Endocrinology and Metabolism

The endocrine system is a complex network of glands that produce and secrete hormones. These hormones are transported through the bloodstream to various parts of the body and regulate many vital functions such as growth, development, metabolism, reproduction, and mood. The endocrine system works together with the nervous system to maintain the body's internal balance (homeostasis) and adapt to environmental changes.

Hormones are chemical messengers that travel through the bloodstream to various parts of the body and act on specific cells, tissues, and organs. They regulate many important body functions such as growth, development, metabolism, reproduction, mood, and sleep. While the nervous system transmits fast and short-term signals, the endocrine system communicates through hormones that have slower and longer-lasting effects.

Endocrinology and Metabolism is a medical specialty within internal medicine that focuses on the body's hormone-secreting glands (endocrine glands) and metabolic processes. Specialists in this field (endocrinologists) diagnose, treat, and manage various diseases caused by hormone deficiencies or excesses, such as diabetes, thyroid disorders, adrenal gland diseases, and pituitary gland disorders.

Diseases related to metabolism, including problems with energy production and utilization (such as obesity and metabolic syndrome), also fall under the scope of endocrinology and metabolism. Therefore, this specialty is critically important for maintaining the body's regular function and homeostasis.

As A Life Health Group, in our Endocrinology and Metabolism Department, a specialized team diagnoses and treats various diseases affecting the body's hormone system (endocrine system) and metabolic processes. Our endocrinology and metabolism department primarily focuses on common health issues such as diabetes, thyroid disorders, hormonal imbalances, and obesity.

Our endocrinologists comprehensively study hormone-secreting glands (thyroid, adrenal, pituitary, pancreas, etc.) and the effects of hormones on metabolism. Since endocrine diseases often cause chronic conditions requiring long-term treatment,

At A Life Health Group, we provide treatment and follow-up services with a multidisciplinary approach tailored to individual patient needs. Our goal is to improve our patients' quality of life and support them in leading healthy lives.

The endocrine system is composed of glands in the body that produce hormones. These glands release hormones directly into the bloodstream, and the hormones regulate the functions of organs and tissues in different parts of the body. Many vital body functions—such as growth, development, reproduction, metabolism, and mood—are controlled by hormones.

Endocrinology studies and treats diseases of these hormone-producing glands and the hormones themselves.

The main areas endocrinology focuses on include:

• Pituitary gland: Produces hormones such as growth hormone, prolactin, and TSH.

• Thyroid gland: Produces hormones like thyroxine (T4) and triiodothyronine (T3).

• Parathyroid glands: Produce parathyroid hormone (PTH).

• Adrenal glands: Produce hormones such as cortisol, aldosterone, and adrenaline.

• Pancreas: Produces hormones like insulin and glucagon.

• Ovaries (in females): Produce hormones such as estrogen and progesterone.

• Testes (in males): Produce testosterone.

Common diseases treated in endocrinology include:

• Diabetes

• Thyroid disorders

• Pituitary gland disorders

• Adrenal gland disorders

• Osteoporosis

• Polycystic ovary syndrome (PCOS)

• Metabolic syndrome

Since the endocrine system affects many body functions, endocrine disorders can lead to a wide range of signs and symptoms, such as fatigue, weight changes, sleep disturbances, mood swings, skin issues, and sexual dysfunction.

Endocrine diseases encompass a wide range of health problems that affect the body's hormone-secreting glands (endocrine glands). These diseases arise from imbalances in the production, secretion, or effects of hormones.

Among the most common endocrine diseases are diabetes (sugar disease), thyroid diseases (goiter, hyperthyroidism, hypothyroidism), adrenal gland diseases, pituitary gland diseases, and bone metabolism diseases (osteoporosis).

Below is a list of common endocrine diseases:

Diabetes, commonly known as sugar disease, is a chronic metabolic disorder that occurs when the body’s ability to produce or use the hormone insulin is impaired. This condition leads to blood glucose (sugar) levels rising above normal.

Insulin is a hormone produced by the pancreas that allows glucose to enter cells and be used as energy. In diabetes, either the pancreas does not produce enough insulin, or the body cannot effectively use the insulin it produces (insulin resistance). As a result, glucose cannot enter the cells and accumulates in the blood, which can damage various organs and systems over time.

