Colonoscopy in Houston: Expert Care for Comprehensive Colorectal Screening

By Dr. Ritha Belizaire

Quick Insights

A colonoscopy is a procedure where a doctor uses a flexible camera to examine the inside of your colon (large intestine) to find and remove growths or detect cancer early. It plays a vital role in preventing colorectal cancer and is recommended even if you feel healthy, as early changes often have no symptoms.

Here's why this matters: According to leading research, colorectal screening with colonoscopy can reduce colorectal cancer deaths by up to 40% over ten years.

Key Takeaways

• Colonoscopy helps find and remove polyps (small growths) before they become cancerous.
• Proper preparation, like bowel cleansing, is crucial for effective and accurate results.
• Colonoscopy is considered safer and more effective than many other screening tests.
• Early colorectal screening significantly lowers your risk of developing or dying from colorectal cancer.

Why It Matters

Getting a colonoscopy can relieve anxiety about what's happening in your body. It helps you avoid painful symptoms or emergency surgery later. Most importantly, it empowers you to take charge of your long-term health.

Understanding the process makes it easier to overcome fear and prioritize your well-being—especially when expert, compassionate care is available every step of the way.

Introduction

As a board-certified colorectal surgeon serving Houston, I know the word "colonoscopy" can spark both curiosity and a bit of dread.

Let me explain what it really is. This procedure uses a thin, flexible camera to examine your colon's lining, searching for polyps or early signs of cancer. It's the gold standard for detection, catching silent changes before they become serious—often long before you'd notice any symptoms. At Houston Community Surgical, where busy schedules and health anxieties can make screening easy to delay, understanding what a colonoscopy is and why it matters can make all the difference.

Here's what the research shows: Screening with colonoscopy can reduce your risk of dying from colorectal cancer by up to 40% over ten years, according to recent clinical trials from UCSD. That's not just a statistic—it's a second chance for thousands of families.

If you've been putting this off, you're not alone. Let's take a closer look at how this simple step can protect your health and peace of mind.

Understanding the Procedure: What to Expect

A colonoscopy (a procedure using a thin, flexible camera to examine the colon) is the gold standard for finding and removing polyps (small growths) and detecting early signs of colorectal cancer.

During the procedure, I guide a slender tube with a camera through your rectum and colon, carefully inspecting the lining for anything unusual. If I spot a polyp, I can remove it right then and there—often before it ever has a chance to cause trouble.

How Colonoscopy Detects Cancer and Polyps

Colonoscopy allows me to see the entire length of your colon. This means I can find even tiny polyps or early cancers that other tests might miss.

Removing these polyps during the procedure is one of the most effective ways to prevent colorectal cancer. In my experience serving Houston-area residents, catching these changes early makes a world of difference for your long-term health.

According to research, colonoscopy is recognized for its high efficacy and low complication rate, making it the reference standard for colorectal screening in the medical community.

Why Is Colorectal Screening Important?

Colorectal screening is essential because colorectal cancer often develops silently, without symptoms, until it's advanced.

By the time you notice changes like bleeding or abdominal pain, the disease may already be more difficult to treat. That's why I recommend colorectal screening even if you feel perfectly healthy.

Here's what the numbers tell us: Screening with colonoscopy can reduce your risk of developing colorectal cancer and lower your chances of dying from it. A large population study found that people who underwent colonoscopy for colorectal screening had a 10-year colorectal cancer risk of just 0.98%, compared to 1.20% for those who skipped screening.  That's a small number, but it represents thousands of lives saved.

In my practice at Houston Community Surgical, I've seen how early detection not only saves lives but also spares people from more invasive treatments down the road. Colorectal screening is a simple step that can protect your health and your peace of mind.

Who Should Get a Colonoscopy in Houston?

If you're 45 or older, or have a family history of colorectal cancer or polyps, it's time to talk about colorectal screening.

Guidelines now recommend starting at age 45 for most people, but you may need to start earlier if you have certain risk factors.

Screening Guidelines by Age and Risk

• Average risk: Start at age 45 and repeat every 10 years if results are normal.
• Increased risk: If you have a family history, personal history of polyps, or certain genetic conditions, you may need to start earlier and screen more often.
• Symptoms: If you notice rectal bleeding, unexplained weight loss, or persistent changes in bowel habits, don't wait—schedule a colonoscopy right away.

According to expert guidelines, colonoscopy should be performed within 12 months for anyone with a positive non-endoscopic screening test or concerning symptoms.

In my experience, acting quickly when symptoms appear can make all the difference.

