Colonoscopy

At Yas Healthcare’s Digestive Disease Clinic, we provide advanced colonoscopy screening and diagnostic procedures to detect and prevent colon cancer and other gastrointestinal conditions.

A colonoscopy is a medical procedure used to examine the inner lining of the colon (large intestine) and rectum using a thin flexible tube with a small camera called a colonoscope. This procedure helps doctors identify polyps, inflammation, bleeding, or early signs of colorectal cancer.

Because colonoscopy allows doctors to detect and remove precancerous polyps during the same procedure, it is considered the most effective test for colon cancer screening.


What Is Colon Cancer Screening?

Colon cancer screening is performed to detect cancer or precancerous growths before symptoms appear. Early detection significantly increases the chances of successful treatment and prevention.

Polyps are small growths in the colon that may develop into colorectal cancer over time. During a colonoscopy, these polyps can be safely removed, reducing the risk of cancer.


When Should You Have a Colonoscopy?

Most medical guidelines recommend that adults begin colon cancer screening at age 50 if they have an average risk of developing the disease.

However, screening may begin earlier (around age 40 or younger) if you have:

  • A family history of colon cancer

  • A history of colon polyps

  • Certain digestive diseases

  • Genetic conditions that increase colon cancer risk

Your gastroenterologist will recommend the best screening schedule based on your medical history.


Why Might Your Doctor Recommend a Colonoscopy?

Your doctor may recommend a colonoscopy if you experience symptoms such as:

  • Blood in the stool

  • Changes in bowel habits

  • Unexplained anemia

  • Persistent abdominal pain

  • Abnormal results from another colon test

  • A history of colon polyps or colorectal cancer

A colonoscopy helps doctors diagnose digestive conditions and determine the most appropriate treatment plan.


Preparing for a Colonoscopy

Proper preparation is essential to ensure accurate results.

Before the procedure, your doctor will provide instructions that may include:

  • Following a special low-fiber diet

  • Drinking a bowel preparation solution to clean the colon

  • Temporarily stopping certain medications

The bowel preparation causes temporary watery diarrhea, which clears the colon so the doctor can see the intestinal lining clearly.


What Happens During a Colonoscopy?

During the colonoscopy procedure:

  1. You will receive medication to help you relax and remain comfortable.

  2. A thin flexible colonoscope is gently inserted into the rectum and advanced through the colon.

  3. The camera transmits images to a monitor so the doctor can examine the colon.

If needed, the doctor may:

  • Remove polyps

  • Take a biopsy (tissue sample) for laboratory testing

These procedures are painless because the colon has few pain-sensitive nerve endings.


Recovery After a Colonoscopy

After the procedure:

  • You can usually resume eating normally

  • You should avoid driving or returning to work for the rest of the day

  • Your doctor will advise when to restart any medications

Most patients recover quickly and can return to normal activities the following day.


When Should You Contact Your Doctor?

Although complications are rare, contact your doctor immediately if you experience:

  • Severe abdominal pain

  • Persistent vomiting

  • Fever

  • A hard or swollen abdomen

  • Heavy bleeding from the rectum

Upper endoscopy

Upper Endoscopy (Gastroscopy) | Digestive System Examination

Digestive Disease Clinic – Yas Healthcare

An upper endoscopy, also known as gastroscopy, is a diagnostic procedure used to examine the upper digestive tract, including the esophagus, stomach, and duodenum (the first part of the small intestine).

During the procedure, a doctor uses a thin flexible tube with a small camera and light (endoscope) to view the lining of the digestive tract. Upper endoscopy helps diagnose and treat conditions affecting the digestive system, including acid reflux, ulcers, inflammation, bleeding, and abnormal growths.

At Yas Healthcare’s Digestive Disease Clinic, upper endoscopy procedures are performed using advanced endoscopic technology and expert gastroenterology care.


Why Might You Need an Upper Endoscopy?

Your doctor may recommend an upper endoscopy test if you experience symptoms such as:

  • Persistent upper abdominal pain

  • Acid reflux (GERD) or heartburn

  • Long-lasting nausea or vomiting

  • Chronic diarrhea

  • Black stools or blood in vomit

  • Difficulty swallowing or food getting stuck in the throat

  • Abnormal results from other digestive tests

  • A swallowed foreign object

  • Follow-up evaluation of ulcers or growths in the digestive tract

Upper endoscopy helps doctors identify the cause of these symptoms and determine the most appropriate treatment.


Preparing for an Upper Endoscopy

Your doctor will provide instructions to help prepare for the procedure. Preparation may include:

  • Stopping food and drinks for several hours before the test

  • Temporarily stopping certain medications

  • Following any additional instructions given by your doctor

It is important to carefully follow preparation guidelines to ensure the procedure is accurate and safe.


What Happens During an Upper Endoscopy?

