Endocrinology is a medical specialty that focuses on the diagnosis and treatment of diseases related to hormones. It specifically deals with the endocrine glands, which are responsible for secreting hormones into the bloodstream. Endocrine diseases are categorized into three main groups: hyposecretion, where the gland produces an insufficient amount of hormones resulting in hormone deficiency; hypersecretion, where the gland is overactive and produces excessive hormones leading to surplus levels of certain hormones; and neoplasia, which refers to the development of tumors in the endocrine glands.

Tumours of endocrine glands can be benign (non-cancerous) or malignant (cancerous) Hormonal imbalances can lead to conditions like Diabetes, Metabolic Disorders of Growth and Puberty, Osteoporosis, Thyroid diseases like Hyperthyroidism or Hypothyroidism, Difficult to Treat Hypertension, Polycystic Ovarian Syndrome (PCOS), Hirsutism, Menopause, Hyperlipidaemia, Hypoglycaemia amongst many others.

Endocrinologists are specially trained physicians who diagnose and treat glandular disorders with the aim of restoring the normal balance of hormones in a patient's body, thereby healing the symptoms.
