Rooted in the innovations of upper endoscopy, colonoscopy emerged in the 1960s as a powerful tool that helps doctors keep your colon and rectal health in check. The numbers are backing this up. With nearly 15 million colonoscopies performed annually in the United States alone, the overall risk of colorectal cancer death may be reduced by 60%.
What makes this procedure so valuable is its ability to catch different issues at various points in life. From young adults to seniors, a colonoscopy can detect mild to serious conditions that allow you to act promptly. That’s what this article is all about. So, read on to know what a colonoscopy can detect according to your age bracket.
Young Adults (Under 45)
For most people under 45, a colonoscopy isn’t part of routine checkups. That’s because serious conditions like colorectal cancer are rare in this age group. But if you’re a young adult with symptoms like ongoing belly pain, blood in your stool, or changes in your bowel habits, your doctor might recommend a colonoscopy to figure out what’s going on.
In countries like Singapore, where advanced medical care is widely available, a colonoscopy Singapore can quickly provide answers for young adults who are experiencing these warning signs.
So, what might a colonoscopy identify in teenagers and young adults?
A common finding is Inflammatory Bowel Disease (IBD), including Crohn’s disease or ulcerative colitis. These diseases cause inflammation or ulcers in the colon that may hurt or bleed. They typically occur in teenagers or young adults, and a colonoscopy can diagnose them, so treatment can start early.
The other thing at risk is polyps, or colon polyps. Alarms aren’t sounded during this age bracket, though, because the majority are harmless. But that doesn’t mean the chances of them developing into cancer later are zero.
While polyps are uncommon among young adults, they’re more likely to occur if you have a family history of polyps or inherited disorders like Lynch syndrome or familial adenomatous polyposis. A colon cancer screening can identify these polyps and allow the physician to intervene in time.
Some of the other issues a colonoscopy might reveal are hemorrhoids or anal fissures, both of which can cause bleeding. But they’re usually not hard to treat. On extremely rare occasions, a colonoscopy might reveal early-stage colorectal cancer, which is more common in 20% of adults under the age of 50 years.
In summary, for young adults, a colonoscopy is a screening examination. But approaching middle age, the role of colonoscopy shifts.
Middle Age (45 to 65)
Once you reach 45, a colonoscopy becomes a key component of keeping your health at its best. Even when you are healthy, it’s still important. The reason for this is that the risk of cancer of the colorectal area shoots up in the 40s and 50s.
Experts from the American Cancer Society recommend that people with average risk have their initial screening colonoscopy at 45 years. If everything is normal when you have your test, you might only need to have one every 10 years. But if you have risk factors, you might need to begin earlier or have more frequent tests.
The primary focus of colonoscopy for this age group is on colorectal polyps because these become more common as you age. Some of them, like an adenomatous polyp, could be cancerous if they are not removed.
In its initial development, colorectal cancer can be asymptomatic, hence the need for screening. If cancer has further developed, a colonoscopy can identify tumors that might be causing bleeding, pain, or changes in bowel habits.
Other than cancer, a colonoscopy can also identify diverticulosis or diverticulitis, which are more common in middle age. Diverticulosis is when there are pouches in the wall of the colon. When these become infected or inflamed, it becomes diverticulitis, which can be painful and bleed.
For individuals with IBD diagnosed in earlier years, a colonoscopy at this time is for disease monitoring. Chronic IBD can raise the risk of colon cancer, so regular checks are necessary.
Older Adults (Over 65)
For people over the age of 65, colonoscopies are still essential, but the approach depends on your overall health. If you’re healthy and active, continuing screening or follow-up colonoscopies is ideal. This is especially true if you’ve had polyps or other issues in the past.
But if you have severe health issues or a reduced life expectancy, your physician may recommend other exams, such as stool tests, because the potential for complications of sedation can outweigh the benefits.
Colorectal cancer and polyps are the most prominent concerns at this period in life because cancer risk increases the most at this age range. Physicians could identify tumors or growths that may be accountable for signs and symptoms such as weight loss, anemia, or alteration of bowel habits. The removal of polyps or the detection of cancer, even later in life, can nonetheless make a gigantic difference.
Diverticular disease, as mentioned above, is also a frequent finding. With age, those pouches in the colon wall are more likely to bleed. A colonoscopy can detect these conditions and direct treatment.
Likewise, ischemic colitis—a condition due to decreased blood flow to the colon—is more prevalent in older persons with heart or vascular disease, and a colonoscopy can diagnose it.
Other conditions include angiodysplasia, in which blood vessels of the colon weaken and bleed. Strictures, narrowed sections in the colon due to scarring or tumors, are also an option. On occasion, a colonoscopy may detect late-onset IBD or microscopic colitis, which result in diarrhea and may need certain therapies.
Wrapping It Up
As with any health condition, prevention is always better than cure. That’s what a colonoscopy promises. By catching and clarifying the symptoms early on, doctors can choose the right treatment plan for you. So, if you’re wondering whether you need a colonoscopy, you can start a conversation with your doctor.
