Cushing’s Disease In Cats
Hyperadrenocorticism or Cushing’s disease is a condition where the adrenal glands are overproducing and secreting the hormone cortisol. The endocrine system is a collective system of glands that help produce and secrete hormones in the body. Within this intricate system are the adrenal glands. These organs are located near the kidneys and help produce hormones that help regulate bodily functions, one of them being cortisol. Cortisol is a chemical that is responsible for handling stress, control weight, keeping blood sugar regulated and helps to reduce inflammation. When a pet’s body produces too much of this hormone it can cause serious health concerns that could lead to more life threating scenarios. Although this is an uncommon disease for cats to contract, senior aged cats; predisposed breeds or any underlying medical condition can increase your cat’s susceptibility to the disease.
Not all symptoms related to this endocrine disorder are apparent in every cat; warning signs are more difficult to spot during the initial stage of the development. When a cat develops Cushing’s disease, it is usually in concurrence with diabetes. Here is an overview of the most commonly observed symptoms seen in infected cats:
• Increased Thirst
• Excessive Urination
• Weight gain
• Distended abdomen
• Hair Loss
In Healthy Cats, the pituitary gland in the brain produces the hormone adrenocorticotrophic (ACTH), which helps to stimulate the adrenal glands in to secrete cortisol into the bloodstream which helps maintain bodily systems such as metabolism, nervous system, immune system, and kidneys. When there is a benign or cancerous tumor in the pituitary or adrenal gland, it results in excess glucocorticoid being secreted.
There are three forms of Cushing’s disease; adrenal-based hyperadrenocorticism, pituitary-dependent hyperadrenocorticism, and iatrogenic hyperadrenocorticism;
• Adrenal-based hyperadrenocorticism: This condition develops when an adrenal tumor causes an overproduction of glucocorticoids.
• Pituitary-dependent hyperadrenocorticism occurs as a result of the overproduction of ACTH by the pituitary gland.
• Iatrogenic hyperadrenocorticism is developed if a cat has been prescribed excessive amounts of steroid medication for a prolonged period of time
If you suspect your cat has Cushing’s disease, please call to schedule an appointment at your nearest World of Animals Hospital. Blood tests can confirm the condition and your veterinarian can discuss treatment options.
