Which diseases I diagnose and treat?

Diagnosing and treating patients with benign and malignant tumors of endocrine glands (pituitary, thyroid, parathyroid and adrenal glands) and neuroendocrine tumors made me a well-established endocrinologist. These are some of the diseases in the field of endocrine oncology that only few endocrinologists in Croatia have sufficient experience with:

  • Pituitary tumors and cysts
  • Prolactinomas
  • Acromegaly
  • Cushing’s disease
  • Nonfunctional pituitary adenomas
  • Hypopituitarism (insufficient hormone secretion from the anterior pituitary lobe)
  • Diabetes insipidus (insufficient anti-diuretic hormone secretion from the posterior pituitary lobe)
  • Rare pituitary diseases (hypophisitis, sarcoidosis, histiocytosis, metastases)
  • Papillary and follicular thyroid carcinoma
  • Medullary thyroid carcinoma
  • Adenoma and carcinoma of parathyroid glands
  • Adenoma and carcinoma of adrenal glands
  • Cushing’s syndrome (excessive cortisol secretion from the adrenal gland)
  • Primary hiperaldosteronism (excessive aldosterone secretion from the adrenal gland)
  • Pheochromocytoma
  • Paraganglioma
  • Neuroendocrine tumors (carcinoids) of the lung, pancreas and gut
  • Carcinoid syndrome
  • Insulinoma
  • Gastrinoma
  • Multiple endocrine neoplasia type 1 and 2
  • Von-Hipple Lindau syndrome


Expertise in dealing with the aforementioned, most complex, endocrine diseases implies sufficient expertise in common endocrine diseases as well:

  • Hypothyroidism and hyperthyroidism (insufficient or excessive thyroid hormone secretion)
  • Hashimoto’s thyreoiditis (autoimmune thyroid disease)
  • Subacute de Quervainov thyreoiditis (bacterial or viral inflammation of the thyroid gland)
  • Thyroid disorders in pregnancy
  • Nodular goiter of the thyroid gland
  • Functional and nonfunctional thyroid adenomas
  • Hypoparathyroidism and hyperparathyroidism (insufficient or excessive PTH secretion)
  • Osteoporosis
  • Blood electrolytes imbalance (increased or decreased serum calcium, potassium and sodium)
  • Irregular menstrual cycle (polycystic ovary syndrome)
  • Insulin resistance and prediabetes
  • Type 1 and type 2 diabetes mellitus
  • Obesity
  • Hypoglycemia (low plasma glucose in patients with or without diabetes mellitus)
  • Adrenal insufficiency (insufficient secretion of adrenal gland hormones)
  • Male hypogonadism (insufficient testosterone secretion)
  • Preterm menopause


Patients may seek endocrinologist’s help if they experience any of the following symptoms:

  • Palpitations
  • Excessive sweating
  • Anxiety
  • Hair loss
  • Excessive fluid intake and urination
  • Weight loss
  • Weight gain
  • Chronic fatigue
  • Insomnia
  • Hot flashes
  • Irregular menstrual cycle
  • Decreased libido
  • Erectile dysfunction


Due to initial consultation with “doctor google”, patients often perform complete or partial endocrinological evaluation before visiting endocrine clinic. Consultation with endocrinologist may be advised in case of aberration of the following parameters:

  • TSH
  • T4 and/or T3
  • Cortisol
  • ACTH
  • Prolactin
  • Testosterone
  • FSH and/or LH
  • Estradiol and/or progesterone
  • Growth hormone
  • IGF-I (Insulin like growth factor – 1)
  • DHEA-S (Dehidroepiandrosteron sulfat)
  • PTH
  • Insulin
  • Glucose
  • Sodium, potassium or calcium
  • Aldosterone
  • Renin
  • Metanefrine and/or normetanefrine
  • Chromogranin A
  • Calcitonin
  • 5-HIAA (5-hydroxyindoleacetic acid)


One should note that patient’s symptoms or hormone imbalance may not be associated with specific endocrine disorder. They may be caused by chronic stress, dietary habits or medication instead. Therefore, consultation with experienced endocrinologist is crucial at this point, in order to avoid unnecessary, expensive and potentially harmful diagnostic procedures.
