 How Dr. AvRuskin will help you
Dr. AvRuskin analyzes each patient's case and recommends the best treatment and options for each person.  He uses the latest research and developments in medical science, as well as his decades of clinical experience and knowledge, to help each patient develop his/her individual treatment strategy. 
He is both a pediatric endocrinologist and an adult endocrinologist; he treats persons of any age suffering from endocrine, metabolic and hormonal diseases.


What is endocrinology?
Endocrinology is the study of glands, the substances they secrete (called "hormones"), and the diseases that gland abnormalities cause. 

The organs in the human body that are endocrine glands are the pancreas, thyroid, parathyroid, pituitary, adrenal, bone, brain, testes, and ovaries.

What is an endocrinologist?
 An endocrinologist is a medical doctor (M.D.) who treats diseases and abnormalities of the endocrine glands.
A pediatric endocrinologist treats the endocrine diseases of children.  An adult endocrinologist treats endocrine diseases of adults.

 An endocrinologist will talk with a patient about his/her symptoms, do a physical examination, order specific laboratory tests, analyze the findings of all tests and discuss the best treatment choices and options with the patient. 

Sometimes an endocrinologist is called a "diabetes doctor" or "diabetes specialist", but an endocrinologist treats all abnormal hormonal and metabolic conditions.

What is the treatment for diabetes and other endocrine conditions?
 Many endocrine or hormonal disorders are helped tremendously by prescription medication.  In some cases, surgery is recommended. 

While diabetes treatment can include insulin injections and oral medication, exercise and nutrition management are absolutely essential components of treatment to optimize the health of a person with diabetes.
