Overview
Surgery is a treatment in which healthcare professionals use instruments and specific techniques to operate on the body. It may be done to diagnose a condition, remove diseased tissue, repair an injury, restore function, or relieve symptoms. Some procedures are done in a clinic or day-surgery center, while others require a hospital stay.
Who Is Affected
People of all ages may need surgery, including newborns, children, adults, and older people. The type of surgery and the risks involved depend on the person's health, age, medical history, and the condition being treated. Pregnant people, older adults, and people with heart, lung, kidney, bleeding, or immune system problems may need extra planning and monitoring.
Prevention
Not all surgery can be prevented, especially when it is needed for injuries, birth conditions, cancer, or emergencies. Some operations may be less likely if underlying health conditions are managed early, screening tests are done when recommended, and injuries are prevented through measures such as seat belt use and workplace safety. Avoiding tobacco and following routine medical care may also lower the chance of some surgical complications.
Diagnosis and Tests
Before surgery, a healthcare professional usually reviews your symptoms, medical history, medicines, allergies, and past operations. You may need blood tests, heart tracing, imaging, or other tests to help plan the procedure and anesthesia. The team also explains what the surgery is for, what to expect, possible risks, and what recovery may involve.
Treatment Categories
Surgery can be elective, urgent, or emergency. It may be done through open surgery, minimally invasive surgery such as laparoscopy or endoscopy, or with robotic or image-guided methods, depending on the condition and available expertise. Care often includes anesthesia, pain control, wound care, infection prevention, and follow-up rehabilitation or therapy if needed.
Living With It
Recovery after surgery varies widely. Some people return to normal activities quickly, while others need weeks or months of healing, rehabilitation, or temporary help with daily tasks. Following discharge instructions, taking medicines only as directed, attending follow-up visits, and reporting new or worsening symptoms are important parts of recovery.
When to Seek Medical Care
Seek medical advice if you have been told you may need surgery, if your symptoms are affecting daily life, or if a condition is not improving with other treatments. After surgery, contact your healthcare team if you have worsening pain, fever, redness or drainage from the wound, trouble eating or drinking, new swelling, or concerns about your recovery. Also ask for guidance if you have questions about returning to work, exercise, driving, or sexual activity.
When It May Be an Emergency
Some conditions need emergency surgery or urgent hospital assessment. Get urgent help for severe bleeding, trouble breathing, chest pain, sudden severe abdominal pain, signs of stroke, major injury, or sudden worsening after an operation such as fainting, confusion, or heavy wound bleeding. Do not delay emergency care if symptoms are severe or rapidly getting worse.
Questions to Ask a Healthcare Professional
You may want to ask why the surgery is recommended, what alternatives exist, and what could happen without it. Ask about the expected benefits, important risks, the type of anesthesia, how to prepare, how long recovery may take, and what support you may need afterward. It can also help to ask who to contact if problems happen after you go home.
