The endocrine system is made up of a network of glands that release hormones directly into the bloodstream. These hormones regulate many essential body functions, including metabolism, growth, energy levels, and reproduction.

Key glands include:

• Pituitary gland: Often referred to as the “master gland,” it controls the activity of many other hormone-producing glands.
  
  
• Thyroid gland: Located in the neck, it plays a key role in regulating metabolism and energy use.
  
  
• Pancreas: Produces insulin and other hormones to regulate blood sugar levels.
  
  
• Adrenal glands: Produce hormones such as cortisol and adrenaline, which help the body respond to stress and maintain blood pressure.
  
  
• Gonads (ovaries and testes): Produce sex hormones essential for puberty, fertility, and reproductive health.

Endocrinologists are specialist doctors who diagnose and manage conditions related to hormone imbalances and gland dysfunction. These conditions can affect multiple systems in the body and often require ongoing management.

Common conditions include:

• Diabetes mellitus: Conditions affecting insulin production or function, leading to abnormal blood sugar levels.
  
  
• Thyroid disorders: Including hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid).
  
  
• Metabolic bone disease: Such as osteoporosis and calcium disorders.
  
  
• Reproductive and hormonal conditions: Including polycystic ovary syndrome (PCOS), infertility, and menopause-related concerns.
  
  
• Growth disorders: Including growth hormone deficiency and other developmental conditions.
  
  
• Endocrine tumours: Conditions affecting hormone-producing glands such as the thyroid, pituitary, or adrenal glands.
