Endocrine Disorders & Skin Disease in Dogs and Cats
- by BluePearl Specialists
Healthy skin and a normal hair coat are a result of many factors, both internal and external.
The body contains several glands, which secrete hormones into the bloodstream. These glands and their hormones are called the endocrine system.
The hormones are vital to normal skin and hair coat production and are necessary for the regulation of other body functions.
A common cause of skin disease is a failure of an endocrine organ to secrete the proper amount of its hormone. This usually results in some degree of hair loss and abnormal skin quality. Depending on the hormone involved, there may be other subtle changes noted in the pet’s history or found on the physical exam.
This information may help us decide which organ is most likely involved and thus direct our testing. Hormonal disorders usually carry a good prognosis. Some are treated with lifelong medication, while others are cured surgically.
The following is a brief summary of the endocrine disorders which may cause skin disease in dogs and cats:
Cause: Insufficient thyroid hormone production
Cause: Excessive cortisone production by the adrenal gland or a pituitary (brain) problem
Cause: Abnormal estrogen, progesterone or testosterone levels
Cause: Unknown at this time, but it is believed to be related to photoperiod (length of day)
Please note that all the signs may not be present. Also, these disorders can mimic one another, so that it may be necessary to test for multiple endocrine disorders.
