Explore how an endoscopy is performed, detailing each step to provide patients with clarity, reduce anxiety, and support informed decision-making.
An endoscopy is a medical procedure used to examine the digestive tract using a flexible tube with a camera. It helps diagnose and sometimes treat a variety of gastrointestinal conditions. So, how is an endoscopy performed? Understanding the process is important for patients and carers, allowing them to prepare adequately, know what to expect, and feel reassured about the procedure. This guide explains each stage, from preparation through recovery, to ensure a safe and comfortable experience.
Preparing for an endoscopy
- Pre-procedure assessment – Before an endoscopy, a thorough review of medical history, current medications, and allergies is conducted. This ensures the procedure is tailored to each patient’s needs and minimises potential risks.
- Fasting and medication guidance – Patients are generally required to fast for several hours prior to the procedure. Certain medications, such as blood thinners, may need temporary adjustment under medical supervision to ensure safety and optimal results.
- Informed consent – Patients are provided with clear explanations about the procedure, its benefits, and potential risks. How is an endoscopy performed? Understanding this step allows patients to ask questions and give informed consent confidently.
- Anxiety and patient support – Feeling anxious before a procedure is common. Support measures, including discussing sedation options or speaking with nursing staff, help patients feel reassured and comfortable before the endoscopy.
Sedation and comfort
- Types of sedation – Endoscopies are typically performed under light or conscious sedation. The type of sedation used is determined by the procedure and the patient’s preference, ensuring relaxation without compromising safety.
- Monitoring during sedation – Vital signs, including heart rate, blood pressure, and oxygen levels, are continuously monitored. This careful supervision ensures patient safety and allows immediate response to any changes.
- Pain and discomfort management – Local anaesthetic sprays or gels may be applied to minimise discomfort, especially for upper gastrointestinal procedures. These measures help patients remain comfortable throughout the examination.
- Allergies and medical considerations – Patients are asked about any medication or anaesthetic allergies. This information ensures that sedation is administered safely and prevents adverse reactions during the procedure.

How is an endoscopy performed?
- Upper gastrointestinal endoscopy – During an upper GI endoscopy, the flexible tube is inserted through the mouth to inspect the oesophagus, stomach, and small intestine. High-resolution images allow the specialist to detect inflammation, ulcers, or abnormal tissue.
- Colonoscopy – A colonoscopy examines the large intestine via the rectum. It helps identify polyps, inflammation, and early signs of cancer. The procedure allows for immediate intervention if necessary.
- Flexible sigmoidoscopy – This procedure examines the lower part of the colon. It’s often used for targeted diagnostics or screening, providing a less extensive alternative to a full colonoscopy while still delivering valuable insights.
- Specialised interventions – Additional tools can be used during endoscopy to remove polyps, take tissue samples, or treat minor bleeding. These interventions show how an endoscopy is performed for both diagnostic and therapeutic purposes.
Sample collection and therapeutic procedures
- Biopsies – Small tissue samples may be collected for laboratory analysis. Biopsies provide crucial information about infections, inflammation, or abnormal cellular changes, supporting accurate diagnosis.
- Polyp removal – Polyps can be safely removed during the procedure, reducing the risk of future complications or cancer. Early detection and removal are key preventive measures.
- Controlling bleeding – Minor bleeding detected during the procedure can be managed immediately with specialised instruments. Prompt intervention ensures patient safety and reduces post-procedure complications.
- Other minor interventions –Other procedures, such as dilating narrowed areas or applying topical treatments, may also be performed. These therapeutic measures enhance the endoscopy’s diagnostic and treatment capabilities.

Recovery and aftercare
- Immediate recovery and monitoring – Patients are observed until sedation wears off and vital signs stabilise. Mild discomfort, bloating, or soreness may occur but typically resolves within a few hours.
- Dietary and activity guidance – Light meals and gradual resumption of normal activities are advised post-procedure. Specific instructions depend on the type of endoscopy and any interventions performed.
- Managing side effects – Mild side effects are common and usually temporary. Patients are instructed to contact their healthcare provider if symptoms persist or worsen to ensure safe recovery.
- Follow-up and long-term considerations – Results from biopsies or therapeutic interventions may require follow-up. Understanding how an endoscopy is performed helps patients follow guidance and plan any further treatment.
Taking Control of Digestive Health
How is an endoscopy performed? Understanding the steps of the procedure empowers patients to approach the process with confidence and clarity. Expert guidance in endoscopic evaluation ensures that each procedure is conducted safely, results are interpreted accurately, and patients receive tailored advice for digestive health. Timely assessment and intervention help prevent complications, support informed decision-making, and promote long-term gastrointestinal well-being.

FAQs
Is sedation always required for an endoscopy?
Sedation is commonly used to enhance comfort, but some patients may undergo the procedure without sedation, depending on the type and personal preference.
How long does the procedure take?
Most endoscopies are completed within 15 to 30 minutes, though the total appointment may take longer to include preparation and recovery time.
Can I eat or drink after an endoscopy?
Patients are usually advised to start with light meals and liquids once fully recovered from sedation. Specific guidance is provided by the medical team.
Are there any risks associated with endoscopy?
While generally safe, potential risks include mild throat discomfort, bloating, or, rarely, bleeding or infection. Medical staff take precautions to minimise these risks.
Will I know the results immediately?
Some findings can be shared immediately, but biopsy results or detailed analyses may take several days. Follow-up appointments ensure results are explained clearly.
