A gastroscopy may be necessary to ascertain the cause of persistent upper abdominal symptoms. These may include recurrent pain, long-lasting nausea with or without vomiting, frequent heartburn, and swallowing difficulties.
Gastroscopy in Düsseldorf
Gastroscopy entails examination of the oesophagus, the stomach, and the upper part of the small intestine with a flexible instrument called an endoscope.
No solid food should be eaten after 20:00 on the day before the gastroscopy. Drinking is allowed until 24:00. No food or drink should be consumed on the morning of the examination.
Immediately before the gastroscopy, the patient can choose to receive a sedative or an injection of short-acting general anaesthetic and will then not feel the examination at all.
After the gastroscopy, a patient who opted for sedation or anaesthesia must be accompanied by someone else on the journey home. The law does not permit a sedated patient to leave the practice alone.
After a gastroscopy has been carried out under sedation or short-term anaesthesia, although the patient will usually be fully awake and mobile 10–15 minutes later and is then allowed to leave the practice (together with another person), he/she should under no circumstances drive a motor vehicle for the rest of the day and is advised not to go to work.
