Addison’s Disease (Hypoadrenocorticism)

descriptionOverview

Addison’s disease is the opposite of Cushing’s — the adrenal glands don’t produce enough cortisol and aldosterone. Without these hormones, dogs can’t handle stress, regulate electrolytes, or maintain blood pressure. Symptoms are vague (lethargy, vomiting, weakness) and wax and wane, leading to frequent misdiagnosis. An Addisonian crisis (acute adrenal failure) is life-threatening but treatable.

• warningIntermittent vomiting and diarrhea
• warningLethargy and weakness that comes and goes
• warningPoor appetite and weight loss
• warningShaking or muscle weakness
• warningCollapse during stressful events (Addisonian crisis)

restaurantHow Nutrition Helps

Dogs with Addison’s may have electrolyte imbalances — adequate sodium and potassium levels in food are important. High-quality, easily digestible protein supports muscle maintenance. Stress management through consistent feeding schedules helps — Addisonian dogs handle disruption poorly. Some dogs need slightly higher sodium intake than normal.

Regular, gentle exercise is fine for managed Addison’s dogs. Avoid sudden intense activity or stressful situations that can trigger a crisis. Consistent routine is key.
