What is the most common complication associated with colonoscopy?

Hypoxia is recognized as one of the most common complications associated with colonoscopy procedures. During the procedure, patients often receive sedation, which can suppress their respiratory drive and lead to decreased oxygen levels in the bloodstream. This reduction in oxygen saturation can occur particularly in patients with pre-existing respiratory issues, older individuals, or those receiving higher levels of sedation.

Monitoring vital signs during the procedure is crucial, and healthcare providers are trained to detect early signs of hypoxia. Interventions, such as supplemental oxygen administration or adjusting sedation levels, can mitigate the risk or severity of this complication. Understanding the implications of hypoxia not only highlights the importance of careful patient assessment before and during the procedure but also underscores the significance of proper monitoring to ensure patient safety.
