What diseases can be detected through a colonoscopy?

Generally speaking, colonoscopy refers to a procedure used to examine the colon. Colonoscopy can detect various diseases such as intestinal polyps, colitis, intestinal parasitic infections, intestinal bleeding, intestinal strictures and obstructions. If experiencing any discomfort, it is recommended to seek medical attention immediately. Detailed explanations are as follows:

1. Intestinal Polyps

Colonoscopy allows direct visualization of the mucosal condition inside the intestine. Intestinal polyps are benign growths on the intestinal mucosa, although certain types carry a risk of malignancy. Through colonoscopy, physicians can evaluate the size, shape, and location of the polyps.

2. Colitis

Colitis may be caused by bacterial or viral infections and other factors. Patients may experience symptoms such as congestion, edema, and erosion of the intestinal mucosa. Colonoscopy enables clear visualization of intestinal lesions, and biopsy can help determine the type and severity of inflammation.

3. Intestinal Parasitic Infection

Colonoscopy can detect characteristic lesions caused by parasites on the intestinal mucosa, such as ulcers and nodules. Additionally, colonoscopy allows sampling of parasites for further pathogen testing.

4. Intestinal Bleeding

Intestinal bleeding is a common symptom of diseases such as intestinal ulcers, intestinal inflammation, and intestinal tumors. Colonoscopy can locate the bleeding site and identify the underlying cause.

5. Intestinal Strictures and Obstruction

Intestinal strictures and obstruction may be caused by tumors, inflammation, scars, and other factors. Colonoscopy allows direct visualization of the narrowed areas and enables assessment of the severity of the stricture.

Maintaining healthy lifestyle habits, regular作息 (作息 likely refers to作息 time or rest patterns), moderate exercise, and a balanced diet in daily life can help prevent the occurrence of intestinal diseases.