During the procedure:

  1. An IV line will be placed in your arm or hand.

  2. Medication will be given to help you relax and feel comfortable.

  3. Your doctor may use a numbing spray to reduce throat discomfort.

  4. A small mouth guard is placed to protect your teeth.

The doctor then gently passes the endoscope through the mouth and into the esophagus, stomach, and duodenum to examine the lining of the digestive tract.

During the exam, your doctor may also:

  • Perform a biopsy (take a small tissue sample for laboratory testing)

  • Stop bleeding

  • Remove growths

  • Treat narrowing of the esophagus that may cause swallowing difficulties

Most patients do not feel pain during the procedure.


Recovery After an Upper Endoscopy

After the procedure, you will remain under observation for 1–2 hours while the sedative medications wear off.

Most patients:

  • Should not drive or return to work on the same day

  • Can usually resume normal activities the following day

  • Can eat normally after the procedure unless advised otherwise by the doctor

Your doctor will provide instructions regarding medications and follow-up care.


Possible Side Effects

Upper endoscopy is generally a safe procedure, but mild side effects can occur.

The most common effects include:

  • Bloating

  • Mild throat discomfort

  • Temporary nausea due to sedation

Rare complications may include:

  • Bleeding (especially if a growth is removed)

  • Infection

  • Tear in the digestive tract lining

  • Irritation around the IV site

Your doctor will discuss any potential risks before the procedure.


When Should You Contact Your Doctor?

Contact your doctor immediately if you experience any of the following symptoms after an upper endoscopy:

  • Severe abdominal pain

  • Persistent vomiting

  • Fever

  • Difficulty swallowing or severe throat pain

  • Black stools

  • A swollen or hard abdomen

Sigmoidoscopy

Flexible Sigmoidoscopy | Colon Examination

Digestive Disease Clinic – Yas Healthcare

A flexible sigmoidoscopy is a diagnostic procedure used to examine the lower part of the large intestine (colon), including the rectum and sigmoid colon. The procedure is performed by a trained endoscopist, a doctor specialized in gastrointestinal endoscopic procedures.

Flexible sigmoidoscopy is commonly used to detect colon polyps, inflammation, or early signs of colon cancer, especially in adults over the age of 50 as part of routine colon cancer screening.

In some cases, a colonoscopy, which examines the entire large intestine, may be recommended depending on the patient’s symptoms or medical history.


Why Is a Sigmoidoscopy Performed?

Your doctor may recommend a flexible sigmoidoscopy for several reasons, including:

  • Colon cancer screening

  • Detection of colon polyps

  • Blood in the stool or rectal bleeding

  • Persistent diarrhea

  • Evaluation of inflammation of the colon (colitis)

  • Follow-up after pelvic radiation therapy

  • Examination of the colon alongside other tests such as barium enema studies

This procedure helps doctors diagnose digestive conditions and guide appropriate treatment.


Preparing for a Sigmoidoscopy

Proper preparation is necessary to ensure that the lower colon is clean and clearly visible during the examination.

Your healthcare provider will give detailed instructions that may include:

  • Following a clear liquid diet

  • Taking laxatives

  • Using an enema before the procedure

These steps help clear the colon so the doctor can obtain the most accurate view of the intestinal lining.


Medication Instructions

Some medications may need to be temporarily stopped before the procedure.

Examples include:

  • Iron supplements (which can coat the colon lining)

  • Blood thinners such as warfarin (Coumadin®)

Most medications for blood pressure, heart disease, lung conditions, and seizures can usually be taken on the day of the test.

Patients with diabetes may require medication adjustments before the examination. Always consult your doctor for specific guidance.


What Happens During a Sigmoidoscopy?

Flexible sigmoidoscopy is a quick procedure, usually lasting 5–15 minutes.

During the procedure:

  1. You will lie on your left side with your knees bent.

  2. The doctor gently inserts a thin flexible tube called a sigmoidoscope into the rectum.

  3. The scope contains a camera and light, allowing the doctor to view the colon on a monitor.

During the examination, the doctor may:

  • Take biopsies (small tissue samples for laboratory testing)

  • Remove polyps

  • Introduce air to expand the colon for better visibility

Biopsies do not cause pain, but you may experience mild cramping or pressure during the procedure.

Because the procedure is short and generally well tolerated, sedation is usually not required.


Possible Complications

Flexible sigmoidoscopy is a very safe procedure, and complications are uncommon.

Rare complications may include:

  • Minor bleeding, especially after biopsy or polyp removal

  • Perforation (tear) in the colon wall, which is very rare

Contact your doctor immediately if you experience:

  • Severe abdominal pain

  • A swollen or firm abdomen

  • Vomiting

  • Fever

  • Significant rectal bleeding


Recovery After Sigmoidoscopy

Most patients tolerate the procedure very well.

After the examination:

  • You can usually return to normal activities immediately

  • Eating and drinking can resume as usual

  • Many patients can drive and return to work the same day

Your doctor will discuss the results of the procedure and inform you if further testing or treatment is required.
