Diagnosis Of Digestive Disorders

Digestive disorders are diagnosed in the following ways:

Common Diagnostic Tests

Endoscopy: An examination involving the passage of a flexible tube which contains a camera to view the upper digestive system; including the oesophagus, stomach and duodenum. In this regard, it assists in diagnosing conditions such as ulcers, inflammation and even tumours.

Colonoscopy: A technique that entails the use of a long narrow telescope that is passed through the rectum and the colon to examine the large intestine. This is useful in the diagnosis of colorectal cancer, adenomatous colonic polyps as well as inflammatory bowel disease.

Imaging Tests: Uses procedures like radiography, computerised axial tomography or CAT scans, magnetic resonance imaging or MRI to locate and assess the condition of the internal organs of the digestive system including tumours, obstructions or inflammation.

Blood Tests And Stool Tests

Blood Tests: They are employed in diagnosing inflammation, infection, anaemia, as well as the liver’s functional capacity. Serum enzymes and other clinical lab tests like LFTs and CBC give information about digestive wellness.

Stool Tests: Treat for infections, blood, or irregularity in the manner in which food passes through the digestive system as seen from the faeces. It can help detect parasites, bacteria presence or the presence of diseases such as celiac disease or inflammatory bowel disease.

Biopsy Procedures

Biopsy: These includes obtaining a small tissue biopsy from the gut tissue to examine using the microscope. They diagnose one for cancer, chronic inflammation or an infection. Endoscopic biopsies are frequently curative, and the results are as specific about tissue pathology as are biopsy results.
