What is a Colonoscopy?
A colonoscopy is a minimally invasive diagnostic procedure that allows a gastroenterologist to examine the inner lining of your colon and rectum. Using a thin, flexible tube called a colonoscope, we can identify abnormalities like polyps, inflammation, or early signs of colorectal cancer.
A colonoscopy is a gold-standard diagnostic procedure that allows a gastroenterologist to examine the entire lining of your colon and rectum using a thin, flexible tube called a colonoscope. Equipped with a high-definition camera and light, the scope transmits real-time images to a monitor, providing a detailed view for the physician. During the 30-to-60-minute procedure, you remain under sedation for maximum comfort. If our team identifies polyps—small growths that are precursors to cancer—we can remove them immediately during the exam, often preventing the development of colorectal cancer entirely. By utilizing advanced irrigation and air-insufflation techniques, we ensure a clear, thorough inspection of the colon wall to identify even the most subtle abnormalities.
Key Benefits
- Cancer Prevention: Removing polyps during the procedure prevents cancer before it starts.
- Early Diagnosis: Detects conditions like Inflammatory Bowel Disease (IBD), Crohn’s, and ulcerative colitis early.
- Symptom Relief: Provides answers for unexplained abdominal pain, rectal bleeding, or persistent changes in bowel habits.
Screening vs. Diagnostic Colonoscopy
Screening colonoscopy checks for colorectal cancer and precancerous polyps in people without symptoms.
Diagnostic colonoscopy looks for the cause of symptoms or follows up an abnormal stool test or earlier findings.

When Should You Schedule a Screening?
Routine screenings are critical. According to current medical guidelines, the U.S. Preventive Services Task Force recommends screening for adults ages 45 to 75 who are at average risk.1
Average risk
Adults should begin screening at age 45. Screening is recommended through age 75; decisions for ages 76 to 85 are made individually.
Higher risk
If you have a family history of colorectal cancer or specific gene mutations, you may need to start earlier (often 10 years before the earliest age of onset in your family).
Symptoms
If you notice blood in your stool, persistent belly pain, or unexplained weight loss, do not wait—schedule an urgent evaluation.
From persistent abdominal pain and rectal bleeding to changes in bowel habits, our Cypress GI clinic provides advanced evaluation and individualized treatment for a wide range of digestive concerns.
Increased or High Colorectal Cancer Risk
You may need to begin screening earlier, undergo screening more frequently, or use a specific screening method when you have:
Screening recommendations for higher-risk patients are more individualized and should be determined by a qualified healthcare professional.
Risk factors that may change your screening plan
- A parent, sibling, or child with colorectal cancer or advanced polyps
- A personal history of colon polyps or colorectal cancer
- Crohn’s disease or ulcerative colitis affecting the colon
- Lynch syndrome, familial adenomatous polyposis, or another hereditary cancer syndrome
- Previous radiation treatment involving the abdomen or pelvis
- A previous abnormal colorectal cancer screening result
Screening recommendations for higher-risk patients should be determined by a qualified healthcare professional.
Due for a Colonoscopy?
Adults at average risk should begin colorectal cancer screening at age 45. Dr. Khan performs screening and diagnostic colonoscopy for Cypress-area patients.
Symptoms or Abnormal Test Results
Following a clinical evaluation, a diagnostic colonoscopy may be considered for concerns such as:
Colonoscopy can help investigate bleeding, changes in bowel movements, abdominal pain, and unexplained weight loss. Gastrointestinal evaluation may also be recommended for certain patients with iron-deficiency anemia.
Our gastroenterology center in Cypress helps patients find answers for bloating, chronic stomach pain, acid reflux, blood in the stool, IBS, and other persistent digestive issues.
When to seek emergency care
Call 911 or go to the nearest emergency room for heavy rectal bleeding, black or tarry stools with dizziness or fainting, vomiting blood, or severe abdominal pain.
Reasons a diagnostic colonoscopy may be considered
- Rectal bleeding or blood in the stool
- Persistent or unexplained changes in bowel habits
- Ongoing diarrhea
- Unexplained abdominal pain
- Unintentional weight loss
- A positive FIT, stool DNA, or other colorectal screening test
- Unexplained iron-deficiency anemia
- Monitoring of inflammatory bowel disease
- Follow-up of previous polyps or abnormal findings
A symptom alone does not confirm a diagnosis. Symptoms should be evaluated by a qualified medical professional.
Conditions We Diagnose and Treat with Colonoscopy
A colonoscopy can find, and often treat, several conditions of the colon and rectum during the same procedure.
Colorectal Cancer
Early detection and prevention by removing polyps before they become cancerous.
Polyps
Non-cancerous growths that can develop into cancer if left untreated.
Inflammatory Bowel Disease (IBD)
Diagnosing and monitoring conditions like Crohn’s disease and ulcerative colitis.
Diverticulosis
Detecting pockets in the colon that can lead to complications.
Unexplained Digestive Symptoms
Investigating causes of chronic abdominal pain, rectal bleeding, diarrhea, or constipation.
Iron-Deficiency Anemia
Looking for a source of slow or hidden bleeding in the colon when blood tests show iron-deficiency anemia.
What to Expect: Your Guide to the Procedure
We believe transparency reduces anxiety. Here is what your experience will look like:
Preparation
Your results depend on a clear colon. The office provides detailed, easy-to-follow prep instructions, including dietary guidelines and a bowel cleansing solution, and answers your questions before the procedure.
The Procedure
The exam typically takes 30 to 60 minutes. You will be under sedation, ensuring you remain comfortable and pain-free throughout the process.
Recovery
You will rest in our recovery area for about an hour until the sedative wears off. Because of the sedation, you will need to arrange for a driver to take you home. Most patients return to their normal routine the very next day.
Our Commitment to Quality and Patient Safety
Colonoscopy quality depends on a well-prepared colon, a careful and complete examination, and safe sedation with monitoring. Gastroenterology societies track quality measures such as the adenoma detection rate (how often precancerous polyps are found), the quality of bowel preparation, and the time spent examining the colon.
At United Gastroenterology Associates, safety starts with evidence-based bowel preparation instructions so the colon can be seen clearly. During the procedure, your vital signs are monitored while you are sedated, and Dr. Khan performs a careful examination of the colon lining. Patients are welcome to ask about preparation, sedation, and quality measures during the consultation.

How long does a colonoscopy take?
The exam typically takes 30 to 60 minutes, and most patients rest for about an hour afterward while the sedation wears off.
How do I prepare for a colonoscopy?
Preparation includes a special diet the day before and a bowel cleansing solution. The office gives you written instructions for your prescribed prep. View colonoscopy prep guides.

No. Because of the sedation, you need an adult to drive you home. Most patients return to normal activities the next day.
What happens if a polyp is found?
Most polyps can be removed during the same colonoscopy and sent for testing. Dr. Khan reviews the results with you and recommends when your next colonoscopy should be.

Costs vary based on your insurance coverage. Our billing team is here to help you understand your out-of-pocket costs and insurance benefits. Self-pay colonoscopy options are also available.
