Currently, “colorectal cancer” and “gastrointestinal diseases” are among the top health issues affecting quality of life. However, with modern medical technology, endoscopy has become a key tool that allows us to “see” internal abnormalities from the early stages without the need for major open surgery.

1. Get to know the 2 main types of endoscopy

• Gastroscopy (Upper Gastrointestinal Endoscopy): Used to examine the esophagus, stomach, and duodenum to find the causes of upper abdominal pain, stomach ulcers, or bacterial infections.

• Colonoscopy: Used to check for polyps or abnormalities throughout the entire large intestine, making it the best method for colorectal cancer screening. If a polyp is found, the doctor can remove it immediately.

2. Warning signs… that require a doctor visit If you or someone close to you experiences any of these symptoms persistently for over 2 weeks, they should not be ignored:

• Chronic abdominal pain, bloating, or frequent heartburn.

• Changes in bowel habits, such as alternating constipation and diarrhea, or narrower stool size.

• Blood in the stool (either bright red or dark black).

• Unexplained weight loss, or symptoms of pale skin and fatigue.

3. Advantages of modern endoscopy

• High precision: High-resolution internal imaging helps doctors make accurate diagnoses.

• Minimal pain, fast recovery: Since it is performed through natural body openings, there are no external surgical incisions.

• Comfortable sleep during the procedure: Short-acting sedatives are administered under medical supervision, ensuring patients feel no pain or anxiety during the procedure.

• Simultaneous diagnosis and treatment: If an problematic area is found, the doctor can take a tissue sample for biopsy or remove polyps right away.

4. Simple preparation for accurate results

• Fast from food and water: At least 6–8 hours according to the doctor’s instructions.

• Bowel preparation: (For colonoscopy) Laxatives must be taken as prescribed to thoroughly clean the bowel, helping doctors clearly spot small lesions.

• Disclose medical history: Especially regarding blood-thinning medications or other underlying conditions.

Endoscopy is not something to be feared, but rather an “opportunity” to detect severe diseases before they progress. Especially individuals aged 50 and above, or those with a family history of colorectal cancer, should undergo regular screening for sustainable good health.

Additional advice: After undergoing endoscopy using sedatives, patients should be accompanied by a relative and “refrain from driving any type of vehicle” for at least 24 hours for safety.
