General Surgery

General Surgery

General surgery can be minimally invasive or open procedures. Specialists who perform these operations have a holistic view of the human body. As a result, these doctors do not just take the helm in the surgery room but also provide preventive care and recovery support.

What Is General Surgery?

General surgery covers operative procedures for a wide range of common ailments. Although general surgeons can perform surgery on almost any part of the body, they typically specialise in injuries and diseases affecting the endocrine system glands (pancreas and thyroid glands), breasts, abdomen, other digestive system organs (intestines, liver and rectum), skin and soft tissues.

General surgeons also diagnose patients and handle patient care before, during and after the operation. Due to their versatility, general surgery specialists often serve in emergency rooms, intensive care units and trauma centres.

Who Performs General Surgeries?

General surgery doctors treat patients through invasive and non-invasive surgeries. Due to their exposure to emergency settings, general surgeons are experts in managing critically ill and injured patients.

General surgeons are knowledgeable about:

  • The structure and functioning of a healthy body
  • How blood flows and clots
  • How wounds heal
  • How the immune system works
  • How infections develop and the role of antibiotics

Why Is General Surgery Important?

The availability of general surgery procedures in private and public health institutions means people living far away from city centres can get crucial emergency care.

During general surgery consultations, surgeons will run exams to analyse your health condition. They may conduct more diagnostic tests and recommend and explain your options and answer your questions.

General surgeons will tell you how long you need to be in the hospital, what to expect during recovery and what you will need once you go home.
