“I Thought It Would Be Quick, But Then Everything Went Wrong”: Real Stories About Colonoscopy Complications
When 42-year-old Lisa Thompson went in for her first colonoscopy, she expected a routine check — maybe some mild discomfort and then home in a few hours. Instead, she left the clinic feeling dizzy, cramping, and panicked about what was happening.
“I knew there could be some bloating or gas,” Lisa says. “But when I started bleeding more than I expected, I freaked out. I didn’t know if it was normal or if I should call someone.”
Lisa’s story isn’t unique. While most colonoscopies go smoothly, a small number of patients experience complications — sometimes during the procedure, sometimes days later. For web magazine readers, the key isn’t just the statistics, it’s the human experience.
When Problems Usually Appear
Take Jamal Rodriguez, 58, a schoolteacher from Texas. His colonoscopy went perfectly, but two days later, he noticed sharp abdominal pain and mild bleeding.
“I wasn’t sure if it was something serious,” Jamal recalls. “I kept thinking, ‘Am I overreacting?’ but my gut told me to call the doctor.”
According to Dr. Emily Harper, gastroenterologist, complications like bleeding or perforation are rare but do happen, often within 24–48 hours. “Patients sometimes wait too long to call. Any heavy bleeding, severe pain, or fever is a reason to contact your healthcare provider immediately,” she says.
Who’s at Risk
Not everyone is equally at risk. Older adults, people on blood thinners, or those with existing health conditions like heart or lung disease are more likely to experience complications.
Mark, 67, who had a polyp removed during his colonoscopy, says, “I knew my age and meds made me a bit riskier. The doctor explained everything, but honestly, nothing prepares you for the anxiety when you’re home and waiting to see if everything’s fine.”
Who Might Avoid Colonoscopy
Some people might be advised to skip a colonoscopy or wait for an alternative screening. Sarah, 35, has a severe allergy to sedation medications. Her doctor recommended CT colonography instead. “I was disappointed I couldn’t do the normal procedure, but I’d rather be safe,” she says.
Managing Complications: Real Advice from Patients
For Lisa, Jamal, and others, the first step after any unusual symptom is to call your doctor immediately. Lisa emphasizes the emotional side: “Even if the problem is minor, it’s terrifying. Having someone explain what’s normal and what isn’t really helps.”
Jamal learned to monitor himself closely for two weeks after the procedure, especially after polyp removal. “It’s about trusting your instincts, but also not panicking over every little twinge,” he explains.
The Bottom Line
Colonoscopy complications are rare, but real. What matters is knowing when to worry, who’s at risk, and having a plan for managing problems. These stories show that human experiences — fear, relief, confusion — are just as important as medical facts.
