Cushing's Disease sa Aso: Kapag Labis ang Cortisol na Ginagawa ng Katawan
Ang Cushing's disease ay nagdudulot ng labis na produksyon ng cortisol sa katawan. Alamin ang mga senyales, diagnosis, at paggamot ng karaniwang kundisyong ito sa endocrine.
Hyperadrenocorticism (Cushing's disease) is a condition where the body produces too much cortisol. It's one of the most common endocrine disorders in middle-aged and older dogs. While it can't be cured, it can be effectively managed, and most dogs with Cushing's live comfortable lives with treatment.
Mga Pangunahing Punto
- Most common in middle-aged to older dogs
- Excess cortisol affects nearly every organ system
- The hallmark sign is increased thirst and urination
- Most cases are caused by a benign pituitary tumor
- Medication (trilostane) effectively manages the condition
- Regular monitoring is essential for safe treatment
What Is Cushing's Disease?
Cortisol is a stress hormone produced by the adrenal glands. In Cushing's disease, the body produces too much. 80-85% of cases are caused by a small, benign tumor in the pituitary gland (at the base of the brain) that signals the adrenal glands to overproduce cortisol. The remaining 15-20% are caused by an adrenal gland tumor.
Recognizing the Signs
The hallmark signs include: dramatically increased thirst and urination (sometimes drinking several liters per day), increased appetite, pot-bellied appearance, hair loss (especially on the trunk), thin skin, muscle weakness, lethargy, panting, and recurring skin and urinary infections. The signs develop gradually, so owners may not realize how much their dog has changed.
Diagnosis
Diagnosis involves blood tests: the low-dose dexamethasone suppression test (LDDS) and ACTH stimulation test are the most commonly used. Additional tests (urine cortisol:creatinine ratio, abdominal ultrasound) help determine whether the cause is pituitary or adrenal. Accurate diagnosis is important because treatment differs based on the cause.
Treatment
Most cases are treated with trilostane (Vetoryl), which blocks cortisol production. The dose is carefully adjusted based on regular blood tests (ACTH stimulation tests). Treatment is lifelong. Your dog will need regular monitoring — initially every 2-4 weeks, then every 3-6 months once stable. With proper management, most dogs do very well.
