Our health is the most valuable asset in our lives, and one of the most effective ways to protect this valuable asset is by having regular health check-ups. Colonoscopy is an important part of these check-ups and a critical step in maintaining colorectal health. In this article, detailed information will be provided about the definition, importance, procedure, diagnosis, and treatment possibilities of a colonoscopy. What is a Colonoscopy? A colonoscopy is a medical procedure used to examine the inner surface of the large intestine (colon). This examination is performed with a camera placed inside a flexible tube. Colonoscopy allows for the inspection of the colon for polyps, tumors, inflammations, or other abnormal conditions.
The Importance of Colonoscopy:
- Early Diagnosis: Colonoscopy is used to detect issues such as colon cancer at an early stage. Early diagnosis can significantly increase the chances of treatment.
- Polyp Removal: During a colonoscopy, doctors can identify and remove polyps. Early removal is vital as polyps have the potential to turn into cancer.
- Diagnosis and Monitoring: Colonoscopy is used to make a definitive diagnosis and determine treatment processes for individuals experiencing bowel problems. It can also be used for regular monitoring in individuals with a history of polyps or tumors.
How is a Colonoscopy Performed?
A colonoscopy usually involves preparations that last a day. After these preparations, the colonoscopy is performed with the patient's consent. The specialist doctor advances the thin tube along the colon starting from the rectum and simultaneously views the images on a screen. Colonoscopy and Conscious Health: Colonoscopy is an important part of conscious health management. This procedure is recommended at regular intervals for individuals of certain age groups and risk factors. Diagnosing health issues at an early stage can facilitate treatment processes and improve the quality of life.
Frequently Asked Questions
What are Intestinal Diseases?
Intestinal diseases encompass various disorders affecting the intestines, which are a crucial part of the digestive system. The most common among these are irritable bowel syndrome, diverticulitis, polyps, ulcerative colitis, and Crohn's disease.
Such diseases manifest themselves with symptoms like abdominal pain, diarrhea, constipation, bloating, and changes in bowel habits.
Regular implementation of imaging methods like colonoscopy is recommended for early diagnosis.
How Long Does a Colonoscopy Take?
How long a colonoscopy takes is one of the most curious questions for those undergoing the procedure for the first time. It usually completes within 20 to 40 minutes.
The duration of the procedure can vary depending on the patient's bowel structure, bowel cleanliness, and whether there are additional applications such as polyp removal during the procedure.
Under sedation (mild anesthesia), the patient does not feel any pain or discomfort. Including observation time post-procedure, the total clinical process can take approximately 1–2 hours.
What Should Be Considered Before a Colonoscopy?
Preparation before a colonoscopy is critical for the success of the procedure. A completely empty bowel ensures clarity in imaging.
The following should be considered before a colonoscopy:
-
A 3-day colonoscopy diet should be followed as per the doctor's recommendation
-
Foods that are non-fibrous and non-gas-producing should be preferred
-
Only liquid foods should be consumed the day before the procedure
-
Prescription medications for bowel cleansing should be used completely
-
If necessary, blood-thinning medications may be discontinued before the procedure
Detailed information should be provided by your doctor before a colonoscopy and adjusted according to individual health conditions.
What is Ulcerative Colitis?
Ulcerative colitis is a chronic intestinal disease caused by inflammation of the lining of the large intestine.
This disorder, evaluated within the group of bowel diseases, usually starts in the rectum and can spread to the entire colon.
Symptoms include frequent and bloody diarrhea, abdominal pain, weakness, fever, and weight loss.
The disease shows periodical flare-ups and remissions. The treatment process is handled with anti-inflammatory drugs, immune regulators, and special diets.
In some cases, surgical intervention may also be necessary.
What is Crohn's Disease?
Crohn's disease is a chronic inflammatory bowel disease of autoimmune origin that can affect any part of the digestive system. It is most commonly seen at the junction of the small intestine and the large intestine.
Its symptoms appear as abdominal pain, diarrhea, weight loss, and fatigue, similar to ulcerative colitis.
This disease can affect all layers of the intestinal wall and cause complications such as narrowing and obstruction.
When Crohn's disease is diagnosed, the extent and severity of lesions are assessed with a colonoscopy.
Treatment aims at reducing flare-ups and keeping symptoms under control.
How is a Colonoscopy Performed?
The question of how a colonoscopy is performed is an important guide for those curious about the procedure. Colonoscopy provides an inside view of the large intestine with the help of a thin, flexible camera.
The patient is mildly sedated. Then the colonoscope device is advanced through the anus, and all structures along the bowel are examined.
Abnormalities such as polyps, lesions, and bleeding sites can be detected. If necessary, a biopsy can be taken, or a polyp removed at the same time.
The patient does not feel pain during the procedure but may experience temporary gas and cramps afterward.
How is a 3-Day Colonoscopy Diet Implemented?
The main aim of the diet before a colonoscopy is to clear the bowels of residues to ensure a clear view during the procedure. A 3-day colonoscopy diet can be implemented as follows:
-
3 days before: Foods without fiber such as vegetable-free soup, yogurt, boiled white rice
-
2 days before: Broth, yogurt, white bread, peeled potatoes
-
1 day before: Only liquid foods (broth, fruit juice, tea)
Nothing should be eaten or drunk 6 hours before the procedure.
Personal adaptations can be made in the diet application before a colonoscopy. The bowel cleansing medications provided by the doctor should be used precisely.
Why is the Diet Before a Colonoscopy Important?
The diet before a colonoscopy enhances the accuracy and effectiveness of the procedure by ensuring bowel cleanliness.
If the bowel is not adequately cleaned, polyps, tumors, or inflamed areas may be overlooked, leading to misdiagnoses or repeated procedures.
The diet before colonoscopy also reduces the risk of complications during the procedure and shortens the procedure time.
Complete adherence to the diet directly affects the success of the procedure for both the patient and the doctor.
What is Irritable Bowel Syndrome (IBS)?
Irritable bowel syndrome is a condition characterized by abdominal pain, bloating, diarrhea, or constipation that causes functional discomfort without any structural abnormality.
IBS is chronic and may flare up with environmental factors such as stress and dietary habits. Diagnosis is made by excluding other diseases.
Treatment typically involves dietary regulation, probiotics, bowel-regulating medications, and stress management techniques.
What are Polyps and Why are They Important?
Intestinal polyps are small growths similar to skin tags on the inner surface of the intestine. They are usually benign but some types of polyps can turn into cancer over time.
Polyps detected during a colonoscopy can often be removed in the same session. Pathological examination determines the type and risk of the polyp.
Early detection of polyps through regular screening is crucial to reducing the risk of bowel cancer. Therefore, screening colonoscopies are recommended for individuals over 50.