The main types of diabetes are: Type 1 Diabetes, Type 2 Diabetes, and Gestational Diabetes. Each has different causes and treatment approaches. Diabetes is a lifelong condition that requires careful management.

Thyroid diseases can manifest in various forms such as the thyroid gland producing too much hormone (Hyperthyroidism) or too little hormone (Hypothyroidism), enlargement of the thyroid gland (goiter), or the formation of abnormal lumps in the thyroid gland (Thyroid Nodules). Thyroid cancer is also a significant health issue that develops in the thyroid gland.

The endocrinology department is responsible for the diagnosis, treatment, and follow-up of diseases related to the excessive or insufficient hormone production of the adrenal glands. These diseases include various conditions such as Cushing's Syndrome (excess cortisol hormone secretion), Addison's Disease (insufficient cortisol hormone secretion), hyperaldosteronism (Conn's syndrome) (excess aldosterone hormone secretion), and pheochromocytoma (excess secretion of adrenaline and noradrenaline hormones).

Pituitary gland diseases encompass various medical conditions that affect the function of the pituitary gland, which plays a critical role in maintaining the body's hormonal balance. The pituitary gland is a small gland located at the base of the brain and produces and secretes many essential hormones. These hormones are involved in numerous fundamental processes such as growth, metabolism, reproduction, and stress response.

The most common pituitary gland diseases include pituitary adenomas (usually benign tumors), acromegaly (excess growth hormone), Cushing's disease (excess ACTH and cortisol), and prolactinoma (excess prolactin).

Metabolic syndrome is a set of metabolic disorders that occur together in the body and significantly increase the risk of cardiovascular diseases and type 2 diabetes. For diagnosis of this syndrome, at least three of the following criteria must be present in a person: abdominal obesity, high blood sugar, hypertension, low HDL cholesterol, and high triglycerides. Endocrinology specialists evaluate the complex mechanisms of metabolic syndrome, such as insulin resistance, fat accumulation, and hormonal imbalances, to diagnose and develop a treatment plan.

Polycystic Ovary Syndrome (PCOS) is a complex hormonal disorder affecting the endocrine system, commonly seen in women. This syndrome leads to hormonal imbalances and metabolic changes, particularly causing ovulation problems in women of reproductive age.

The most prominent features of PCOS include irregular menstrual cycles, excessive hair growth (hirsutism), hormonal imbalances, fertility issues, and infertility. These symptoms are associated with the presence of multiple small cysts in the ovaries (polycystic ovaries) and elevated levels of male hormones (androgens) in the body.

Bone metabolism is a complex process in which the body continuously renews and reshapes bone tissue, with the endocrine system playing an important role in this process. This process is necessary for strengthening bones, repairing them, and maintaining the body's calcium balance.

The endocrinology department specializes particularly in the diagnosis, treatment, and management of bone metabolism diseases such as osteoporosis and osteomalacia. Hormones affect the processes of bone formation and resorption. For example, parathyroid hormone (PTH), calcitonin, vitamin D, estrogen, testosterone, and certain growth factors have direct or indirect effects on bone health.

Endocrine cancers are tumors originating from the body's hormone-producing glands (endocrine glands) such as the thyroid, parathyroid, pituitary, adrenal glands, and the endocrine part of the pancreas. These cancers can affect hormone production, leading to various health problems.

Endocrinology specialists play a key role in the diagnosis, treatment planning, and follow-up of cancers developing in these glands. Examples of endocrine cancers include thyroid cancer, parathyroid tumors, adrenal gland tumors (pheochromocytoma, aldosteronoma), pituitary adenomas (hormone-secreting or non-secreting tumors), adrenal cortex cancers, and endocrine tumors of the pancreas (neuroendocrine tumors - NETs).

The endocrinology department plays an important role in weight control and nutrition because hormones and metabolic processes have a significant impact on body weight and the utilization of nutrients. Endocrinologists can assist patients in managing their weight and adopting healthy eating habits, especially in conditions such as obesity treatment, metabolic syndrome, diabetes, and thyroid diseases.
