When to Get a Colonoscopy: Age, Risk Factors, and Timing

When to get a colonoscopy

Wondering when to get a colonoscopy? For most adults at average risk, screening should begin at age 45. But if you have certain symptoms, a family history of colorectal cancer, or another digestive condition, your doctor may recommend screening even sooner.

Getting screened at the right time can lower your risk of colorectal cancer. Colonoscopies can find polyps before they become cancer. They can also help doctors diagnose several digestive conditions. If you’re due for screening or have concerning symptoms, a gastroenterologist in San Antonio can help you decide when it’s time for your first or next colonoscopy.

When Should You Get a Colonoscopy?

Most adults at average risk should get their first colonoscopy at age 45.

If your results are normal and you don’t have additional risk factors, you’ll usually need another colonoscopy every 10 years until age 75. Between ages 76 and 85, your doctor will decide if you should continue screening based on your health and past results. Routine screening is generally not recommended after age 85.

Some people should begin screening before age 45. Your doctor may recommend an earlier colonoscopy if you have:

  • A parent, sibling, or child with colorectal cancer or colon polyps
  • Crohn’s disease or ulcerative colitis
  • A personal history of colon polyps or colorectal cancer
  • Certain inherited conditions that increase colon cancer risk
  • Previous radiation treatment to the abdomen or pelvis

Signs You May Need a Colonoscopy Sooner

A colonoscopy isn’t only used for routine screening. Your doctor may also recommend one if you have symptoms that need to be checked.

These symptoms include:

  • Blood in your stool
  • Ongoing diarrhea or constipation
  • A lasting change in your bowel habits
  • Persistent abdominal pain
  • Unexplained weight loss
  • Iron-deficiency anemia
  • Ongoing fatigue without a clear cause

These symptoms don’t always mean something serious, but they shouldn’t be ignored.

What Is a Colonoscopy?

A colonoscopy lets your doctor examine the inside of your large intestine, also called the colon. During the procedure, a thin, flexible tube with a small camera is inserted through the rectum. The camera lets your doctor check for inflammation, bleeding, polyps, and other changes.

If your doctor finds a polyp during the procedure, they can often remove it right away. Removing polyps can help prevent colorectal cancer because some may become cancerous over time.

What Can a Colonoscopy Detect?

A colonoscopy can help diagnose or detect several conditions, including:

Finding problems early often makes treatment easier.

What Happens During a Colonoscopy?

Before the procedure, you’ll need to follow instructions to clean out your colon. This helps your doctor clearly see the lining of your intestine.

Most people receive medication to keep them comfortable and sleepy during the exam. Your doctor will recommend the type of sedation that’s best for your health.

The procedure usually takes about 30 minutes. It may take a little longer if your doctor removes polyps or collects tissue samples.

Because of the sedation, you’ll need someone to drive you home afterward. Most people return to their normal activities the following day.

When to Get a Colonoscopy in San Antonio

Getting a colonoscopy at the right time is one of the best ways to protect your digestive health. For most adults, screening begins at age 45, but some people should start earlier because of their family history, medical conditions, or symptoms.

Routine screening can find colorectal cancer early and remove precancerous polyps before they become cancer. If you’re due for screening or have symptoms that concern you, don’t wait to talk with your doctor.
