An ACTH (adrenocorticotropic hormone) test taken on Monday confirmed that Jack has Cushing's Disease. He has had that waspy waist look about his hips for some years, and been confusingly fat (pads) and thin (ribs) at the same time. However, his original test was negative.
Cushing's, which is also known as PPID (Pituary Pars Intermedia Dysfunction), is a hormonal disorder which affects the pituitary brain and causes symptoms in many older horses and ponies such as long curly hair, weight loss, laminitis, increased thirst and urination, and infections.
Other than long, but not curly, hair which takes a long time to moult in the spring, and his general shape, Jack shows none of the other signs but his reading was very high. He will be retested in four weeks. As he is bright and happy in himself, hopefully we can manage his condition with Pergolide, a tablet, for the rest of his life.
While my horses and ponies are happy and comfortable then I will remain on this earth, but I don't want any of them to go through chronic pain like I have.
Just off for another little cry...
