Diagnostic process of tenesmus disease
A proper diagnosis of tenesmus starts with understanding the patient’s symptoms, bowel habits, medical history,
and any associated problems such as bleeding, constipation, or pain. Depending on the findings, the doctor may
recommend a rectal examination, blood or stool tests, proctoscopy, or colonoscopy to identify the underlying
cause.
1. Digital rectal examination
A digital rectal examination allows the doctor to check the anal canal and lower rectum for possible
abnormalities. It may help identify piles, tenderness, swelling, impacted stool or unusual growths. The doctor may
also assess anal muscle tone and look for signs of pelvic floor dysfunction that could contribute to incomplete
bowel movements.
2. Proctoscopy or anoscopy
Proctoscopy or anoscopy may be recommended to examine the anal canal and lower rectum more closely. These tests
help the doctor identify conditions such as internal piles, anal inflammation, rectal irritation or other visible
abnormalities that may cause discomfort and repeated bowel urgency.
3. Colonoscopy
A colonoscopy allows the doctor to examine the lining of the colon
and rectum using a flexible camera. It may be recommended when symptoms persist or when the doctor suspects
inflammatory bowel disease, polyps, tumours or other colorectal conditions. During the procedure, tissue samples
may also be collected for further examination if needed.
4. Blood or stool tests
Blood or stool tests may help identify underlying conditions associated with tenesmus. Blood tests can check for
anaemia or signs of inflammation, while stool tests may detect infections, intestinal inflammation or hidden
blood. The doctor will recommend specific tests based on the patient's symptoms, medical history and examination
findings.
