Internal medicine deals with the prevention, diagnosis and treatment of diseases of the internal organs and systems. This includes a wide range of conditions that can affect the cardiovascular system, the respiratory system, the gastrointestinal tract, the liver, the kidneys, the endocrine system, the blood and haematopoietic organs, the nervous system and the skin. A key aspect of internal medicine is also working closely with the horse owner to develop a comprehensive understanding of the animal's needs and create customised care, nutrition and management plans. This includes advice on husbandry, feeding and preventative measures to promote the horse's health and well-being.
