Feline acromegaly, caused by excess growth hormone from a pituitary tumor, is increasingly recognized as a cause of poorly controlled diabetes in cats and requires specialist management.
Undiagnosed acromegaly in cats causes prolonged suffering through poorly controlled diabetes, requiring frequent insulin injections without achieving stable blood glucose. The underlying growth hormone excess causes progressive organ changes affecting the heart, kidneys, and joints. Cats may experience thirst, hunger, and metabolic discomfort for months or years before diagnosis. Once identified, appropriate treatment can dramatically improve diabetes control and quality of life. Increased awareness among veterinarians and owners is key to earlier diagnosis and reduced suffering.
