Gland & hormones

Chemodectoma in dogs is a type of tumor that arises from chemoreceptor cells.

Hyperlipidemia in dogs refers to the presence of excessive amounts of fat (lipids) in the blood, including triglycerides and/or cholesterol. Hyperlipidemia can be primary (inherited, idiopathic) or secondary to something else (e.g., diabetes mellitus, hypothyroidism, Cushing’s disease, kidney disease, certain medications).

Hyperparathyroidism in dogs refers to excessive release of parathyroid hormone from the parathyroid glands. Parathyroid hormone (PTH) is a major regulator of calcium levels in the bloodstream and responds to low blood calcium levels by increasing calcium release from the bones and absorption of calcium from food in the intestinal tract.

Pheochromocytomas in dogs are tumors arising from the cells of the adrenal medulla, which produce large amounts of hormones, such as epinephrine. Nearly half of all cases are asymptomatic and the tumor isn’t detected until a post-mortem examination.

Acromegaly in cats is a disease caused by a growth hormone-secreting tumor of the pituitary gland. Excessive growth hormone affects the entire body, causing abnormal growth of the internal organs (organomegaly), and sometimes the bones of the face and feet.

Hyperparathyroidism is a rare endocrine condition in cats that results from excessive levels of parathyroid hormone. Significantly elevated parathyroid hormone levels lead to symptoms like vomiting, excessive thirst, frequent urination, weakness, limping, and seizures.

Diabetes mellitus, or diabetes, is a common hormonal disorder of dogs, primarily caused by low or absent levels of insulin in the bloodstream.

Addison’s disease (hypoadrenocorticism) is a condition which occurs as a result of a shortage of stress hormones produced by the adrenal cortex.

In a dog with Addison's disease (hypoadrenocorticism), the adrenal glands fail to produce stress hormones due to damage to the adrenal gland or the pituitary gland.

Cushing’s disease (hyperadrenocorticism) is caused by elevated cortisol levels in the bloodstream due either a tumor on the adrenal or pituitary glands or from prolonged administration of corticosteroids.

Diabetes insipidus (DI) is a very rare condition in dogs resulting in the lack of production of antidiuretic hormone (ADH) or a lack of response to the hormone.

Hyperadrenocorticism or Cushing’s disease occurs as a result of excessive cortisol levels. It is a rare condition in cats.

Diabetes insipidus (DI) is a rare disease in cats that should not be confused with diabetes mellitus, or sugar diabetes. DI results from a failure of normal antidiuretic hormone (ADH) signaling

Hyperthyroidism is the most common hormonal disease in cats over the age of 10. It results when the thyroid gland produces excessive thyroid hormone.

Hypothyroidism refers to abnormally low levels of thyroid hormones. The condition is not common in cats,

Hypothyroidism is a common clinical condition in dogs resulting from reduced production of thyroid hormones by the thyroid glands.

Canine hyperthyroidism results from the excessive production of thyroid hormones due to a functional thyroid gland tumor.

In feline diabetes, the body’s cells do not respond to insulin, the major hormone that regulates cellular absorption of blood sugar
