Following a colonoscopy, it is important to contact your doctor immediately if you experience any of the following symptoms:
* Fever or chills
* Persistent dizziness and nausea
* Inability to pass gas or stool
* Blood in your stool
* Chest pain or heart palpitations
* Multiple or significant rectal bleeding episodes
* Severe abdominal pain or bloating

These symptoms, especially severe abdominal pain, fever, chills, nausea, and vomiting, could be indicative of serious complications such as colon perforation.
