplements to replace cortisol and aldosterone. 
  • Regular Monitoring: Dogs with Addison’s disease require regular blood tests to monitor electrolyte levels and ensure the medication dosage remains effective.

At Omega Veterinary Group, we work closely with pet owners to develop personalized treatment plans. Regular follow-ups are critical to maintaining your pet’s health, and we offer ongoing support for managing Addison’s disease. 

Living with Addison’s Disease

While Addison’s disease is a serious condition, most dogs respond well to treatment and live normal, active lives. Managing the disease does require vigilance, but with the right care, your dog can enjoy many more happy, healthy years. Be sure to watch for signs of stress, as they can exacerbate symptoms, and always keep up with routine vet visits to ensure your dog’s condition is well controlled.

If you are concerned about your pet’s health or have noticed any changes in their behavior, don’t hesitate to reach out to our team for guidance and support.
