At the Department of Endocrinology and Metabolic Diseases, all conditions within our area of focus are evaluated at every phase, ranging from diagnosis to treatment; we provide patients with the most rational, up-to-date science-based solutions. 

The endocrine system secretes chemical messengers, referred to as hormones within our bodies. Our bodies regulate the response to environmental stimuli via these chemical messengers. These chemicals have a vital role in almost all of our bodily functions, ranging from consumption of water to sleeping, eating and maintaining a regular heart rate. Homeostasis and a feeling of well-being require synergy between all parts of the body.  

The endocrine system covers all of the organs that affect anatomical functions, especially the brain, pituitary gland, thyroid gland, adrenal glands, pancreas, and reproductive organs, as well as the metabolic rate. 

Metabolism refers to the conversion of ingested foods into required energy through a series of reactions or conversions into substances that are vital for anatomical functionality. The human body’s processing of sugar, protein, fat, and vitamins is considered within this scope. Hormones and hormone-like substances form the most important regulators active in this process; the endocrine system and the metabolism function form an integrated and complex pattern.

The Department of Endocrinology and Metabolic Diseases deals with the aforementioned processes including hormones and their interrelations. 

The Endocrinology and Metabolic Diseases team at the American Hospital consist of experienced physicians who have extensive knowledge of all relevant complex processes and closely monitor all global developments in this field; this level of expertise is ideal for providing patients with outstanding evidence-based treatment options supported by contemporary scientific data.

Our physicians are all experts in certain areas of specialization, follow multidisciplinary approaches and exchange ideas whenever necessary. We evaluate our patients more comprehensively with a solution-oriented approach thanks to meetings participated by various departments. We hold meetings at weekly intervals to evaluate our patients in collaboration with our specialized physicians from the Koç University School of Medicine. Our interdisciplinary meetings are as follows:
  • Thyroid council
  • Pituitary council
  • Obesity council

Endocrine diseases may involve all systems of the body. Patients may present with various complaints that originate from the heart, digestive system, eyes or nervous system. Therefore, a comprehensive and detailed examination of patients is crucial.
Numerous complaints, including but not limited to fatigue and tiredness, involuntary weight gain or weight loss, menstrual disorders, abnormal hair growth, and infertility in women; sexual complaints, cardiac rhythm disorders, and changes in physical characteristics in men can originate from diseases of the thyroid gland, adrenal gland, pituitary gland, and gonads. 

Hypertension can be secondary to a disease that originates from or involves the endocrine system.

Diabetes mellitus and organ disorders can be caused by diabetes leading to changes in body weight, polydipsia, polyuria and can cause burning sensations and/or numbness in hands and feet as well as vascular diseases of the heart and brain. 

The Endocrinology Department should also examine patients with osteoporosis and other metabolic bone diseases.

Sexual development disorders and gender identity disorders are followed up and treated in cooperation with other departments.
The endocrine system consists of many organs that secrete different hormones. These hormones affect different target organs in various ways. Organs that form the endocrine system are the pituitary gland, thyroid gland, parathyroid gland, pancreas, adrenal gland, testis, and ovaries. Organs that are not featured on this list which demonstrate different functions such as heart, kidneys, intestine, and brain can behave like “endocrine organs” by secreting hormones. Therefore, endocrinology is a discipline that evaluates the body as a whole and affects all systems. We continuously and regularly cooperate with other departments such as the endocrine surgical department, nuclear medicine department, radiology, and pathology.