Special Considerations for Houston Residents

Living in Houston means you have access to rapid appointments and advanced care.

Houston is home to respected medical centers like Texas Medical Center, reflecting the city's leadership in healthcare. I offer same-day or next-day scheduling for urgent cases, and virtual second opinions for those who need extra reassurance before coming in.

When to Seek Medical Attention

If you experience rectal bleeding, sudden unexplained weight loss, or severe abdominal pain, contact a physician immediately. These symptoms may signal a serious condition that needs prompt evaluation.

Benefits and Risks: What the Research Shows

Colonoscopy offers powerful benefits: it can find and remove precancerous polyps, detect cancer early, and reduce your risk of dying from colorectal cancer.

In my years as a colorectal surgeon, I've seen firsthand how this procedure changes lives for the better.

Research confirms that colonoscopy is the reference standard for colorectal screening, with high efficacy and a low complication rate.  A study of over 84,000 people found that the 10-year risk of colorectal cancer was significantly lower for those who had a colonoscopy.

The quality of your colonoscopy also matters—higher detection rates by well-trained physicians are linked to lower risk of interval cancers.

Colonoscopy vs. FIT and Capsule Endoscopy

While stool-based tests like FIT (fecal immunochemical test) and colon capsule endoscopy are less invasive, they don't allow for immediate removal of polyps.

Colonoscopy remains the only test that lets me find and treat problems in one visit. However, for some people, alternatives may be appropriate—especially if you're unable or unwilling to undergo a colonoscopy.

Understanding Complications and Safety

Colonoscopy is generally very safe, but like any procedure, it carries small risks such as bleeding or perforation.

These complications are rare, especially when performed by experienced physicians using modern equipment. Gut Medical Journal 2025 I always discuss these risks with you beforehand and take every precaution to keep you safe.

How to Prepare for a Colonoscopy

Preparation is key to a successful colonoscopy. A clean colon allows me to see every detail and catch even the smallest polyps.

Inadequate prep can mean missed findings or the need to repeat the procedure.

Here's how to get ready:

• Follow the specific diet instructions I provide (usually clear liquids the day before).
• Take the prescribed bowel prep solution exactly as directed.
• Arrange for someone to drive you home after the procedure.

Research shows that adequate bowel preparation is critical for effective colorectal screening and reduces the chance of missing important findings. Guidance and support can also help reduce anxiety and improve participation rates.

I always encourage you to reach out with questions—no concern is too small.

Optimizing Bowel Preparation

• Start your prep early in the evening before your procedure.
• Drink plenty of clear fluids to stay hydrated.
• Avoid red or purple liquids, which can look like blood during the exam.

Tips for Reducing Procedure Anxiety

• Ask me any questions you have ahead of time—I'm here to help.
• Bring a friend or family member for support.
• Remember, sedation will keep you comfortable during the procedure.

In my practice, I've found that a little reassurance and clear instructions go a long way in making the process less stressful.

What to Expect During and After the Procedure

On the day of your colonoscopy, you'll check in, change into a gown, and meet with me to review the plan. I'll answer any last-minute questions and make sure you're comfortable.

Sedation and Comfort Measures

You'll receive sedation to help you relax and stay comfortable. Most people remember little or nothing of the procedure itself.

I use the latest comfort measures—including gentle technique and, when appropriate, nitrous oxide for in-office treatments—to make the experience as easy as possible.

Recovery and Results Timeline

After the procedure, you'll rest in a recovery area until the sedation wears off. You can usually go home within an hour or two.

I'll review the findings with you and let you know when to expect biopsy results, if any were taken. Most people feel back to normal by the next day.

In my experience, patients are often surprised by how quick and painless the process is. My goal is to make sure you feel informed, respected, and cared for every step of the way.

Alternatives to Colonoscopy: What Are the Options?

If you're unable or unwilling to have a colonoscopy, there are other colorectal screening options.

These include:

• FIT (Fecal Immunochemical Test): A stool test you do at home, repeated annually.
• Cologuard (stool DNA test): Checks for abnormal DNA and blood in your stool.
• CT Colonography (virtual colonoscopy): Uses imaging to look for polyps.
• Colon Capsule Endoscopy: You swallow a tiny camera that takes pictures as it passes through your colon.

Recent research shows that the detection rate of advanced neoplasia is similar between colon capsule endoscopy and colonoscopy, but only colonoscopy allows for immediate removal of polyps.

I help you choose the best option based on your health, preferences, and risk factors.
