When Should You Consider a Colonoscopy?

Colonoscopies, like gastroscopies, are performed both for diagnostic purposes in symptomatic individuals and as routine screenings for those without symptoms. One important category of patients includes people who don't experience any symptoms but have reached the age of 45 or older. At this stage of life, it is strongly recommended to undergo a colonoscopy even if you feel perfectly healthy.

Colorectal cancer ranks among the top cancers globally and is the fourth or fifth most common cancer in China. Early detection through colonoscopy can identify precancerous polyps in the colon, which are much easier to treat before they become malignant. Therefore, regardless of family history or current health status, individuals between the ages of 45 and 50 should consider having at least one screening colonoscopy.

If you experience persistent digestive issues such as chronic diarrhea, constipation, or alternating patterns of both, it may be time to consider a colonoscopy. Other warning signs include changes in bowel habits, blood in the stool, or the presence of pus and blood in bowel movements. These symptoms could indicate underlying problems in the colon that require further investigation.

Fortunately, colonoscopy procedures have become increasingly accessible and efficient. In China, the cost of a colonoscopy is significantly lower than in many Western countries, making it an affordable preventive healthcare option. If you're experiencing symptoms, it's advisable to consult with your doctor and follow their recommendation on whether a colonoscopy is necessary. For those without symptoms, scheduling a baseline colonoscopy between the ages of 45 and 50 is a smart step toward long-term health prevention.
