The endocrine system is a complex group of glands that together with the nervous system controls our bodies. However, the endocrine system uses hormones to stimulate the metabolic activities of the cells.

Endocrine glands are organs that make hormones. These are chemicals that help to control activities in your body. Hormones control reproduction, metabolism (food burning and waste elimination), and growth and development. Hormones also control the way we respond to our surroundings, and they help to provide the proper amount of energy and nutrition our bodies needs to function.

The endocrine glands include the thyroid, parathyroid, pancreas, ovaries, testes, adrenal, pituitary and hypothalamus and there are some in the intestines.

Often these conditions are complex and involve many body systems – for example hormones can affect our musculoskeletal system, nervous system, lymphatic system, cardiovascular system, endocrine system, immune systems and/or others.

Conditions we treat

Endocrinologists are trained to diagnose and treat hormone problems by helping to restore the normal balance of hormones in your system. They take care of many conditions including:

  • Thyroid diseases such as Hyperthyroidism (thyrotoxicosis), Hyperthyroidism, Goitre (Enlarged thyroid gland), Thyroid cancers (papillary, follicular, medullary, anaplastic thyroid cancers), Graves’s disease (thyroid eye disease), Hashimoto’s thyroiditis etc
  • Metabolic disorders such as Metabolic syndrome, Insulin resistance, Obesity
  • Pituitary conditions such as prolactinoma, hypopituitarism, pituitary Cushing’s, acromegaly, pituitary apoplexy, pituitary adenoma and diabetes insipidus
  • Sex and fertility such as Hypogonadism, polycystic ovarian syndrome, infertility and ovarian failure, Kallman syndrome
  • Parathyroid, calcium and bone conditions such as hypercalcaemia, hypocalcaemia, osteoporosis, osteopenia.
  • Conditions of the adrenal gland such as Adrenal Cushing’s syndrome, Conn’s syndrome, Addison’s disease, adrenal insufficiency, adrenocortical adenomas and carcinomas, congenital adrenal hyperplasia, phaeochromocytoma
