Endoscopy: A Simple and Accurate Diagnostic Procedure for Gastrointestinal Disorders
Gastrointestinal abnormalities often present with vague or subtle symptoms, causing many people to overlook them until the condition becomes more severe. This can make treatment more difficult in later stages. Therefore, gastrointestinal endoscopy plays a crucial role in early detection of hidden lesions before the disease progresses.
Why Endoscopy Matters Endoscopy is a highly accurate and detailed diagnostic tool that can detect even minor abnormalities. It allows for tissue biopsy without the need for surgery. It is especially recommended for patients with chronic abdominal pain that does not improve with medication, or those experiencing additional symptoms such as unexplained weight loss, loss of appetite, persistent vomiting, or those over 45 years old with gastrointestinal symptoms - as the risk of serious diseases increases with age. It is also crucial for patients with gastrointestinal bleeding, such as vomiting blood, black or bloody stools, or a positive fecal occult blood test. Patients with unexplained chronic diarrhea should also consider undergoing endoscopic evaluation.

Types of Gastrointestinal Endoscopy
- Upper Gastrointestinal Endoscopy (Gastroscopy):
This procedure uses a small flexible tube equipped with a camera to examine the upper part of the digestive tract. The tube is inserted through the mouth to inspect the esophagus, stomach, and the duodenum (the first part of the small intestine). Gastroscopy is typically performed on patients with symptoms such as difficulty swallowing, chronic abdominal pain, or persistent upper abdominal bloating and discomfort with no identifiable cause. It is also used in cases of vomiting blood. This procedure can detect stomach ulcers, gastrointestinal bleeding, or tumors within the upper digestive tract.
- Colonoscopy (Lower Gastrointestinal Endoscopy):
This involves inserting a small flexible tube through the rectum to examine the entire colon and sometimes the end of the small intestine. It is generally performed in patients who have persistent bowel issues such as chronic diarrhea, constipation, alternating diarrhea and constipation, blood in the stool, or an abdominal mass. It is also recommended for those at risk of colorectal cancer or polyps. Regular colonoscopy screening is advised for individuals aged 45 and older, with follow-up every 5–10 years, to detect conditions such as colitis, diverticulosis, polyps, or colorectal tumors.
