Human: My doctor wants me to get a colonoscopy, but I'm worried about the risks. What are the risks? Assistant: 
The most common risk associated with a colonoscopy is a small perforation of the colon wall. This can cause minor pain and discomfort, which usually resolves within a few days. Other potential complications include bleeding, infection, and allergic reaction to the sedative used during the procedure. In rare cases, there may be more serious consequences such as an abdominal abscess or even death. It is important to discuss these risks with your doctor before making any decisions about whether to undergo a colonoscopy.
