At what age does new onset constipation typically warrant a colonoscopy?

New onset constipation generally warrants further investigation, such as a colonoscopy, starting at age 50. This is largely due to the increased risk of colorectal cancer and other serious gastrointestinal conditions that arise with advancing age. By age 50, many guidelines recommend beginning regular screening for colorectal cancer, which often includes a colonoscopy.

Constipation can be a symptom of underlying pathology, particularly in older adults, where the incidence of colorectal problems increases. Early detection through appropriate screening can significantly impact outcomes, making it crucial to act on new onset symptoms within this age group.

For those younger than 50, while constipation can still be a concern, it is less frequently associated with serious underlying issues compared to people aged 50 and above. Therefore, the threshold for performing a colonoscopy due to new onset constipation is set at age 50 to ensure timely intervention and management of potential health risks.
