Although complications are possible, they are extremely rare
The pain in throat may linger for another day or two. To relieve the pain, you can take some lozenges for sore throat. Sometimes it is necessary to take a painkiller.
Other possible complications are:
- allergic reaction to the medication which you received during the procedure (local anaesthetic, sedative)
- bleeding in the passage between the oesophagus and stomach, due to bloating (the complication is tackled endoscopically)
- transient occurrence of fever in the afternoon,
- a puncture in the wall by the endoscope, which may require surgery.
In the case the following symptoms ensue after the examination, immediately contact your personal physician or emergency doctor: severe pain in the chest or abdomen, stiff abdomen, blood in vomit or black sticky mud, dizziness, loss of consciousness, fever and/or hypothermia.
